Phosphorous as the major yield limiting nutrient for maize in the river basin areas of western Nepal
Maize is a heavy feeder crop but not always higher quantity of chemical fertilizers leads for higher grain yield. Objective of the study was to identify the major yield limiting macro nutrient for maize in the river basis areas. Field experiments were conducted at four locations viz. Dasharathpur, R...

Maize is a heavy feeder crop but not always higher quantity of chemical fertilizers leads for higher grain yield. Objective of the study was to identify the major yield limiting macro nutrient for maize in the river basis areas. Field experiments were conducted at four locations viz.

Different doses of nitrogen, phosphorous and potassium fertilizers were applied. Planting was done in the summer season of 2010 and 2011.
