Grain yield, in tons per ha:
See
Table 3
Statistical
results show that the highest grain yield of 5.89 toms
per ha. obtained from plants treated with CB-RSG alone
(T7) was comparable with those treated with M-99 alone
(T2) and those applied in combination the 1/3 (T4), ½
(T6) or full M-99 (T8). The significant increased yields
in T3 vs. T4 (1.65 tons per ha) and T5 vs T6 (1.58 tons
per ha.) were attributed to CB-RSG. Additional
application of CB-RSG to M-99 did not significantly
increase grain yields than the untreated plants. It is
worthwhile mentioning at this point that while CB-RSG
seemed to effect the relatively low straw weight of rice,
it appeared to have somewhat boosted its grain
development.
