Not AvailableAgroforestry landuses fulfil both productive and service functions. The main productive outputs are foodgrains, fuelwood and folder but the most important service function is soil conversion. It means not only control of erosion but also includes the maintenance as well as improvement of soil organic, physical and nutirent status(Lyndgren and Nair, 1985

Not AvailableTHE AUTHORS SUGGEST EFFECTIVE METHODS OF CONTROLLING DIFFERENT WEEDS GROWN ALONG WITH WHEAT CROP WHICH RESULT IN LOW YIELDS. MODIFICATION IN CROP ROTATION, FIELD PREPARATION AND SOWING , TILLAGE AND USE OF PROPER WEEDICIDES ARE DISCUSSED.Not Availabl

Not AvailableTHE AUTHORS BRING OUT THAT BY ADOPTION OF IMPROVED METHODS OF WEED CONTROL BY APPLICATION OF CHEMICAL WEEDICIDES AND ALSO BY BIOLOGICAL MEANS, THE YIELDS OF MAIZE AND PADDY CAN BE INCREASED APPRECIABLY IN DOON VALLEY, WHERE DUE TO HIGH RAINFALL, WEEDS GROW ABUNDANTLY IN BOTH THESE CROPS.Not Availabl

Not AvailableRESULTS OF A STUDY CONDUCTED AT DEHRADUN DURING 1986-91 ON RUNOFF AND SOIL LOSS ON 1.86 X 22.13 m RUNOFF PLOTS AT 8% SLOPE HAVE BEEN PRESENTED. METHODOLOGY TO ESTIMATE USLE- PARAMETERS IS DESCRIBED. THE AVERAGE RAINFALL EROSION INDEX ( R) FOR DEHRADUN IS 1048 AND SOIL ERODIBILITY FACTOR (K) IS 124 kg/ha /unit OF R. COWPEA COVER EFFECTIVELY REDUCED RUNOFF AND SOIL LOSS BY PROVIDING COVER NEAR THE LAND SURFACE AND AT EARLY STAGES OF CROP GROWTH. SIMILARLY , MANDUA AND JHINGORA , THE NATIVE HILL REGION CROPS, ARE EFFICIENT IN RESPECT OF SOIL AND WATER CONSERVATION. THE CROP MANAGEMENT FACTOR 'C' FOR COWPEA WAS 0.31 AND FOR MANDUA AND JHINGORA WAS 0.17 AND 0.18 , RESPECTIVELY. , WHICH IS CLOSE TO THE 'C' FACTOR FOR GRASS SPECIES. THE INFORMATION ON CANOPY OF DIFFERENT CROPS AND THEIR COMBINATION IS ALSO PRESENTED.Not Availabl
