Abstract:
Experimental studies on effect of weed management practices in castor (Ricinus communis L.) was conducted at Agricultural College Farm, Bapatla during kharif, 2020 on clay soils. The results indicated that significantly the plant height, drymatter accumulation, seed and stalk yield were registered under the treatment hand weeding at 20 and 40 DAS (T₂), which was however on a par with the treatment supplied pre-emergence application of alachlor @ 1.5 kg a.i ha^-1 fb chlorimuron @ 10 g + propaquizafop @ 63 g a.i ha^-1 as PoE at 30 DAS (T₉) as well as pre-emergence application of alachlor @ 1.5 kg a.i ha^-1 fb halosulfuron @ 67.5 g a.i + propaquizafop @ 63 g a.i ha^-1 as PoE at 30 DAS (T₁₀).
