    (CCSHAU, Hisar, 2021-09) Sunil Kumar; Kuldeep Kumar
    The experiment entitled “Evaluation of okra cultivars for growth, yield and quality under different dates of sowing” was conducted at Vegetable Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar, during the rainy season 2020-21 with five different dates of sowing S1 (15th June), S2 (30th June), S3 (15th July), S4 (30th July) and S5 (14th August) and three varieties V1 (Varsha Uphar), V2 (Hisar Naveen) and V3 (Hisar Unnat). Maximum plant stand after 15 days, plant height, number of fruit pickings, fruit length, number of fruits per plant, average fruit weight, fruit yield per plant, yield, dry matter, ash content, acidity and B:C ratio were recorded from 15th July date of sowing in the cultivar Hisar Naveen. However, minimum number of days to 50% flowering and days to first fruit picking were recorded from 14th August date of sowing in the cultivar Hisar Naveen. Maximum number of branches, internodal length, crop duration, incidence of YVMV and severity of disease were recorded minimum from 15th June date of sowing in the cultivar Hisar Naveen. Based on the study, it was found that higher fruit yield with better quality of fruits and minimum incidence of disease was obtained from Hisar Naveen sown on 15th July which was statistically at par with 30th July date of sowing under prevailing Haryana climatic conditions.

    Evaluation of tomato genotypes for growth, yield, quality and root-knot nematode resistance
    (CCSHAU, Hisar, 2021-08) Singh, Sandeep; Arora, Indu
    An experiment on “Evaluation of tomato genotypes for growth, yield, quality and root-knot nematode resistance” was conducted on cherry and non-cherry tomato genotypes in the screenhouse of Department of Nematology and Vegetable Research Farm, Hisar. In cherry type tomato genotypes, Pusa Cherry No. 214 had maximum fruit length(cm), fruit girth(cm), weight of fruits per plant per plant(kg), total yield, and marketable yield (3.01 cm,2.91 cm, 4.08 kg, 485.33 q/ha, 446.11 q/ha, respectively) while in non-cherry tomato genotypes Arka Rakshak had maximum fruit length (cm), fruit girth (cm), weight of fruits per plant (kg), total yield and marketable yield (5.19cm, 4.69 cm, 3.08 kg, 366.64 q/ha, 334.68 q/ha). TSS was found maximum in TW4 (7.53 0B) and ascorbic acid content in Punjab Rood cherry (38.04mg/100g) in cherry tomato genotypes while Punjab Garud with maximum TSS and ascorbic acid content (6.470B and 11.96 mg/100g, respectively) had shown superior fruit quality in non-cherry tomato genotypes. Among the different cherry tomato genotypes, TF-1 had the lowest number of galls per plant, number of egg masses per root system and was found resistant with root-knot index of 2.00 while among the non-cherry tomato genotypes NT-8(Hisar Lalit) was found moderately resistant with root-knot index of 3.00. Therefore, it is concluded in the present study that among the screened tomato genotypes, TF-1 (cherry type, resistant) and NT-8 (non-cherry type, moderately resistant) can be grown as resistant cultivars or can be used as rootstocks for grafting in tomato for growing under nematode infested fields/polyhouse while Pusa Cherry No. 214 (cherry type tomato genotype) and Arka Rakshak ( non-cherry type tomato genotype) gave higher yield ( 485.33 q/ha and 366.64 q/ha, respectively) in comparison to other genotypes under field conditions in Haryana.

