Influência de práticas conservacionistas na umidade do solo e no cultivo do milho (Zea mays L.) em semiárido nordestino

Abstract: RESUMO O semiárido brasileiro possui capacidade produtiva limitada em razão das suas características intrínsecas em relação à vegetação, ao clima e ao solo. A cobertura do solo, uma prática recomendada para essa região, favorece a infiltração, proporcionando melhor aproveitamento da água da chuva e contribuindo para o desenvolvimento das culturas, ao reduzir a perda de água por escoamento superficial. Nesse contexto, este trabalho teve como objetivo avaliar os efeitos de diferentes tipos de cobertura na manute… Show more

“…In the present study, the reduction in phenophase III was most associated with the effects of water depth on phenophase II, intensifying the second-order daughter cladode production to the detriment of their size, which was smaller in mulch-based and intercropping systems (data not shown). The presence of mulch favors water storage and lower temperature, and increase cycling and soil nutrient content, contributing to the plant development (Borges et al 2014). Consequently, mulch stimulates the second- order daughter cladode production, as observed in this study.…”

“…However, it must be emphasized that there was no occurrence of water deficit during the cultivation of soybean (Figure 1). It is likely that, if it had occurred, the importance of the presence of straw in the treatments would be increased, due to its potential to reduce water losses by evaporation (Borges et al, 2014). Another aspect that needs further investigation is related to the cumulative effects of straw or roots on the soil properties, and on the productive performance of soybean in long-term experiments.…”

“…The maximum use efficiency of the nutrient by the plant is determined by the maintenance of soil moisture, with expressive effects on the increase of yield (Borges et al, 2014;Silva et al, 2015). In this context, the use of water retainers can favor the maintenance of moisture in the soil, because it contributes to retaining water and gradually releasing it to the plants (Oliveira et al, 2004;Moghadam et al, 2011), which can improve the fertilizer-N use, potentiating the yield and reducing risks of losses of the nutrient.…”
