Abstract

Purpose: Cowpea (Vigna unguiculata (L.) Walp.) is one of the most widely cultivated food crops in Niger, but Niger's agriculture remains dependent on agro-climatic and edaphic conditions. The main objective of this study is to evaluate the combined effect of zai and the number of plants per crop on cowpea growth and yield parameters. Methodology: Two (2) factors were studied: the zaï’s factor (A) and the number of plants per crop factor (B). The experimental design used is a total randomization device with three (3) repetitions. Findings: The results showed that the A2B2 treatment is characterized by the variables, good yield of pods, seeds, biomass and dry matter. A2B2 treatment had the best grain yield compared to A2B1. The average grain yield ranges from 173.3±68.1 to 1250±720 (kg/ha). However, there is no significant difference between the different treatments on the parameter of biomass. Unique Contribution to Theory, Practice and Policy: In this study, the best performance is obtained with two (2) plants per crop without zai techniques.

宰仔对豇豆产量的影响在迪法市区迪亚戈农业系统的农民环境

目的:豇豆(Vigna unguiculata)(Walp.)是尼日尔种植最广泛的粮食作物之一，但尼日尔的农业仍然依赖农业气候和地理条件。本研究的主要目的是评价宰和单株数对豇豆生长和产量参数的综合影响。方法:研究两(2)个因素:zaï’s因子(A)和每作物株数因子(B)。试验设计采用全随机化装置，重复三(3)次。结果表明:A2B2处理具有豆荚、种子、生物量和干物质产量均较高的特点。与A2B1处理相比，A2B2处理的籽粒产量最好。平均产量在173.3±68.1 ~ 1250±720 (kg/ha)之间。但不同处理间生物量参数差异不显著。对理论、实践和政策的独特贡献:在本研究中，在不采用zai技术的情况下，每茬作物种植两(2)株获得最佳性能。
