Effect of integrated nutrient management on indian mustard and soil fertility

Abstract

A field experiment was conducted during rabi season of 2008-09 and 2009-10 at Bichpuri (Agra) to study the effect of integrated nutrient management on productivity, quality and uptake of nutrient by Indian mustard and soil fertility. Application of 75% NPK and 5 t FYM ha-1 produced significantly higher seed (2.09 t ha-1) and stover (6.00 t ha-1) yield over either only 100% inorganic fertilizer (4%) or FYM (50%). On an average, seed and stover yields of Indian mustard increased by 37.4 and 45.8, 62.8 and 70.6 and 74.0 and 83.5 % with application of 50, 75 and 100% over control, respectively. Application of FYM (5 t ha-1) alone enhanced the seed and stover yield by 20.6 and 24.1 % over control. The maximum protein (429.3 kg ha-1) and oil (869.0 kg ha-1) yields were also recorded with 75% NPK + 5 t FYM ha-1. The highest uptake of N, P, K and S was also associated with the conjunctive use of 75% NPK and FYM treatment. The maximum values of available N (175 kg ha-1), P (12.0 kg ha-1) and K (155.0 kg ha-1) were noted under 100% NPK alone. On the other hand, maximum value of availableS (17.1 kg ha-1) was noted with 75% NPK + 5 t FYM ha-1.
