Abstract:
The study investigates the effects of number of irrigation and its intervals in the seed yield and
biomass production of Berseem (Trifolium alexandrinum L.). A Berseem variety "cv. Bardan"
was used in four treatments viz. T1 (with no irrigation), T2 (5 times irrigation in 30 days
intervals), T3 (10 times irrigation in 15 days intervals), T4 (15 times irrigation in 12 days
intervals) and was replicated thrice. The different parameters mainly Berseem seed yield,
biomass production at first cutting, second cutting etc were recorded and statistically analyzed in
completely randomized design (CRD) using MSTAT-C computer software packages.
Significantly higher (P<0.01) average seed yield of Berseem was recorded in the treatments T4
(3.93Q/ha) with 15 times irrigation in 12 days intervals which is followed by T3 (3.6Q/ha), T2
(2.6Q/ha) and lowest in treatments T1 with 2.0Q/ha. Similarly, the effect of number of irrigation
and its intervals on average biomass production of Berseem at first and second cuttings has the
similar results in all the treatments. Significantly higher (P<0.01) total biomass production of
Berseem is recorded in T4 (98.83 ton/ha) by three cutting in one month interval followed by T3
(89.03 ton/ha), T2 (81.06 ton/ha) and T1 (64.00 ton/ha). These results clearly reveal the
importance of combination in the number of irrigation and its intervals. Fifteen times of
irrigation in 12 days intervals is required for better seed yield and biomass production for the
entire crop duration of Berseem. Irrigation sequence has great impact in the production system
and the productivity of Berseem seed yield and total biomass. |
