Two field experiments were conducted in 2003 and 2004 seasons in the
farm of Sers El-Lian Agricultural Research Station. A.RC. Minufiya
Governorate, A.RE. to evaluate three maize varieties under three levels of
nitrogen fertilizer and intcrcropping maize with mungbean at different patterns
and their effect on, yield and its components of the two crops. The results can be
summarized as follows:
- T.W.C. 321 variety gave the highest ear length and ear weight whereas S.C.
10 variety surpassed significantly the other maize varieties in ear diameter,
shelling percentage, 100-grain weight and grain yield/fed.
- Nitrogen application up to 140 kg N/fed caused a significant increase in ear
characters, 100-gnan weight and grain yield/fed. .
- Intercropping pattern 2: 1 significantly surpassed the other patterns in yield
and yield components of maize S.C. 10 maize variety with 140 kg N/feddan
when intercropped with mungbean under 2:3 pattern gave the greatest grain
yield /feddan.
- Mungbean plants when grown with T.W.C. 321 maize variety gave the
highest number of pods and seeds/plant seeds/plant whereas; when
intercropped with S.C. l0variety exceeded seed yield/fed
- Yield and yield components of mungbean were increased by increasing N
level. The increase in N level from 100 to 120 up to 140 kg N/fed increased
seed yield by 14.67 and 26.78%, respectively in the first season and 7.58 and
18.67/., in the second season.
- hitercropping pattern of 2:1 surpassed significantly the other patterns in
number of pods and seeds/pLant and 100-seed weight in the two seasons.
Intcrcropping pattern of 2: 3 gave the maximum seed yieldJfcd The increases
were 34.56 and 15.43% in the first season over those grown in 2: 1 and 2: 2
pattern, respectively and 47.68 and 16.79% in the second season.
- S.C. 10 or T.W.C 321 maize varieties with applied 140 kg N)feddan under
2:3 patterns gave the greatest seed yield of mungbean. :
