ThesisItem Open Access DIAGNOSTIC AND THERAPEUTIC STUDIES ON INTESTINAL OBSTRUCTION IN CALVES(Palampur, 2006-04-25) KUMAR, ADARSH; Kanwar, M.S.ThesisItem Open Access INTEGRATED MANAGEMENT OF BACTERIAL WILT OF TOMATO(Palampur, 2004-05-28) AGGARWAL, PREETI; Sood, A.K.ThesisItem Open Access EFFECT OF DIFFERENT SOURCES OF SULPHUR ON YIELD, QUALITY OF CAULIFLOWER AND SULPHUR FRACTIONS IN AN ACID ALFISOL(CSKHPKV Palampur, 2016-07) NEHA; Sharma, Sanjay KA field experiment was conducted during rabi 2014-15 on cauliflower (Brassica oleracea L. var. Palam Uphar) at the experimental farm of Department of Soil Science, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. The experiment consisted of three levels (12.5, 25, 37.5 kg S ha-1) and four sources (Sartaj natural gypsum, locally available gypsum, elemental sulphur and single super phosphate) of sulphur along with one control in a randomized block design. The application of sulphur @ 37.5 kg S ha-1 influenced growth parameters, yield attributes, quality, harvest index and per cent marketable curds significantly over 12.5 kg S ha-1. Likewise, highest net curd yield (113 q ha-1) was recorded with the application of 37.5 kg S ha-1, which was however, statistically at par with that obtained with the application of 25 kg S ha-1 (105.2 q ha-1) but significantly superior to that obtained with the application of 12.5 kg S ha-1 (89.5 q ha-1). Control recorded the lowest net curd yield (77.8 q ha-1). Among sources, Sartaj gypsum recorded maximum value of all these parameters followed by single super phosphate, locally available gypsum and elemental sulphur. Likewise, Sartaj gypsum recorded highest net curd yield (114.2 q ha-1) which was however, statistically at par with single super phosphate (102.9 q ha-1). The uptake of N, P, K, S, Fe, Mn, Cu and Zn by cauliflower increased with increased level of sulphur and followed the yield trend. Among sources, Sartaj gypsum recorded maximum nutrient uptake by cauliflower followed by single super phosphate. The different levels and sources of sulphur did not show any significant effect on soil pH, organic carbon, available K, Fe, Mn, Cu and Zn but had a significant effect on soil available N and P content. In case of fractions, available, water soluble, organic and total sulphur increased significantly with increased levels of sulphur. Sartaj gypsum recorded maximum value of available sulphur (12.4) and water soluble (9.8) followed by single super phosphate, locally available gypsum and elemental sulphur. Different sources of sulphur did not show any significant effect on heat soluble sulphur, organic sulphur and total sulphur. All sulphur fractions were significantly and positively correlated with yield, quality of cauliflower and sulphur fractions. However, higher correlation values were observed with water soluble and available sulphur and least with heat soluble sulphur. Maximum gross returns, net returns per hectare and gross returns per rupee invested were found when sulphur was applied @ 37.5 kg S ha-1 (Rs. 113083, 62286, 2.23, respectively) which was significantly superior to 12.5 kg S ha-1 (Rs. 89417, 40921, 1.84, respectively) but at par with 25 kg S ha-1(Rs. 105333, 55688, 2.13, respectively).ThesisItem Open Access GENE ACTION FOR YIELD AND RELATED TRAITS IN SOYBEAN [Glycine max (L.) Merrill] AND DEVELOPMENT OF INTERSPECIFIC HYBRIDS INVOLVING WILD SPECIES(CSKHPKV Palampur, 2014-12) INDU BALA; Jai DevThe present investigation entitled “Gene action for yield and related traits in soybean [Glycine max (L.) Merrill] and development of interspecific hybrids involving wild species” was carried out at the Experimental Farm of the Department of Crop Improvement, CSK HPKV, Palampur to gather information on genetic architecture for seed yield and component traits in soybean and to introgress desirable genes from wild species to cultivated ones. The experimental material comprised of 54 triple test cross progenies derived by mating 18 lines with