Enhancing Seed Productivity of Male Parent of Dch-32 Cotton Hybrid : Studies on Enhancing Seed Productivity of Male Parent SB(YF) 425 of DCH-32 Cotton Hybrid

STUDIES ON ENHANCING SEED PRODUCTIVITY OF MALE PARENT SB(YF) 425 OF DCH-32 COTTON HYBRID.The major factors attributed for the difference in the yield of seed cotton are the yield attributes viz., number of flowers produced per plant, number of bolls per plant, boll setting percentage and boll weight. It is well known that adverse climatic conditions bring on imbalance in the growth and development of plant leading to the shedding of reproductive parts, there by reducing the yield considerably in cotton. The micro nutrients are capable of redistributing dry matter in the plant thereby bringing about an improvement in the yield. In cotton, the seed cotton yield depends on the accumulation of photo assimilates and partitioning in different parts of the plant. The yield is strongly influenced by the application of micro nutrients indicating the role of these micro nutrients in increasing the yield through their effect on various morpho-physioligical traits. Foliar application of micro nutrients is known to increase the yield of cotton crop.
