Effect of different levels of customized fertilizer on soil nutrient availability, yield and economics of onion
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 2
Abstract
A field experiment was conducted to study the effect of different levels of customized fertilizer (CF) on soil nutrient availability, yield and economics of onion. The results revealed that the significantly highest plant height (57.77cm), stem diameter (6.03cm) and bulb diameter (15.13cm) at the time of harvest, fertilizer use efficiency,bulb yield (22.34 t ha-1) and benefit:cost ratio (2.56) of onion were recorded in 100 % recommended dose of NPK through CF in three equal split doses. The significantly highest available nitrogen (213 kg ha-1), phosphorus (14.42 kg ha-1) were recorded in 125 % recommended dose of NPK through CF in two equal split doses and available K (804 kg ha-1) in 100 % recommended dose of NPK through CF in three equal split doses over the rest of the other treatments. The application of 100% recommended dose of fertilizer (100:50:50 N:P2O5:K20 kg ha-1) either two or three splits through CF to onion appears to be improving soil fertility, yield and yield contributing character of onion and getting higher net monetary returns.