three testers, namely, Hara Soya (L1), Him Soya (L2) and their F1 (L3). This genetic material was evaluated in a randomized complete block design with three replications during kharif 2013. Epistasis was found to be an integral part of genetic variation for majority of the traits. Epistatic interaction for many traits was ‘j+l’ type except days to 50% flowering, days to 75% maturity, reproductive phase, petiole length, seed per pod, harvest index and 100 seed weight, whereas plant height, internode length, pods per plant and biological yield per plant carried ‘i’ type epistasis alongwith ‘j+l’ type. Additive component (D) was more pronounced than dominance component (H) for most of the traits. Both additive and dominance components were of almost equal magnitude for pod length indicating the importance of both additive and dominance type of gene action, whereas partial degree of dominance was noticed for majority of traits. The kind of genetic variance revealed from triple test cross can be exploited by intermating selected individuals in early segregating generations with delayed selection in later generations, diallel selective mating/ biparental mating or recurrent selection followed by pedigree method to exploit both additive and non-additive components alongwith epistasis. Lines Bragg, Shivalik and P9-2-2 were found to be good general combiners for most of the traits. The cross combinations, Bragg x Hara Soya, PK- 472 x Him Soya, DS-1213 x Hara Soya, H-330 x Hara Soya and H-330 x Him soya showed high per se performance, SCA effects, heterobeltiosis and economic heterosis for seed yield per plant and were rated as potential crosses for further improvement. Cross H-330 x Him Soya showed resistance against brown spot and bacterial pustule diseases. The interspecific hybrids developed involving Glycine max x G. soja, were true to type based on confirmation at the morphological, molecular and cytological level. Sufficient variability was found for all the traits studied in wide hybrids. Seed yield per plant showed significantly positive correlation with reproductive phase, pods per plant, pod length, petiole length, harvest index and 100-seed weight.ThesisItem Open Access EVALUATION OF PRESCRIPTION BASED FERTILIZER RECOMMENDATIONS IN SYSTEM OF RICE INTENSIFICATION (SRI) IN WET TEMPERATE ZONE OF HIMACHAL PRADESH(CSHHPKV Palampur, 2016-07-05) MITTAL, SHREYANSH; Sharma, Sanjay K.A field experiment was conducted during kharif 2015 at the Experimental Farm of Department of Soil Science, CSK HPKV, Palampur to study the effect of different approaches of fertilizer application on growth parameters and productivity; soil physico-chemical properties; nutrients uptake and economics of rice under SRI. There were eight treatments (control, farmers‟ practice, general recommended dose, soil test based, yield targets 3.5, 4.0, 4.5 and 5.0 t ha-1 replicated thrice in a randomized block design (RBD). The soil of experimental field was silty clay loam in texture, acidic in reaction ( pH 5.5), high in organic carbon (11.2 g kg-1 ), medium in available N (320 kg ha-1 ), high in available P (30 kg ha-1 ), low in available K (112 kg ha-1 ) and sufficient in micronutrients. Soil samples (0-0.15 m) were collected before sowing, at 50% flowering and at harvest for chemical analysis. Plant samples were collected at 50% flowering and harvest and analyzed for N, P, K contents whereas, micronutrients (Fe, Mn, Zn and Cu) concentration in grain and straw at harvest was also determined after harvest of crop. Growth parameters and yield attributes were also recorded at specified intervals. All the levels for prescription based fertilizer application gave significantly higher grain and straw yield as compared to other approaches of fertilizer application barring few exceptions. Further, treatment for yield target of 5.0 t ha-1 resulted in maximum growth (plant height, total number of effective tillers, panicle length, 1000 grain weight, spikelet fertility