Abstract:

An experiment entitled “Effect of weather parameters on crop growth, development and yield of Kharif Cotton varieties under extended sowing times” was conducted during 2016-17 at Research farm AICRP, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Kharif season. The field experiment was lay out in a split plot design with three replications. There were thirty six treatment combinations comprising of four sowing times viz., 24th, 25th, 26th and 27th MW as main plot treatments and three varieties viz. Ajit-155, Mallika and Rashi-2 (779) as sub plot treatments. Among the three different varieties of cotton, Ajit-155 and Sowing of cotton during 25th MW recorded significantly higher growth parameters viz., plant height, number of branches per plant with yield attributing characters viz., number of boll per plant, grain yield, straw and biological yield. The variety Ajit-155 and sowing time 25th MW was significantly superior over other varieties and sowing times. The highest grain, straw yields and biological yield were recorded with the variety Ajit-155 sown for 25th MW due to increased seed yield (kg ha-1) than other varieties. The result of the study indicated that thermal indices influence at 25th MW to favorably improved growth and attributes and yield of cotton variety Ajit-155. The rainfall, minimum temperature, RH-I and RH-II has been positively correlated with seed, straw and biological cotton yield of Ajit-155, Mallik and Rashi-2 (779) varieties, while maximum temperature and BSS has negatively correlated of Ajit-155, Mallik and Rashi-2 (779) varieties respectively. A research work on correlation studies between weather parameters and plant characters of cotton crop varieties under extended sowing times is very meager, hence efforts are made to focus light on it.