    Quality analysis of naturally and artificially aged seeds of Kasuri Methi (Trigonella corniculata L.)
    (CCSHAU, Hisar, 2021-08) B. R, Chandana; Tehlan, S K
    Seed is the basic input of any cultivation system and its quality significantly contributes for better yielding of the crop. The present investigation was carried out during 2019-20 on seven genotypes of Kasuri methi (Trigonella corniculata L.) viz., KM 139-1, HM 538, HM 557, GC 208, GC 209, Kasuri Selection and KM Hosiyarpur. Four seed lots were used under natural ageing viz. freshly harvested seed lot, one year, two year and three years ambient stored seeds. For artificial ageing, freshly harvested seed lot was accelerated aged at 40±10C temperature and 100% relative humidity for 48, 72 and 96 hours. All the fenugreek genotypes were taken to evaluate the seed viability/vigour parameters, to determine the inter-relationship among various seed quality parameters and to determine correlation among natural and artificial ageing. All the seed lots were subjected to vigour and viability test with three replications and observation were recorded on standard germination, seedling length, seedling fresh weight, seedling dry weight, vigour index I &II, electrical conductivity, dehydrogenase activity, catalase activity, peroxidase activity, tetrazolium test, pH of seed leachates and field emergence. The results of the study indicates that, all the seed quality parameters reduced with increase in ageing period in both natural and artificial ageing except for electrical conductivity which increased with advancement in ageing period. Decrease in values of all the seed quality parameters and increase in electrical conductivity values with advancement of ageing represent decrease in vigour and viability of seed lots. A reduction of 21.8% in germination was observed after three years of natural ageing. Genotype K Selection and HM 557 were found to be more vigorous and genotype K M Hosiyarpur was found to be least vigorous and evaluated to be a poor storer. The standard germination, seed vigour index I & II, tetrazolium test, pH of seed leachates, and enzyme activity (Dehydrogenase, catalase and peroxidase activity) emerged as reliable predictors of seed quality and field emergence. Correlation studies revealed that all the seed quality parameters were positively associated among themselves. Electrical conductivity showed negative association with all seed quality parameters. Values observed from 48 hours artificially aged seed reported results equivalent to three years naturally aged seeds. Assessment of seed lot at 48 hours of artificial ageing can be used to determine seed lot field performance after storage.

    This is to certify that this thesis entitled Evaluation of intercrop and their pattern in onion seed crop
    (CCSHAU, Hisar, 2021-07) Nitesh Kumar; Dhankhar, Surender Kumar
    The present investigation entitled “Evaluation of intercrop and their pattern in onion seed crop” was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during season of 2018-19. The experimental treatments viz., T1-onion seed crop (sole ) 60 X 60 cm , T2-palak (sole) 15 X 5cm, T3-methi (sole) 20 X 10 cm , T4-onion + palak (one row) T5- onion + palak (two rows), T6- onion + palak (three rows), T7- onion + palak (broadcasting), T8- onion + methi (one row), T9- onion + methi (two rows) and T10- onion + methi (broadcasting) were laid out in a Randomized Block Design (RBD) with three replications. Based on the research investigation it was found that the Plant height, number of seed stalks bulb-1, length and diameter of flower stalks, number and weight of seeds umbel-1 and plant-1 were significantly higher in sole crop of onion than rest of the treatments. Sole crop of onion at spacing 60 X60 cm provided the maximum yield of seed per unit area. The leaf yield of palak was significantly higher with palak sole crop than intercropping treatments due to minimum competition between the plants for space and nutrients. Maximum net return (Rs 548175/ha) and B:C ratio (5.18) was recorded for onion+ palak (one row) after that treatment of onion+ methi (one row) gave a following net return of Rs. 544247/ha and B: C ratio of 5..16 Also onion + palak (one row) intercropping system gave highest onion seed equivalent yield (OEY) i.e.6.54 q/ha. It has been concluded that onion intercropped with palak (one row )could be more remunerative for earning maximum net returns than the onion sole crop.

