Influence of phosphorus and sulphur levels on nutrient content uptake and quality of fenugreek

Abstract

Background: A field experiment was conducted at Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh during rabi 2016-17 to study the Effect of phosphorus and sulphur fertilization on growth, yield and quality of fenugreek (Trigonella foenum-graecum L.). Method: The experiment was laid out in factorial randomized block design with three replications. Treatment combinations includes three levels of phosphorus (0, 20 and 40 kg P2O5 ha-1) and three levels of sulphur (0, 20 and 40 kg S ha-1). Result: Among the different levels of phosphorus, application of 40 kg P2O5 ha-1 recorded significantly higher seed, stover and biological yield. Application of 40 kg P2O5 ha-1 recorded significantly higher protein yield.N, K and S content in seed and stover was found non-significant, while phosphorus content in seed (0.54%) and stover (0.29%) was significant under the application of 40 kg P2O5 ha-1, it also recorded significantly higher uptake of NPK and S by seed and stover. Significantly higher seed, stover and biological yield were recorded under application of 40 kg S ha-1. Application of 40 kg S ha-1 recorded significantly higher protein yield, S content in seed and stover and maximum uptake of P and S by stover.
