Morphological and morphometrical studies of females, perineal pattern, second stage juveniles and males of root knot nematodes collected from Dhanuvachapuram, Kattakada and Vellayani of Thiruvananthapuram district; Balagram, Pampadumpara and Thovalappady of Idukki district; Chazhoor, Thalikulam and Thaniyam of Thrissur district infecting brinjal, okra, tomato and banana were done and the data was analysed to identify the species. M.incognita (Kofoid & White, 1919) Chitwood, 1949, M. javanica (Treub, 1885) Chitwood, 1949, M. arenaria (Neal, 1889) Chitwood, 1949 and M. chitwoodi Golden, O'Bannon, Santo & Finley 1980 were identified from brinjal, okra, tomato and banana in Thiruvananthapuram, Idukki and Thrissur districts of Kerala. The study indicated M. incognita as the major species of root knot nematode in Thiruvananthapuram district (91.66%) with highest percentage of occurrence in brinjal and tomato (27.77). In Idukki district, the major species of root knot nematode was M. javanica (66.66%) with highest percentage of occurrence from brinjal and banana (33.33). In Thrissur district, M. arenaria was found to be the major species (66.66%) with highest percentage of occurrence in okra (37.5). M. incognita was found to be the major species in brinjal (55.55%), okra (44.44%), tomato (55.55%) and banana (44.44%) in Thiruvananthapuram, Idukki and Thrissur districts. The extent of parthenogenesis of root knot nematode was found to be very high (97.22%) in these populations. Intraspecific morphological variations were observed within M. incognita, M. javanica and M. arenaria with respect to shape of females, length and position of neck, perineal pattern morphology, tail characters including rectum dilation. Interpopulation comparison of mature females, perineal pattern and second stage juveniles of M. incognita showed that the characters length, width, neck length, stylet length, LMB, WMB and ratio a of females, LVS, AVS, ATT and IPD of perineal pattern and body length, stylet length, H-MB, ABW, tail length, ratio c and c’ were recorded as stable characters. Interpopulation comparison of mature females, perineal pattern and second stage juveniles of M. javanica showed that all the characters of females, perineal pattern and second stage juveniles were stable characters and in M. arenaria, the characters like body length, width, neck length, stylet length, LMB and WMB of females, LVS, AVS, ATT and IPD of perineal pattern and length, stylet length, H-MB, ABW and tail length were recorded as stable characters and found useful in characterizing species. Intraspecific morphological and morphometric variations of M. incognita, M. javanica, M. arenaria were recorded from four host plants in three districts in Kerala. M. arenaria and M. javanica showed high variability between the populations compared to M. incognita in Kerala. The study indicated that M. incognita, M. javanica and M. arenaria were the major species infesting vegetables and banana in Kerala. Among the sampled populations, M. hapla was not identified which shows that M. hapla is not common in Kerala conditions. The study recorded the first report of species having morphological and morphometrical characters similar to M. chitwoodi from okra in Thiruvananthapuram which opens way to molecular studies in future.ThesisItem Open Access Standardisation of spacing and nutrient levels for fodder rice bean [Vigna umbellata (Thunb.)].(Department of Agronomy, College of Agriculture, Vellayani, 2018) Ajmal Fayique, C; KAU; Usha C, ThomasThe study entitled “Standardization of spacing and nutrient levels for fodder rice bean [Vigna umbellata (Thunb.)]” was conducted at College of Agriculture, Vellayani, Kerala during Kharif 2017 to standardize the spacing and nutrient requirement of fodder rice bean and to study its impact on growth, yield and quality of the crop. The experiment was laid out in Randomised Block Design (33 confounded factorial) with three replications.The treatments consisted of three spacings (s1 - 30 cm x 10 cm, s2 - 30 cm x 20 cm and s3 - 30 cm x 30 cm), three levels of nitrogen (n0 - 0 kg ha-1, n1 - 20 kg ha-1 and n2 - 30 kg ha-1) and three levels of phosphorous (p0 - 0 kg P2O5 ha-1, p1 - 20 kg P2O5 ha-1 and p2 - 40 kg P2O5 ha-1) . FYM @ 5 t ha-1 and K2O @ 30 kg ha-1 were applied uniformly to all treatments as