Estimation of Root and Shoot Biomass of Cenchrus ciliaris (Dhaman) Under Barani Conditions

M. Umar Farooq, Rashid Saleem and Abdul Razzaq    

Abstract: Cenchrus ciliaris a palatable and nutritious grass is a warm season grass. Arid and semi-arid rangeland are reseeded with Cenchrus ciliaris to enhance productivity, prolong grazing season and increase carrying capacity. A two ha land area was reseeded with Cenchrus ciliarisat target area Jamrud in June 1980, under barani conditions. Generally shoot biomass is determined at the end of growing season after seed maturity stage. Root shoot and root biomass of Cenchrus ciliarishas not estimated/determined at the end of spring season. The different growing season (spring summer) is lacking. Estimation of shoot and root biomass of Cenchrus ciliaris plant in two growing different seasons is essential in grazing management studies. At the beginnings of spring season reserve carbohydrates are used for the production of new shoots. The shoot biomass at the end of spring season is generally less compared to the end of summer season. The shoot and root biomass estimating of Cenchrus ciliaris plant at the end of two different growing season is required to devise the grazing management programme. This study is proposed to quantify the shoot and root biomass of Cenchrus ciliaris plant at the end of spring and summer growing seasons.
