8. Comparative yield and profit of hybrid and composite varieties
From the yields and expenses of trials conducted during kharif 1991, the comparative profits
of cultivating hybrids and composites is shown in Table 15. The hybrid Pacific 11 gave a total
profit of Tk 19,200/ha and Tk 9,911/ha greater than that of Barnali and SUwan 2, respectively.

Thus by spending additional Tk 2,3OO/ha, a profit of Tk 9,911/ha was obtained. The benefit:cost
cost ratio of the hybrid is 2.03 and that for Barnali and SUwan 2 is of 1.04 and 1.67, respectively.
IFDC reported that during kharif 1992, hybrid maize cultivation did not give a financial
benefit significantly greater than that of SUWan 2.
From the yields of Barnali during rabi 1990-91 and 1991-92 (Table 12), it is evident that
the profits from hybrid maize cultivation are negligible. The reason is that the average yields
of all hybrids and composites during rabi were not significantly different (Table 16). However,
P 3252 gave the highest yield of 7.20 t/ha (Table 11), in which case, hybrid maize cultivation
