Abstract

Aims: To study the effect of weed management practices on nutrient content and their uptake by green gram (Vigna radiata L.).

Study design: Randomized block design.

Place and duration of study: One-year field experiment at Research Farm, School of Agriculture, Abhilashi University, Chail Chowk, Mandi, (H.P.).

Methodology: The experiment was conducted with three replications and ten treatments viz.- T1 = (Weedy check), T2= (Weed free), T3 = (Hand weeding at 20 & 35 DAS), T4 = [Quizalofop-p-ethyl @ 35.50 g a.i. ha-1 (PoE) at 20 DAS], T5 = [Quizalofop-p-ethyl @ 75.00 g a.i. ha-1 (PoE) 20 DAS], T6 = [Pendimethalin @ 1.00 kg a.i. ha-1 (PE)], T7 = [Pendimethalin @ 1.50 kg a.i. ha-1 (PE)], T8 = [Imazethapyr @ 25.00 g a.i. ha-1 (PoE) at 20 DAS], T9 = [Imazethapyr @ 40.00 g a.i. ha-1 (PoE) at 20 DAS] and T10 = [Pendimethalin @ 1.00 kg a.i. ha-1 (PE) + Imazethapyr @ 75.00 g a.i. ha-1 (PoE) at 20 DAS].

Result: Different weed management practices showed non-significant effect on nitrogen, phosphorus and potassium content in grains and straw of the green gram crop, while, the highest content of these nutrients were noted in treatment T2. The application of treatment T2 recorded the significantly maximum uptake of nitrogen, phosphorus and potassium uptake by grains, straw and total uptake by green gram crop, which was statistically at par with treatment T3 and T10. Whereas, the minimum content of nitrogen, phosphorus and potassium along with their uptake by green gram crop was found under treatment T1.

Conclusion: This field study revealed that various weed management practices did not affected the content of nutrients significantly, however, weed management practices significantly affected the nutrient uptake by grains, straw and total uptake by green gram crop.
