| Abstract:
Five soil working techniques viz. T1- traditional basin, T2 –basin with 15 cm thick grass mulch, T3-V-ditch (Negarin), T4 –trench system, T5 – crescent bund with open catchment pits were employed to conserve the soil moisture at three soil depths (0-15, 15-30, 30-45 cm) under two plant spacings of 3x3 and 4x3m. Among different soil working techniques used, T5 – crescent bund with open catchment pits happened to store maximum soil moisture content of 13.62, 15.18 per cent at 0-15 cm soil depth, 14.04,16.23 per cent at 15-30 cm soil depth and 14.44, 17.29 per cent at 30-45 cm soil depth during the years 2001 and 2002, respectively. The yield per plant and per hectare was also recorded highest in crescent bund with open catchment pits due to high moisture availability. The plants spaced at 4x3 m produced larger fruits than 3x3 m spacing. However, 3x3 m spacing produced higher yield of small sized fruits due to accommodation of more number of plants per hectare (1112 plants/ha) in comparison to 4x3 m plant spacing (834 plants/ha). | |