basal. The treatment s1 resulted in the highest plant height at 30 DAS and leaf: stem ratio at harvest. Application of N @ 20 kg ha-1 registered the highest plant height and was on par with 30 kg N (n2) while leaf stem ratio was the highest at n2. Levels of P had no significant impact on growth characters. The treatment combination s2n2p1 produced the tallest plants (173.17 cm) at harvest and treatments s1n0p1 and s1n2p2 recorded the highest leaf: stem ratio (0.82) but were on par with s1n0p0, s2n0p0, s n0p2, s1n1p0, s2n0p2 and s3n0p1. At 30 DAS, s1 produced the highest LAI (2.27) while at harvest, s2 was found superior. The highest NAR was observed at s1 and was on par with s3. Closer spacing (s1) enhanced the CGR at 30 DAS and harvest. Application of 30 kg N ha-1 (n2) enhanced LAI at both stages. At 30 DAS and at harvest, higher NAR were observed at n1 and n2. At 30 DAS, n2 and p1 registered the highest chlorophyll contents. The treatment s1 n2 p1 (30 cm x 10 cm spacing + 30 kg N ha-1 + 20 kg P2O5 ha-1) resulted in the highest LAI, CGR and chlorophyll content at 30 DAS. Spacing and N levels had significant impact on green fodder yield (GFY) and dry fodder yield (DFY). The highest GFY (12.95 t ha-1) and DFY (2.59 t ha-1) were produced at s1 (30 cm x 10 cm) and was on par with s2. The highest GFY (13.66 t ha-1) and DFY (2.73 t ha-1) were produced at n2 (30 kg N ha-1) and was on par with n1. The S x N x P interaction s1 n2 p1 (30 cm x 10 cm + 30 kg N ha-1 + 20 kg P2O5 ha-1) recorded highest GFY (17.29 t ha-1) and DFY (3.46 t ha-1). The different spacing had no impact on crude protein (CP) but the lowest crude fibre (CF) was observed at s1. Application of 30 kg N ha-1 (n2) resulted in the highest CP content and the lowest CF content was estimated at 0 kg N ha-1. Among P levels, p2 recorded the highest CP (17.69%) and was on par with p1. The lowest CF (16.43 %) was observed at s2n0p1 (30 cm x 20 cm spacing + 20 kg P205 ha-1) and was on par with s1n0p0, s1n0p1, s1n2p0, s2n0p0, s2n0p2, s3n0p0 and s3n0p1. No variation in N uptake was observed due to treatments. Uptake of P varied with N levels only and n1 and n2 recorded the highest P uptake. Spacing and P levels influenced K uptake by the crop and the highest uptake was observed at s1 and p2 but p2 was on par with p1. The three factor interaction s1n2p1 registered the highest P and K uptake. However, it was on par with s1n1p2, s1n1p0, s2n1p1 and s3n0p2 in P uptake and with s1n2p2 in K uptake. Increasing N levels increased pH and EC of soil after the experiment. Soil available N after the experiment was the highest at s3 (on par with s2) and n2 (on par with n1). At wider spacing, application of N enhanced the availability of N in the soil after the experiment. Available P in the soil varied with S x P interaction but all treatment combinations were on par except s2p0 and s3p2. The highest soil available K was observed at n0 among N levels and at p1 among P levels. The interactions S x N, S x P and N x P significantly influenced available K in the soil. Economic analysis revealed the highest net income (₹ 35762) and BC ratio (3.22) at s1n2p1 (30 cm x 10 cm spacing + 30 kg N ha-1 + 20 kg P2O5 ha-1). From the study, it can be concluded that fodder rice bean can be profitably cultivated at a spacing of 30 cm x 10 cm with application of 30 kg N ha -1 in two splits at 15 and 30 DAS and basal application of 20 kg P2O5 ha-1, 5 t ha-1 of FYM and 30 kg K2O ha-1.ThesisItem Open Access Cryopreservation of chethikoduveli (Plumbago rosea L.) and assessment of genetic fidelity of regenerated plantlets using molecular markers(Department of Plant Biotechnology, College of Agriculture, Vellayani, 2014) Anand, Vishnu Prakash; KAUInvestigations on “Cryopreservation of Chethikoduveli (Plumbago rosea L.) and assessment of genetic fidelity of regenerated plantlets using molecular markers” were carried out at the Department of Plant Biotechnology, College of Agriculture, Vellayani during 2011-2013. Plumbago rosea var. Agni plants were collected from AMPRS, Odakkali, Ernakulam and maintained at the Department of Plant Biotechnology, College of Agriculture, Vellayani as source of explant during the course of the study. The objectives of the present study was to standardise cryopreservation protocol by encapsulation dehydration technique for long