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.

Simple yield-density equations for quantifying additive intercrops

Yield-density equations are not well explored in additive intercrops. A modification of the standard asymptotic yield-density equation for application to additive intercrops was proposed, and in turn, derived equations were found. With wheat (Triticum aestivum L.)/faba bean (bean; Vicia faba L.) intercropping systems, as an example, the equations were applied to quantify seed yields in three field experiments. Although, the standard asymptotic yield-density equation quantified each of the sole crop and the intercrop yields of the major component (wheat) well for all the three experiments, the modified version worked well in only one of the experiments. Even though the response of the minor component (bean) was not consistent across the experiments, in one of the experiments, in addition to using modified standard yield-density equation to quantify the total intercrop (wheat + bean) yield (plus sole crop of the minor component; bean), the wheat intercrop and bean intercrop yield were quantified simultaneously using the equations proposed here. In conclusion, for a standard additive intercrop, the proposed yield-density equations can quantify the yields well and should be adopted by others using similar design.

Performance of five Faba bean varieties under different irrigation intervals and sowing dates in newly reclaimed soil | IJAAR

By: Ekram Ali Megawer, Ahmed Mohamed Ali EL-Sherif, Mohamed Sarhan Mohamed Key Words: Faba bean, Varieties, Irrigation intervals, Sowing dates, Yield and yield components

In order to study the effect of Irrigation and sowing date on plant characteristics, chemical and yield traits of five Faba Bean cultivars, an experiment was conducted in two growing seasons in the farm of the Faculty of Agriculture, Demo, Fayoum University, Egypt. Using split-split plot in RCBD with three replications. Irrigation intervals (I) was considered as the main plot in the three intervals (irrigation every 20, 30 and 40 days). Three sowing dates (22ndOct., 7thand 22ndNov.) were arranged in the sub plot. The sub-sub plots were varieties (Nubaria1, Nubaria2, Giza3 improved, Sakha1 and Sakha2). Results indicated that the effect of irrigation every 20 days (I1) surpassed the others two where it produced higher values of plant height (87.34cm), seed yield (1.81ton/feddan) and carbohydrate % (46.73%).

Faba is as tall as a 11 year old and I'm okay with that
