Green gram (Vigna radiata L. Wilczek) is one of the most important pulse crops of global economic importance. It is locally called as moong or mug and belongs to the family Leguminoceae, it fixes atmospheric nitrogen and improves soil fertility by adding 20-25 kg N ha -1 (Md Tariqul Islam, 2015). Mung bean has originated in India and is a native of India and central Asia. It is grown in these areas since prehistoric period. Mung bean is grown
The weekly rainfall data for 36 years (1981-2016) recorded at Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani were analyzed for mean seasonal, weekly rainfall and also weekly rainfall probabilities. The mean seasonal rainfall was 796 mm, received in 38 rainy days. The seasonal rainfall indicated that there is 53% chance of receiving less than 700 mm with variable intensities and 36% chance of getting more than normal rainfall and 11% chance of seasonal rainfall, in between 700 mm to 800 mm. The mean weekly rainfall during crop season was 45.8 mm with a CV of 116%. Highest mean weekly rainfall was recorded 71.8 mm with SD (95.3) and CV (132.7%) in 30th MW. Sowing of Kharif crops should be undertaken during 24th MW to 27th MW. Significant and positive correlation between yield and rainfall was observed for Soybean, Pigeonpea, Black gram, Green gram and rice. The predictability of productivity of crops using seasonal rainfall is 10-20% variation in productivity for all the crops at the Centre. The El Nino episode was negatively influencing Southwest monsoon and annual rainfall as well as rainfall during the months of July and September. El Nino episodes exhibit more negative influence on productivity of all the crops except rice crop. Among the different categories of El Nino, weak events exerted more negative impact on productivity of short duration crops (i.e., sorghum, soybean and Black gram) as compared to moderate and strong El Nino events.
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., 24 th , 25 th , 26 th and 27 th 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 25 th 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 25 th 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 25 th MW due to increased seed yield (kg ha-1) than other varieties. The result of the study indicated that thermal indices influence at 25 th 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.
