Models for predicting broadleaf vegetable responses to green manures mixtures in semi-arid environment
نویسندگان
چکیده
The broadleaf vegetables require large amounts of nutrients to provide a high productivity, and quality products, mainly due their short period development growth. green manuring has emerged as viable alternative these requirements for vegetables, from spontaneous species in the Caatinga biome. Thus, aim this study was evaluate estimate maximum physical economic efficiencies lettuce arugula agro-economic characteristics monocropping function equitable quantities Merremia aegyptia Calotropis procera biomass mixtures at different growing seasons, using polynomial exponential models, based on criteria biological logic growth production cultures, significance regression mean square, value coefficient determination (R2), parameters, maximization productivity profit. types models chosen estimated with good precision R2 values. agronomic (physical) efficiency made possible incorporation into soil 47.38 42.23 t ha-1 M. C. procera, respectively, leafy reached 45.96 33.61 ha-1, respectively. rates return obtained cultivation optimized mixture were 2.6 1.5 those achieved control treatment (without fertilization),

In arid and semi-arid environments, groundwater plays a significant role in the ecosystem. In the last decades, groundwater levels have decreased due to the increasing demand for water, weak irrigation management and soil damage. For the effective management of groundwater, it is important to model and predict fluctuations in groundwater levels. In this study, groundwater table in Kashan plain ...
