Not AvailablePRESENTS RESULTS OF A STUDY IN WHICH THE EFFECT OF FOUR RATES OF NITROGEN FERTILIZER ( 0,50, 100 AND 150 kg/ha) WITH AND WITHOUT GREEN MANURING ( LEUCAENA LEUCEPHALA) ON NUTRIENT UPTAKE, FERTILITY BUILD-UP AND WHEAT YIELD WAS INVESTIGATED. LEUCAENA LEAVES ( GREEN LEAVES+TENDER TWIGS) INCORPORATED IN RED SOIL ( PARWA) AS GREEN LEAF MANURING SIGNIFICANTLY RAISED THE YIELD OF BOTH GRAIN AND STRAW. HIGHEST GRAIN PRODUCTION AS RECORDED WHEN GREEN LEAF MANURING ENHANCED THE UPTAKE TO NUTRIENTS( Zn, N AND P) AND NITROGEN USE EFFICIENCY AT DIFFERENT RATES OF N APPLIED. THE STATUS OF ORGANIC CARBON AND AVAILABLE NUTRIENTS ( ZN,N AND P) WAS ALSO INCREASED IN PRESENCE OF GREEN LEAF MANURING. APPLICATION OF 50 kg/ha ( UREA-N) ALONG WITH LEUCAENA LEAVES RESULTED IN HIGHER GRAIN PRODUCTION THAN THAT OBTAINED BY THE APPLICATION OF 150 kg N/ha . THIS CLEARLY INDICATED THAT FOR FERTILIZING WHEAT AS MUCH AS 100 kg OF N /ha COULD BE SUBSITUTED THROUGH LEUCAENA LEAVES.Not Availabl

Not AvailableSUITABLE AGRO- TECHNIQUES AS WELL AS SOIL CONSERVATION MEASURES FOR RAVINE REGIONS IN UTTAR PRADESH HAVE BEEN DEALT WITH IN THE PAPER . WATER HARVESTING / MOISTURE CONSERVATION PRACTICES SUCH AS LAND MODIFICATION, SURFACE MULCHING AND COVER CROPS WERE FOUND EFFECTIVE IN EROSION CONTROL AND IN IMPROVING THE PRODUCTION OF CROPS. MECHANICAL MEASURES LIKE LAND LEVELLING AND CONTOUR BUNDING HAS GREAT PROMISE IN EROSION CONTROL AND MOISTURE CONSERVATION. INCLUSION OF PULSES AND OILSEED CROPS IN SOIL AND WATER CONSERVATION PROGRAMME HAS A DEFINITE ADVANTAGE . USE OF HARVESTED RUNOFF WATER FOR PRE- SOWING IRRIGATION AND IRRIGATIONS AT BRANCHING AND FLOWERING IN MUSTARD GAVE BETTER RETURNS.

Not AvailableEIGHT REPRESENTATIVE PEDONS FROM FOUR SOIL SERIES VIZ RAKAR AND PARWA ( REDSOILS). KABAR AND MAR ( BLACK SOILS) IN THE RESEARCH FARM AREA ( 190.92 ha) AT DATIA , DEVELOPED OVER VINDHYAN RANGES OF ROCKS , SEMI- ARID CLIMATE REPRESENTING TYPICAL FEATURES OF BUNDELKHAND SOILS WERE INVESTIGATED FOR THEIR PHYSICO- CHEMICAL PROPERTIES. THE SOILS WERE NEARLY NEUTRAL TO ALKALINE IN NATURE WITH PH VALUE RANGING FROM 7.1 TO 8.1. CALCIUM WAS THE DOMINANT CATION ON EXCHANGE COMPLEX. THE TEXTURES WERE SANDY AND SANDY LOAM IN RAKAR AND PARWA WHILE SILTY CLAY LOAM AND CLAY LOAM TEXTURE WERE ENCOUNTERED IN KABAR AND MAR, RESPECTIVELY. S REGARDS FERTILITY STATUS, THE BLACK SOILS WERE RICHER IN ORGANIC CARBON AND AVAILABLE NPK THAN THE RED SOILS. COARSE GRAINED ( 72% SAND) RED SOILS ARE SHALLOW IN DEPTH, RESTRICT THE LEVELLING WORK AND ALSO LIMIT THE FEEDING ZONE FOR ROOTS OF CROPS DUE TO HARD AND IMPERVIOUS LAYER IN SUB- COLLAPSE ON EXPOSURE TO RAIN DROP IMPACT. SUITABILITY OF SOIL TYPES FOR DIFFERENT CROPS/ GRASSES/ TREES/ SHRUBS HAS BEEN PROPOSED.Not Availabl

Not AvailableFIELD EXPERIMENTS WERE CONDUCTED IN ALLUVIAL SANDY LOAM SOILS AT AGRA TO FIND OUT THE EFFECT OF N RATES ( 0,20,40,80 120 AND 160 kg/ha) ON ROOT PROLIFERATION ( RP) , MOISTURE USE EFFICIENCY (MUE) AND UPTAKE OF NUTRIENTS BY MUSTARD UNDER RAINFED (R) AND MINIMAL IRRIGATION (MI) CONDITIONS. APPLICATION OF NITROGEN AT 80 kg N/HA RESULTED IN MAXIMUM TOTAL UPTAKE OF NPK AND ROOT PROLIFERATION WAS ALSO OBSERVED AT 80 kg N/ha RATE. COMPARATIVELY BETTER RESULTS RECORDED UNDER MI CONDITIONS MAY BE ATTRIBUTED TO HIGHER INITIAL SOIL MOISTURE AND AN IRRIGATION OF 30 mm DEPTH BEFORE FLOWERING STAGE.Not Availabl

