In Egypt natural sun drying is one of the most common ways to conserve agricultural products Cereals, legumes, fruits, vegetables and spices are spread on the ground to be dried by sun and wind. During drying these products are neither protected against dust and rain nor against rodents, birds and insects. Poor quality due to contamination with partly pathogen microorganisms and high losses caused by uneven or incomplete dehydration are the characteristics of natural sun drying. To meet the food requirement of the growing population and moreover to provide high quality products for export is necessary to develop suitable methods of drying. An economical use of oil or gas heated dryers as common in industrial countries is restricted to co-operatives or largeplantations because of the high initial costs and the need for expensive fossile energy. |

Conteúdo: |
The objective of this work was to evaluate macronutrient uptake and export by transgenic corn hybrids under medium and high fertilization levels. For each fertilization level, a randomized complete block design was carried out in the summer crop season, under no-tillage and supplementary irrigation, with four cultivars and four replicates. Plants were sampled throughout the entire cycle and separated into leaves, stalk, husk, cob, and grains for the determination of dry matter mass and accumulation of macronutrients in the different growth stages. Under the high fertilization level, a greater dry matter mass and nutrient uptake were observed, but grain yield was similar to that under the medium fertilization level. The uptake of N, P, Ca, Mg, and S occurs until later in the cycle of the transgenic cultivars, which also showed lower concentrations of P, K, and S in grains, when compared to older hybrids. The differential behavior of the evaluated cultivars under different fertilization levels indicates the need of updating and improving nutritional management and fertilizer recommendations for the corn crop. |
