The present investigation entitled “Curd Cutting Techniques and Micronutrients Application on Seed Yield and Quality of Cauliflower (Brassica oleracea var. botrytis L.)” was conducted at vegetable seed production farm, Department of Horticulture (Vegetable & Floriculture), BAC, Sabour for two years 2019-20 and 2020-21. There was two level of boron in form of borax (0.3 % and 0.4 %) and molybdenum (Mo) in the form of ammonium molybdate (0.15 % and 0.20 %) sprayed at 40 and 60 days after transplanting. Four curd cutting techniques were applied viz., intact curd (S1), scooping (S2), cross cutting (S3) and one fourth curd removal (S4) on variety (Sabour Agrim) the design of the experiment was Factorial Randomised Block Design with 36 treatment combinations which were replicated thrice. Curd scooping significantly influenced days to 50 % flowering (127.19 days) than that of no scooping. Curd scooping also significantly out yielded than no curd scooping for seed yield and other attributes viz., plant height (82.99 cm), days to 50 % flowering (127.43 days), number of flowering stalk per plant (10.17), days to maturity of siliqua (183.06 days) and number of siliqua per plant (2019.71). Central curd scooping resulted in higher per plant seed yield (48.67 g) than that of intact curd. Seed yield per plot obtained from scooping was (324.25 g). The highest germination % was obtained in seed produced from scooping ((91.01 %) followed by one fourth curd removal (88.75 %) and cross cutting (87.50 %). Maximum plant height (84.41 cm), days to 50 % flowering (126.97days), number of flowering stalks per plant (9.86), days to maturity of siliqua (180.88 days) number of siliqua per plant (1943.90), seed yield per plant (43.45 g), seed yield per plot (300.50 g) and seed germination percentage ((90.37 %) were obtained when (M5, boron 0.3 % with molybdenum 0.15 %) applied through foliar application. Scooping (S2, central curd cutting) significantly superior to rest of the treatments. M5 (boron 0.3 % with molybdenum 0.15 %) proved the best treatment combination in this study. Therefore, it may be concluded that the scooping (S2) along with foliar application of 0.3 % boron and 0.15 % molybdenum at 40 days 60 days after transplanting was found beneficial for getting more seed yield with higher benefit-cost ratio. These treatment was also found outstanding for better seed quality like higher germination per cent and 1000 seed weight whereas, treatment combination scooping of curd and foliar spray of micronutrient could 0.3 % ranked second in merit.EnglishThesis
