Yield and Yield Attributes of Upland Rice (Oryza sativa L.) as Influenced by NK Levels and FYM Substitution

A field experiment was conducted in the farmer's field near to the College of Agriculture, Padannakkad, Kasaragod during the kharif season of 2015 to study the influence of different levels of N and K on yield attributes, yield of upland rice and to assess the possibility of substitution of inorganic N by FYM. The results revealed that application of 120 kg N ha⁻¹ with 50 per cent substituted as FYM and 60 kg K₂O ha^{1registered the highest grain yield (2822 kg ha−1) and straw yield (3560 kg ha−1) in upland rice. It also significantly increased the yield attributes like number of productive tillers hill−1, panicle length, panicle weight, total number of spikelets per panicle and number of filled grains panicle −1in upland rice.}
