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.

Background: Drip irrigation system is one of the best water application methods that have been used in the world among the other irrigation methods because of its upright and high uniformity and high-water use efficiency. Hydraulic performance evaluation is widely accepted for the evaluation of overall uniformity of a drip irrigation system. Methods: In an experimental study carried out at School of Engineering, RK University, Rajkot; hydraulic performance evaluation parameters viz., Pressure discharge relationship, Christiansen’s uniformity coefficient (CU), manufacturing coefficient of variation (CVm) and emission uniformity (EU) of non-pressure compensating emitters were calculated for 2 lph inline and 2 lph, 4 lph, 8 lph online emitter at various operating pressure of 0.8, 0.9, 1.0, 1.1 and 1.2 kg/cm2 as per American Society of Agricultural and Biological Engineers (ASAE) standards. Result: The study concluded that rated discharge of the emitter can be obtained at the operating pressure of 1.0 kg/cm2. Pressure discharge relationship revealed that discharge of the emitter upsurges as pressure rises. CU and EU were more than 95% for all the cases and they were maximum at 1.0 kg/cm2. CVm was less than 0.0200 for all the cases and it was minimum at 1.0 kg/cm2. Study concludes that all the parameter viz., CU, EU and CVm were excellent and very good categories for all emitters as per American Society of Agricultural and Biological Engineers (ASAE) standards.

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 .
