Studies on Effect of Zinc Application on Quality and Yield of Soybean (Glycine max L.) under Typic Haplustepts Soil
Abstract
A field experiment was conducted at the Instructional Farm (Agronomy), Rajasthan College of Agriculture, Udaipur, Rajasthan during the kharif season of 2016 and 2017 using randomized block design with four replications to study the influence of soil applied zinc on yield and quality of soybean (Glycine max L.) under Typic Haplustepts soil of sub-humid southern plain and aravalli hills region of Rajasthan. The treatments consisted of five levels of zinc viz., zero (control), 3 kg Zn ha -1 , 4 kg Zn ha -1 , 5 kg Zn ha -1 and 6 kg Zn ha -1 with four replications. Results revealed that significantly (P=0.05) maximum seed, haulm and biological yield, and oil and protein content were recorded with the application of zinc 6 kg ha -1 along with the recommended dose of fertilizer (NPK) during the year 2016 & 2017 and on pooled basis. However, the increase was observed significant upto 5 kg Zn ha -1 during both the years as well as on pooled basis but found statistically at par with 6 kg Zn ha -1 . The application of recommended dose of fertilizer along with combined application of Zn @ 5 kg ha -1 offered the best combination in realizing maximum yield and quality content of soybean.
