A field experiment was laid out in Randomized Block Design consisted of eight treatments with three replication to find out suitable weed management in summer mung bean (Vigna radiata) under zero tillage condition during summer season of 2019-20 under irrigated condition at ICAR-NDRI, Karnal, Haryana. To evaluate the quality of fodder in terms of, organic matter, total ash, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, acid detergent lignin. The result showed that weed free (T₂) plots recorded higher (P<0.05) green and dry fodder yield, followed by Shaked (Propaquizafop + Imezathyper) (T₆) and Pendimethalin fb one HW at 20 days after showing (T₄), T₂, T₆ and T₄ recorded higher green fodder yield by 59.32, 40.12 and 39.86% over weedy check (T₁). Among weed control treatments, T₄ recorded significantly higher crude protein, ether extract and dry matter content was at par on T₆ and significantly (P<0.05) superior over T₁ Same trends were also observed in CP, EE and dry matter yield (q/ha). The treatments T₄ and T₆ also enhanced fodder quality by reducing neutral detergent fiber, acid detergent fiber and acid detergent lignin content over weedy check. Thus, application of Shaked (Propaquizafop + Imezathyper) at2 l/ha at 20 days post-sowing would increase yield and quality of summer mung bean fodder under zero tillage condition.

Background: Optimum crop growth and yield is result of interlinking of several factors. In semi- tropical soil in central plateau and hills zone are deficit in organic carbon and NPK content; therefore inadequate fertilization may leads to pure quality and also lower crop productive capacity of soil. For the maintenance of sustainable and productive production, maintaining soil health is a critical factor. Under low fertility levels, mungbean gives low seed yield. Potassium humate, nitrogen and phosphorus (RDF) application may be increase yield of mungbean in this zone. Method: A field experiment was conducted to study, “Nodulation, yield attributes and yield of mungbean [Vigna radiata (L.)] influenced by different level of potassium humate and fertility. The experiment was carried out in factorial randomized block design with three replications and sixteen treatment combination. Result: Result showed that total number of root nodules, effective nodules, fresh and dry weight of root nodules, leghaemoglobin, nodule index, no. of pods/plant, no. of seeds/pod, test weight, seed and straw yield were observed significantly higher with application of potassium humate @ 4.5 kg/ha. Among different fertility level, the application of 100% RDF significantly increased the total number of root nodules and effective nodules, fresh and dry weight of root nodules, leghaemoglobin, nodule index, no. of pods/plant, no. of seeds/pod and test weight, seed and straw yield. With combined application of potassium humate @ 3.0 kg/ha + 75% RDF significantly higher no. effective nodules, dry weight of root nodules and seed yield were observed, as well as saving of 25% RDF and 1.5 kg potassium humate were also observed.
