ABSTRACT
A field experiment was carried out to study the effect of nitrogen levels (68,90,135& 180 kg ha-1) in combination with foliar nutrition on growth and yield of machine transplanted rice variety MTU 1061.The experiment was conducted during kharif 2013 under canal irrigation at Andhra Pradesh Rice Research Institute & Regional Agricultural Research Station – Maruteru. The experiment was laid out in a split plot design with four nitrogen levels in main plots and foliar feeding treatments in sub-plots and replicated thrice. The experimental results revealed that application of 150% RDN (135 kg/ha) registered maximum plant height, tillers m-2, panicle length, No of grains panicle-1, grain yield, and straw yield over 100% RDN. Additional nutrition through foliar feeding at panicle initiation with 1% 19:19:19 improved yield attributes, grain and straw yields marginally over 2% DAP or 2% KNO3. The interaction between nitrogen levels & foliar feeding treatments was found to be non-significant.
Key words :
Foliar nutrition, Growth & yield attributes, Machine transplanted rice, Nitrogen levels.
