A field experiment was conducted in Sowairah Research Station-General commission for Agriculture Researches during the winter season of 2012-2013, in order to study the effect of four seeding rates 100, 120, 140 and 160 kg.ha-1, on grain yield and its quality for four cultivars of barely (shua'a, Amal, Sameer and Al-khair), using a split-plot arrangement in Randomized Complete Block Design (RCBD) in three replicates.
The results showed the following:
The seeding rate 160 kg.ha-1 was significantly superior in plant height 99.06 cm, number of spikes.m-2 270.20 spike grain yield 3.67 ton.ha-1, protein concentration in grain 8.82% and protein yield 322.72 kg.ha-1, while there was no significant effect of seeding rate on number of grain per spike.
Significant differences were found between all cultivars in all characters, Sameer cultivar was superior in plant height and protein concentration in grain (9.39%), Shua'a cultivar was superior in number of spikes.m-2 260.5 spike, and Al-Khair cultivar was superior in number of grain per spike 50.74 grain, grain yield 4.10 tonne.ha-1 protein yield 380.36 kg.ha-1. The interaction between seeding rate and cultivars effect in number of spikes. m-2, protein concentration in grain and protein yield. The combinations between Al-Khair cultivar and seeding rate of 140 and 160 kg.ha-1 gave highest average of protein yield of 416.11 and 417.31 kg.ha-1 respectively.

Eight inbred line of maize were crossed in a half-diallel mating system . The seeds of parents and F1 crosses were sown in fall and spring season using a randomized complete block design ( R.C.B.D) with four replications . The characters studied were : leaf area / cm2,number of ear/plant ,ear length, number of rows/ear ,number of grain /ear ,300 seed weight and yield of single plant .The parents( H5,R153,ZP607,W13R, JEEZA 5 ,JEEZA 275, SP18 , SP19 ) and these crosses showed a significantly for all characters except number of ear/plant , The parents were generally combined in desirable direction several characters except number of eras/plant for each seasons , ear length for fall season and number of grain / row for spring season .The dominance gene action was more effective than the additive gene action for all characters in the both season .The narrow – sense heritability values were ranged between 2.9% and 25.2%for number of grain / row and leaf area, respectively in the fall season, while in the spring season, ranged between 6% for number of grain /row and 15.4% for number of rows /ear and weight of 300 grain ( gm ) . The broad sense of heritability values were ranged between 72.2% and 95.3% for ear length and yield of single plant for the fall season, respectively While in the spring season they ranged between 73.9% and 97.3% for leaf area and yield of single plant , respectively .The average degree of dominance was higher than one for all characters . which revealed over dominance .

A field trial was conducted at farm of Qaim region silty caly soil to study the effect of space between plants and nitrogen fertilizer on growth and yield in Qaim .The objective of research is to determine the response of corn ( Booheth 106 ) in autumn season of 2005 fertilizer using three levels (80, 160, and 240) kg N/ha and using three spacing between hills (15, 25, and 35) cm, as sup plot. These factors( 3*3 ) were input in split plot design with three replication, seeds were planted at 20 july in rows 0.70 m spacing between. Nitrogen application incrased leaf area. Plant height and yield signifcantaly. So that 25 cm between hills gave the best means of these characteristics and resulted height rate of yield with using 160 and 240 kg N/ha.

This experiment was carried out during winter season of 2000 - 2002. The objectives were to determine the effect of different rates of seeding and row spacing on the yield of grain and straw of triticale. A split - plot arrangement with R C B D of four replications was used. Seeding rates, 32, 64, 100, 140, 200 kg/ha, and row spacing: 10 and 30 cm were used. The results showed that rates of seeding had significant effects on spike length. The seeding rate of 64 kg/ha produced the longest spike (9.3 cm), while the shortest was in the treatment of 200 kg/ha (7.8 cm). The combination treatment of 30 cm and 32 kg/ha produced the longest spike (9.8 cm), while the shortest was in the combination of 10 cm and 200 kg/ha (7.1 cm). There were no remarkable differences in the grain yield due to row spacing, but rate of seeding had significant effects. The seeding rate of 100 kg/ha gave higher grain yield (11.78 t/ha) unlike the treatment of 200 kg/ha which gave lowest grain yield (7.2 t/ha). The rate of seeding showed significant differences in straw yield. The rate of 100 kg/ha gave higher straw yield (12.41 t/ha) as combined to 200 kg/ha which gave the lowest (8.77 t/ha). However, the interaction of row spacing with rate of seeding was not significant, indicating that rate of seeding gave the same response in regardless of row spacing in both grain and straw yields. It was concluded to recommend the rate of seeding 100 - 140 kg/ha with any row spacing 10 - 30 cm between rows for triticale to have higher grain yield.

Field experiment was carriedout in the seasons of 2002 – 2003 and 2003 – 2004 at the fieldsof Saqlawala Zone to study the effects of gigh levels from nitrogen fertilizer of (80 – 160 – 240) kg N / ha on growth, yield components, grain yield of triticale, the experiment was designed according to R.C.B.D. with four replication. Significant differences were found for all characteries in two seasons. The highest plant height, number of tillers, ieaf area and ieaf area index of 120 day, 132.19, 241.47, 125.15 and 3.29 respectively was obtained from treatment (240) kg N / ha and aiso give the maximum numder of spikes, numder of graim per spike, weight of thousand grains / g, biological yield, grain yield and harvest index 201.75, 76.05, 38.93 gm, 13333.07 kg / ha, 4600.48 kg / ha and 34.92 % respectively for both seasons 2002 – 2003 and 2003 –2004.
