    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 sowing dates and cuttings on seed yield and quality in oat (Avena sativa L.)
    (CCSHAU, 2018) Digamber; Punia, R.C.
    Seed quality is a vital factor in the crop establishment and overall performance of the crop. Oat is used in India both as feed and fodder. 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 realizing 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 rabi 2016- 17. The variety of oat used was HJ-8. Three different sowings were done on 6th Nov, 2016; 2nd Dec, 2016 and 2nd Jan, 2017 in order to study the effects of sowing dates, days to foliage cut after sowing and stubble height from ground level on seed yield and quality. The date of sowing have significant effect on seed yield and quality of oat. The maximum seed yield (13.8 q/ha) with better seed quality was found in normal sown crop D1 (6th November) followed by (11.4 q/ha) late sown crop D2 (2nd December). Low seed yield (5 q/ha) along with poor seed quality was observed in very late sown crop D3 (2nd January). One foliage cut at 65 DAS (Normal Sowing) and 50 DAS (Late Sowing) can be taken for getting additional fodder yield without affecting the seed yield and quality to a much extent. The stubble height from ground level should be left approximately 10 cm for better regeneration for better seed yield and quality for seed production.
