An experiment was conducted during the years 2009 and 2010 to evaluate the effects of Urochloa forage straw and nitrogen fertilization on soil properties, nutritional foliar content, index of foliar chlorophyll (IFC) values, ...
Nitrogen supply affects seed yield and quality in tomato plants
(2022)
Nitrogen fertilization is one of the main practices in agriculture and its effects on yield and quality of most commodity products are widely known. However, the nitrogen response in seed production is still not well ...
Application of different nitrogen doses to increase nitrogen efficiency in Mombasa guinegrass (Panicum maximum cv. mombasa) at dry and rainy seasons
(2017-12-01)
Nitrogen is the nutrient that most influences productivity and pasture quality but nitrogen fertilization efficiency still needs to be increased. The objective of this work was to study the efficiency of nitrogen sources ...
