A study was conducted covering a total of one hundred chicken farmers in tribal dominated Boko Block of Kamrup district in Assam to assess different productive and reproductive traits of Desi, Vanaraja and Srinidhi birds under field condition. Information was obtained on mean body weight at various ages, age at first egg, annual egg production, fertility and hatchability and mortality rate. Body weight, egg production and egg weight were significantly(P<0.05) higher in Vanaraja and Srinidhi birds compared to Desi chicken. The age at first egg was significantly (P<0.05) higher in Desi chicken while compared with Vanaraja and Srinidhi under traditional system of management. However no significant (P<0.05) difference was found between Vanaraja and Srinidhi in their body weight and egg production at various ages. Higher mortality percent in Vanaraja (12.23'1.62) and Srinidhi (11.34'1.23) were recorded during 0 to 5 week. No significant (P<0.05) differences were found among all three groups of birds in fertility and hatchability. [ABSTRACT FROM AUTHOR]

A rapid reconnaissance soil survey of Markapur mandal of Prakasam district, Andhra Pradesh was carried out in 2009-10 using geo-referred false colour composite image (IRS-P6, LISS-III) and Survey of India (SOI) topo-maps (1:50,000 scale) set. The soils of hill side slope and undulating pediments developed over quartzite, sandstone and shale complex was shallow to moderately deep, brown (7.5 YR 4/4) to dark brown (7.5 YR 3/4) in colour, well drained with poor fertility. These soils are under forest, open scrub and rainfed farming in patches. The soils of pediplains and stream bank from shale was yellowish red (5 YR 4/6) to dark reddish brown (5 YR 3/3), deep to very deep low fertility and cultivated (rainfed) in pediplains but waste land in stream bank. The soils of undulating pediments and hill side slope were grouped under land capability class IV and VII whereas soils of pediplains and stream bank were placed under land capability class II and III respectively.
