摘要

The experiment was conducted at All India Co-ordianted Research Project for Dry land Agriculture, UAS, GKVK, Bangalore during 1995—2000. The experimental site is situated in Agro-climatic Zone-V of Karnataka State located at 12° 35′ North latitude and 77° 35′ East longitude and at an elevation of 930 m above mean sea level. The soils of the experimental site is red sandy clay loam & are represented by alfisols belongs to Vijayapur series classified as oxic haplustalf with soil depth of > 90 cm, possess good drainage and infiltration rate of 4 cm/hr—6 cm/hr. The soils are slightly acidic in reaction [pH 5—5.5] and CEC of 7—10 meq/100g. The experiment was laid out with using vegetative live barriers (vetiver and nase grass) for inter terrace management practice in an area of 0.6 hectare each with a land slope of 1.5 per cent. All the plots were provided water harvesting structure (Farm ponds with different lining materials) of 180 m~3 capacity at the outlet of the catchment. The studies on runoff and soil loss during 1996—1998 indicated that the highest mean runoff of 6.89 percent and soil loss 2.4 t per hectare under controlled plot as compared to inter terrace live barriers which recorded lower runoff (11.35% to 12.63%) and soil loss (1.4 t/(ha • year) — 1.7 t/(ha • year)). Similarly, the farm pond lined with LDPE with brick frame work continued to record lower total water loss due to seepage loss (62.01 / (m~2 • day)) as compared to unlined pond (136.98 l/(m~2 • day)). However, the farm pond lined with the soil + cement (8:1) recorded the response loss of 109.58 1 per m~2 per day. The stored water in the Farm pond could be used for protective irrigation to transplanted chilli (second crop) resulting 88% to 143% higher yield with a monitory returns of Rs. 28,583 per hectare as compared to other system.
