CONSERVATION AGRONOMY TECHNOLOGY FOR BELLARY SEMI- ARID BLACK SOIL REGION

Abstract

STUDIES CONDUCTED IN BLACK SOILS OF BELLARY REGION HAVE INDICATED THAT BLADE HARROWING ( SHALLOW) AFTER EACH SOAKING RAIN AND DEEP PLOUGHING AT 2-3 YEARS INTERVAL WAS FOUND GOOD. SORGHUM, SAFFLOWER , DOLICHOS , REDGRAM , LIMEBEAN , CASTOR AND CORIANDER ARE EFFICIENT AND REMUNERATIVE CROPS IN THE REGION. SORGHUM VARIETIES , SPV- 511, 570 AND 504 WERE PROMISING . IT SHOULD BE SOWN IN SPETEMBER WITH THE ONSET OF RAINS WITH 45-90 cm ROW SPACING. DOLICHOS AND CLUSTERBEANS ARE IDENTIFIED WITH HIGH YIELD POTENTIAL AND MAXIMUM DROUGHT TOLERANCE , RESPECTIVELY. REDGRAM, SAFFLOWER AND CORIANDER WITH DROUGHT TOLERANCE AND SUITABILITY FOR LATE SOWING ARE AN IMPORTANT CONSTITUENT OF CROPPING PATTERN . INCLUSION OF DOLICHOS IN CROPPING SEQUENCE , BENEFITS THE CEREALS AND IMPROVES SOIL CONDITION. INTERCROPPING OF DOLICHOS IN SORGHUM IN 3:1 RATIO WAS PROMISING
