Abstract
An experiment on maize crop with preceding legumes and nitrogen levels were carried out at the Research Farm of Agronomy, the University of Agriculture, Peshawar during 2011-2012 using summer legumes-maize cropping pattern. The summer legumes were sown in the summer gap (6065days) for grain, fodder and green manure purposes. Mungbean for grain and cowpea for fodder purpose and Sesbania was for green manure purpose using fallow as control. After legumes experiment each plot was split into four sub plots to accommodate four levels of N (0, 90, 120 and 150 kg ha -1 ) for maize. Data were recorded on emergence, plant height, grains ear -1 and ear weight. Soil parameters after legumes; pH, total soluble salts (TSS), electrical conductivity (EC), and calcium carbonate (CaCo 3) were not significantly affected by preceding legumes. Soil pH was higher in fallow plots while lower in plots previously cultivated with mungbean. Soil TSS, EC and CaCo 3
