Abstract

Irrigation control and the location of fertilizer in the soil are predominant criteria for successful crop production. The objective of this study was to evaluate how the bean crop depends on the depth of fertilizer deposition and irrigation depth in no tillage in a clayey-texture Latosol. We used a combination of five depths of water replacement for evapotranspiration (ETo) from the culture (25, 50, 75, 100 and 125%) and four depths of fertilization (0.05, 0.09, 0.12, and 0.17 m) in a completely randomized design (CRD) with three replications. We used a tractor, New Holland brand, model TL 85 E, a planter brand BALDAN model PLB 3:01 and an irrigation pivot brand, FOCKING. The plot used consisted of 240,000 plants ha-1 of the cultivar BRSMG Marepérola. For depth of fertilizer there was no significant difference for the variables number of pods per plant and mass of 100 grains. The depth of fertilization influenced the number of grains per pod and yield. The depths of ETo influenced the weight of 100 grains, number of pods per plant, number of grains per pod and yield.
