WHY UPLANDS ? • Intensive agriculture area is limited to jhola (low) lands • Perennial flow of water restricts them to monoculture of rice • Invites good scope of agriculture area expansion • Major source of soil loss and runoff

IRC-2008
PROBLEMS OF UPLANDS • Undulating topography • Poor selection of crops & faulty mgt. practices • Erratic rainfall of the region • Lack of information regarding choice of crops and SWC practices RC-Koraput

TREATMENTS • Main plots-----slope-2 & 5% • Sub plots------crop combinations • Ragi+GN------4:6, 4:8, 6:8, 8:10 • Upland rice+ BG-4:6, 4:8, 6:8, 8:10 • Pure crops as control • Design ------split plot • Total treatment combinations----60

OBJECTIVES 1. To access the biophysical performance and yield of different strip crop combinations on varying slopes of uplands 2. To determine optimum width of strip for resource conservation on different slopes 3. To estimate run off & soil losses under different strip crop combinations on varying slopes 4. To estimate the impact of strip crop on soil nutrient losses and soil health RC-Koraput

OBSERVATIONS • Biophysical measures, yield attributes and yield of crops • Soil loss, runoff and nutrient loss estimation • Soil fertility status OC,NPK, EC, Ph, microbial activity • Soil physical parameters-aggregate determination, water holding capacity, infiltration capacity
