Split-split arrangement according to randomized complete block design (RCBD) with three replications was used. The data were analyzed and the averages were tested according to the least significant difference at 0.05 probability level. The most important results obtained that, seeding dates affected most of the outcome indicators , and 15 August achieved the highest number of rows (18.52) per year, grains per row (316.3 grains), weight of 100 grains (32.52 g), plant grain yield (130.2 g) and total grain yield (8.011 t ha-1). The plant density caused significant effect , and the low density achieved the highest ear rows number (15.42) and plant grain yield, while high density achieved the highest total grain yield (7.102 t ha-1). Silicon spraying caused significant effect and the concentration of 4.5 ml/L-1 gave high plant grain yield (94.4 g). The interactions had a significant effect on most of the studied traits.

A third factorial experiment under randomized complete block design (RCBD) with three replications was used. Local variety seeds were cultivated on 15/8/2018 in ridges 80 cm (planted on both sides) at 15 cm between hills. The results showed that adding urea gave high plant pods number, pod seeds number, and seeds yield (27.5, 7.2 and 1395 kg. ha-1) significantly compared to control. Spraying foliar fertilizer number gave high plant pods number, pod seeds number and seeds yield compared to control and spraying three times was superior by giving (28.6, 7.2 and 1454 kg ha-1). Spraying seaweed extract caused significant increases in plant pods number, pod seeds number and total seed yield compared to control without differences between the level of 1000 and 2000 mg L-1. The combination of adding urea and foliar fertilizer 2 or 3 times was superior in total seed yield (1503 and 1513.8 kg ha-1). The combination of three times foliar fertilizer and spraying seaweed extract at 1000 or 2000 mg L-1 gave the highest total seed yield (1529 and 1546.5 kg ha-1). The combination of adding urea and spraying seaweed extract at 2000 mg L-1 gave the highest total seed yield (1464 kg ha-1).

The application of soil fertilizers caused a significant increase in the activity of CAT, APX, GSH, but it had no significant effect on SOD activity. While it caused a significant decrease in proline and a changeable effect on ascorbic acid content whereas compound fertilizer caused a significant reduction in ascorbic acid compared to control. The organic fertilizer caused a significant increase in ascorbic acid compared to control. Foliar fertilizers resulted in significant increase in the activity of CAT, SOD, GSH and proline, but it had no significant effect on APX and ascorbic acid compared to control. The interactions between the factors caused significant effects on all parameters.

The results showed that using mulch, fertilizer treatment and the interaction between mulch and fertilizer treatment led to a significant increase in leaf area and chlorophyll content. In general, using mulch+ fertilizers, which caused increases in free and bound hormones (IAA, GA3 and Zeatine) and decrease in ABA and to less extend by using mulch without fertilizer.

Split – split blot design in randomized complete blocks design (RCBD) in three replications was used. The factors were: soil fertilizer with urea (0, 100 and 200 kg ha-1) which were given symbols (U0, U100 and U200) respectively, and three agricultural sulfur levels (0, 10 and 20 kg ha-1) which were given symbols (S0, S10, S20) respectively, and two levels of spraying urea (spraying and control). The spraying was done twice (at 12 leaves stage and silk appearance stage at concentration of %0.05 even full wet) which were given symbols (A0, A1) respectively. The results showed that 200 kg ha-1 (U200) was superior significantly in ear rows number, grain number per row, the weight of 300 grain (19.42 , 45.5 , 45,2 g) . ...

Split-split plot arrangement in randomized complete block design with three replications were used. The irrigation treatments (A0, full irrigation and A1, deficit irrigation), were operated at main plot , while sub plot operated phosphorus concentrations B0, B1, B2 (without spray, spray phosphorus concentration of 1000 and 2000 mg P.l-1), and salicylic acid concentrations C0, C1, C2 (without spray, 0.5 and 1.0 mM, respectively) in sub-sub plots. Maize seed (cv. Buhooth 106) were seeded in 20/7/2013 on ridges(70 cm) , and the data on vegetative growth were calculated and analyzed and the average were tested according to least significant difference. The most important results were summarized as follow: Deficit irrigation led to a signific...
