Effect of Different Levels of Compost and Nitrogen Fertilizers on Growth and Yield of Broad Bean (Vicia faba l.) Under Silty Clay Soil Conditions تأثير المستويات المختلفة من الکومبوست والأسمدة النيتروجينية على نمو وإنتاج الباقلاء (Vicia faba L.) في ظروف التربة الطميية الطينية

Abstract

The field experiment was conducted at Arbat location in sulaymaniyah governorate, Iraq. The main aim of this research is, to evaluate the impact of adding various levels of compost (Cattle Manure) and nitrogen (Urea) rates on Broad Bean (Vicia faba L.) yield and yield components. Experimental treatments have been organized and a factorial experiment was laid out in a complete randomized block design with three replicates. The treatments included three levels of compost, and three levels of nitrogen incorporated into the soil. The main results could be summarized as, the application of compost, nitrogen and the interactions, the vegetative growth parameters, plant height (cm), number of branches plant-1, biological yield (g), pod length (cm), number of pods plant-1, average of pod weight (g), seeds weight (g pod-1), yield of seeds (Mg ha-1), total yield of pods (Mg ha-1), number of nodules plant-1 and % nitrogen, % protein in seeds of Broad Bean plant from Arbat location, were significantly increased by increasing the level of compost application from 0, 5 to 10 Mg ha-1. Also the vegetative growth parameters, broad bean yield and pods quality as well as nutritive value of broad bean were significantly increased with increasing the level of nitrogen application from 0, 100 to 150 kg ha-1.