term conservation of P. rosea and genetic fidelity assessment of plantlets recovered and regenerated from cryostorage using molecular markers. The project was carried out in two phases viz., in vitro regeneration and in vitro conservation by cryopreservation of P. rosea. In vitro regeneration protocol was optimised for P. rosea var. Agni. Various steps of in vitro regeneration viz., surface sterilization, axillary shoot proliferation, in vitro rooting and acclimatization and planting out has been standardised. For surface sterilizing, single nodal explants (3-4 cm long) were subjected to fungicide treatment with 0.1 per cent carbendazim 50 per cent W. P. (for 30 min) followed by aseptic sterilisation dip with absolute alcohol. Further, the explants were surface sterilised with 0.2 per cent mercuric chloride (for 5 min) which gave 100 per cent survival without any contamination. Enhanced release of axillary buds from single nodal explants, with maximum shoot proliferation (5.28 shoots/culture) was obtained in the medium, MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1. The best response (10.67 roots/culture) of in vitro rooting of plantlets was obtained in the medium, MS + NAA 1.0 mg l-1. In vitro rooted plants gave a maximum survival rate of 76 per cent and 72 per cent, when planted out in potting media consisting of red soil and coir pith (3:1) and red soil and coir pith (2:1) supplemented with VAM respectively at 25 per cent shade. In cryopreservation studies, preconditioning treatment (sucrose 0.5 M for 7 days) recorded maximum shoot proliferation (2.67 shoots/culture) when nodal segments with single axillary bud were cultured on MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1 medium. Among different encapsulation treatments, maximum shoot proliferation of (2.31 shoots/culture) was obtained in beads formed with sodium alginate 2.5 per cent and calcium chloride 100 mM, when cultured on the medium, MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1. Pre-culture medium supplemented with sucrose 0.5 M for 3days gave maximum shoot proliferation (3.44 shoots/culture) when cultured on the medium, MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1. A desiccation duration of 5 h at 18.13 per cent moisture level was found to be most effective giving 66.67 per cent survival and 62.50 per cent regeneration on thawing and culturing on the recovery medium MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1. The beads when stored in liquid nitrogen for different duration and cultured on recovery medium did not show any significant variation with respect to survival per cent. RAPD markers were tried to study the genetic fidelity of the regenerated plantlets from encapsulated and cryopreserved axillary buds. Six primers were screened and RAPD banding patterns of the cryoregenerated plantlets and control plants were compared. Polymorphism was not found with any of the primers tested. RAPD profiles of cryoregenerated plantlets were identical to those of the control. The in vitro regeneration protocol optimized included surface sterilization of single node cuttings with 0.2 per cent HgCl2 for 5 min, axillary shoot proliferation in MS medium supplemented with BA 1.5 mg l-1 and IAA 1.0 mg l-1, in vitro rooting in MS medium supplemented with NAA 1.0 mg l-1 and planting out in potting medium, red soil and coir pith (3:1). The protocol for encapsulation dehydration technique of cryopreservation was standardised for the axillary buds of P. rosea with preconditioning in semi solid MS medium supplemented with sucrose 0.5 M for 7 days, encapsulation using sodium alginate 2.5 per cent and calcium chloride 100 mM followed by pre-culture in liquid MS supplemented with sucrose 0.5 M for 3 days and 5 h dehydration (MC 18.13 %), rapid freezing in LN for at least 2 h and recovery in the medium MS + BA 1.5 mg l-1 + IAA 1.0 mg l-1. The cryopreservation protocol using encapsulation-dehydration technique standardised could be utilised for long-term conservation of P. rosea.ThesisItem Open Access Management of bitter gourd mosaic by enhancing host resistance(Department of Plant Pathology, College of Horticulture, Vellanikkara, 2015) Ashwini, K N; KAU; Vimi, LouisBitter gourd (Momordica charantia L.) is one of the important vegetable crops that occupy a pivotal position among