Respuesta del cultivo de pimiento (Capsicum annuum L) al riego deficitario en la etapa inicial y de desarrollo en un suelo franco

The objective was to determine the effect of the irrigation deficit applied in the initial and development stage of Capsicum annuum L. (Solanaceae) crop, without affecting the performance. The treatments were 70%, 80%, 90%, and 100% (Control) of evapotranspiration crop (Etc). The experimental material was Quetzal hybrid, planted at a distance of 1.0 m x 0.5 m. The irrigation was carried out by drip with a frequency of two days and the calculations of the Eto were carried out by the evapotranspiration of reference of the evaporimeter tank type A. The treatments were distributed in a CRD (Completely Randomized Design) with four replicas. There were measured: the efficient use of water (kg/m3), plant height (cm), fruit weight (g), number of fruits per plant and performance (kg/ha). With the application of 80% of Etc, greater efficient use was obtained with 12.5 and 12.6 kg/m3. The plant height showed a significant difference (p < 0.05) at 27 and 37 days after transplanting (DAT), with the 20% of reduction being the highest average. The number of fruits per plant and the performance (t/ha) showed statistical differences (p < 0.05) due to the irrigation deficit action, 80% of the Etc had the highest performances with 8.8 fruit/plants and 20.1 t/ha. The weight (g) of the fruit was similar in all treatments, between 112.2 and 114.1 g/fruit. Plants of C. annuum tolerate a 20% reduction of the irrigation sheet without affecting production and thus obtain greater efficiency of the water use.
