GRAIN YIELD OF DRY BEAN FERTILIZED WITH CATTLE MANURE UNDER RAINFALL CONDITIONS

Abstract

At the semi-arid region of the Centre-North of México, dry bean (Phaseolus vulgaris L.) is an important crop cultivated under rainfed conditions. Two varieties Flor de Junio Dalia and Pinto Coloso were evaluated in 2013 regarding the effect of the application of cattle manure on the grain yield of the two dry bean varieties: Flor de Junio Dalia (planted on June 21) and Pinto Coloso (on August 5), in triple row beds with in situ rainwater catchment under rainfed conditions. The system was used for the water catchment from “corrugation with Aqueel” and “tidge”. Manure doses and chemical fertilizer were 0, 10 and 20 t ha^-1 and 80-40-30 kg ha^-1 N, P y K, applied annually for three consecutive years. Treatments showing higher grain yield were 10 and 20 t ha^-1 of manure (2.3 and 2.1 t ha^-1) with Flor de Junio Dalia and Pinto Coloso (1.4 and 1.1 t ha^-1, respectively). Manure increased organic matter (OM) content in the first 10 cm of soil depth, and with 20 t ha^-1 the soil showed the highest content of NO₃ (14.85 mg kg^-1; 0-10 cm layer).
