Effect of water regime and palm mass on cultivation of green pepper - DOI: 10.7127/rbai.v1601263

Resumo

In this study, we aimed to evaluate the agronomic behavior of green peppers subjected to different water regimes and masses of forage cactus incorporated into sandy soil in a tropical climate. The treatments were organized in a 4 × 4 factorial scheme, with water regimes and forage cactus masses incorporated into the soil in a randomized block design. The results allowed us to observe an isolated significant difference for each factor studied. The water regime RH=100% of the vessel capacity (VC) and mass density of 100 g dm−3 of forage cactus incorporated into the soil positively affected the plant height variables, stem diameter, total chlorophyll, and water potential; specifically, these treatments were superior to soil with water restriction and without the addition of forage palm by 63%, 15%, 61%, and 71%, and 87%, 85%, 81%, and 63%, respectively. The doses of soil conditioner masses containing 0 g dm−3 and 100 g dm−3 of palm in the soil showed the best results for the number of fruits (3.25 and 2.00 fruits), number of commercial fruits (2.0 and 1.5 fruits), and fruit length (88.87 mm and 95.92 mm). Forage cactus mass of 100 g dm−1 of Quartzarenic Neosol and 100% VC irrigation water regime is the most recommended treatment for the protected cultivation of green pepper, as it positively influences productivity and the morphophysiological characteristics of the crop.
