PALLED, Y.RVENKATESH, R.2019-10-222019-10-222001-08-02Th-5808http://krishikosh.egranth.ac.in/handle/1/5810132402A field experiment was conducted to study the 'Response of hybrid maize to row application of organics and nitrogen in Transitional Tract of Northern Kamataka' at Main Research Station, Dharwad on medium black soil during kharif, 1997. Treatment combinations consisted of three organic sources (FYM @ 1 t/ha, poultry manure @ 1 t/ha and vermicompost @ 1 t/ha) and three nitrogen levels (100 kg N/ha, 150 kg N/ha and 200 kg N/ha). Grain and stover yield of maize were significantly higher at 200 kg N/ha (52.01 q/ha and 8.16 t/ha, respectively) over other nitrogen levels. Among the organic sources, row application of poultry manure recorded significantly higher grain and stover yield (53.53 q/ha and 8.24 t/ha). The combination of row application of poultry manure @ 1 t/ha and 200 kg N/ha recorded significantly higher grain yield (57.57 q/ha) over other combinations. The increase in grain yield of maize at row application of poultry manure with 200 kg N/ha was to an extent of 28.59 per cent over no organics. Application of 200 kg N/ha with row application of poultry manure recorded significantly higher N uptake (284.27 kg/ha) by maize crop and available nitrogen in soil after harvest (187.57 kg/ha). Maximum net returns (17679 Rs/ha) were realized by 200 kg N/ha with row application of poultry manure. Maximum B:C ratio (2.45) was noticed in 150 kg N/ha with row application of poultry manure.ennullThesis
