Effect of Intercropping of Different Varieties of Haricot Beans (Phaseolus vulgaris L.) and Maize (Zea mays L.) on Soil Fertility and Yield at Shashamene, Ethiopia

Maize (Zea mays) - Haricot bean (Phaseolus vulgaris) intercropping is a recent practice at shashamane district, west-Arsi Zone of Oromia region and there is an inadequate information on its productivity and soil fertility management. Poor soil fertility and lack of financial resources to purchase mineral fertilizers have emerged as the greatest biophysical constraints to improve agricultural productivity in the study area. Therefore, a field experiment was conducted at Shashamane district during the 2020 and 2021 crop growing seasons to evaluate the effect of intercropping maize and haricot beans on soil fertility and yield improvement. The experimental materials were one maize hybrid (BH-546) and three haricot bean varieties (Dinknesh, SER-119 and Nasir). The experiment was laid out in a randomized complete block design with three replications. The soil analysis result showed intercropping of maize-haricot beans were highly influenced soil total nitrogen and available phosphorus. Improvement of soil total N was found in plots where haricot beans was grown in an intercrop with maize. In contrast available P content was reduced in post-harvest soils of all plots in which maize was intercropped with haricot beans. Higher grain yield of maize and haricot beans were obtained from sole cropping compared to intercropping. Intercropping of maize with haricot bean had total LER value greater than one which showed the benefit of intercropping over mono-crops. The combined yields obtained from intercrops were more profitable than sole haricot beans and maize. Therefore, intercropping agro-ecologically suitable haricot beans with maize are advantageous in terms of grain yield and soil nutrient improvement than the corresponding mono-crops.
