Effect of Different Crop Establishment Methods and Fertilizer Sources on Growth, Yield Attribute and Yield of Rice (Oryza sativa L.)

Abstract

The influence of different crop establishment methods and fertilizer sources on growth attributes and yield of rice was studied during Kharif season of 2009 and 2010 on lateritic soils. The experiment was laid out in split plot design replicate thrice with five crop establishment methods (transplanting, pre-monsoon dibbling of seeds, dibbling of seeds with the onset of monsoon, transplanting of seedling by Thomba method and system of rice intensification) in main plots and three fertilizer sources (recommended dose of fertilizers-120:60:60 kg NPK ha^-1, placement of urea-DAP briquettes and placement of urea-suphala briquettes) in sub plots. From the present investigation, it can be concluded that for growing kharif rice under upland situation, crop need to be established by transplanting method and amended with urea-DAP briquettes (@ 168.75 kg ha^-1), to obtain higher yield. However, under inadequate rainwater for puddling, Thomba method with urea-DAP briquettes (@ 168.75 kg ha^-1) is suitable, and under labour scarcity condition, pre-monsoon dibbling of seeds with urea-DAP briquettes (@ 168.75 kg ha^-1) is one of the alternatives to conventional transplanting method under upland conditions.
