Abstract

The Operational Research project is functioning at Zonal Agricultural Resarch Station, Solapur with one of the objective to demonstrate the impact of in situ moisture conservation techniques viz., ridges and furrow and compartmental bunds under farmers management condition and secondly to popularize the productive technology amongst farmers in the Sarole watershed, Tal. Mohol, Dist. Solapur during the period 2002-03 to 2005-2006. The in situ moisture conservation techniques were adopted on 15 farmers field having plot size 0.20 ha. each treatments during Kharif and Rabi sorghum (M-35-1) was grown as test crop following all recommended practices. The results revealed that, the average grain yield of sorghum was highest in ridges and furrow (9.64 q ha^-1), compartmental bunding (8.24 q ha^-1)as compared to farmers practice i.e., two harrowing. The per cent increase in grain yield was 17 per cent in ridges and furrow over compartmental bunding and 54 per cent over farmers practice. Similar trend was also noticed in case of fodder yield of Rabi sorghum.

Abstract

The experiment was laid out in Factorial Randomized Block Design with twelve treatment combinations, formed due to three varieties (Tapi (JLT-7), Phule Til-1and Hawari) and four levels of fertilizer (0, 12.5 + 6, 25+12.5 and 37.5 + 18.5 N + P₂O₅ kg/ha) replicated three times. Amongst the three varieties studied, the mean values for height, spread of plant, number of functional leaves were more in the variety Phule Til-1 at 60 days. The total dry matter accumulation per plant, straw yield, straw to grain ratio were also more in Phule Til-1. the number of capsules and branches per plant, number of seeds per capsule, thousand grain weight, grain to empty capsule ratio and harvest index were significantly more in variety Tapi (JLT-7). Due to expressions of higher order for yield contributing characters, the variety Tapi (JLT-7) produced significantly more grain yield and oil yield. The protein content in the varieties was found to be non-significant. The variety Hawari is early type and required less days for maturity as compared to the rest of the varieties. The growth attributes viz., plant height, spread number of functional leaves and dry matter accumulation per plant were influenced by different fertilizer levels. The values of the yield attributes viz., number of capsules, grain weight per plant and thousand grain weight were increased with every successive increased level of fertilizer and was maximum with 37.5 kg N+18.5 kg P₂O₅ ha. The grain (9.93q/ha), straw (20.97 q/ha) and oil (4.68 q/ha) yields obtained due to the application of 37.5 kg N+18.5kg P₂O₅/ha were the highest and significantly more than the rest of the lower levels.

Abstract

Factorial randomized black design was laid out with twelve treatment combinations, formed due to four levels of fertilizer (0,12.5+6,25+12.5 and 37.5+18.5 N+p₂0₅ kg/ha), three varieties (Tapi (JLT-7), Phule Til-1and Hawari) and replicated three times. Amongst the three varieties studied, the mean values for height, spread of plant, number of functional leaves were more in the variety Phule Til-1 at 60 days. The total dry matter accumulation per plant, straw yield, straw to grain ratio were also more in Phule Til-1. The number of capsules, branches per plant, number of seeds per capsule, thousand grain weight, grain to empty capsule ratio and harvest index were significantly more in variety Tapi (JLT-7). Due to expressions of higher order for yield contributing characters, the variety Tapi (JLT-7) produced significantly more grain yield and oil yield. The protein content in the varieties was found to be non-significant. The variety Hawari is early type and required less days for maturity as compared to the rest of the varieties. The growth attributes viz., plant height, spread number of functional leaves and dry matter accumulation per plant were influenced by different fertilizer levels.
