Phenology of development, productivity of green mass, grain and crude protein of chickpeas (Cicer arietinum L.) under the conditions of Central Northern Bulgaria

Abstract

The field experiment was held the period 2010 – 2012 in Institute of Forage Crops, Pleven. The objective is to study the phenological development, productivity of green mass, of grain the crude protein of Chickpeas (Cicer arietinum L.) under the conditions of Central Northern Bulgaria. The results showed that vegetation period under the conditions of the experiment are on average 110 days. With largest share in the green mass of the chickpeas are the leaves (50.7%), follows that of the stems (40.8%) and the lowest proportion of inflorescences (6.7%). To research period the yield the fresh mass it is 2100,4 kg/da, the dry mass is 458.12 kg/da, and crude protein the feed – 77.4 kg/da. Grain production is equal to 159.0 kg/da and crude protein derived from grain respectively 35.1 kg/da.