percentage, number of grains per panicle), grain (4.46 t ha-1 ) and straw (10.03 t ha-1 ) yield. Targeted yield treatments significantly increased the nutrients uptake over other approaches of fertilizer application. The status of N, P and K was higher in STCR based fertilizer treatments at 50% flowering as well as at harvest of the crop. The STCR based fertilizer application treatments excelled all other approaches of fertilizer application in terms of net returns and benefit cost ratio. However, STCR approach for transplanted rice worked satisfactorily up to yield target of 4.0 t ha-1 beyond which deviation in yield from targeted yield was more than 10 per cent. Soil test based and general recommended dose of fertilizers recorded better plant growth and yield, and increased the nutrients uptake and N, P and K status in soil as compared to the farmers‟ practice and control.ThesisItem Open Access NITROGEN DYNAMICS AS INFLUENCED BY LONGTERM EFFECT OF PRESCRIPTION BASED FERTILIZER APPLICATION IN AN ACID ALFISOL(CSHHPKV Palampur, 2014-07-07) SHABNAM; Sharma, Sanjay K.The present investigation was carried out in the ongoing long-term experiment on soil test crop response correlation studies (STCR) initiated during kharif, 2007 at the experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur in randomized block design with eight treatments comprising control, farmers’ practice, general fertilizer dose, conventional soil test based fertilizer application and fertilizer application based on STCR approach with and without FYM for yield targets of 30 and 40 q ha-1 . The soil of the experimental site was Typic Hapludalf, silty clay loam in texture, acidic in reaction, medium in organic carbon, low in available N, high in P and medium in K at the initiation of the experiment. Soil samples (0-0.15m) taken after the harvest of maize (kharif, 2013) were analyzed for different forms of nitrogen and pH, OC, CEC, microbial biomass carbon and available N, P and K. Grain and stover yields of maize were recorded and uptake of various nutrients by maize was also worked out after the plant analysis. Continuous application of chemical fertilizers either alone or in combination with FYM enhanced the contents of different organic and inorganic nitrogen fractions. However, prescription based fertilizer application involving conjunctive use of fertilizers and FYM for yield targets of 30 and 40 q ha-1 proved superior to general fertilizer recommendation as well as conventional soil test based fertilizer application in influencing various forms of nitrogen. Likewise, highest contents of OC (8.3 g kg-1 ), CEC (13.4 c mol (p+ ) kg-1 ), microbial biomass carbon (119.5 mg kg-1 ), available N (282 kg ha-1 ), P (61 kg ha-1 ) and K (279 kg ha-1 ) were found under STCR (IPNS) based treatment for target yield of 40 q ha-1 which ultimately, resulted in the highest productivity of maize (37.6 q ha-1 ). In general, the contribution of different organic as well as inorganic forms of nitrogen viz., hydrolysable ammonical-N, amino acid-N, serine+threonine-N, hexosamine-N, unidentified-N, non hydrolysable-N, ammonical-N and nitrate-N, towards the total-N was 24.3, 24.4, 5.4, 7, 23, 6.4, 5.5 and 3.6 percent, respectively. Continuous cropping without fertilization resulted in depletion in hydrolysable ammonical-N, amino acid-N, serine+threonine-N, hexoseamine-N, unidentified-N and non-hydrolysable-N to the extent of 24, 17, 23, 3.6, 12 and 8 per cent, respectively. Hydrolysable ammonical-N exhibited highest correlation with available N (r=0.882) and accounted for 78 percent variation in available N. Hydrolysable ammonical-N recorded highest correlation with grain yield (r=0.898) and accounted for about 88 per cent of the variation, whereas, amino acid-N showed the highest correlation with stover yield (r=0.902) and accounted for about 81 per cent of the variation. Different fractions of nitrogen were found to be positively and significantly correlated with one