fruit vegetables, particularly in south India. The fruits of this crop which have high commercial value and are being used for culinary preparations and various medicinal preparations. In spite of the economic importance of this vegetable, the research work carried out on protection of crop from viral disease is quite scanty. In many case, cent per cent mosaic incidence was recorded in the crop resulting in substantial economic loss. So the present study was focused on screening of bitter gourd accessions and management of bitter gourd mosaic by enhancing host resistance using defense inducers. The three different viruses causing mosaic in bitter gourd are cucumber mosaic virus (CMV), potyvirus and bitter gourd distortion mosaic virus (BDMV). As these viruses causes mixed infection in field, the separation of individual viruses was carried out using systemic indicator host plants. For separation of CMV and potyvirus, systemic indicator host plants used were cosmos and papaya respectively. BDMV was separated by white fly transmission. The pure cultures of viruses were maintained on the susceptible bitter gourd variety Preethi. The symptoms developed by different viruses were recorded under natural and artificial conditions were recorded CMV produced mosaic specks, yellow-green mosaic patches, leathery leaves and downward rolling of leaf margin. Symptoms of potyvirus infection were vein clearing, puckering, malformed leaf with reduced leaf size and rugosity. BDMV infection produced mosaic, puckering, leaf distortion, hairy growth on leaves and vines with reduction in leaf size and internodal length. For the screening of bitter gourd accessions against CMV and potyvirus, potassium phosphate buffer pH 7.0 was found to be the most suitable buffer. Among 22 accessions screened, three accessions viz., TCR 285, TCR 39 and TCR 53 were highly resistant to CMV; one accession Biliagala was highly resistant to potyvirus and 11 accessions viz.,TCR 285, TCR 39, TCR 493 ,TCR 416, TCR 492, TCR 494,TCR 380, TCR 202 and TCR 149, Green long and Biliagala were highly resistant to BDMV. The field experiment was undertaken with the objective of management of bitter gourd mosaic by using defense inducers. The three different defense inducers viz., salicylic acid 25 ppm, barium chloride 0.1% and Pseudomonas fluorescens 2 % were evaluated on the moderately resistant cultivar white long and susceptible variety Preethi. The mosaic symptom was recorded after 51 days of sowing in salicylic acid treated plants and after 40 days of sowing in control. A time gap of 5-10 days after spray of defense inducer was required for development of resistance in plants. The lowest disease severity was observed in cultivar White long treated with salicylic acid. The highest yield was recorded in Preethi treated with Pseudomonas fluorescens.ThesisItem Open Access Management of banana pseudostem weevil odoiporus longicollis oliv.using entomopathogenic fungi(Department of Agricultural Entomology, College of Agriculture, Vellayani, 2005) Sahi Beegum, M K; KAU; Anitha, NInvestigation on “Management of banana pseudostem weevil, Odoiporus longicollis Oliv. using entomopathogenic fungi” was carried out in the Department of Agricultural Entomology, College of Agriculture, Vellayani. The study was conducted to screen four entomopathogenic fungi, to evaluate their biocontrol potential and to standardize the effective dose and method of application for the management of the banana pseudostem weevil. Four entomopathogenic fungi viz., Metarhizium anisopliae, Beauveria bassiana, Paecilomyces lilacinus and Nomuraea rileyi were tested against O. longicollis. Among them M. anisopliae and B. bassiana were found to infect O. longicollis grubs. Susceptibility of different stages of grubs to fungal infection was tested by using first, second, third, fourth and fifth instar grubs of O. longicollis and the results revealed that first and second instar grubs were more susceptible to fungal infection. Determination of effective dose of fungi against second instar grubs of O. longicollis was carried out by spraying the grubs with different concentrations of M. anisopliae and B. bassiana. The LC50 values of M. anisopliae and B. bassiana were 3.9 x 106 spores ml-1 and 1.6 x 105 spores ml-1 respectively. Evaluation of six naturally available