Abstract

This study was conducted at Biochemistry Section, Post Harvest Research Centre, Ayub Agricultural Research Institute, Faisalabad, Pakistan during the years 2006, 2007 and 2008 to evaluate different varieties/lines of sorghum fodder for hydrocyanic acid and crude protein contents. Ten varieties i.e. JS- 2001, JS-263, Hegari, F-9601, F-9603, F-9706, BS-1, SS-1, SS-2 and Jowar-86 were sown in randomized complete block design with three replications. Recommended dose of NP fertilizers was applied to the crop each year. Crop was harvested at maturity, green fodder yield was recorded and samples were analyzed for HCN and crude protein contents. On mean basis the results revealed significant differences among varieties for better yield, HCN and crude protein contents. Variety JS-2001 produced the highest green fodder (70.9 t/ha) while variety SS-2 gave the lowest (51.1 t/ha). Hydrocyanic acid contents ranged from 255.4 ppm (F-9601) to 346.6 ppm (Hegari). However, these values were within safe limit of 500 ppm. Crude protein contents ranged from 4.4 to 5.1 percent. Variety JS-263, Hegari and F-9603 showed the highest value (5.1 %) against the lowest by F-9706 and JS-2001 (4.4 %). On overall basis varieties JS- 2001 due to higher green fodder yield and low HCN contents and JS-263 with higher crude protein contents and higher fodder yield were found comparatively better than all other varieties / lines.
