A study was carried out to examine the changes in soil chemical properties and crop yields in a area of Asma village of Valsad district (Gujarat). The result showed that the mean values of soil pH and EC were increased with time. Although, average values of organic carbon, available P and available K were decreased year by year. Also difference between maximum and minimum values of soil pH, EC, organic carbon, available P and available K become larger with time due to greatly different in fertilizer application between farmers. Though the yields of crops were increased with cultivation of hybrid varieties but the changes in soil nutrient status have shown there might be need to improve soil management with application of organic and biofertilisers to sustain the fertility of the soil.

Abstract

A field experiment was conducted during Rabi season in year 2007-2008 on light textured soils of Regional Research Station, Sardarkrushinagar Dantiwada Agricultural University. Results of the experiment revealed that yield attributes like plant height, no. of primary and secondary branches plant^-1, no. of siliqua plant^-1, no. of seeds silique^-1 and test weight were recorded significantly higher with application of 60 kg S ha^-1 (S₄) but it was at par with the 45 kg S ha^-1 (S₃) and 30 kg S ha^-1 (S₂) levels in case of no. of primary and secondary branches plant^-1 as well as found at par with 45 kg S ha^-1 (S₃) for no. of siliqua plant^-1, no. of seeds silique^-1 and test weight. The significantly higher seed yield was recorded with the application of sulphur @ 60 kg ha^-1 (S₄) and higher straw yield was recorded with S fertilization @ 45 kg ha^-1 (S₃) which was at par with 60 kg S ha^-1 (S₄) and 30 kg S ha^-1 (S₂) levels. The per cent increase in seed yield under S₄, S₃, S₂, and S₁ was 45.03, 44.92, 41.10 and 23.08 over control.