solid media viz., rice bran, wheat bran, guinea grass, gingelly oil cake, coir pith, and neem cake were carried out for mass multiplication of M. anisopliae and B. bassiana. The results revealed that both rice bran and wheat bran were suitable for the mass multiplication of these fungi. The spore production was 9.26 x 106 spores ml-1 and 8.71 x 106 spores ml-1 respectively for M. anisopliae on first week after inoculation. For B. bassiana, the spore count was 503.42 x 106 spores ml-1 and 320.32 x 106 spores ml-1 respectively on first week after inoculation. Among the liquid media tried, coconut water and rice bran extract produced maximum mycelial growth and sporulation of fungi. For M. anisopliae the spore count was 7.77 x 107 spores ml-1 and 0.49 x 107 spores ml-1 respectively. B. bassiana recorded 440.03 x 106 spores ml-1 and 232.26 x 106 spores ml-1 respectively. M. anisopliae and B. bassiana grown in rice bran and wheat bran recorded maximum virulence on two weeks after storage and decreased thereafter. However, coconut water and rice bran extract showed maximum virulence on first week after storage and then found decreasing. Studies conducted to evaluate the compatibility of fungi with NeemAzal 0.4 per cent, chlorpyriphos 0.03 per cent, copper oxychloride 0.4 per cent and mancozeb 0.3 per cent revealed that all the pesticides tested inhibited the growth of M. anisopliae and B. bassiana. But the per cent inhibition was least in the case of NeemAzal 0.4 per cent. Field experiments were conducted with M. anisopliae and B. bassiana with chlorpyriphos (0.03 per cent) and NeemAzal (0.4 per cent) as checks. The plants were artificially infested with known number of grubs. Two experiments were conducted, one with prophylactic treatments and the other with curative treatments. Three application methods viz., leaf axil filling of spore suspension of M. anisopliae and B. bassiana, leaf axil filling of fungi in rice bran and stem injection of spore suspension were tested. Among these treatments leaf axil filling of B. bassiana spore suspension at 1.8 x 107 ml-1 as prophylactic treatment was most effective which gave 52.42 per cent mortality of grubs.ThesisItem Open Access Etiology and ecofriendly management of fungal diseases of thippali ( piper longum L)(Department of Plant Pathology, College of Agriculture, Vellayani, 2007) Poornima, R; KAU; Santha Kumari, PA survey was carried out at the medicinal garden of College of Agriculture, Vellayani and medicinal garden of Ayurveda Research Institute, Poojappura, Thiruvananthapuram to study the diseases associated with Piper longum L. (Indian long pepper or thippali). The major disease observed was anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz and Sacc. Pathogenicity test proved that C. gloeosporioides was the pathogen associated with the disease. Cross inoculation studies conducted using C. gloeosporioides isolate of thippali, black pepper and betel vine - the sister plants – showed that the thippali isolate was highly host specific. The colony and conidial morphology of the three isolates also showed considerable difference. C. gloeosporioides of thippali had very small conidia and the culture was also found to be shy sporulating. Studies on the survival of C. gloeosporioides showed that the pathogen survived for 105 days in the infected leaves, under laboratory conditions. In the soil, it survived for 150 days. Of the eleven fungal and four bacterial isolates tested against C. gloeosporioides, T. viride and A.terreus were found to be most effective under in vitro condition. Among the different resistance inducers tested in vitro, SA (1 g/l) was selected for field evaluation, as it had no direct action on the pathogen. Of the two plant based chemicals tested, Ovis reported the highest suppression of the pathogen. These four eco friendly materials selected from the in vitro studies and neem cake were tested in the field to determine their effectiveness in controlling the disease. Their combinations were also studied. Among the different eco friendly materials tested in the field, treatment T12 (T2T5 - A. terreus + neem cake) was found to be best in disease suppression at 45 DAT. Estimation of DRE showed that PO and PPO activity was highest in T3 (Ovis) where as PAL activity was maximum in T1 (T. viride). Combination of