Dry matter production, yield attributes, yield and quality of clusterbean [Cyamopsis tetragonoloba(L.) taub.] as influenced by nitrogen and zinc application

Abstract

A field experiment was conducted during early kharif of 2008 on sandy clay loam soils to study the effect of nitrogen and zinc on yield and quality of guar [Cyamopsis tetragonoloba (L.) Taub.]. The experiment was laid out in a split-plot design and replicated thrice. The treatments consisted of three nitrogen levels viz., 20, 30 and 40 Kg N ha -1 in main plots and four zinc management viz., 0.5% ZnSO 4 spray at 25 days after sowing (DAS), 45 DAS, 0.5 % ZnSO 4 spray at 25 and 45 DAS including soil basal application of 20 Kg ZnSO 4 ha -1 . Significantly highest dry matter production was registered with 40 Kg N ha -1 , while it was the lowest with 20 Kg N ha -1 . Yield attributes and seed and stalk yield were the highest with 30 Kg N ha -1 . Among the zinc management practices 0.5 % ZnSO 4 spray at 25 and 45 DAS resulted in highest seed and stalk yield. With regard to quality parameters, protein content was found to be the highest with 40 Kg N ha -1 , which was however, comparable with 30 Kg N ha -1 . The highest protein content was recorded with 0.5 % ZnSO 4 spray at 25 and 45 DAS while it was the lowest with 20 Kg ZnSO 4 ha -1 .

Effect of Soil and Foliar Application of Zinc and Iron on Yield, Nutrient Content and Quality of Summer Mungbean

“…Similarly higher yield attributes and yield were noticed with the combined foliar spray of micro nutrients with zinc attributed to optimum availability of nutrients for luxurious crop growth and efficient partitioning of assimilates from source to sink. Higher stover yield of mungbean might be due to direct influence of zinc on auxin production which in turn enhanced the elongation processes of plant development" [2,3,4,5,6,7,8,9]. Similar results higher yield and quality on maize crop was given by Satdev et al, [10], and Peddapuli et al [11] in maize.…”
