Effect of Different Fertilizers (Bio, Organic and Inorganic Fertilizers) on Some Yield Componants of Rice (Oryza Sativa L.)

Abstract

A field experiment was conducted at the Demonstration farm of College of Agricultural Studies, Sudan University of science and Technology, in season (2011/2012 and 2012/2013) to study the effect of biofertilizer (EM), organic fertilizer (pellet granule and compost), and inorganic fertilizer (urea + superphosphate), and (urea + superphosphate + compost) on yield components of two varieties of Rice (kosti 1 and omgar). Application of EM gave a positive increase in all of the studied parameters. Moreover, the interaction of EM with kosti 1 gave more significant increments. All treatments have a significant affect compared with control at all parameters studied (spike length /cm, number of seeds/spike, 1000-seed weight, number of reproductive tillers/plant, yield tons/hectare and harvest index HI). The high yield 2.97 t/ha was obtained by EM x kosti 1followed by urea+sup+comp, pellet granule and urea+sup in both season while the control recorded less yield (1.07) t/ha.
