Abstract

An experiment comprising six soil amendments (Control, FYM at 25 t/ha, Gypsum and Pyrites each at 25 and 50% GR) in combination with two sources of phosphorus (DAP and SSP) with their two methods of application (broadcast and drilling) was carried out on loamy sand saline-sodic soils during 1983-84 and 1984-85. Incorporation of soil amendments significantly increased the growth and biological yield of wheat. The plant height at harvest, number of tillers/m row length and dry matter yield almost at all the growth stages were more under gypsum at 50% GR and the lowest being under control. Similar trend was also observed for the biological yield. Sources of phosphorus as well as their methods of application, however, did not bring any significant impact on growth characters almost at all the growth stages.
