    Maximization of seed yield and quality in cowpea {Vigna unguiculata (L.) Walp}
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-11) Digamber; Jakhar, S. S
    Seed quality is a vital factor in the crop establishment and overall performance of the crop. Cowpea is a crop which is used both as feed and fodder in India. The non-availability of quality seeds of improved varieties is a crucial factor in popularization of fodder crop. Availability of viable and vigorous seed at the planting time is important for achieving targets of agricultural production because good quality seeds act as a catalyst for exhausting the potential of other inputs. Keeping in view the seed quality, investigation was carried out in the laboratory and research farm of Department of Seed Science and Technology, Chaudhary Charan Singh Haryana Agricultural University, Hisar during year 2019 and 2021. The cowpea variety CS-88 was used for the experiment. The seeds were treated before sowing with three different fungicides i.e. captan, vitavax and bavistin. Three different sowings were done on 30thMarch, 30thMay and 30thJune in order to study the effects of sowing dates.Crop was sprayed with three different nutritional sprays at different growth phases i.e. NPK (18:18:18), NPK (17:44:0) - Urea phosphate and NPK (0:0:50) - SOP Sulphate of potash to study the effecton seed yield and quality. The dates of sowing, seed treatments and foliar sprays have significant effect on seed yield and quality of cowpea. The maximum seed yield (7.81& 7.71 q/ha) with better seed quality was found in 30thMay sown crop followed by (6.99& 6.81 q/ha) 30thMarch sown crop. Lowest seed yield (6.69& 6.63 q/ha) along with poor seed quality was obtained in 30thJune sown crop during the year 2019 and 2021 respectively.The seeds treated with captan provided the maximum (7.76 & 7.69 q/ha) seed yield. The crop can be sprayed with NPK (18:18:18)at vegetative stage to get the higher yield.

    Effect of Early Heat Stress on Wheat Genotypes
    (CCSHAU, Hisar, 2020-02) Sharma, Sushma; Punia, R. C
    The present investigation was carried out to study the effect of early heat stress on germination characters, plant growth and yield parameters along with the seed quality of progeny seeds in twelve wheat genotypes during the years 2016-2019. The seeds were germinated under four different temperatures viz. 20°C, 25°C, 30°C and 35°C and then their germination and the vigour potential was assessed after 8 days. In an another experiment, seeds of all genotypes were sown in trays containing sand, cocopeat and vermi-compost and kept in the germinators under above said temperatures continuously for 8 days. The seedlings were then transplanted in field at timely and late sown conditions and different plant growth and yield characters were recorded. The seeds obtained from these plants were further evaluated for seed quality. The results revealed that the highly significant mean squares confirmed the presence of substantial amount of variation and significant difference for all the factors involved in the study. Standard germination along with other vigour parameters were affected by different temperature treatments. Genotypic differences prevailed and the genotypes viz. WH 730, WH 1123, EC 277134 and HD 2967 maintained above 90% germination even at 35°C while PBW 725 and WH 1105 were unable to tolerate heat at the germination stage and their germination reduced drastically at higher temperatures. However, germination percentage at 20°C and 25°C was found statistically at par in all the genotypes. Other vigour parameters were maximized at 25°C. This study concluded that wheat sowing can be done at a mean temperature of around 25°C, this could be a strategy to escape the terminal heat stress by providing the crop a little more time to mature. The catalase and SOD enzymes activities continuously increased with temperature and CAT was found maximum at 35°C and SOD was maximized at 30°C, then it decreased at 35°C. In the second experiment, results revealed that plant height and tillers per plant were highest at 20°C and reduced at higher temperatures. The spike parameters increased with temperature and found highest at 35°C treatment and lowest at 20°C. The overall best performance was shown by the plants germinated at 25°C under both timely sown and late sown environments. The highest grain yield was recorded in the genotype WH 1105 under normal conditions while overall mean highest yield through all the temperatures was obtained in the genotype EC 277134. For all the characters studied, timely sown condition was found better than late sown conditions. Seeds obtained from 20°C treated plants were found best for most of the seed quality parameters. However, standard germination, root length and vigour index-II had maximum values at 25°C treatment. Seeds obtained from 35°C treatment had higher membrane integrity as shown by their lowest electrical conductivity. Treatment of heat under late sown conditions has shown thermo-priming effect and enhanced the standard germination and speed of germination of progeny seeds.

