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 .

A field experimentt has been carried out in the Autumn season of 2017 in one of the fields of the College of Agriculture - University of Qadisiyah to determine the response of the potato (Solanum tuberosum L.) to the fertigation with nano fertilizers of macro elements NPK on the growth and yield of the potato cultivar Arizona under drip irrigation system. The experiment has included 9 treatments of fertigation single Nano N, P, K, di combination nano (N+P), (N+K), (P+K), tri nano (N+P+K) and conventional fertilizers (NPK20:20:20) In addition to the comparative treatment, according to design of RCBD and one way simple treatment with 4 replicates .
Fertilizers have been injected with levels of addition of 40L h-1 of nano nitrogen fertilizer 25%N, 10 kg h-1 of nano phosphorus fertilizer 25% P and 20 kg h-1 of nano potassium fertilizer 35% K and 300 kg h-1 traditional fertilizer Tron (NPK 20:20:20) ) in four batches 10%, 20%, 30% and 40% of the quantities of fertilizers added to the first, second, third and fourth batches respectively. The growth parameters tested are plant height, chlorophyll content in leaves, vegetative dry matter yield, soft tubers yield, biological yield, dry tubers yield, starch, protein , The results of the Duncan test under a significant level of 0.05 showe that the following fertigation of nano (N+P+K) give has given the highest rate of vegetative qualities and the quality of all yield and significantly exceeded the di combinations and individual fertigation in some traits (plant height and chlorophyll content SPAD.higher nano(N+P+K) combination in the vegetative yield, the soft tubers yield, the biological yield, dry matter yield of tubers, the total yield protein and starch (2.148, 48.221, 11.395, 9.246,843. 871 and 6.355 Mg h-1) .

This study has been conducted at the city of Diwaniah located 180 km south of Baghdad to examine the effect of potassium and copper floral application on the growth and yield of potato plants (var.Burren) during the 2015 spring season. Factorial experiment has been carried out in Random Complete Block Design (RCBD) with three replications and Nine treatments have been used which have three potassium concentrations at 0, 3000, and 6000 mg KL-1 designated respectively and three copper concentrations at 0, 2.5, and 5 mg CuL-1 designated respectively in addition to their interactions. The treatments are applied at three different timeframes which are 45 days after sowing, 15 days after the first spraying, and 15 days after the second spraying. Vegetative growth have been collected at the maturation stage then dried to obtain dry weight and N, P, K, and Cu have been estimated in plant leaves. Tubers are harvested to measure number and yield/plant, tubers average weight, total marketing yield and yield. The obtained data are statistically analyzed and averages are compared according to the least significant differences (LSD) at 5% level of significance and the results were as follows:
The yield components which include tubers number as compared with the control treatment.
Copper foliar application significantly increase vegetative traits of the yield. The K2 treatment has given the highest significant increase of main stem vegetative growth of the components which include tubers number as compared with the control treatment.
The interaction treatments have given a significant result in terms of the both the vegetative and yield traits where K2* Cu2 give the most significant increase in term of vegetative growth while K2* Cu1 significantly increase the plant height and K1* Cu2 significantly affect the number of leaves. As for the yield component, K2*Cu2 show to have the most significant result in all traits under investigation.
Finally, in terms of affecting leaf content of N, P, K, both treatments and their interactions especially K2*Cu2 have a significant impact as compared with the control treatment where the highest the concentration is the highest the impact will be..

To find out the effect of the manure (plant residues) in the growth and yield of potatoes in calcareous soil conducted filed experiment has been in a field located in physical education areas–Baghdad University- Jadiriyah campus in fall season in 2015-2016 in a LoamySand soil, the study included two factors the first factor includes four sources of manure O0(without adding) O1(paulty) O2(wheat straw) O3(palm fronds) with volume is 30 Tan h-1 and the second factor includes the application of three levels of the chemical fertilizer M0(without application) M1(120 kg N +60 kg P+200 kg K) M2(240 kg N+120 kg P+400 kg K) layed out in a (RCBD) with three replication, manures and the phosphate fertilizer are added before two weeks of planting. The seeds of potatoes class are plantal (Desiree) in 22 September 2016, by adding the nitrogen and the potassium fertilizer in three equal times in 21,45,70 days after planting. At the maturity stage are measurements of plant height, number of main stems and the maturity stage reaped of the vegetative parts and calculated the dry weight of the shoot on 22January 2016 tubers are taken off and measure the total yield of tubers. The results show a superiority of the treatment of poultry of out was performed other than the treatments of wheat straw and palm fronds as indicators of plant height 68.00cm, the number of main stems 3.63 stem plant-1and the dry weight of shoot 7.04 Ton h-1and the total yield of tubers is 49.94 Ton h- Wheat straw treatment has given lower values in the studied indicators measuring treatment of poultry and palm fronds its gave plant heights of 57.40 cm and a number of main stems 2.50 stem plant-1,the dry weight of shoot 5.70 Ton h-1 and the total yield of tubers is 40.92 Ton h-1The treatment of the mineral fertilizer M2 which has the superiority in studied indicators Measuring this paperwork M0 and M1 given plant height 69.37 cm and the number of main stems 3.80 stem plant-1and the dry weight of shoot7.04 Ton h-1 and the total yield of tubers is 50.09 Ton h-1.Intergration of organic fertilizer and mineral fertilizer application M2O1has given plant height 75.40 cm and the number of main stems 4.60 stem plant-1and the dry weight of shoot7.32Ton h-1 and 57.22 Ton h-1 the total yield of tubers..
