Abstract
A field experiment was carried out to study combined effect of organic and/or inorganic N fertilizer on growth and yield of chickpea plants grown on sandy soil using N-15 tracer. Results revealed an increase in weight of shoot and seed yields in the plot amended with cow manure (50% MF + 50%OM) and, relatively the increase was 21.84 and 38.78% over control, respectively. The highest N accumulated in plant tissues of shoot (49.0 g/plot) and seeds (155.0 g/plot) as compared to the control (100% MF) which recorded 23.1 and 59.0 g/plot, respectively.
