Title Growth of Cenchrus pennisetiformis Hochst. & Steud. under amended seawater irrigation in pot culture experiment
Source International Journal of Biology and Biotechnology
Abstract Growth of Cenchrus pennisetiformis Hochst & Sterud was investigated under 10-30% amended seawater (ECiw: 45-14.0 dS.m(-1)) irrigation in pot culture experiment. The data for monthly harvested phytomass around an year indicated extreme reduction of growth during dry and winter months. The salinity and seasonality interacted significantly. The cumulative forage biomass harvested per annum under 30% amended seawater (14.0 dS.m(-1)) irrigation was 281.4 +/- 22.3 g.pot (-1)(FW) as compared to 1025.2 +/- 15.9 g.pot(-1) (FW) in control (1.2 dS.m(-1)). Fifty per cent reduction in total harvested biomass corresponded with irrigation medium of ECiw : 7.04 dS.m(-1) and SAR: 6.29 TL50 values for monthly harvests varied widely with season and were lowest for the month of May (TL50 ECiw : 3.24 dS.m(-1.) TL50 SAR: 3.51). The reduction in total forage production in 10 and 20% seawater was c. 38.5 and c. 63.2% of the control, respectively. The plant showed flowering throughout the year.
