ABSTRACT
A field experiment was conducted to “effect of different levels of nitrogen, phosphorus and potassium on the growth and yield of cabbage Cv. Varun in Pithoragarh Hills.” All three nutrients (nitrogen, phosphorus and potash) were given in eleven different combinations with or without farmyard manure. An experiment was conducted with cabbage during October 2021 to February 2022 at the Krishi Vigyan Kendra, GBPUA&T, Gaina, Pithoragarh, Uttarakhand, India. Four levels of nitrogen (N) @ 0, 120, 190 & 260 kg per hectare, three levels of phosphorus (P2O5) @ 0, 85 & 115 kg per hectare, three levels of potassium (K2O) @ 0, 60 & 100 kg per hectare and two levels of farmyard manure (FYM) @ 15 & 20 tons per hectare were applied in a Randomized Block Design with three replications. Nitrogen @ 120 kg ha-1, phosphorus@ 85 kg ha-1, potassium (K2O) @ 60 kg ha-1 and farmyard manure 20 ton ha-1 was more effective and produced the highest fresh weight of head (1.883kg), marketable head yield (75.33 ton ha-1). This treatment was also more profitable than the rest of the treatments. The present studies “effect of different levels of nitrogen, phosphorus and potassium on the growth and yield (Plant height, germination percent, head length, head diameter, weight of head, yield g plot-1 and yield kg ha-1) of cabbage (Brassica oleracea var. capitata) Cv. Varun in Pithoragarh Hills” found significant effect on T7 treatment in all over 11 treatments with control. Among all treatment combinations, fertilizer dose of nitrogen, phoshphorus, potassium and farmyard manure 120:85:60 kg & 20 ton ha-1 (T7 treatment) was found to be most and best of cabbage cultivation. The economics of fertilizers were also worked out on the basis of current market prices and it was found that use of fertilizer was profitable.
