Effect of agronomic and weed management practices on crop growth rate and relative growth rate of direct seeded rice under agro climatic condition of eastern Uttar Pradesh

A field experiment was carried out in the year 2014 and 2015 at experimental of Banaras Hindu University, Varanasi, Uttar Pradesh to evaluate effect agronomic weed management practices on crop growth rate (CGR) relative (RGR) direct seeded rice. Twenty-four treatment combinations consisting two mulching viz. no mulch live (brown manuring with Sesbania) nitrogen levels (120 kg ha-1, 150 ha-1  180 ha-1 ) main plot four weedy check, hand weeding 20 40 DAS; azimsulfuron @ 30 g + bispyribac-sodium 25 10-15 pendimethalin 1 1-3 DAS fb 15-20 were allocated sub plots. It observed that CGR RGR significantly higher under brown Sesbania N level. Under various practices, 1kgha-1 fb bispyribac-sodium 25g recorded parameters for both years.