another except non hydrolysable-N.ThesisItem Open Access INFLUENCE OF ZINC AND BORON ON WHEAT PRODUCTIVITY AND POTASSIUM USE EFFICIENCY IN AN ACID ALFISOL(CSHHPKV Palampur, 2012-12-01) NEHA; Sharma, R.P.The present investigation was carried out at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur with sixteen treatments consisting of four levels of K (0, 50,100 and150% of recommended dose), two levels of Zn (0 and 10 kg ha-1 ) and two levels of B (0 and 1 kg ha-1 ) in factorial randomized block design. Application of K @ 50, 100 and 150 per cent of recommended dose increased plant height, dry matter accumulation, total and effective tillers per metre row length, grains per ear and test weight significantly. Similarly, application of Zn (10 kg ha-1 ) and B(1 kg ha-1 ) influenced these growth and yield attributes of wheat significantly. Highest grain (42.52q ha-1 ) and straw (66.80q ha-1 ) yield of wheat was recorded under 150 per cent of recommended dose of K. Application of 150 percent of recommended dose of K increased grain and straw yield by 43.7 and 46.9 per cent over no K, respectively. Application of Zn (10 kg ha-1 ) increased grain and straw yield by 10.9 and 9.8 per cent over no Zn, respectively. The increase in grain and straw yield with the application of B (1 kg ha-1 ) was 5.6 and 6.3 per cent, respectively. Application of K increased N, P, K, Mn, Fe, Cu and B contents significantly at maximum tillering and harvesting. Application of Zn increased Zn and B contents significantly at both the stages but the contents of Fe, Mn and Cu decreased. However, B increased the contents of Zn and B only at maximum tillering stage and Zn, Mn and B at harvesting (grain and straw). Almost similar effects of K, Zn and B application on total nutrient uptake were observed. Application of Zn increased partial factor productivity, physiological efficiency, agronomic efficiency and apparent recovery. B application increased partial factor productivity and apparent recovery only. Application of K, Zn and B increased available K, DTPA extractable Zn and available B content significantly, respectively.ThesisItem Open Access Evaluation of multi-nutrient extractants for determination of available P, K and micronutrient cations for soil analysis in Himachal Pradesh(CSHHPKV Palampur, 2015-08-14) SHARMA, ANKITA; Sharma, Sanjay KMulti-nutrient extractants offer alternative for conventional methods as more nutrients can be extracted in one go. However, the suitability and accuracy of such extractants for the determination of available nutrients must be verified. Therefore, sixty soil samples (0-0.15 m depth) collected randomly from different districts of Himachal Pradesh were used to evaluate the efficiency of AB-DTPA and AAAc-EDTA in comparison to their standard methods for P, K and micronutrient cations. Soil pH (1:2.5), EC (µS cm-1 ), OC (g kg-1 ), textural class, and CEC (cmol (p+ ) kg-1 ) soil under study ranged from 5.67-7.56, 61-695, 2.8-27.7, sandy loam to clay loam and 4.1- 15.0, respectively. Available P (kg ha-1 ) extracted by four methods viz., Olsen P, Bray P1, AB-DTPA P and AAAc-EDTA P varied from 7.8-44.3, 9.5-61.1, 6.5-38.8, 10.5- 52.1; available K (kg ha-1 ) extracted by three methods viz., NH4OAc, AB-DTPA and AAAc-EDTA ranged from 103.6-372.3, 86.6-364.9 and 74.6-362.5. Likewise, DTPA, AB-DTPA and AAAc-EDTA extractable contents of Cu, Fe, Zn and Mn ranged from 0.3-5.8, 1.0-6.3 and 1.2-5.0; 3.9-42.2, 8.1-58.8 and 7.3-32.7; 0.2-6.6, 0.3-6.7 and 3.3- 26.2, 5.1-27.2 and 7.7-38.3, respectively. Bray P1 method of phosphorus determination extracted more amount of available P followed by AAAc-EDTA, Olsen and AB-DTPA methods. Likewise NH4OAc extracted more K followed by AB-DTPA and AAAc-EDTA. In case of micronutrients cations, AB-DTPA in general, extracted more amounts as compared to DTPA alone. Overall, phosphorus showed highly significant correlations with physico-chemical properties. Among methods of extraction for P, AAAc-EDTA