Abstract
Two field experiments were carried out in Wady-El Areish North Sinai Governorate during the two growing seasons of 1998 and 1999. Soil texture was sandy, moderate in salinity and poor in organic matter and nutrition of elements. This work aimed to study response of maize S.C 10 to two planting methods; ridges and rows and 7 times of foliar application with micro- and macro-elements. Strip design in split plot with 4 replicates was used in this investigation, main plots (horizontal) were devoted to planting methods and sub-plots (vertical) were occupied by foliar application times. The main results obtained from this study could be summarized as follows:
- Ridges method surpassed rows method, stimulate the vegetative growth and most of traits under study and increased grain yield with average 21.62 % than rows method.
- Spraying time at 30, 45 and 60 days from planting with foliar application (Nervatin-Vit) formula (10% N, 8% P2O5, 7% K2O, 0.6 % Mg, 1.1% Fe, 0.5% Mn, 0.5 % Zn, 0.05% B, 0.02% Mo, 0.02 %Cu) with rate of 1.8 liter /fed was significantly increased no. of days to 50% tesseling, no. of days to 50% silking, plant height, stem diameter, leaf area/plant, ear position, ear length and diameter, no. of kernels, kernels weight /ear, shilling percentage, 100-kernel weight and grain yield ardab /fed than the others application times (control, spraying at 30, 45, 60, (30, 45) and (45, 60) days from planting with dose of 0.0, 0.6, 0.6, 0.6, 1.2 and 1.2 L /fed, respectively from mentioned formula.
- The contents of N, P and K (4.2, 0.5, 3.0 % dry weight, respectively in ear leaf at one week after silking) and Fe, Mn, Zn and B (220, 110, 75 and 15 mg/kg dry weight of ear leaf at one week after silking, respectively) gave the maximum grain yield of maize which resulted from spraying at 30, 45 and 60 days from planting.
In general, the results of this study recommended that planting maize S.C 10 with ridge methods and foliar application with rate of 1.8 L/fed / season from this foliar nutrient divided on 3 intervals times at 30, 45 and 60 days from planting gave the higher grain yield under the condition of this experiment.