    Combining ability and heterosis studies for morphological and fruit yield traits in okra [Abelmoschus esculentus (L.) Moench]
    (CCSHAU, Hisar, 2021-09) Yadav, Kalpana; Dhankhar, S.K.
    The present investigation entitled ―Combining ability and heterosis studies for morphological and fruit yield traits in okra [Abelmoschus esculentus (L.) Moench]‖ was carried out at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during spring-summer and rainy season of 2020 using line x tester mating design with a view to study the extent of heterosis, GCA and SCA effects in advance inbred lines of okra and to find out correlation and path coefficients for fruit yield and its attributes. The experimental material comprised of fourteen genetically diverse genotypes of okra involving twelve lines and two testers (Hisar Naveen and Hisar Unnat) and standard check HBH-142. These lines and testers were crossed using line x tester mating design during spring-summer season of 2020, to produce twenty-four F1 crosses. Analysis of variance for different quantitative characters studied during the experimentation indicated highly significant differences among the parents, crosses and commercial check at 5% and 1% level of significance. In terms of yield per hectare, four crosses viz. HB-20-3-4 x H.N, HM-1 x H.U, HBMS-1 x H.U and HB-76-2-4 x H.N showed significant positive economic heterosis over the standard check HBH-142 for yield and its contributing characters. Two lines viz., HB-20-3-4 and HM-1 showed significant positive GCA effect for yield per hectare and parents HB-20-3-4 also registered positive GCA effects for fruit length, length of peduncle, average fruit weight and number of fruits per plant. The cross HB-60-1 x H.N followed by HBMS-1 x H.U, HB-20-3-4 x H.N, HM-1 x H.U and HB-96-2 x H.U demonstrated strong SCA effects for yield and its contributing features. The ratio of general combining ability variances (σ2GCA) and specific combining ability variances (σ2SCA) was less than unity for all the seventeen quantitative traits indicated the non-additive gene effects predominated in determining the expression of all these characters and also demonstrates variability in genotypes which provide ample scope for improvement of yield and its contributing traits in okra.

    Studies on the effect of manure and biofertilizers on seed production of carrot (Daucus carota var. atrorubens)
    (CCSHAU, Hisar, 2021-07) Monika; Makhan Lal
    Carrot (Daucus carota var. atrorubens) belonging to family Umbelliferae with chromosome number 2n=18 is a popular cool season vegetable and is one of the important root vegetable crops. The inflorescence, typical of the Umbelliferae, is a compound umbel. In India, root to seed is the standard method used for the production of high quality seed as this method allows the selection of healthy and true to type roots for the planting of stecklings. Organic seed production includes growing of seed crops by a collection of guidelines that prohibit the use of synthetic products/ chemicals. The present study was conducted at Seed Research Area of Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar during spring-summer season of 2018-19. The objectives of the investigation were to study the effect of manure and biofertilizers on growth, seed yield and quality parameters of carrot seed crop. The experiment involved fourteen treatments, viz., T1- Absolute control, T2- RDF (N:P:K 80:40:40 kg/ha), T3- Farm yard manure 25t/ha, T4- Poultry manure 4t/ha, T5- Vermicompost 8t/ha, T6- FYM 12.5t/ha+ PM 2t/ha, T7- FYM 12.5t/ha+ PM 2t/ha, T8- FYM 12.5t/ha+ PM 2t/ha+ VC 4t/ha, T9- FYM 12.5t/ha+ PM 2t/ha+ Azo+PSB, T10-FYM 12.5t/ha+ Azo+PSB, T11- FYM 12.5t/ha+ VC 4t/ha+ Azo+PSB, T12- VC 8t/ha+ Azo+PSB, T13- PM 4t/ha+ Azo+PSB and T14- FYM 12.5t/ha+ PM 2t/ha+ VC 4t/ha + Azo+PSB and was laid out in Randomized Block Design with three replications. Highest plant growth, seed yield and yield attributing characters viz., number of umblets per umbel, number of seeds per umblets, number of seeds per umbel etc. and quality of seeds in terms of test weight, germination %, vigour index-I and II and Accelerating ageing test of 48 hours (germination %) during storage period of 3 and 6 months of carrot cv. Hisar Gairic was obtained with treatment T14 having combination of all the three manure and biofertilizers (FYM 12.5t/ha+ PM 2t/ha+ VC 4t/ha+ Azo+PSB), which was found at par with treatments T8, T9, T11 and T2. However, the B:C ratio was obtained highest with the treatment T9.