treatments revealed that maximum PO activity was in treatment T14 (T3T5 - Ovis + neem cake).The PPO and PAL activity was maximum in T7 (T1T3 - T. viride + Ovis).ThesisItem Open Access Nonlinear models for major crops of Kerala(Department of Agricultural Statistics, College of Horticulture, Vellanikkara, 2007) Joshy, C G; KAU; Krishnan, SNonlinear modelling techniques are the most suited tools for describing any time series phenomenon. Among the various nonlinear models in vogue monomolecular, logistic, gompertz and mixed-influence models find a prominent place. With this idea the agricultural scenario of Kerala was measured through the three important descriptors namely area, production and productivity of the major crops viz; coconut, rubber, paddy, pepper, tapioca, cashew and banana for all the districts and the state as such. Monomolecular model was the most apt model in most of the cases. The data sets were further explored based on the carrying capacity achieved by 2002-03 coupled with intrinsic growth rate. When none of the nonlinear models were found satisfactory either simple linear regression model or quadratic model was tried to explore the nature of trend. Coconut production was found to have reached its near maximum in all the districts where it was a major crop but the productivity figures gave a warning note for increasing the productivity. Rubber was found to be one of the most gifted crops, which was not devoid of proper attention. Even with this stature, production of rubber can be improved through uniform management practices. Usually nonlinear and quadratic models aptly describe a time series data on crop production. It is astonishing that simple linear regression model aptly described the paddy production in the state. The regressive value of the regression coefficients indicated that paddy production in the state is facing extinction.Paddy production in the state has at least to be protected. The lack of fit of most of the nonlinear models and even quadratic models to the data of pepper production indicate the various devastating hazards that the crop faced with. These contrasting features bring out the fact that pepper cultivation be not allowed to be toyed with. The area specific crops like cashew, cardamom, coffee and banana be made nonspecific through innovative technologies. A concerted effort with valid stresses specific to each crop will make the agricultural scenario bright.ThesisItem Open Access Group marketing system for fruits and vegetables in Kerala(Department of Rural Marketing Management, College of Co operation and Banking Management, Vellanikkara, 2007) Bibin, Mohan; KAU; Philip, SabuThe study entitled “Group marketing system for Fruits and vegetables in Kerala” was undertaken with the following objectives: To analyse the marketing behaviour of commercial fruits and vegetables farmers and to evaluate the structure, conduct and performance of Swasraya Karshaka Samithies (SKSs) promoted by Vegetable and Fruit Promotion Council, Keralam (VFPCK). The study was conducted in Thrissur and Palakkad districts which accounted for the largest volume of business through SKSs. Commercial farmers and traders of fruits and vegetables constituted the population of the study. For the study, five SKSs were selected from each district randomly. From the area of operation of each SKS, ten member farmers who marketed their produce through SKS and five farmers who marketed their produce otherwise were selected randomly to constitute the sample of farmers. Similarly five traders selected from each SKS constituted the sample of traders. Data were collected from the sources through personal interview method by administering separate pre-tested structured schedules to farmers and traders. The data thus obtained were analysed by using bivariate tables, percentages, satisfaction indices, and ranking. Analysis of the socio-economic profile of the farmers revealed that older generation are more interested in farming than younger generation. The analysis also brought out the predominance of men in agriculture, and they possessed vast experience in farming. The results indicate that marginal and small holdings dominate the agricultural sector in the study area. Analysis of the annual income of the farmers showed that the number of farmers with an annual income