Abstract:
The field experiment entitled “Performance of planting patterns and weed control treatments on growth of spring season Green gram (Vigna radiata L.) and associated weedswas conducted during the spring season on the research farm of the School of Agriculture, Lovely Professional University, Phagwara (Punjab).Fifteen treatments combination of three main plot treatments (planting pattern) viz., M1: Row sowing, M2: Cross sowing, and M3: Bed sowing and five weed control treatments in subplots viz., T1: Stomp 30 EC (pendimethalin 0.75 kg /ha), pre em, T2: Stomp 30 EC (pendimethalin 0.5 kg /ha), pre em. fb one H.W, T3: Parimaze 10 SC (imazethapyr 50 gm /ha), post em, T4: One hand weeding, T5: Unweeded (control) were kept. The experiment was laid out in Split-Plot Design with four replications. Among planting patterns total weed count and dry matter was observed to be at par among flat planting and bed planting and both these techniques produced significantly higher weed count and their dry matter than cross sowin. Significantly low weed count and dry matter accumulation by weeds was obtained under Stomp 30 EC (pendimethalin 0.5 kg /ha), pre em. fb one H.W, one hand weeding, Stomp 30 EC (pendimethalin 0.75 kg /ha), pre em and Parimaze 10 SC (imazethapyr 50 gm /ha), post em treatments.as compared to unweeded (control).The plant height was significantly more under bed sowing than cross sowing and row sowing. Stomp 30 EC (pendimethalin 0.5 kg /ha), pre em. fb one H.W recorded the significantly highest plant height among all weed control treatments. The dry matter accumulation by plant was found to be more in Stomp 30 EC (pendimethalin 0.5 kg /ha), pre em. fb one H.W which was significantly better than one hand weeding, Stomp 30 EC (pendimethalin 0.75 kg /ha), pre em, Parimaze 10 SC (imazethapyr 50 gm /ha), post em and unweeded (control) treatments. Significantly higher seed yield was recorded under the cross sowing (15.67 q/ha) method of planting pattern than bed (14.15q/ha) and row sowing method (13.88 q/ha). The yield under cross sowing was 10% and 11% percent higher than bed sowing and flat sowing techniques respectively. In different weed control treatments, the higher seed yield was recorded under Stomp 30 EC (pendimethalin 0.5 kg /ha), pre em. fb one H.W(16.85 q/ha) and lowest seed yield was observed under unweeded control(10.28 q/ha) which was significantly less than other weed control treatments. The percentage increase in Stomp 30 EC (pendimethalin 0.50 kg /ha), pre em, f.b. one HW, one hand weeding, Stomp 30 EC (pendimethalin 0.75 kg /ha), and pre em. Parimaze 10 SC (imazethapyr 50 gm /ha), post em, was 39%, 34.82%, 33.6%, 28.90%, more than unweeded control respectively.
