(Instituto de Investigaciones Agropecuarias, INIA, 2010)
Contribuition of nitrogen from biological nitrogen fixation, nitrogen fertilizer and soil nitrogen on the growth of the common bean and cowpea
(INST AGRONOMICO, 2011)
Biological nitrogen fixation (BNF) constitutes a valuable source of this nutrient for the common bean Phaseolus vulgaris L and cowpea Vigna unguiculata (L.) Walp., being its avaibility affected by mineral N in the soil ...
Morphogenetic and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen according to season
(Sociedade Brasileira de Zootecnia, 2012-03-01)
The objectives of this study were to evaluate morphogenetic characteristics and tillering dynamics in Tanzania grass fertilized and non-fertilized with nitrogen, under intermittent grazing, in the spring and the summer. ...
Harvesting Systems, Soil Cultivation, and Nitrogen Rate Associated with Sugarcane Yield
The adoption of mechanical harvesting of green cane gives rise to concerns as to whether systems developed under burnt cane harvesting are applicable to a green cane harvesting system. In particular, tillage, which is an ...