    (CCSHAU, Hisar, 2020-02) Ravinder Kumar; Sangwan, V.P.S
    The present investigation was carried out at Research Farm and in the Laboratories of the Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar, Haryana during 2017-18 and 2018-19 to access the effect of micronutrients on seed yield, quality and storability in coriander. The field experiment was carried out in randomized block design with four replications. The experiment consisted of soil and foliar application of micronutrients i.e., (T1) RDF as control, (T2) RDF+ Ferrous sulphate 5 Kg/ha (Soil application), (T3) RDF+ Ferrous sulphate 7.5 Kg/ha (Soil application), (T4) RDF+ Ferrous sulphate 10 Kg/ha (Soil application), (T5) RDF+ Zinc sulphate 3 Kg/ha (Soil application), (T6) RDF+ Zinc sulphate 4 Kg/ha (Soil application), (T7) RDF+ Zinc sulphate 5 Kg/ha (Soil application), (T8) RDF+ Boric acid 2 Kg/ha (Soil application), (T9) RDF+ Boric acid 3 Kg/ha (Soil application), (T10) RDF+ Boric acid 4 Kg/ha (Soil application), (T11) RDF+ water spray, (T12) RDF+ Ferrous sulphate 0.4 % (foliar spray), (T13) RDF+ Ferrous sulphate 0.5 % (foliar spray), (T14) RDF+ Ferrous sulphate 0.6 % (foliar spray), (T15) RDF+ Zinc sulphate 0.4 % (foliar spray), (T16) RDF+ Zinc sulphate 0.5 % (foliar spray), (T17) RDF+ Zinc sulphate 0.6 % (foliar spray), (T18) RDF+ Boric acid 0.2 % (foliar spray), (T19) RDF+ Boric acid 0.3 % (foliar spray), (T20) RDF+ Boric acid 0.4 % (foliar spray). Foliar applications of micronutrients were done at 45 and 90 DAS. Results showed that, seed yield was increased significantly (16.59 and 17.27 q/ha during 2017-18 and 2018-19 respectively) when the crop received soil application with 5 kg zinc sulphate/ha (T7) over control. Application of micronutrients showed positive effect for all the growth, yield and yield attributes viz, days to 50 % flowering, days to maturity, fresh weight per plant (60, 105 DAS and at harvest), dry weight per plant (60, 105 DAS and at harvest) number of branches per plant, plant height at harvest (cm), number of umbels per plant, number of umbellets per umbel, number of seeds per umbellets, number of seeds per umbel, seed yield per hectare (q), biological yield per hectare (q) and harvest index (%). Soil application with 5 kg zinc sulphate/ha (T7) recorded significantly maximum standard germination (%), seedling length (cm), seedling dry weight (mg), vigour index – I & II, enzyme activity, speed of germination and seedling establishment. From the storage studies, it was concluded that all the seed quality parameters were decreased after 18 months of storage.

    Studies on effect of picking stages, seed treatments and containers on seed quality of okra (Abelmoschus esculentus L. Moench)
    (CCSHAU, Hisar, 2020) Malik, Sunil Kumar; Jakhar, S.S.
    The present study was carried out in the field and laboratories of Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar, Haryana during 2018-2020 to study the effect of picking stages, seed treatments and containers on seed viability of okra (Abelmoschus esculentus L. Moench). The best picking stage of okra for quality seed production was found on the fruits developed on middle nodes (6th to 10th) as compare to lower (1st to 5th) and upper nodes (11th to 15th). The seeds obtained from middle nodes were used for further studies. To study the effect of seed treatment with different fungicides and botanicals, seven fungicides (carbendazim, tebuconazole, difeconazole, flusilazole, chlorothalonil, azoxystrobin and vitavax power) and three botanicals (Pongamia, neem and turmeric) were used. The treated seeds were kept in three different containers viz., Polythene bag, hermetic bag and metal box up to 18 months at ambient room conditions. Among the interaction effects of fungicide with containers, the seed treatment with azoxystrobin stored in metal box was found superior. While the interaction effect of botanicals with containers, the seed treatment with neem leaf powder stored in metal box was found best. During the entire period of this study, it was revealed that the germination was maintained above Indian Minimum Seed Certification Standards (>65%). All the seed quality parameters (germination, shoot and root length, seedling dry weight, vigour indices-I & II, catalase, superoxidase dismustase, dehydrogenase and peroxidase) were declined with the advancement of storage time except electrical conductivity. The present study also indicated that the fungicide treated seeds showed better performance than botanical treated seeds
