Effect of sulphur and zinc on growth, yield and quality of summer greengram (Vigna radiata L.) under middle Gujarat condition

Abstract

The field experiment was carried out to study the effect of sulphur and zinc on growth, yield and quality of summer Greengram (Vigna radiata L. Wilezeck) under Middle Gujarat Conditions. The experiment was comprised with twelve treatment combinations of four levels of S (0, 10, 20 and 30 kg S ha-1), and three levels of Zn (0, 1 and 2 kg Zn ha-1) which were replicated three times. The results indicated that application of S @ 30 kg S ha-1 significantly increase in yield attributes thereby increasing seed (1039 kg ha-1) and stover yield (1967 kg ha-1) of green gram over 20 kg S ha-1 (S2), 10 kg S ha-1 (S1) and control (S0). Likewise, Zn application @ 2 kg ha-1 also resulted in the highest seed (1008 kg ha-1) and stover (1883 kg ha-1) yield over 1 kg Zn ha-1 (Zn1) and control (Zn0). The results indicated that application of S @ 30 kg S ha-1 significantly increase in yield attributes No. of branches, seeds per pod and pods per plant of green gram over 20 kg S ha-1 (S2), 10 kg S ha-1 (S1) and control (S0). Likewise, Zn application @ 2 kg ha-1 also resulted in the no. of branches, seeds per pod and pods per plant over 1 kg Zn ha-1 (Zn1) and control (Zn0). The results indicated that application of S @ 30 kg S ha-1 significantly increase in No. of nodules per plant and dry wt. of nodules of green gram over 20 kg S ha-1 (S2), 10 kg S ha-1 (S1) and control (S0). Likewise, Zn application @ 2 kg ha-1 also resulted in the no. of nodules per plant and dry wt. of nodules over 1 kg Zn ha-1 (Zn1) and control (Zn0). In the light of the results obtained from the present investigation, it is concluded that the application of 30 kg S ha-1 and 2 kg Zn ha-1 on loamy sand soil of Anand, deficient in sulphur and zinc increased the yield and protein content in the seeds besides increasing their content in the soil.
