Farm-Based Environmental and Economic Impacts of the Drip Irrigation System

Drip irrigation has received considerable attention from policy makers, researchers, and economists for its ability to contribute significantly improvements to water resource development, agricultural productivity, economic growth, and environmental sustainability. In this paper, the impact of drip irrigation has been studied on a farming system in terms of environmental and economic conditions using the developed Trickle Irrigation System Design Modeling (TISD). The environmental conditions included soil type, land topography, climate zones, water sources, their quality, and the farm dimensions. The economic conditions comprised of real and nominal interest rates, raw land price, and the energy and labor escalation rates. The study considered only the Benefit-Cost Ratio (BCR) to indicate the impact of environmental and economic parameters on the use of the drip irrigation system. The study used tomato-sesame as a crop rotation (line-source) and citrus as a long-life tree (point-source). Some parameters such as soil type, land topography, and water quality had a significant impact on the BCR.

The present experiment on Performance evaluation of drip irrigation system and profitability analysis of leafy vegetables under polyhouse was conducted to study the performance parameters of the drip irrigation systems relating to crop performance. This was done by taking existing drip tapeline, new drip tape line and new inline drip irrigation system under the Polyhouse at the college of Agricultural Engineering, Kandi, Sangareddy, Telangana during the year 2018. Profitability of five green leafy vegetables viz. Palak, Sorrel, Methi, Amaranths and Coriander was also evaluated. The results reveal that the three drip line systems in-line got more uniform coefficient of 98% followed by new drip tape with 96% and preinstalled drip tape with 95%. Among the five green leafy vegetables methi has recorded highest gross (306000Rs acre-1) and net returns (285833) and benefit cost ratio (14.2) followed by Palak, Sorrel whereas Amaranthus has recorded lowest benefit cost ratio (7.6). In terms of performance characteristics, drip tape and in line system performed better in maintaining uniformity discharge and the designed drip irrigation operated excellently. Methi, Palak ad sorrel found suitable and profitable in polyhouse where year- round cultivation of vegetables is feasible compared to open field in which crop establishment was very poor and could not be raised successfully due the heavy rains and growth characters of the leafy crops.

Tomato trials with black plastic mulch, drip irrigation, and fertigation were conducted on a Lily sandy loam soil of medium fertility at Crossville, TN in 1990 and 1991. 'Mountain Pride' tomatoes were fertilized with a broadcast preplant application of 1120 kg ha–1 of 10-4.4-8.3 fertilizer with and without combinations of black plastic mulch and weekly applications of 0.64 cm of water for 12 weeks through drip irrigation. Three black plastic mulch and drip irrigation treatments supplied additional nitrogen and potassium fertilizer through the drip irrigation system. Yields were increased by use of black plastic mulch and by trickle irrigation in 1991. However, additions of fertilizer through drip irrigation had no effect on yields.

The Impact

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.

Benefit Cost

A field experiment was conducted with the purpose of testing and evaluating the use of a closed-loop, real-time control system which was developed by (Elnemr M.K., 2017) for application to a poor hydraulic performance drip irrigation system with sandy loam soil cultivated with cucumber crop. This control system collects soil moisture data through three sensors distributed along each third of the lateral. The control system was based on calculating the average soil moisture content (MC) of the three readings and using it as an indicator to start or stop irrigation process according to the requirements of the plant. The control system will start the pump after the depletion of allowed MC percentage of available water which is one of the required inputs to operate the control system. The irrigation process continues until reaching the field capacity (FC) value. The study compared two management methods for the irrigation system. First one was using the proposed control system (Aum) and the other one was manual operation based on calculating water requirement from climatic data (Clm). Using the proposed control system led to increase cucumber crop production by 23.8% of Clm productivity. The control system led to save water and seasonal irrigation time. This led to increase water productivity and energy use efficiency of Aum if compared to Clm by 41.71% and 110% respectively. Despite the added cost to the irrigation system because of the control system, the benefit/cost ratio for Aum was higher by 24.39% due to the decrease in energy and labour costs in addition to the increase in crop production. The study recommended using the researched control system with drip irrigation systems which show poor hydraulic performance to reduce negative effects on crop production and to reach more efficient use for both water and energy with keeping the opportunity to increase benefit/cost ratio. Further studies should be done on the system with drip irrigation system that work under acceptable ranges of hydraulic performance. Also, further studies should be done to investigate the most effective and suitable distribution of the sensors along lateral.

Spring Season

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 .
