Thesis, SKUAST-Jammu, India37136https://krishikosh.egranth.ac.in/handle/1/581020191288To work out the optimum date of transplanting, spacing and method of planting in midseason cauliflower, the present investigation was conducted on a popular local landrace namely SathiGobhi during the year 2022-2023. For marketable yield, the experiment was carried out with three spacings and three dates of transplanting,having 9 treatment combinations. For seed production purpose, two methods of seed production, three dates of transplanting and three spacings were tried. Both the experiments were replicated thrice in split plot design. For marketable yield, study revealed that 2nd date of transplanting i.e., 20th September was significantly superior for various growth and yield characters. Among spacings, 60 cm x 75 cm was significantly superior to all the growth parameters. However, at a spacing of 60 cm x 45 cm maximum curd yield (233.54q) was recorded.For seed purposes, the study revealed that transplanting on 20th September proved significantly superior for all seed yield characters except for days to 50% flowering and days to siliqua maturity. Among spacings, the parameters such as days to 50% flowering, days to siliqua maturity, number of siliqua per plant, seed yield per plant were recorded significantly superior at 60 cm x 75 cm spacing. However, characters such as seeds per siliqua, siliqua length, seed germination percentage, seed vigour index, were recorded significantly superior at a spacing of 60 cm x 60 cm. However, 1000 seed weight and seed yield per hectare (448.80 kg) were recorded significantly superior at 60 cm x 45 cm.Among different methods, in-situ method of planting was found significantly superior method with respect to most of the seed characters under study. In case of interaction, transplanting on 20th September following in-situ method significantly maximized seed yield per plant and seed yield per hectareEnglishThesis
