Abstract

Understanding the effects that water deficiency has on plants is of fundamental importance for the development of management strategies. Therefore, the objective of this work was to evaluate the application of levels of full and deficient irrigation in the development and productivity of the cultivar IAC 505. An experiment was carried out in randomized blocks, with five irrigation depths (L1 = 100%; L2 = 94%; L3 = 63%; L4 = 27% and L5 = 8% of field evapotranspiration, ETc), with 4 repetitions. Evaluations of growth, interception of photosynthetically active radiation, dry mass of the aerial part and yield of pods were carried out. Based on the results, it was found that irrigation depths below 63% of ETc, can reduce plant growth by 32%, reduce the interception of photosynthetically active radiation by 54%, provide less accumulation of dry mass, reaching 49% reduction and cause losses of up to 64% in the pod yield of the peanut cultivar IAC 505.
