Behavior vegetative of irrigated cowpea and fertilized crop under different doses of organic biofertlizante

The cowpea is itself one of the main components of the diet in the North and Northeast regions of Brazil, especially in the countryside. In the state of Ceará, this crop is grown in most growing areas; however, its nutritional deficiency is considered one of the main factors attributed to the low crop yield in soils of the coastal state. The objective of this study was to evaluate the development of cowpea due to different doses of organic bio fertilizer, produced by accelerated biodegradation of waste straw and inflorescence of coconut, Nim pruning and Cashew Tree pruning, compared to mineral fertilizer at different stages of development thereof. The design was a complete randomized block with five treatments and four replications, with four treatments consisting of different doses of organic bio fertilizer (0L, 2L, 4L and 6L/parcel 3m linear) and one with chemical fertilizer. The variables analyzed were: plant height, stem diameter and crown diameter. The chemical fertilizer gave higher values compared with doses of organic bio fertilizer applied to the crop in the case of the variables analyzed.
