Produtividade e qualidade de frutos de meloeiro sob osmocondicionamento e salinidade da água

Abstract

Croplands with intense evaporation, drainage deficiency and inadequate use of fertilizers have increased problems with salinity, causing losses in crop yields. It was aimed to evaluate the productivity and quality of melon fruits Cantaloupe type due to the priming of seed and levels of water salinity. The experiment was conducted in split type 2 x 4 plots allocated in a randomized block design with four replications. The plot consisted of 4 irrigation water salinity levels (0.3, 1.0, 1.7 and 2.4 dS m-1 ) and sub plots of plants from seed treated and not treated with saline NaCl. It was evaluated the characteristics related to production and quality of melon fruit. The cultivar used was the Rangers of the Cantaloupe group planted in the spacing of 2.0 x 0.4 m. The priming of the seeds NaCl solution affected the melon yield components in the fruit mass was higher in plants originated from seeds treated with NaCl. In the formation of productivity, she became apparent the fruit mass contributed more than the number of fruit per plant and this difference was significant only under low water salinity of 0.3 dS m-1. The quality of the melon fruit was not affected by seed priming with NaCl and plants irrigated with saline water of 2.4 dS m-1 reduced their production and fruit quality of melon.
