Drip irrigation is one of the essential, advanced and innovative irrigation methods over surface irrigation. In view of this, an experiment was conducted to study the efficiency of drip irrigation system over surface irrigation in onion during Rabi 2013-14 and 2014-15 and Kharif 2014 and 2015. The results revealed that drip irrigation system performed superior over surface irrigation system in terms of superior plant morphology, yield and quality of bulb. Drip irrigation recorded maximum plant height (66.37 cm & 61.88), number of leaves (9.23 & 8.00) and neck thickness (1.62 cm & 1.30 cm) in both Rabi and Kharif seasons. The bulb equatorial and polar diameter, higher gross yield as well as marketable yield obtained in drip irrigation system. In drip, gross yield and marketable yield increased 18.16% and 24.49%, respectively over surface irrigation method and better water use efficiency and also saved 29.36% and 27.12% water during Rabi and Kharif seasons, respectively.

Low Head

The effect of plastic mulch on chickpea (Cicer arietinum L.) cultivation under low head drip irrigation systems was studied at ICAR-Central Institute of Agricultural Engineering, PFDC, Bhopal during 2018-19. Drip irrigation system was operated by placing water tank at a total water deliver height of 3 m and varied heads to 2.5 m and 2.0 m to find out the value of coefficient of uniformity under these heads. The experimental treatments consisted in five levels by varying irrigation methods: Flood irrigation, irrigation with drip laid on raised beds, irrigation with drip laid on raised beds covered with black mulch, irrigation with drip laid on raised beds covered with silver mulch and irrigation with drip laid on raised beds covered with white mulch. Growth and yield parameters of chickpea viz., plant height (cm), number of branches per plant, plant dry matter (g/plant), effective nodule per plant and nodules dry weight (mg/plant), number of pods per plant, 100 seed weight, seed yield (kg/ha) and harvest index were highest under silver plastic mulch laid on raised beds, irrigated with drip as compared to black plastic mulch and white plastic mulch treatments. Lowest growth and yield parameters were recorded in the flood irrigated treatment. Water Use Efficiency was highest under silver plastic mulch (17.21kg/ha mm) and lowest under flood irrigated condition (3.74 kg/ha mm). Net returns were higher in the treatment under the silver mulch (Rs/ha 77939) and followed by black mulch (Rs/ha 67179) with lowest net returns in the flood irrigated condition (Rs/ha 32690).

Experiments were conducted to evaluate the yield response of tomato (Lycopersicon esculentum Mill.) to P, either preplant-incorporated or injected through the drip irrigation system, on soils with low, high, or very high soil P content. Fertilization through the drip irrigation system (fertigation) was more efficient than preplant incorporation of P for soil that tested low in P (9 mg·kg–1 Mehlich-1 P). On soil testing low in P, marketable yield response to preplant soil P application rates (0 to 100 kg·ha–1) was maximum at 61 kg·ha–1 P according to the linear-plateau model, but 37 kg·ha–1 P according to the quadratic-plateau model. The lower value is about one-half the P recommended by Univ. of Florida for low-P soils. On soil testing high in P (48 mg·kg–1 Mehlich-1 P) the linear-plateau model predicted a maximum yield of 72.8 t·ha–1 with 25 kg·ha–1 P. The Univ. of Florida recommended no P for that soil. On soil testing very high in P (85 mg·kg–1 Mehlich-1 P), there was no yield improvement with P fertilization.

Abstract The experiment was conducted in field during the season 2020-2021 at The Al-sayade Research Station of the College of Agriculture/University of Kirkuk, and aimed to study the impact of three types of organic fertilization (without fertilization, sheep fertilizer, organic fertilizer), and three types of Emitter (GR, Turbo, Spiral ) and the interaction between them in the growth and yield of Broccoli ( Brassica oleracea Var.italica ) and the evaluation of the Drip Irrigation System. A factorial experiment was carried out according split split – plot design of the Random Complete Block Design R.C.B.D and obtained data was statistical analyzed by using SAS system and Duncan multi –Range test at the probability level of %5 used to compared among the mean of treatment. The results showed that organic fertilization of sheep fertilizer gave a significant increase in the height of the plant 66.27 cm. The H (250g.d-1 in four stages) fertilizer adding showed a significantly Superiority for traits of the yield of plant and total yield of plant (902.84 g plant-1 and 45.142 ton ha-1, respectively). However, the treatment without fertilization has given a significant increase of total chlorophyll ratio to 25.44 mg. g-1.Turboemitter recorded a significant increase in the height of the plant 67.233cm. whereas, the GR emitter showed a significant increase the total chlorophyll ratio by 25.830mg g-1and superior in percentage of dry material in main head recorded by %12.694. The interaction between H fertilizer and Turbo emitter, had significantly differences of the most of the qualities traits were studied. When evaluating the drip irrigation system, it noted the superiority of the GR emitter treatement was gave the lowest plants the Coefficient of Variation 0.051 % with the highest absolute field emission uniformity reach to 98.84%, the highest efficient water distribution with 98.08% and the lowest water consumption 43.17mm.

Trickle irrigation is one and only of the water saving, progressive and advanced irrigation methods over gravity irrigation. In the point view of this, the research was lead to study the efficiency of Trickle irrigation over gravity irrigation in growth and yield of garlic in case Rabi & Kharif periods, wonka kebele, Ethiopia. The results indicated that trickle irrigation was well achieved greater over gravity irrigation method in terms of greater crop morphology, yield and quality of bulb. Trickle irrigation method documented maximum crop height (67.77 cm & 62.85), amount of leaves (10.25 & 8.00) and neck thickness (1.63 cm & 1.40 cm) in both Rabi and Kharif periods. The bulb equatorial and polar diameter, higher gross product in addition to marketable product achieved in trickle irrigation method. In trickle irrigation method, the gross product and marketable product improved by 12.54% and 22.63%, respectively in Rabi periods over gravity irrigation method and better water use productivity & as well saved 29.40% & 29.20% water for the period of Rabi & Kharif periods, respectively.
