Under the effect of water stress, biological and physiological processes can be decreased and followed by a reduction in growth and production of crops. Molybdenum plays important role in abiotic stress tolerance as well as support the growth and production of mung bean. For this purpose, a field experiment was conducted where Mo was used in four concentrations (0,15, 30, 45 mg L-1) as seed soaking and foliar application on mung bean growing under three irrigation intervals (irrigation each 4, 8 and 12 days), a split plots arrangement in RCBD was used where the irrigation intervals occupied the main plots while Mo concentration randomly laid in sub plots. The important results of the current study were that Mo (e.g. 45 mg L-1) gave the highest leaf area (1435.34 cm plant-1), and Mo at 15 mg L-1 gave the highest mean of plant dry weight (223.00 g plant-1) as for the yield components, the concentration 30 mg L-1 gave the highest mean of number of pods per plant (45.28 pod plant-1) while the concentration 15 mg L-1 achieved the highest mean of number of seed per pod (7.49 seed pod-1). The combination treatment of 45 mg L-1 and irrigation each 4 days led to obtain the highest mean of growth characteristics as well as yield traits with exception of weight of seed as it got higher mean when plants were treated with 45 mg L-1 and irrigated each 8 days (4.50 g). It can be concluded from the current study that diverging irrigation intervals causes a great reduction in field performance of mung bean while the application of Mo enhanced some of the growth and yield traits. It can be recommended to use this element at different concentrations in order to improve growth and yield of different field crops.

A field experiment was conducted at the experimental farm, College of Agriculture, Al-jadrea, Baghdad, Iraq during spring season of 2016 to study the effects of foliar application with yeast extract on grain yield, yield components of five sorghum cultivars. The layout of the experiments was split plot design with three replicates , The five cultivars it is kafeer, bohooth 70, rabih, inkath and local, occupied the main plots while yeast extract concentrations 0, 5, 10,15 gr L-1 occupied the sub-plots. Results of this experiment are summarized as follows: number of seeds per head, seed yield increased with the increase of yeast extract concentrations and the best concentration in most of yield characters was 15gm L-1. The cultivar buhooth 70 was superior in 1000 seed weight, seed yield while the cultivar Rabih was superior in number of seeds per head.

A field experiment was carried out in the spring and autumn season of 2016 in fields of Field Crops Department, Faculty of Agriculture, University of Anbar,( Abu Gharib), in soil with a clay-silty texture, to determine the effect of foliar application with three concentrations of Boron; 0, 90, 180 mg L-1, and Salicylic acid; 0, 150 and 300 mg L-1, in the productive and quality traits of two mung bean genotypes, local and Indian cultivars. The experiment was took place using Split-Split Plot arrangement in randomized complete block design, where genotypes occupied main plots while salicylic acid concentration occupied sub plot and Boron concentration in the sub-sub plot. Obtained results were summaries as follow:
The concentration of 90 mg B L-1 in the two seasons showed the highest average fertility rate in pods and seeds with 696.90 and 789.70 kg-1, and protein about 188.50 and 191.30 kg-1 respectively, Concentration of 180 mg B L-1 in the same season achieved the highest mean weight of 100 seeds and protein ratio in seeds 25.15%. Boron did not significantly affect the length of the pod in the two seasons.
The concentration of 150 mg SA L-1 in both seasons gave the highest fertility rate in the pods as 69.76 and 77.53%, and the highest average yield of the seeds with 698.4 and 760 kg-1 respectively, and recorded in the spring season the highest weight for 100 seeds, In the protein content about 185.50 kg e-1, and the concentration of 300 mg SA L-1 exceeded in the autumn season in the number of seeds by pod. The genotypes differed significantly in the studied traits except for the percentage of protein in the seeds and both seasons. The local genotype showed the highest mean number of seeds by pod and seed yield by 789.20 and 791.5 kg e -1, and protein with 210.20 and 187.30 kg-1, While the Indian genotype in both seasons showed the highest average length of pod and 100 seed weight 6.74 and 7.02 g, for the two seasons respectively. The effect of triangular interference (genotype * salicylic * boron) in the two seasons was significant in the weight of 100 seeds, seed yield, protein content and yield. The local genotype with spraying with concentrations 90 mg B + 150 mg SA L-1 achieved the highest mean yield of 988.6 and 1092.9 kg e-1 for the seasons respectively and for the protein yield in the autumn season 239.9 kg h-1 protein Indian genotype with the same treatment spray highest protein content in seeds by 29.48%.

A field experiments were conducted during winter season of 2008-2009 at three locutions in Karkook irrigation Project , using two wheat cultivars (Sham-6 and IPA-99 ) to evaluated the effect of foliar application et Agrosoil-plex on yield and yield Components . R.C.B.D design with three replicates were used .
Three treatment (T) were used at the three locations of two cultivars as a following :
T1 = 30Kg (p20s) ha 1-applicated at sowing stage + 40kg (n) . ha which were application at three pant (1.3 at sowing stage , 1.3 at tillering stage and 1.3at Flowering stage ) .
T2= Ti+ Foliar application ( Agrosoil – plex ) at one time with rate 150 mil. Ha-1 a ttilening stage .
T3= Ti+ Foliar application ( Agrosoil – plex) at two at two time with rate 150 mil. Ha-1 at each time ( the First were at tillering and the second at booting stage ) .
The plant height , number of kernels /spike , number of spike / m , 1000 kernels weight and grain yield at maturity stage were measured .
The results revealed the Following :
There is a significant differences between the three treatments of the two cultivars between the three treatments of the two cultivars in all studied character is tics except the 1000 Kernels weight of sham -6 Cultivar only .
Foliar application (Agrosoil – plex) treatments (T2andT3) Surp aced the (T1) treatment , and (T3) treatment Surp aced the (T2) treatment in of hen Characters of the two Cultivars (T3) Treatment showed significant increased in grain yield with percentage 43-17% and 14-68% at sham – 6 and 33-97% and 16.27% of IPA-99 cultivar compared with (T1) and (T2) treatment respectively , and (T2) showed significant increased in grain yield with percentage 24.84% and 15.22% Compared with (T1) at the two cultivars Sham -6 and IPA-99 especially.

Influence of different foliar fertilizers and CO2 enrichment on growth characteristics of sweet orange transplants grown under nursery condition was investigated from Septemper 2009 to June 2011 .Three foliar fertilizers namely KNO3 ,Fe-EDDHA and ZnSO4 were used in three concentrations: 0(distilled water was used for spraying the control transplants), 5000 mg K L-1 + 20 mg Fe L-1 +15 mg Zn L-1 and 10000 mg K L-1 + 40 mg Fe L-1 + 30 mg Zn L-1. The transplants also exposed to three CO2 levels , near those of ambient air ( 0.0385 % ) ,( 0.0685 % )and( 0.0985 %) .The results demonstrated that the number of leaves, leaf area , number of shoots per transplants, stem diameter,dry weight of shoots and roots, relative chlorophyll content , leaf N content and percentage of carbohydrate in shoots were increased in transplants foliar sprayed with 10000 mg K L-1 + 40 mg Fe L-1 + 30 mg Zn L-1. Elevated CO2 level to(0.0985 %) increased number of leaves and leaf area, number of shoots/ transplants , stem diameter , shoots and roots dry weight and carbohydrate percentage in shoots .Whereas transplants grown under ambient air( 0.0385 % ) contained the highest relative chlorophyll content and N leaf content.
