The present invitation entitled “ Effect of changing rainfall situation on yield of pearl millet in medium deep soil of scarcity zone of Maharashtra.” was carried out during 2016-20 at Zonal Agricultural Research Station, Solapur, Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra (India). The experiment was conducted in split plot design with three replications. Nine treatment combinations were formed considering different cultivars viz., V1(ICTP-8203), V2 Mahyco Hybrid and V3 Dhanashakti and sowing windows viz., (S1) 2nd fortnight of June (25th June), (S2) - 2nd fortnight of July (27th-July) S3 - 2nd fortnight of August (24th - August). Among the three pearl millet sowing window crop sown in second fortnight of July (S2) produced significantly higher grain yield (1518.9 kg ha-1), biomass yield (2658.1 kg ha-1), total monetary returns (Rs. 33090 ha-1),CUM(383.7 mm), (MUE) (3.95 Kg ha-1 mm), GDD (1941-20610 days) and RUE (1.19g MJ-1) than other sowing dates. Among the genotypes Dhanashakti produced significantly higher grain yield (1369.9 kg ha-1), biomass yield (2525.5 kg ha-1) and total monetary returns (Rs. 29994 ha-1) than other cultivars. Under changing rainfall situation sowing of Kharif pearl millet contingent crop variety Dhanashakti upto 02nd September (Meteorological week no. 34-35) in medium deep soil of scarcity zone of Maharashtra is recommended for more sustainability in production. Following regression equation based on weather parameters for predicting the yield (prior to 2 weeks) is recommended. ÖYield= -101.38 + (-0.21 x Tmin) + (2.49 x RH-1) + (-1.34 x RH-2) + (0.08 x RF).
The field experiment was conducted at research farm, Zonal Agriculture Research Station, Solapur Mahatma Phule Krishi Vidyapeeth,Rahuri for five years (2016-17 to 2020-21) in rabi on sorghum entitled as “Studies on Sowing windows for Sustainable Production of Rabi Sorghum (Sorghum bicolour L.) Under Changing Climatic Condition in Scarcity Zone of Maharashtra.” to find out most optimum meteorological week for sowing sorghum in rabi season, to study the relationship between meteorological parameters and yield by using four different sowing windows. The results were obtained from the experiment; it was found that rabi sorghum sown at MW 40 (01-07 Oct) produced maximum pooled grain yield (808.28 kg ha-1), fodder (1494.11 kg ha-1) and total monetary returns (Rs. 26633 ha-1). Among the varieties, M-35-1 was produced significantly higher grain yield (717.94 kg ha-1), fodder yield (1559.03 kg ha-1) and total monetary returns (Rs. 24968 ha-1) over the other variety. The meteorological studies showed that the mean CUM and MUE recorded by sorghum crop was 240 mm and 2.7 kg ha-1 mm. The highest CUM was recorded by S1 sown crop (282 mm) however the MUE was recorded by S3 sown crop (3.5 kg ha-1 mm). This indicated that S3 sown crop (Chitra Nakshtras) utilized moisture more efficiently than other dates of sowing. Among the variety M-35-1 recorded maximum mean CUM (266 mm) and MUE (3.1 kg ha-1 mm) than other varieties. The number of days required to attain physiological maturity and growing degree days were higher in S3 sown crop. Among the varieties it is higher in M 35-1 than Mauli and Yashoda. In case of RUE initially values were low, it increases up to 70 DAS (i.e. up to 50 percent flowering to soft dough stage) further it decreases in all most all the sowing dates.
