Almond responses to a single season of severe irrigation water restrictions

This investigation of both of irrigation system, water restriction and soil conditioners on Morengaoleifera, (surface drip irrigation, D, buried drip, BD and mini-sprinkler, MS), as well for irrigating a magic crop like Morenga (Morengaoleifera) plants. Also, this work includes different irrigation water restriction which represent two three treatments (100, 80 and 60% of calculated applied water, W1, W2 and W3 respectivly), more over threes soil conditioners (Compost, C, Farm manure, FM, Mud, M). The experiment was carried out inShalatien where it lies in the east-west of the Red sea in Egypt. Surface evaporation in this area has a paramount importance because of its aridity hot climate under the circumstances of saline irrigation water usage. The objective of the present work is to study the influences of irrigation system, water restrictions and soil conditioners onmorphological and chemical characterizes of Moringa, for that,the following measurements are taken Trunk Diameter, Pods Tree Quantity, Seeds Yields (g) per tree, Weight per 1000 seeds (g), oil yields per tree (g), oil Yields per/ Acer (kg), chlorophyll A- B, total chlorophyll, carotenoids, Total carbohydrates, vitamin C,Nitrogen, Calcium, Fe and zinc content of Moringaoleifera plants in addition to Water use efficiency, cost analysis, energy analysis in two studied seasons, (2017-2018/2018-2019). Results show that the most positive influence of irrigation is buried irrigation, drip irrigation and mini-sprinkler respectively, due to the saved water from losses by evaporation under drought conditions. And the most positive influence of water restrictions treatments is 100, 80 and 60% respectively, but the in many measurements the differences between both of 100 and 80% of applied water is not significant, so its more economical to approve 80% of applied water under buried drip irrigation, which means about 20% of applied water can be save.

Irrigation Network

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

Efficient Water Use

The deficit of the irrigation water requires irrigation technologies with more efficient water use. For cucumbers, the most suitable is the drip irrigation technology. For establishing of the appropriate irrigation schedule of cucumbers under the soil and climate conditions in the village of Chelopechene, near Sofia city, the researchеs was conducted with drip irrigation technology, adopting varying irrigation schedules and hydraulic regimes - from fully meeting the daily crops water requirements cucumbers to reduced depths with 20% and 40%. It have been established irrigation schedule with adequate pressure flows in the water source, irrigation water productivity and yields of in plastic unheated greenhouses of the Sofia plant.
