An experiment was conducted at the Agronomy Field of Sher-e-Bangla Agriculture
University, Dhaka-1207 during the period from August, 2006 to study the responses
of
soybean varieties to different doses of fertilizer. The experiment was carried out
with three soybean varieties viz. Shohagh. Bangladesh soybean-4 and kARl
soybean-5 and four levels of fertilizer viz, no fertilizer, half of the recommended
dose, recommended dose and double
of
the recommended dose. The experiment was
laid out in split plot design with three replications.
The results showed that variety and fertilizer dose signifleantly influenced the
growth,
development. yield characters and yield of the soybean. Among three
varieties, Bangladesh soybcan-4 had maximum plant height, dry matter, number of
branches plani', pod length, number of pod plant" number of seeds pod'. seed
yield, stover yield, biological yield and harvest index. Fertilizer at recommended
dose significantly increased yield with higher values of harvest index as the yield
attributes like pods plant", seed pod" and 1000-seed weight were higher.
In most of the cases Bangladesh soybean-4 coupled with fertilizer at recommended
dose was found to influence yield but double
of
the recommended dose was found to
be associated with better growth. The highest seed yield (2683.0 kg ha") was found
with the interaction of Bangladesh soybean-4 with fertilizer at recommended dose.
This was achieved due to maximum number of pod plant" (41.67), number of seed
pod" (2.04) and greater pod length (3.60). |
