EFFECT OF IRRIGATION INTERVALS AND DISTRIBUTION OF MAIZE ON YIELD AND COMPONENTS OF RICE/MAIZE INTERCROPPING.
Two field experiments were conducted during 2011 and 2012 summer seasons at Gemmeza Research Station,El Gharbia Governorate,Egypt,to study the influence of irrigation intervals and distribution of maize plants on yield and its components of imaize and rice intercropped.The experiments were coducted in strip splot design,with three replicates,where irrigation intervals were every 6 days (I1),every 10 days(I2) and every 14 days(I3) occupied the vertical plots (strip) and distribution of maize plants (one plant with 20cm between hils,two plants in hill with40cm between hills and three plants in hill with 60cm between hill) were assigned to the horizontal plots. Results were summarized as follows;
1- All the traits of rice were significantly affected by irrigation intervals in both seasons,except, unfilled grains % in the second seasons.I1 followed by I2 treatments gave the highest values between all the characters of rice in both seasons,however, I3 treatment recorded the lowest values ,except, unfilled grains%.
2-All characters of maize were significantly affected by irrigation intervals in both seasons,except, ear height,stem diameter, number of leaves/plant and ear leaf erea in the two seasons and weight of grains/ear in the first seasons.However,all characters for maize had insignificant by distribution of plant of maize in both seasons,except,100-grain weight and grain yield/fed in the second season and plant height, ear length and weight of grains/ear in the two seasons.
3- The interaction between irrigation and distribution of maize plant had insignificant effect on all the traits of rice and maize ,except, weight of grains/ear and 100-grain weight for maize in the first seasons.
4-The highest values of Land equivalent ratio(LER)were 1.298 and1.293 in the two seasons,respectively,with irrigation intervals I1 and I2,respectively.
5-Relative crowding coefficient (RCC)was 4.21 and4.75 in the two seasons were recorded with irrigation intervals I1 and I2 ,respectively.
6-Aggressivity(Ag) indicated that rice was the dominat crop ,whereas, maize was the dominated in both seasons.
7-The highest gross return was obtained with( I1 )
Generally , it could be concluded that irrigation every 6 days and planting maize with three plants/hill with distance 60 cm between the hills could be used to obtained high grain yield for rice and irrigation every 14 days and3 plant /hill of maize at distance 60 cm for maize.
