#faba bean

Nitrogen, Phosphorus and Zinc are main and expensive inputs in crop production. But the repeated excessive used of these fertilizer are costly and may harmful for environment. A considerable amount of nutrient is left unutilized and may have positive impact on subsequent crop. A two years experiment was conducted to evaluate the effect of nitrogen (N) phosphorus (P) and zinc (Zn) on maize hybrid and their carry over effect on subsequent faba bean at the University of Agriculture, Peshawar, Pakistan during 2013-2014 and 2014-2015. Randomize complete block (RCB) design having three replication was used. Three levels of N (150, 200 and 250 kg ha-1), P (75, 125 and 175 kg ha-1) and Zn (5, 10, 15 kg ha-1) along with control were applied to maize followed by faba bean grown on same plots without fertilizer application. Days to emergence of faba bean were significantly affected by year. More days to emergence of faba bean were recorded in 2013-2014 compared to 2014-2015. Days to maturity (DM) and biological yield (BY) of maize were significantly enhanced with each increment of N, P and Zn and maximum BY was recorded at N (250 kg N ha-1), P (175 kg p ha-1) and Zn (15 kg Zn ha-1) across both years. The DM were higher with 250 kg N ha-1, 75 kg P ha-1 and 15 kg Zn ha-1. These elements significantly enhanced days to flowering (DF) and BY of subsequent faba bean. It is concluded that 250 kg N ha-1, 175 kg P ha-1 and 15 kg Zn ha-1 performed better and recommended for obtaining maximum BY of maize and subsequent faba bean.
