This study was conducted to investigate the effect of bacterial bio-fertilization A. chroococcum and P. putide and four levels of compost (0, 1, 2, 3) tons.h-1 on the leaves content of N.P.K elements. The experiment was carried out in one of the greenhouses of the College of Agriculture - University of Al-Qadisiyah during fall season 2018-2019. It designed in accordance with the Randomized Complete Block Design (RCBD) with three replicates in sandy loam soil. The means of treatments were compared with the least significant difference (LSD) at (5)% probability level. The results present that the treatments of A. chroococcum, P. putide and compost at (3) tons.kg-1 significantly increases the leaves content of K.P.K compared to all other treatments in the flowering stage (4.970, 0.5000, and 4.930) mg.kg-1, respectively. This treatment was followed by the effect of the treatment of A. chroococcum and compost at (3) tons.kg-1, which increases the values of all traits except the leaf content

To maintain the body on its metabolic activities, including catabolic and anabolic processes, it needs tools. Insulin, thyroid–stimulating hormone (TSH), growth hormone (GH) and other hormones are considered the tools that contribute to regulate metabolism in living organism. The studies that interest in that scope and applied on ruminants are too scarce, therefore the current research has studied the effect of levels of dietary protein and probiotic additives (live Saccharomyces cerevisiae more than 3.0×1013 CFU and bacillus subtilis more than 4.0 ×109 CFU) on serum insulin, TSH and growth hormones concentrations in Awassi lambs. In this study 16 lambs were divided to into four groups. In the first group lambs were fed concentrate (12% crude protein, CP) without probiotics, in the second group lambs were fed the same diet plus 1 kg/ton of probiotic, in the third group lambs were fed concentrate diet (14% CP) without probiotics, and in the fourth one lambs were fed the same diet plus 1 kg/ton probiotic. Wheat straw was offered to all lambs adlibitum. The main results have shown that increasing CP level from 12 to 14% decreased (P<0.01) serum insulin concentration from 10.52 to 7.29, without affecting serum concentrations of both TSH and GH. Addition of probiotic had no effect on serum concentrations of all hormones. Regarding the interaction effect between level of dietary CP and addition of probiotic, results revealed that higher serum insulin concentration (P<0.05) was associated with blood samples collected from lambs fed 12% CP without probiotic. Higher (P<0.01) serum TSH concentrations detected in blood samples collected from lambs fed 12% CP without probiotic and 14% CP with addition of probiotic. In conclusion, only insulin levels were significantly affected by increasing CP levels, but interaction with addition of probiotic affected both insulin and TSH levels.

A field experiment was carried out in the field of the College of Agriculture / University of Wasit, located on longitude 45o 50o 33.5o East and latitude 32o 29o 49.8o North, in Spring season of the agricultural season 2019, in order to estimate the water consumption of potato crop using SWRT technology and under the drip irrigation system. The experiment was designed according to Randomized Complete Block Design (RCBD)
with three replications and four treatments that include of the SWRT treatment (the use of plastic films under the plant root area in an engineering style), and the treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and the control treatment . Potato tubers (Solanum tuberosum L.) var. Burin was planted for spring season on 10/2/2019 at the soil depth of 5-10 cm.
The highest reference water consumption for the potato crop during the season was calculated by Najeeb Kharufa, which was 663.03 mm. The highest actual water consumption for the potato crop during the season for the control treatment was 410.1 mm. The results showed increase in the values of the crop coefficient (Kc) in the stages of tubers formation and tubers filling stage as compared to the vegetative and ripening stages, ranged from 1.37-1.92 for the two stages of tubers formation and tubers filling. The SWRT treatment gave the highest water use efficiency during the season, was 3.46 kg m-3 .

Investigating the effect of urea and nano-nitrogen fertigation and foliar application of nano B and Mo on growth and yield of potato Solanum tuberosum L. [Rivera-A]. The study was conducted in a private farm located in the Al-Taleah area - Babylon governorate. The experiment consisted of (12) treatments consisting of separated fertigation of nano nitrogen (25% N) and urea (46% N), single treatments of leaf spraying of nano Mo (5%), Nano B (9%), nano-binary combinations (Mo+B) and (U+ Nano Mo), (U+Nano B), Nano (N+Mo), Nano (N+B), and tricombination treatments of (U+Mo+B), Nano (N+Mo+B) additional to the control treatment. Randomize Complete Block Design (RCBD) and one way simple experiment with three replicates. Fertilizers were applied at levels of 40 liters h-1 of Nano-N fertilizer (25% N) and 300 kg h-1 urea fertilizer (46% N). They were sprayed early in the morning after (40) days after planting four times. Two weeks is the period between an application and another according to the recommendation of (1) kg h-1 nano-fertilizer of (B) and (500) g h-1 of Mo. Fertilizers were injected and sprayed at (10, 20, 30 and 40)% of the total amount of the fertilizer were applied as the first, second, third and fourth applications, respectively. Some growth traits were tested including the chlorophyll content in the leaves, the total dry vegetative yild, the soft tubers yield, and the biological yield, proteins and ascorbic acid yield compared to the control (spray water only). The results of the Duncan test showed a significant increase in most of the studied traits of nano-tricombination (N+Mo+B) in the fresh tubers yield, dry vegetative yield , the biological yield, starch yield ,the total protein and ascorbic yield (37.53, 1.799, 8.138,4.152 , 481.3and 653.8 meg ha-1) respectively .compare to control (21.58 , 0.890, 4.463 ,2.323 , 366.1 and 215.5 meg ha-1) respectively.

A field experiment was carried out in the field of College of Agriculture / University of Wasit, located on longitude 45o 50o33.5o East and latitude 32o 29o 49.8o North, in the spring agricultural season 2019. The experiment was designed according to Randomized Complete Block Design (RCBD) with three replication and four treatments that include each of the SWRT treatment (use of plastic films under plant root area in an engineering style) treatment of vegetal fertilizer (using Petmos), organic fertilizer (sheep manure), and control treatment. The bulk density values of soil profile for the season increased compared to their values before planting. It is noticed that the values of bulk density of soil increased with depth, ranging between 1.22 - 1.27 Mg m-3 for SWRT treatment and between 1.28 - 1.31 Mg m-3 for plant fertilizer treatment and between 1.22 - 1.32 Mg m-3 for animal manure treatment and between 1.29-1.34 Mg m-3 for control treatment. The values of saturated hydraulic conductivity of soil decreased with depth after the end of the season ranged between 0.41-0.47 cm / hour for SWRT treatment and between 0.21 -0.24 cm / hour for petmos treatment and between 0.14-0.2 cm / hour for animal manure treatment and between 0.17-0.2 cm / hour for control treatment. The rate of infiltration rate and accumulative infiltration decreased for all treatments after the end of potato growth season compared to their value before planting, and the SWRT treatment gave the highest values compared to the rest treatments.
