Abstract:
Animal Science (IAAS), Rampur during winter season of 2014/2015 to find out the moisture retention pattern of soil under different tillage practices. There were six treatments consisting of two tillage practices as main plots i.e. conventional agriculture and conservational agriculture; three sub plots with three sowing dates (November 14, November29 and December 14) were arranged in split plot design in three replicates. Wheat variety Vijay was sown and moisture content of the soil was determined by two methods i.e., gravimetric method and gypsum blocks. There was a positive correlation between the two methods whereas the moisture of the soil was influenced by the establishment methods of depth (0-10 cm) at 45, 60 and 75 Days after sowing (DAS). The moisture content of the soil was higher in conservation tillage at reproduction and maturity stages. Conservation agriculture helps to conserve the moisture in the upper depth more significantly than lower depth. Hence, Conservation agriculture provides good soil moisture retentive capacity for wheat productivity in Terai region of Nepal.
