ABSTRACT
The addition of organic matter improves yield, fiber quality and seed germination of cotton. The present studies were conducted at Cotton Research Station Vehari, Punjab, Pakistan during 2016 to find out the impact of organic matter on growth and yield of cotton. Farm yard manure and green manuring of berseem was done for consecutive four years to improve soil organic matter from initial organic matter of 0.7% and improved to 1.0 % after two years and after repeated use, it improved to 1.5 % during fourth year. Three levels of organic matter i.e., <0.5%, 1% and 1.5% were studied. It was found that by increasing organic matter significant increase was observed in all studied traits (Number of bolls per plant, boll weight, boll retention %, seed germination %, seed index and fiber characteristics). However, T3 (organic matter (1.5%) showed maximum increase in all characteristics. In T2 (organic matter 1%) varieties showed 15.8 to 19% increase in bolls per plant and 33.3 to 36.8% in T3. In treatment with organic matter (0.5%) the boll weight was (2.46gm), number of bolls (19.0), boll retention (38.0%), Ginning Out Turn (GOT) (37.7%), fiber strength (30.7), staple length (28.0mm), fiber fineness (4.3), seed germination (64.7%) and seed index (6.67%) respectively. In treatment with organic matter (1.5%) boll weight was (5.3gm), number of bolls (28.3), boll retention (66.3%), GOT (40.3%), fiber strength (35.4), staple length (29.4mm), fiber fineness (4.6), seed germination (88.7%) and seed index (9.7%) respectively. FH-Lalazar responded better to organic matter and its yield was more as compared with MNH-886 and VH-311. It is suggested that farming community should focus on enhancement of organic matter and varieties highly responsive to it for better productivity in future.
