CORRELATION STUDY OF GROWTH, DEVELOPMENT AND YIELD WITH AGROMETEOROLOGICAL INDICES UNDER DIFFERENT PLANTING METHOD OF RICE
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
An field experimental trail was carried out in the kharif season of 2011 at Chaudhary Charan Singh Haryana Agricultural University, Regional Research Station, Kaul, India to study the comparative performance of scented/basmati rice (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. The growth indices like LAI, CGR, RGR, NAR, LAD, LWR, SLA, SLW, ULR, LRGR, LAPF and agrometeorological indices i.e. AGDD, AHTU, APTU, RUE and HUE showed significantly positive correlation with yield and yield attributes whereas LAR, RLGR, RLAGR ,RLAER ,AGDD, AHTU and APTU was negatively correlated with yield and yield attributes at different vegetative growth phase (DAS).
