Cultivo do maracujazeiro amarelo sob lâminas de irrigação e consórcio com feijão-caupi.

Abstract

The objective of the present study was to identify the best strategy in the use of the irrigation water heads for yellow passion in monoculture and consortium with caupi-bean, evaluating the growth, productivity, the response of the crop systems and the water use efficiency of the passion crop submitted to different irrigation water heads. The experiment was conducted under field conditions, in a randomized 5 x 2 split plots block design with five irrigation heads (60, 80, 100, 120 and 140% of the field capacity) and two cropping systems: passion in monoculture and intercropped with cowpea, with four replications. The data were submitted to analysis of variance, test F, with regression analysis for the quantitative irrigation factor and comparison of means, by the Tukey test, for the qualitative crop system factor. The highest yields of both crops were obtained with the highest water treatment. The cultivation system used for passion, single or intercropped with cowpea bean did not influence the passion behavior. Although the production of the intercropped passion fruit was not statistically different from that of the single crop, the complementary production that the bean provides in intercropping makes the consortium an alternative to smallholder agriculture. The water use efficiency for the passion decreased with the irrigation water, obtaining the greatest water use efficiency when the passion was irrigated with a water head equivalent to 60% of the field capacity.
