Impact of Zinc and Thiourea Application on Growth and Yield of Summer Green Gram (Vigna radiata L.)

Aims: To find out the Impact of zinc and thiourea application on growth and yield of summer green gram (Vigna radiata L.).

Study Design: The experiment was laid out in Randomized Block Design (factorial concepts) with three replications.

Place and Duration of Study: A field experiment was conducted during summer season of 2020 at Agronomy Instructional Farm, SDAU, Dantiwada (Gujarat). The soil of experimental plot was loamy sand in texture.

Methodology: The experiment comprising three levels of zinc (1.5, 3.0 and 4.5 kg ha-1) and five treatments of thiourea application (control (no spray), seed soaking with thiourea @ 500 ppm, foliar spray of thiourea @ 500 ppm at 30 DAS, foliar spray of thiourea @ 500 ppm at 45 DAS and foliar spray of thiourea @ 500 ppm at 30 and 45 DAS).

Results: Almost all the growth and yield attributes as well as yield were significantly influenced due to various treatments. The plant height (47.02 cm and 46.60 cm, respectively), total number of pods plant-1 (15.92 and 19.82, respectively) and number of seeds pod-1 (7.91 and 8.26, respectively) and seed yield and stover yield were also found significantly higher in the application of either 4.5 kg Zn ha-1 or foliar sprays of thiourea @ 500 ppm at 30 and 45 DAS.

Conclusion: On the basis of experimental results, it can be concluded that to obtain higher yield of green gram crop responds positively to the application of zinc and thiourea with enhancement in the agronomical performance and productivity.