Not AvailableEFFECT OF N APPLICATION ( 020, 40, 80 ,120 AND 160 kg/ha) ON THE UPTAKE OF PRIMARY NUTRIENTS BY MUSTARD GROWN UNDER RAINFED (R) AND MINIMAL IRRIGATION (MI) CONDICTIONS ON SANDY LOAM SOIL ( RECLAIMED RAVINES) WAS STUDIED. THE N,P AND K CONTENT IN PLANTS , STALK AND GRAIN WERE REDUCED WITH THE APPLICATION OF FIRST INCREMENT OF N ( 20 kg/ha) AND THEREAFTER IT INCREASED WITH THE APPLICATION OF SUCCESSIVE LEVELS OF N. ABSORPTION PATTERN OF NUTRIENTS ( PERIODIC CONTENTS OF N AND P IN PLANTS) INDICATED THAT MAJOR UPTAKE OF N AND P OCCURRED UPTO FLOWERING STAGE ( 60 DAYS) WHILE POTASH CONTENT IN PLANTS PROGRESSED TILL MATURITY . APPLICATION OF NITROGEN AT 80 kg N/HA RESULTED IN MAXIMUM TOTAL UPTAKE OF N ( 48.3 AND 60.6 kg/ha UNDER R AND MI) , P ( 9.38 AND 10.38 kg/ha UNDER R AND MI) AND K ( 63 AND 69.5 kg/ha UNDER R AND MI)Not Availabl

Not AvailableTHE STUDY ATTEMPTS TO ANALYSE 12 SOIL PROFILES AT CHALLESAR (AGRA) REPRESENTING TYPICAL RAVINES USED UNDER AGRICULTURE , HORTICULTURE , GRASSES, MIXED FOREST AND FOREST LANDUSE FOR AVAILABLE NUTRIENTS AND PHYSICO- CHEMICAL CHARACTERISTICS . THE SOILS UNDER DIFFERENT LANDUSES WERE ALKALINE IN REACTION, pH ranged between 7.6 to 9.4, CALCIUM CARBONATE WAS PRESENTED IN ALL THE PROFILES ( 4 TO 19.9%). COMPARATIVELY LOW VALUES OF pH and CaCO3 WERE OBSERVED IN SOILS UNDER PERMANENT COVER OF VEGETATION. THIS WAS MAINLY DUE TO HIGHER CONTENTS OF ORGANIC CARBON (0.45%) OF FOREST SOILS THAN UNDER AGRICULTURE (0.30%) OR HORTICULTURE (0.28%) LANDUSE. AVAILABLE NUTRIENTS ( N, P AND Zn) WERE HIGHER IN SOILS UNDER PERMANENT VEGETATION THAN UNDER AGRICULTURE OR HORTICULTURE LANDUSE AND WERE POSITIVELY AND SIGNIFICANTLY CORRELATED WITH ORGANIC CARBON CONTENTS SOILS ( r= 0.90 -N , 0.82 p AND 0.88 Zn)Not Availabl

Not AvailablePERMISSIBLE EROSION RATES ALSO KNOWN AS SOIL LOSS TOLERANCE ( T VALUE) IS DEFINED AS A MAXIMUM EROSION THAT TAKE PLACE ON A GIVEN SOIL WITHOUT DEGRADING ITS LONG- TERM PRODUCTIVITY . IN INDIA DEFAULT T VALUE OF 11.2 MG HA-1 YR-1 IS USED FOR DEVISING LAND RESTORATION STRATEGIES FOR DIFFERENT TYPES OF SOILS. HOW EVER THE ABILITY OF SOIL TO RESIST DEGRADATION VARIES WITH SOIL TYPE, DEPTH AND PHYSICO - CHEMICAL FEATURES. THEREFORE, THE PRESENT INVESTIGATION WAS UNDERTAKEN TO DETERMINE T VALUE OF DIFFERENT LANDFORMS OF DELHI STATE BY TAKING INTO ACCOUNT SOIL SATURATED HYDRAULIC CONDUCTIVITY (SHC), BULK DENSITY (BD) , ORGANIC CARBON, ERODIBILITY AND SOIL pH . SOIL STATE WAS DEFINED BY A QUANTITATIVE MODEL AND SCALING FUNCTIONS WERE USED TO CONVERT SOIL PARAMETERS TO A 0-1 SCALE. THE NORMALISE VALUES WERE MULTIPLIED BY APPROPRIATE WEIGHING FACTORS BASED ON RELATIVE IMPORTANCE AND SENSITIVITY ANALYSIS OF EACH INDICATOR. CATEGORIAL RANKINGS OF I, II AND III WERE ASSIGNED TO SOIL GROUPS BASED ON OVERALL AGGREGATE SCORE. T VALUE OF DIFFERENT LANDFORMS OF DELHI STATE WAS COMPUTED USING GUIDELINES OF USDA- NATURAL RESOURCE CONSERVATION SERVICES. MAJORITY OF LANDFORMS OF DELHI AND T VALUE RANGED FROM OF 12.5 MG HA-1 YR-1 EXCEPT FOR SOILS OF THE HILL TERRAIN. DISECTED HILLS, PEDIMENT AND PIEDMONT PLAIN, WHERE T VALUE RANGED FROM 5 TO 10 MG HA-1 YR-1 . THESE T VALUE COULD BE USED FOR CONSERVATION PLANNING AND WILL HELP THE PLANNERS IN DEVISING SUITABLE LAND RESTORATION STRATEGIES.Not Availabl
