Infiuence of Various Levels of Sulphur on Growth and Yield of Single Cross Hybrid Maize
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 5
Abstract
Evaluation on the effect of sulphur on the growth, yield and nutrient uptake of maize was experimented during Kharifseason, 2013 at College farm, College of Agriculture, Rajendranagar, Hyderabad. This was on the topic, “Influence of varying levels of sulphur on growth yield and nutrient uptake of single cross hybrid maize (Zea mays. L )’’. An experiment was conducted with five different levels of sulphur (S0 : 0 kg ha-1, S1 : 20 kg ha-1, S2 : 40 kg ha-1, S3 : 60 kg ha-1 and S4 : 80 kg ha-1), which were placed in randomized block design with factorial concept replicating thrice. As a result, the yield of grain and stover were recorded significantly to be higher than N1 (180 kg ha-1). It was also evidenced that the per cent increase in grain and stover yield were 4, 3.2 over N1 respectively. When the sulphur levels are increased, the yield of grain and stover were increased in decreased rate but in par with S3 (60 kg ha-1). With S1 (20 kg ha- 1 ), S2 (40 kg ha-1), S3 (60 kg ha-1) and S4 (80 kg ha-1), the increase percent in grain yield was 8.2, 13.8, 23.2 and 20.6 respectively over S0 (0 kg ha-1). It is also observed that the nutrient uptake by grain and stover was significantly higher with N2 (225 kg ha-1) than N1 (180 kg ha-1). Positive effect was shown on the growth and yield of maize by the application of sulphur levels. Similarly, there was a positive effect on nutrient uptake by grain and stover at harvest. Grain and stover showed highest level of nutrient uptake with S3 (60 kg ha-1), which is considerably higher than S2 (40 kg ha-1), S1 (20 kg ha-1) over S0 (0 kg ha-1) and in par with S4 (80 kg ha-1). Records have shown that the treatments with higher application of nitrogen N2 (225kg ha-1) avails higher nitrogen status. When the level of Sulphur is increased, S status of soil is influenced. Potassium and phosphorus availability in soil along with Nitrogen &Sulphur level and sulphur-nitrogen interaction was found to be insignificant.
