Abstract:

A field experiment was conducted during Kharif, 2017 at College Farm, College of Agriculture, Rajendranagar, Hyderabad to compute the optimum dose and source of sulphur in maize and to evaluate the impact of sulphur on growth, yield attributes and yield of maize. The experiment was carried out with three different sources of sulphur (Gypsum, Ammonium Sulphate and Bentonite Sulphur) and three levels (S @ 40 kg ha-1, S @ 60 kg ha-1 and S @80 kg ha-1) and one source as urea, DAP and MOP and another source as urea, SSP and MOP comprising of eleven treatment combinations which were laid out in randomized block design and replicated thrice. In all the treatments nitrogen was applied in two split doses 50% as basal and 50% as top dressing at 45 DAS and entire dose of phosphorous, potassium and sulphur were applied as basal. Treatment T1 was application of recommended dose of fertilizer i.e., N-P2O5-K2O-S @ 200-60-50-60 kg ha-1 without sulphur. Treatment T2 was application of recommended dose of fertilizer through Urea, SSP and MOP. T3 was T1 + application of sulphur @ 40 kg ha-1 through gypsum; T4 was T1+ application of sulphur @ 60 kg ha-1 through gypsum; T5 was T1 + application of sulphur @ 80 kg ha-1 through gypsum. T6 was T1 + application of sulphur @ 40 kg ha-1 through ammonium sulphate. T7 was T1 + application of sulphur @ 60 kg ha-1 through ammonium sulphate. T8 was T1 + application of sulphur @ 80 kg ha-1 through ammonium sulphate. T9 was T1+ application of sulphur @ 40 kg ha-1 through bentonite sulphur. T10 was T1+ application of sulphur @ 60 kg ha-1 through bentonite sulphur. T10 was T1 + application of sulphur @ 80 kg ha-1 through bentonite sulphur. Highest grain (5596 kg ha-1) and stover yield (6995 kg ha-1) was recorded by treatment T10 (S@60 kg ha-1 through bentonite sulphur) followed by treatment T2 (5581 and 6976 kg ha-1) S@40 kg ha-1 through urea, SSP and DAP. Highest gross returns were recorded by T10 (Rs. 80139 ha-1) followed by T2 (Rs. 78623 ha-1) though highest B: C ratio was recorded by T2 because of higher cost of bentonite sulphur fertilizer.
