Effect of Nutrients Management Management Practices on Growth and Yield Parameters of Gobhi Sarson (Brassica napus spp. napus).

An experiment was conducted at Shivalik Agriculture Research and Extension Centre (SAREC), CSKHPKV, Kangra, Himachal Pradesh to study the response of nitrogen (N), phosphorus (P) and potassium (K) fertilizer as well as their combinations with farm yard manure (FYM), secondary and micro nutrients on growth and yield of gobhi sarson during rabi 2019-20. The experiment consists of eleven treatments which replicated thrice under Randamized block design (RBD). Results of the experiment revealed that yield attributes like plant height, number of primary and secondary branches per plant, number of siliquae per plant, number of seeds per siliqua, and1000 seed weight were maximum in 150 per cent NPK was applied and minimum control. Seed and stover yield of mustard was significantly influenced with fertilizer application. Application of 150 per cent NPK resulted in significantly higher seed yield, stover yield as well as biological yield of gobhi sarson. Yield responses to fertilization were ranked as NPK>NP>NK>PK, illustrating that N was the most limiting nutrient in rapeseed productivity following P and K. The seed yield (1451.2 kgha-1) and stover yield (2815.7 kgha-1) increased progressively and significantly with 150% NPK application over recommended fertilizer dose followed by application of 100 per cent NPK in combination with farmyard manure (FYM).
