The corn used in the production of green ears presents a higher commercialization value compared to corn grain and its demand occurs throughout the year. Due to a small specific cultivation availability and the lack of important information regarding this kind of cultivation, this work has had the objective to evaluate the agronomic characteristics and the production performance in the cultivation of corn to be harvest green in both organic and conventional systems. The experiments have been conducted in "Agência Paulista de Tecnologia dos Agronegócios-Polo Regional do Extremo Oeste", in Andradina-SP, for two agricultural years. The experimental design adopted was in occasionals blocks with 4 repetitions. The treatments have been constituted by the combination of seven cultivate corns: AG1051, AG4051, XB7116, 20A55, BM3061, 2B587 (hybrids) e Cativerde 02 (variety) and 2 systems of organic and conventional cultivation. The organic system presented smaller development and productivity in a delayed period of time. The cultivate 2B587 must be highlighted due to its precocity and smallest height, and BM3061 for presenting corn ears with the longest length and diameter. The cultivates 2B587 and BM 3061 showed a value 14 and 9%, respectively, higher of total number of ears per hectare. The cultivates AG4051 and Cativerde 02 showed taller and less productive in both systems.The cultivates BM3061, 2B587, XB7116 and AG1051 can be recommended in both systems by being most productive in decreasing order.

Nowadays the food production systems tend to include the sustainable management of soil and water. One of the main obstacles to the organic cultivation of common bean is the fertilization management. This study aimed to evaluate doses of organic fertilizer containing slaughterhouse residues (1.0 t ha−1, 1.5 t ha−1, 2.0 t ha−1 and 2.5 t ha−1). The experimental design was randomized blocks in a 4x2x2 factorial scheme, with 16 treatments and 4 replications. Plant dry weight; foliar diagnose; initial and final plant population; number of pods per plant, grains per plant and grains per pod; 1000-grain weight; and grain yield were evaluated. It was concluded that the methods and time of organic fertilizer application do not affect the production components and yield in common bean. The dose of 2.5 t ha−1 of organic fertilizer provided the highest common bean yield in 2012, but it did not express its maximum production capacity. © 2015, Universidade Federal De Goias (UFG).
