A field experiment was conducted in a gypsiferous soil with a sandy loam texture to study effect of phosphate fertilizer type and its levels on growth and yield of wheat (Triticum aestivum L.. Randomized Complete Block Design (RCBD) was used with three replications. Two types of phosphate fertilizers (TSP-Triple Super Phosphate and DAP- Di Ammonium Phosphate) were applied in six levels (0, 20, 40, 60, 80 & 100) kg P ha-1 each symbolized P1, P2, P3, P4, P5 and P6. The total plots were 36 experimental units. Nitrogen fertilizer was added to all treatments at a rate of 200 kg N ha-1 in Urea form (46% N) at sowing time and at 45 days after emergence. Potassium fertilizer was added at rate of 165 kg K ha-1 in the form of potassium sulfate (43% K). As fertilizer level increasing, the results showed significant increases in plant height, spike number, and spike weight, as well as straw and grains yield for both fertilizer types. However, increases referring to TSP fertilizer were more important than those related to DAP fertilizer in the growth criteria's and yield components.

A pot experiment was conducted at the lath–house of the Department of Soil Sciences and Water Resources, College of Agriculture, University of Baghdad during the fall season of 2013. Sandy loam texture soil was used to study the effect of mycorrhiza and potassium addition on the growth of corn plant under water stress. Three potassium levels were used control (K0), 100 (K1) and 200 (K2) Kg h-1. Mycorrhiza inoculation was used with three treatments of inoculation (without inoculation (M0), with mycorrhiza, Gloums spp. (M1) and inoculation with roots infected by mycorrhiza (M2). Three irrigation treatments were used, i. e. irrigation when 40% (W1), 60% (W2) and 80% (W3) of available water was depleted. Using a Complete Randomized Design (CRD) with three replicates per treatments, the experiment includes 81 experimental units. Compared with M0 and M2 treatments results showed that inoculation with mycorrhiza (M1) significantly increase the shoot and root dry weight which were 31.39 g pot-1 and 10.02 g pot-1 respectively, as well as leaf and root area which were 90.59 cm2 and 127.36 cm2 respectively. The addition of potassium with mycorrhiza inoculation led to mitigate the high water stress on plant growth of through their combined action. Best result was achieved due to the triple interaction among water stress, mycorrhiza and potassium, where W1M1K2 treatment showed significant increment in the dry weight of shoot system and surface leaves area reached 15.8 and 8.4% respectively, compared to W3M0K0 treatment.

An experiment was carried out at the field of College of Agriculture, University of Diyala during the autumn season 2015 - 2016 to study the effect of speed and depth of plowing on performance of rotary plow by using the machine unit consists of orchard tractor type B 2530 and mini rotary plow type 1200 in clay loam soil. The experiment was done by using random complete block design (RCBD) as a full factorial experiment with two factors. The first factor represents the plowing depths with two levels 2-4 cm and 8-10 cm, while the second factor represents the forward speed of the tractor with three levels 1.66, 3.05 and 4.35 km h-1 with three replicates.
The results showed that the depth 2-4 cm shows a higher significant effect than depth 8-10 cm of all study parameters except the volume of soil affected with less slippage percentage. The results also showed that the speed 4.35 km h-1 has a high effect comparing with speeds 3.05 and 1.66 km h-1 in all study parameters with less slippage percentage too. Meanwhile the interaction between the first speed 1.66 km h-1 with the first depth 2-4 cm showed a higher significant effect than other interactions for speed coefficient and actual field capacity with less slippage percentage. The highest productivity was on third speed 4.35 km h-1 with 2-4 cm depth 0.401 hectare h-1 and the third speed with depth 8-10 cm showed the largest volume of the soil distribution under 0.05 probability level.
From the result, we concluded that increasing the speed of the tractor has led to increase the field productivity, the volume of soil distribution, field efficiency and the coefficient of speed exploit at the lowest slippage percentage. While increase in the depth of tillage led to increase of the slippage percentage and the volume of soil distribution with decreasing in coefficient of speed exploit, field efficiency and effective field productivity. Thus the recommendation of plowing process by using the rotary plow should be at the shallow depths with high speeds to obtain the highest values of the characteristics studied.

This paper examines the short term and long term effects of changes of Iraqi dinar exchange rate versus American dollar on bilateral trade flows of some agricultural products for Iraq with its major trading partners (Syria, Jordan and United Arab Emirates) in sector of agricultural and food products trade. Accordance to the J-curve theory Johansen cointegration test was employed to analyze the long term relationship and an error correction model was employed to explore the short term effects of Iraqi dinar exchange rate level. The data set used in this study covered the period from 1995 to 2014. Agricultural and food commodity groups in this study are divided according to the SITC classification. The results showed that if the Iraq foreign trade in agricultural sector is disaggregated into specialized commodity group, there can be found only some sectors significantly connected with rate movements in the long term. The effects of exchange rate movements are less than ambiguous and cannot be generalized across the commodity groups. Theoretical short term and long term assumptions cannot confirmed in trade of most of agricultural trade of Iraq with its most important partners.