of Rs.1,00,000 and above was higher among SKS farmers than Non-SKS farmers. The share of income from fruits and vegetables in the total agricultural income was higher for SKS farmers. ‘Better price for the produce’ followed by regular market for the produce, ‘better measurement and grading practices in the market’, ‘feeling of farmers own organisation’ were the most important reasons for farmers to take membership in SKS. Regarding the ownership pattern of cropped land of the farmers, the share of farmers cultivating on leased land was more among the SKS farmers than Non-SKS farmers. The SKS also attracted farmers with larger area under fruits and vegetables cultivation to its fold. The selected farmers depended more on man made sources of water than natural sources for irrigation and the majority of the farmers used either electric pump or diesel pump for irrigation. Majority of the SKS farmers preferred VFPCK as the main source of seeds for cowpea, bittergourd and amaranthus. In the case of nendran the most preferred source of suckers was traders. When the Non-SKS farmers preferred own sources and fellow farmers for the purpose. The main source of suckers of nendran was traders. Analysis of the different varieties of crops preferred by farmers revealed that in the case of nendran farmers in general preferred Mettupalayam, Kottayam and Manjeri varieties. In the case of cowpea Lola was the most preferred of SKS farmers and Non-SKS farmers preferred Lola, Local and Vyjayanthi varieties. Regarding bittergourd when SKS farmers showed a strong preference towards Preethi, Non-SKS farmers mostly preferred Local variety. Arun was the most preferred variety of amaranthus SKS farmers and Kannara Local by Non-SKS farmers. In the case of ivy gourd majority of SKS farmers preferred Sulabha variety while Non-SKS farmers preferred Local variety. The main sources of planting material for farmers were VFPCK, KAU, traders and fellow farmers. KAU was the only institutional agency which supplied all types of planting materials. Out of the four sources of planting materials, KAU was the dearest and VFPCK the cheapest. Majority of the SKS farmers availed credit from commercial banks linked to SKS when majority of the Non-SKS farmers preferred money lenders and traders for their credit needs. The SKS farmers harvested nendran coinciding with the SKS market days. Cowpea, bittergourd and ivy gourd were harvested thrice a week by majority of the SKS farmers. Vast majority of Non-SKS farmers harvested nendran weekly. Majority of the Non-SKS farmers harvested cowpea and amaranthus thrice in a week. In the case of bitter gourd and ivy gourd majority harvested two days in a week. SKS was the prime source of market information to SKS farmers while traders constituted the main source of information to Non-SKS farmers. The SKS farmers were better placed with regard to scientific marketing practices. All the produces except amaranthus and cowpea were graded and sold in SKS. Only nendran and bitter gourd were graded in Non-SKS market. Majority of the SKS farmers used plantation leaves for packing nendran. Plastic bags were used for packing other crops. Majority of the farmers in Non-SKS markets marketed nendran without packing. The main reason for selling the produce outside the SKS market was farm gate collection by the traders. The important means of transportation for SKS farmers was tailed autorikshaw and head load for majority of Non-SKS farmers. Price fluctuation was the only one risk perceived by SKS farmers, while the Non-SKS farmers perceived the risk of unsold produce, physical damage, and default in payment besides price fluctuation. In order to manage the price risk a majority of the SKS farmers sold the produce to the same trader even at a lower price when Non-SKS market sold to other traders. Regarding the realization of credit sales, 90 per cent of the SKS farmers received payment within a week while majority of the Non-SKS farmers received payment within two weeks. Lack of adequate processing and storage facilities were reported as the most serious problems faced by the commercial fruits and vegetables farmers. The SKS farmers were found better trained than Non-SKS farmers. While analyzing the structure of SKS market, it was found that majority of the sample traders were wholesalers.
