SUMMARY

Cluster bean (Cyamopsis tetragonoloba) is a legume crop grown in kharif season. However, the average productivity of guar in the district (751 kg/ha) is very low as compared to potential yield of new varieties (20 q/ha). The productivity of this crop is low in the district due to poor adoption of improved technologies of guar by the farmers. The KVK, Fatehpur has carried out 140 FLDs on guar (RGC-1066) in 24 selected operational villages covering an area of 58 ha during 2013 to 2018 to exhibit latest proven technologies & to know the productivity & economics of demonstrations compared with farmer’s practices. The average yield of six years data was recorded 14.40 q/ha in FLDs and 12.00
q/ha in farmers practice with an additional yield of 2.40 q/ha and productivity increased by 20.19 per cent. The average technology gap and extension gap were found 5.59 and 2.40 q/ha respectively. The result shows positive effect of FLDs of improved variety (RGC-1066) & new proven technologies of guar over the existing practices towards enhancing the productivity of guar in the district. The improved variety RGC-1066 gave higher six years average gross return (Rs 64387/ha), net return (Rs. 41103/ha) with higher cost benefit ratio of 2.79 as compare to farmer’s practice average gross return (Rs. 54050/ha), net return (Rs. 33067/ha) with cost benefit ratio of 2.56 in the six years from 2013 to 2018. The horizontal spread of improved new variety RGC-1066 among 350 farmers of nearby 30 villages over more than 450 hectare area show positive impact of FLDs.

SUMMARY

The fodder Oat variety “Central Fodder Oat OS 424” is suitable for timely sown, normal fertility and irrigated conditions for Hill Zone of India Himachal Pradesh (J & K and Uttrakhand) conditions of India. Central Fodder Oat OS 424 gave 296.5 q/ha green fodder yield which is 15.8% and 15.6% more than the national checks Kent (256.0 q/ha) and OS 6 (256.4 q/ha), respectively. It showed superiority of 12.5% green fodder yield than the zonal check SKO 90 (263.6 q/ha). Variety Central Fodder Oat OS 424 gave 65.1 q/ha dry matter yield and it out yielded the best national checks Kent (55.3q/ha) by 17.6% and OS 6 (55.9 q/ha) by 16.4%. This variety out yielded the zonal check SKO 90 (58.3 q/ha) by 11.7%. Variety Central Fodder Oat OS 424 also gave 23.3% higher per day productivity of GFY over best national check Kent while it gave 11.2% higher GFY per day productivity over the best qualifying variety SKO 225. The variety Central Fodder Oat OS 424 gave a seed yield of 13.5 q/ha. The variety Central Fodder Oat OS 424 is at par with checks and other entries for Powdery Mildew. The variety responded significantly up to 120 kg N/ha for GFY and DMY both. The variety Central Fodder Oat OS 424 is good in nutritional quality as well by showing 8.9% crude protein which is at a par with the national checks Kent (9.0%) and OS 6 and zonal check SKO 90 (8.7%). It was almost at par with the checks and qualifying varieties for NDF and ADF %.

Key words: Fodder Oat, Timely sown, Normal fertility, irrigated conditions

SUMMARY

The new single-cut oat variety, HFO 607, was developed by Forage Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar. It was released and notified for cultivation under timely sown, normal fertility and irrigated conditions in North West Zone of India (Rajasthan, Punjab, Haryana, Terai region of Uttarakhand and Western Uttar Pradesh). It was developed through pedigree method of breeding. This variety gave 615.7 q/ha green fodder yield in North West Zone which was 11.9% and 17.4 % higher than the national checks Kent and OS 6, respectively. It also showed superiority of 8.8% for green fodder yield than the zonal check OL 125 (NWZ) (average of three years over different locations) in North West Zone of the country.
