Effect of Ethephone, Zinc and Boron on growth and Yield of Cucumber (Cucumis Melo var. Flexuosus) Cultivated in Plastic Houses and The Economic Feasibility From That

Abstract

A field experiment was carried out in one of the plastic houses belonging to the College of Agriculture, Al-Qasim green University to Studying the possibility of cultivating cucumis melo var. flexuosus inside greenhouses to improve growth and yield using microelements and ethephon. Microelements (Zn + B) at a concentration of 250 mg/L -1 and the growth regulator Elathyphon at a concentration of (2.5, 1.5, 0) ml/L -1 were used as a spray on the shoots. A factorial experiment was applied with the split plot system and randomized complete block design (RCBD) according to the least significant difference (L.S.D) test under the significance level of 0.05. The results were as follows: The interaction between (Zn + B) had a positive and significant effect on indicators such as leaf area 206.88 dm-1, number of female flowers 22.33flower-1, and the total yield 4327 kg, the percentage of nitrogen, phosphorous and potassium in the leaves was 0.6733, 2.691, 2.927, and the percentage of zinc and boron in the leaves was 19.626,14.282.The yield of one plant and the weight of the fruit 2575.5 g, 121.44 g, respectively. As for the interaction between Zn + B + 1.5, a significant effect on leaf area trait 239.91 Number of female flowers 26.33 flower-1, Total yield 5494 kg The percentage of PK in leaves 0.7233,3.080 and the percentage of boron in leaves 14.560 while the yield of one plant 3270.4 g

Effect of Activation of Cucumber Seeds with Different Concentrations of Zinc under Different Soaking Periods on Growth and Yield Characteristics (Cucumis sativus L.)

“…6 showed that the soaking with the highest concentration of zinc gave the highest rate of yield per plant amounting to 1.74 kg plant -1 , and the concentration of 8 mg L -1 of zinc was superior to the control treatment as it gave an average of 1.16 kg plant-1 while the comparison treatment was recorded The lowest rate was 0.98 kg plant -1 . This result agrees with [30] who found an increase in plant yield with an increase in zinc concentration. The results of Table 6 demonstrated that the 18-hour soaking treatment was significantly superior by giving the highest plant yield of 1.45 kg plant -1 over the two treatments, while the 6-hour soaking treatment recorded the lowest rate (1.12) kg plant -1 .…”

Studying the Effect of Field Capacity on Some Growth Indicators for A Number of Local Genotypes of Snake Melon(Cucumis melo var. flexuosus, Faqqous)

“…Its fruits are eaten fresh or used in pickles and salads. It was mentioned [1] that cucumbers are grown in Iraq in two loops in open fields (spring and autumn), as well as in greenhouses under tunnels, and in greenhouses .The interest in the production of this crop has increased recently due to the increasing demand for it by local markets, especially during the summer because it is one of the plants that can withstand high temperatures and its fruits continue to hold at high temperatures, while the fruits of the cucumber plant Cucumis sativu L because it is affected by high temperatures. More than a cucumber plant cucumber [2].…”

“…More than a cucumber plant cucumber [2]. [1] He indicated that a cucumber plant bears staminate flowers and female pistillate flowers separately on the same plant, and the predominant pollination is cross-pollination by insects availability of water in the appropriate quantities for the crop is one of the very important factors affecting growth and production , Water studies are considered one of the most important topics that concern the world at the present time and occupy their minds in the future because of their great importance in various areas of life, as well as the sharp decline in water resources in many regions of IOP Publishing doi:10.1088/1755-1315/1158/4/042005 2 the world. Therefore, researchers have to rationalize or direct the use of water [3].…”
