Abstract

Field study in Rajasthan, India was undertaken to find out the effect of mulches on moisture and thermal regime of Jodhpur loamy sand soil and on the production of pearl millet. Mean maximum soil temperature was higher under polyethylene and lower under millet husk mulch in comparison to control (without mulch). Soil temperature at 5 cm depth was higher by 1 to 3 deg C under polyethylene and lower by 2 to 4 deg C under millet husk. A significant decrease in temperature with depth was noticed under polyethylene while there were minor changes under millet husk. Maximum grain yield of pearl millet was obtained from soil under polyethylene (29.0 q/ha) followed by millet husk (23.0 q/ha) and control (17.4 q/ha) with water use efficiency of 10.4, 8.5 and 6.0 kg/mm/ha, respectively.ADDITIONAL ABSTRACT:In trials with pearl millet, mulching with (a) white polyethylene film or 6 t bajra [Pennisetum americanum] husk/ha increased soil m.c. The soil temp. was increased with (a) and decreased with (b). Grain yields with (a) and (b) and without mulch were 2.9, 2.3 and 1.74 t/ha and water use efficiency was 10.4, 8.5 and 6 kg/mm, resp
