Abstract

In order to evaluate the sole impact of biochar on yield and yield components of mungbean crop, a pot experiment was conducted at Agronomy Research Farm, Agriculture University Peshawar, Pakistan during summer 2013. The experiment was laid out in completely randomized design having four repeats. The treatments were consisted of 5 levels of biochar (25, 50, 75, 100 tons ha-1) along with control. Early flowering (36) and maturity (81) was recorded in biochar treated plots as compared to control. The biochar levels significantly improved pods plant-1 (23), pods length (9.2 cm), grains pod-1 (11), 100 grains weight (6.8 g), biological yield (28.3 g pot-1), grain yield (4.2 g pot-1) and harvest index (14.87 %). While days to emergence of mungbean were non-significant. Hence it was concluded from the experiment that the application of biochar at the rate of 25 tons ha-1 is beneficial for improving mungbean grain yield in Semi-arid region.
