Effects of Light Intensity on Growth of Some Tropical Forage Species. I. Interaction of Light Intensity and Nitrogen Fertilization on Six Forage Grasses1
In order to determine the response of some tropical grass species to low light situations such as under plantation crops, seasonal cloud cover, etc., six tropical forage grasses were evaluated over a 20 month period on an Oxic Haplustoll in Hawaii (100 m above sea level) under four light regimes (100, 70, 45, and 27/, daylight using polypropylene netting) in the field. The forage grasses evalua...

15 صفحه اولEfficiency of nitrogen fertilization in spring wheat
An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...
متن کاملEvaluation of Cross-fertilization in Forage Crops
In the improvement of forage crop varieties knowledge of~e .extent of cross-fertilization is of value for (1) de~g the extent and randomness of crossing in breedmg procedures, (2) estimating varietal changes due to contamination and mechanical mixtures, and (3) evaluating effects of cross,fertilization in the development and production of synthetic and hybrid combinations. Genetic markers can a...
