Abstract
Dichanthium annulatum (Forak) Stapf, is indegenous to Indian sub-continent. It is considered to be one of the best known pasture grass of India. The present investigation was undertaken with a view to determine the effect of different levels of irrigation and fertilizer on seed production of two varieties of D. annulatum viz. Local and S-32. A field experiment was conducted at Gujarat Agricultural University, Anand Campus, Anand during Kharif season of the year 1979-80. Eighteen treatments involving combinations of three irrigation levels, viz. No irrigation (I0), irrigation at 100 per cent flowering (I1) and irrigation at 100 per cent flowering + 20 days (I2) in main plots and two varieties (Local (V1) and S-32 (V2) and three fertilizer levels (No fertilizer (F0), 30 kg N+ 15 kg P2O5 + 15K2O/ha (F1) and 90 kg N + 45 kg P2O5 + 45 kg K2O/ha (F2)) in sub-plots were laid out in a split-plot design with four replications. The root slips of local and S-32 varieties were planted in the first week of July.
