Abstract
Manure
and nitrogen are important nutrient source for crops. These materials
are directly related to crop growth and quality production. Present
study revealed the effects of manure and split application of
nitrogen on nutrient contents in maize. The study was performed at
the experimental field of the Department of Agronomy, Sher-e-Bangla
Agricultural University, Dhaka-1207 in Bangladesh during the period
from March 2006 to June 2006 comprising two split applications of
nitrogen (SP1= 25 and 45 days after sowing and SP2=25, 45 and 65 days
after sowing) and four manure (M) application doses (M1=0, M2=5,
M3=10 and M4=15 t ha-1). The treatments were arranged in split plot
design with three replications. N, P and K contents both in the grain
and stalk tissue increased significantly with the increase in both
the split number and manure dose. N, P and K contents in grain and
stalk tissues were analyzed. The highest N contents in grain and
stalk tissue were obtained with SP2, M4 and SP2M4 (2.06 & 0.92,
2.25 & 0.91 and 2.40 & 0.94% respectively). These treatments
also had the highest P contents in grain and stalk tissue (0.14
&0.14, 0.18 & 0.18 and 0.15 & 0.15% respectively). Like
wise these treatments had the highest K contents in grain and stalk
tissues (2.06 & 0.92, 2.25 & 0.91 and 2.40 & 0.94%
respectively).
