Abstract

A field experiment was conducted on pearlmillet var. GHB-526 in medium black calcareous soils (Vertic Ustocrepts) using fertility gradient approach and fertilizer prescription equation were calculated. The results of follow up trials conducted at different location showed that the economics of fertilizer use based on soil test for achieving maximum yield indicated an additional benefit over general recommended dose at tested grain yield targets of 24, 30 and 36 q ha^-1. The income/cost ratios of the additional produce obtained over recommended dose were 16.79, 4.21 and 3.34 for pearlmillet grain yield at targets of 24, 30 and 36 q ha^-1, respectively.

Keywords

Abstract

The field experiment was conducted on medium black calcareous soils of the Instructional Farm College of Agriculture, JAU, Junagadh during summer season. The results revealed that the significantly higher grain and stover yields, yield attributes as well as quality parameters were obtained with application of N @ 120 kg ha^-1 and K @ 120 kg ha^-1. The grain yield of summer pearlmillet increased to the tune of 49.06 and 37.27 per cent with application of 160 kg N ha^-1 and 120 K₂O ha^-1 as compared to control, respectively. The grain (3536 kg ha^-1) and stover (6793 kg ha^-1) yield of pearlmillet were obtained significantly higher under combined application of N₁₆₀ K₈₀ over control i.e. N₀K₀.

Abstract

District wise picture with regard to changes in available sulphur over a cycle of ten years in the soils of Saurashtra region of Gujarat was studied by collecting 169 surface soil samples (0-15 cm) from tagged cultivated farmer’s field during the year 1990 and 2000. All the district in the year 1990 exhibited high levels of available S but after a span of 10 years different districts registered depletion of available S. Overall, the available S status was declined from 24.4 to 14.5 ppm in soils of Saurashtra region during a span of 10 years.

Keywords

Available S Status, Depletion of Available S, Soils of Saurashtra.
