Influence of water levels and mineral fertilization on nutrition and yield of upland rice
01/Aug/2003
In order to achieve more sound fertilizer recommendations, knowledge about nutritional requirements of rice in different growing systems is fundamental. The objective of this paper was to evaluate the effects of water levels on nutrition and nutrient exportation by upland rice (cultivar IAC 201) under two levels of mineral fertilizer. Experiments were conducted in the growing seasons of 1994/95 and 1995/96 on a Typic Haplustox, in Selvíria, State of Mato Grosso do Sul, Brazil. The experimental design was of randomized […]
Effects of sprinkler irrigation management on emergence of maize in different soils
01/Dec/1999
Inadequate water application is one of the reasons of poor initial plant stand for irrigated maize. This problem is more serious in some soils with superficial crusting after sprinkler irrigation or rainfall. The effect of different water management criteria on maize emergence was evaluated in three soils: Dark-Red Latosol (LE), in Sete Lagoas, and Yellow-Red Latosol (LV) and Alluvial soil, in Janaúba, in Minas Gerais, Brazil. The treatments were based on different strategies for supplying water to soil. A combination […]
