Integration of npk with different granular organic manures on yield attributes and yield of lowl and rice

Field investigation was conducted at Annamalai University Experimental Farm to study the impact of integration of graded dose of NPK and different granular organic manures on growth and yield of low land rice (Oryza sativa L.) The experiment was laid out in a Randomized Block Design (RBD) with nine treatments. All the treatments significantly influenced the yield components of lowland rice. Results of the experiment revealed that 75 percent NPK + Azophos @ 2 kg ha-1 + pressmud based organic manure granules @ 125 kg ha-1 + distillery ash granules @ 125 kg ha-1 recorded enhanced values of yield components viz., number of tillers hill-1, number of filled grains panicle-1 and seed yield as compared to other treatments. The application of 50 percent NPK + Azophos 2 kg ha-1 resulted in the lowest values of these yield components and yield of lowland rice.
