Abstract
The study was undertaken to evaluate the impact of various conservation technologies for conservation of soil moisture at different depths and distances from soil and water conservation measures in the village Kandi. Village under study is located in dry land area of mountaineous eco-system in Akhnoor tehsil of Jammu district. The conservation technologies adopted during the study were; Contour bund cum trench (T1), Contour bund (T2), Contour trench (T3) and Control plot (T4).
Soil sample were taken for moisture estimation from the all conservation measures at three depths D1 (0-15 cm), D2 (15 -30 cm) and D3 (30 – 45 cm) each at three distances from the conservation measures L1 (1 m), L2 (2 m) and L3 (3 m) on fortnightly basis during the growth period of wheat crop from October 2020- April 2021. In addition, bulk density analysis and infiltration rate was also recorded at three instants i.e. before rainfall, after rainfall and at the time of harvest of crop. Moisture distribution pattern w.r.t. depth and distance from each conservation measures was evaluated. Impact of enhanced moisture regime within the soil mass was recorded on crop productivity of wheat.
The moisture content was found maximum in T1 in all months of crop growth period with the maximum value i.e. 11.52 % in the month of December. T4showed lowest moisture content in all months and least with the value of 3.37% during the 3rd week of November. The moisture content showed increasing trend before the rainfall and decreasing trend after the rainfall with respect to lower depths for all treatments. Increasing trend of moisture content was found w.r.t. distance from the conservation measures in T1 , T3, T2 w.r.t. T4. The infiltration rate and bulk density was higher before the rainfall and lower after the rainfall.
The crop productivity was found with a value of 20.5, 18.7, 16.5 and 14.3 q/ha in T1, T2, T3 and T4 respectively. The crop productivity was found higher in the T¬1 by 43.35%, 30.76% for the treatment T3, 15.38% for the treatment T2 in comparison to T4.
