Abstract

A lysimeter experiment was conducted during Rabi season of 2004 and 2005 to evaluate five varieties of chick pea with five salinity levels (ECiw-0.5, 2.0, 4.0, 6.0 and 8.0 dSm^-1) at Junagadh Agricultural University, Junagadh. The grain and fodder yields decreased significantly with an increasing in the salinity of irrigation water during both the year as well as in pooled. Among the varieties of chick pea, variety GG-4 gave significantly the highest grain and fodder yield in all the salinity levels of irrigation water. The variety GG-4 recorded highest mean grain yield (17.38 g), mean salinity index (71.2%), minimum Na/K ratio (0.34) in fodder and minimum yield reduction (46.2) at high salinity levels.

Abstract

A field experiment was carried out in medium black calcareous clayey soils (Typic Ustocrepts) during Kharif season of 2006 to 2008 at Sagadividi Research Station, Junagadh Agricultural University, Junagadh, with five treatments viz.,T₁-Urea.,T₂-Urea+Calcium chloride (Balance CAN), T₃-Urea+wetable sulphur (Balance AS),T₄-Calcium ammonium nitrate (CAN) and T₅-Ammonium sulphate (AS) using RBD design with four replications. Nitrogen was applied @160 kg ha^-1 in three equal splits at basal, 30 and 60 days after sowing (DAS) from each source of treatments. The results showed that different N source treatments did not produced any significant effect on growth, yields and quality parameters of cotton crops but soil available sulphure was influenced after harvest of crop. As per economic point of view, for fertilization of cotton crop, urea fertilizer found cheaper as compare to other nitrogen sources like CAN and Ammonium sulphate.
