YIELD AND CORRELATION STUDIES IN DIRECT SEEDED RICE AS INFLUENCED BY IRRIGATION LEVELS

R. Balasubramanian, J. Krishnarajan

Open publisher page 5 citations

Abstract

Field experiments were conclucted during kharif and rabi seasons (1997–98) to study the effect of different water management practices on yield, water use and water use efficiency of direct seeded rice. The results revealed that the yield and water use efficiency were better with continuous submergence of 2.5 cm depth throughout the crop period as the irrigation regime was not significantly different from higher water regimes. Simultaneously, the correlation was worked out between yield and other components.
