Abstract

The role of nutrients is profound in playing a vital role in the quality of soybean crops and as such its supplementation to the crop is pertinent for increased productivity. In relation to this, a field experiment was conducted at the Experimental Research Farm of School and Agricultural Sciences and Rural Development (SASRD), Nagaland University, during the kharif season of 2017 and 2018 to study the effect of different levels of sulphur and zinc fertilization on the quality and economics of soybean (Glycine max L. Merrill) under Nagaland condition. The experiment was laid out in a Factorial Randomized Block Design (RBD) with 15 treatments combinations viz., sulphur @ 0 kg ha-1, 20 kg ha-1, 40 kg ha-1, zinc @ 0 kg ha-1, 5 kg ha-1, 10 kg ha-1, 15 kg ha-1 and 20 kg ha-1 replicated thrice. The results from the two years study showed that the oil and protein content in the crop were significantly influenced by the treatment combination of S20Zn20 as compared to the other levels of treatments. A higher oil and protein content were observed with the application of 20 kg S ha-1 which was comparatively at par with the application of 40 kg S ha-1 and superior over control while 20 kg Zn ha-1 fertilization recorded significantly the highest oil and protein content followed by the application of 15 kg Zn ha-1. In terms of the economics of the treatments, S20Zn20 gave the highest gross returns, net returns and B:C ratio followed by S20Zn15 for both the years and pooled. Thus, based on the results of the two years experiment, the treatment combinations of S20Zn20 was found to be a suitable fertilizer dosage for soybean.

Conclusion

Based on the results of the two years experiment, the treatment combination of 20 kg S ha-1 and 20 kg Zn ha-1 was found to be a suitable fertilizer dosage for soybean compared to the other treatments. The quality parameter of soybean was seen to be significantly influenced by the application of sulphur and zinc at 20 kg S ha-1 and 20 kg Zn ha-1. The application of S20Zn20 also led to good results recording the highest gross returns, net returns and B:C ratio.
