Correlation between yield and yield attributing traits in Soybean (Glycine max (L.) Merrill)

Abstract

Micronutrient deficiencies are not only hampering crop productivity but also deteriorating fruit quality. The present investigation was undertaken with the main objective to study the effect of soil application of zinc in tomato (Solanum lycopersicum L.) @ 0, 5, 10, 15 and 20 kg ZnSO4 ha-1) on the growth and quality parameters in greenhouse conditions at UAS (B), Bangalore, Karnataka. The experiment was conducted in Factorial completely randomized design (FCRD) with three replication and 15 locations with varied zinc fertility levels. Zinc application increased the plant growth and quality parameters. Among the all treatments maximum plant growth and quality parameters were achieved by the Zn application at 20 kg ZnSO4 ha-1 along with RDF and the lowest performance was recorded in the control treatment. The results of this study suggest that soil application of zinc at 20 kg ZnSO4 ha-1 along with RDF in all the zinc fertility levels of the soils significantly increased plant height, chlorophyll, TSS, Vitamin C, lycopene and Titra table acidity.
