ThesisItem Open Access Seed quality assessment in natural and artificial aged seed of tomato and eggplant(CCSHAU, Hisar, 2023-01) Nisha; Bhuker, AxayThe seed of two important solanaceous crops tomato (Solanum lycopersicum L.) and eggplant (Solanum melongena L.) was procured from Department of Vegetable Science and study was conducted to assess the effect of natural and artificial ageing on seed quality parameters and their correlation and to find out the effect of priming and storage containers on seed quality at Department of Seed Science and Technology, CCS HAU Hisar during 2020-2022. Under natural and artificial ageing storage period most of the seed quality parameters showed decreasing trend as the storage period increased in both cloth and polythene bag. Cloth bag maintained the germination upto 12 months while polythene bag maintained germination up to 15 months above Indian Minimum Seed Certification Standards (>70%). The polythene bag maintained 60.67 & 64.00% germination while in cloth bag it was 55.67 & 60.00% after 18 months of storage under ambient conditions in tomato and eggplant seeds respectively. The other seed quality parameters i.e. seedling length, seedling dry weight, vigour indices, viability percentage, speed of emergence index, seedling establishment, DHA, SOD, CAT, POD were found superior in polythene bag as compare to cloth bag. The mean emergence time and fungus infection was observed less in polythene as compare to cloth bag.The germination percentage after 24 h (72.67, 74.00%) of artificial ageing were found at par with the values of germination after 12 months (73.67, 77.00%) of natural ageing in polythene bag for tomato and eggplant respectively. Seeds primed with GA3 @ 50 ppm can enhance 24.6 percent germination in tomato and 21.2% in eggplant over unprimed seed in 18 months old seed. GA3 @50 ppm is also effective in controlling fungal infection and enhancement of other seed quality parameters i.e. seedling length, seedling dry weight, seed vigour indices, viability percentage, catalase activity, peroxidase activity, dehydrogenase activity, superoxide dismutase activity, speed of emergence index and seedling establishment. It is concluded from the study that polythene bag is a suitable container and GA3@50ppm is suitable priming agent for tomato and eggplant seeds. Germination percentage after 12 months of natural storage can be estimated through accelerated ageing test for 24 hours in tomato and eggplant crop.ThesisItem Open Access Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)(CCSHAU, Hisar, 2023-07-20) Rohit; V.S. MorThe present studies entitled “Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)” were carried out at Laboratory and field of Department of seed science and technology, CCS HAU, Hisar. The seed treated with Azotobacter+Phosphate solubilizing bacteria enhanced the seed quality in terms of all parameters of fresh, one year old and two year old seed lot of oat and Chlorpyrifos and their combinations showed negative effect on seed quality. Among the three years seed lots, highest performance were observed in freshly harvested seeds for various seed quality parameters i.e radicle emergence (88.69%), speed of germination (54.33), standard germination (93.46%), seedling length (40.94 cm), seedling dry weight (12.37mg), vigour index-I (3,829.30), vigour index-II (1,156.93), field emergence index (9.75), seedling establishment (69.96%) and plant height (28.75cm) at 30 days whereas, the maximum enhancement in standard germination and vigour indices was observed in one year seed lot and the minimum was observed in fresh seed lot. The correlation study shows that the field emergence of oat had positive and significant correlation with germination percentage, seedling length and seedling dry weight. The seedling establishment was also found significantly correlated with vigour index-I, vigour index- II, field emergence and speed of germination. Similarly, field emergence index was significantly correlated with vigour index-I, seedling length, vigour index- II, seedling dry weight, germination percentage and non-significant with speed of germination. The seedling establishment of oat in the field was found to have significant positive correlation with most of the seed quality parameters such as germination percentage, seedling length and seedling dry weight but negative correlation with radicle emergence.ThesisItem Open Access Effect of seed treatment on seed quality of Quinoa (Chenopodium quinoa) during storage(CCSHAU, Hisar, 2023-07-20) Aman; Puneeth Raj M.S.The present study entitled ―Effect of seed treatments on seed quality of Quinoa (Chenopodium quinoa) during storage‖ was carried out at laboratory of Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar. The seeds of quinoa (Cv. Himshakti) were treated with imidacloprid, thiram, vitavax and polymer along with their combinations and were stored for 10 months. Secondly seeds were primed with water, cobalt chloride, potassium nitrate, calcium chloride and GA3 at 25℃ for 12 h, 24 h and 36 h after 10th month of storage period. All the treatments were evaluated for seed quality parameters viz. seed moisture content (%), speed of germination, germination (%), seedling length (cm), radicle emergence, seedling dry weight (mg), vigour index I & II. Results revealed that seeds treated with Imidacloprid + Vitavax (Thiram + Carboxin) + Polymer were found significantly higher in seed quality parameters followed by Vitavax (Thiram + Carboxin) + Polymer and least was found in control. Seeds stored in polythene bags showed better seed quality than seeds stored in cloth bags. Quinoa seeds primed with GA₃ at 25℃ for 24 h were found significantly higher seed quality parameters compared to other treatments.ThesisItem Open Access Maximization of seed yield and quality in cowpea {Vigna unguiculata (L.) Walp}(Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-11) Digamber; Jakhar, S. SSeed 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.ThesisItem Open Access Maximization of seed yield and quality in cowpea {Vigna unguiculata (L.)
