ABSTRACT

An experiment was conducted at Newly Developed Research Farm of the University of Agriculture Peshawar to observe the effect of pigeon pea green manuring on performance and subsequent nitrogen fertilizer requirement of wheat crop during 2013 and 2014. The experiment was carried out in randomized complete block design with split plot arrangements having four replications. Pigeon pea green manuring treatments as 0, 30, 60, 90 and 120 days post emergence were allotted to main plots, where crop was incorporated in soil at different days after emergence (DAE), this was done in previous season before sowing of wheat crop, whereas nitrogen levels as 0, 30, 60, 90 and 120 kg N ha-1 were allotted to sub plots in the field where wheat crop was sown. Data were recorded on emergence m-2, days to maturity, plant height, thousand grains weight, biological yield and grain yield of wheat. The integration of pigeonpea green manuring with nitrogen levels significantly increased wheat growth, yield and yield components. In case of green manuring, plots in which pigeon pea crop was incorporated at the age of 90 days showed maximum plant height (103.3 cm), thousand grains weight (45.2 g), biological yield (10199 kg ha-1) and grain yield (3641 kg ha-1) of wheat. The application of nitrogen at the rate of 120 kg N ha-1 significantly increased plant height (102.5 cm), thousand grains weight (43.8 g), biological yield (10674 kg ha-1) and grain yield (3766 kg ha-1) of wheat. The incorporation of green manures 90 days posts emerged pigeon pea with 90 and 120 kg N ha-1 produced taller plants with height of 104.4 and 104.0 cm, heavier grains with 52.0 and 50.8 g weight per thousand grains, higher biological yield 11986 and 11859 kg ha-1 and optimum grain yield 4161 and 4147 kg ha-1. Results indicated that the integration of 90 days older pigeon pea green manuring with 90 kg nitrogen ha-1 can be the best recipe for better and sustainable wheat production.
