EFFECT OF PLANTING METHODS ON GROWTH AND AGROMETEOROLOGICAL INDICES OF RICE
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 55
Abstract
A field experimental trail was carried out in the kharif season 2011 year at Regional Research Station (RRS), CCS Haryana Agricultural University, Kaul, India to evaluation the comparative performance of scented/basmati rice variety (CSR 30) under five different methods of planting viz., machine transplanting under pudlled (M1) and unpuddled conditions (M2), direct seeding under vattar conditions (M3), direct seeding under zero tillage(with residue) (M4), conventional practice (nursery raising) (M5) in a randomised block design with three replications. Among different method of planting the growth indices like the leaf area index, relative growth rate, leaf area duration, , leaf weight ratio, specific leaf area, unit leaf area, leaf relative growth rate, relative leaf growth rate, relative leaf area growth were significantly higher in M1 planting method and relative leaf area expansion rate, and net assimilation rate, leaf area ratio, leaf area portioning factor were higher in M3 planting method. Agrometeorological indices like accumulated growing degree days, accumulated helio-thermal units, accumulated photo thermal units were obtained highest in M3, M2 and M5 planting method and highest radiation use efficiency were obtained in M5 as well as highest radiation use efficiency were obtained in M1 planting method.
