| Abstract: |
Field experiments were conducted during the winter seasons of the year 2007/08 and 2008/09 on an acid soils of the NMRP research farm. The objective of the study was to identify the appropriate doses of sulphur and agricultural lime on maize crop and their recommendation for its increased productivity. Three levels of sulphur (0, 20 and 40 kg S ha-1) and 4 levels of agricultural lime (0, 2.5, 3.75 and 5 t ha-1) were used in the study. A factorial RCB design with 3 replications was employed in the experiment. The variety used was Deutee and the plot size was 22.5 sq.m (5 m x 4.5 m). The crop was fertilized with 120:60:40 kg ha-1 of N, P2O5 and K2O, and 10 t ha-1 of compost, respectively. The highest grain yield (6.86 t ha-1) was recorded in the 1st year (2007/08) when 5 t ha-1 of agricultural lime and 40 kg of sulphur (S) was applied. In the following year (2008/09), the mean effect of S levels indicated a sharp response at only 20 kg ha-1 which produced an yield of 7.84 t of grains ha-1., whereas the mean effect of lime use revealed only the production of 7.55 t ha-1 of grains in the same year when the crop was supplied with 2.5 t ha-1 of agricultural lime. It is noticed that the response of sulphur and agricultural lime on maize grain production was found to be significant in both of the years. Farmers are suggested to apply at least 20 kg of sulpher along with 2.5 t ha-1 of agricultural lime on maize for increased grain production.