showed higher correlation with the standard method (Olsen P) of determination. Available K contents determined by AB-DTPA and AAAc-EDTA were well correlated with standard method (NH4OAc) however; AAAc-EDTA had higher correlation with AB-DTPA method for K extractability. In case of micronutrients, all the methods correlated positively and significantly with each other Highest significant correlations were observed between AB-DTPA and DTPA for Cu, Fe and Zn. However, in case of Mn, the highest correlation was observed between AB-DTPA and AAAc-EDTA. Both, AB-DTPA and AAAc-EDTA methods were more economical compared to the conventional methods.ThesisItem Open Access STUDIES ON PEA ROOT ROT/WILT COMPLEX DISEASE.(CSK HPKV, Palampur., 2016) Nisha, Kumari; Thakur, B.R.The present investigations entitled “Studies on pea root rot/wilt complex disease” had been undertaken in the Department of Plant Pathology, College of Agriculture, CSK HPKV, Palampur during 2014-2016. Pea root rot /wilt complex had been noticed as an emerging problem in different agro climatic zones of pea growing regions of Himachal Pradesh. The disease has been observed with different intensity levels in different pea growing areas of the state. In Zone IV, the highest disease incidence of 54.7 % was recorded at HAREC, Kukumseri whereas, in Zone III, the disease incidence remained in moderate form i.e. 19.7%. However, in Zone II, highest disease incidence of 35.3% was recorded at Palampur. The two species of Fusarium viz., F. solani f. sp. pisi and F. oxysporum f. sp. pisi were found associated with pea root rot/wilt complex in the state. Both species produced distinct symptoms when inoculated on pea seedlings in test tubes containing Hoagland's solution. F. solani f. sp. pisi was solely responsible to cause root rots of pea resulting in yellowing of leaves from basal leaf to upward whereas, F. oxysporum f. sp. pisi was responsible to cause wilting without root rots by clogging of xylem vessels. For disease management different components viz., composts, bioagents, botanicals, chemicals and germplasm were evaluated in vitro to frame the management strategies. Vermicompost showed the maximum mycelial inhibition of 39.7% against F. oxysporum f. sp. pisi and 36.3% against F. solani f. sp. pisi followed by Farm Yard Manure with 29.7 and 30.0%, respectively. SMA-5 strain of Trichoderma harzianum showed the maximum mycelial inhibition of 77.4 and 75.9 % against F. oxysporum f. sp. pisi and F. solani f. sp. pisi respectively. The plant extracts of test botanicals proved to be effective against both the pathogens at 25% concentration resulting in >60% inhibition of mycelial growth. However, Eupatorium adenophorum showed maximum inhibition of 83.8 % against F. oxysporum f. sp. pisi and 77.5% against F. solani f. sp. pisi followed by Eucalyptus sp. resulting 83.1 and 76.1% inhibition respectively. All the test fungicides were found effective even at 50 ppm with >70 % inhibition of mycelial growth against F. oxysporum f. sp. pisi except Vitavax (carboxin 75 WP). Vitavax power (carboxin 37.5% + thiram 37.5%) and Bavistin (carbendazim 50 WP) gave cent per cent mycelial inhibition even at 500 ppm followed by Tilt (propiconazole 25 EC) and Raxil (tebuconazole 2 DS) with 93.3 and 90.4 % respectively. In case of F. solani f. sp. pisi, Bavistin (carbendazim 50 WP), Raxil (tebuconazole 2 DS) and Vitavax power (carboxin 37.5% + thiram 37.5%) yielded cent per cent mycelial inhibition at 1000 ppm. Out of one hundred thirteen elite pea lines, five pea genotypes viz, EC-329570, EC-329573, DPP-127-R, DPP-100, KS-268 were remained resistant against pea root rot complex. Management module comprised of soil amendment with Vermicompost : FYM (1:1) @ 15 t/ha carrying Trichoderma @ 2.5 kg/t and seed treatment with E. adenophorum @ 5.0 ml/kg seed was found most effective in the management of pea root rot /wilt complex pathogens giving maximum increase in yield i.e. 80.7 % as compare to control.
