Freshwater Resource

Globally, agriculture sector uses major share of available freshwater. Pakistan is an agricultural country and its major economy depends upon the agriculture sector. In Pakistan, freshwater sacristy rate is increasing due to poor sanitation and water management system, increase in population and food demands, and use of fresh water flood irrigation system to irrigate the agricultural land. This ultimately poses harmful effect on the economy of country. About 73% of freshwater resource is consumed for the irrigation purpose in Pakistan. The increase in population and the food demand is an impetus to adopt drip irrigation system at large in the country. In such a scenario, controlled drip irrigation system serves the suitable technique to limit the water supplied to the crops at regular interval for agriculture, and replaces the flood irrigation system. Besides ordinary drip irrigation system, the controlled drip irrigation system monitors and controls the soil moisture and temperature of the crops using sensors and actuators. This study is aimed at designing and installation of controlled drip irrigation system for crop fields at Nasarpur, Sindh, Pakistan. It was expected that agricultural sector will become more productive by effectively using the fresh water resources. The study has shown that converting conventional irrigation into controlled drip irrigation has saved freshwater to a greater extent and marginal excessive use energy used in pumping and the control system. On the other hand it has also minimized the energy usage for pumping fresh water through large tube wells.

AbstractA study was conducted to design productive, profitable, irrigation water¸ nitrogen and energy use efficient intensive cereal systems (rice-wheat; RW and maize-wheat; MW) in North-West India. Bundling of conservation agriculture (CA) with sub-surface drip irrigation termed as CA+ were compared with CA alone and conventional tillage based and flood irrigated RW rotation (farmer’s practice; ScI). In contrast to conventional till RW rotation which consumed 1889 mm ha−1 irrigation water (2-yr mean), CA+ system saved 58.4 and 95.5% irrigation water in RW and MW rotations, respectively. CA+ practices saved 45.8 and 22.7% of irrigation water in rice and maize, respectively compared to CA with flood irrigation. On a system basis, CA+ practices saved 46.7 and 44.7% irrigation water under RW (ScV) and MW (ScVI) systems compared to their respective CA-based systems with flood irrigation (ScIII and ScIV). CA+ in RW system recorded 11.2% higher crop productivity and improved irrigation water productivity by 145% and profitability by 29.2% compared to farmers’ practice. Substitution of rice with maize (MW system; ScVI) recorded 19.7% higher productivity, saved 84.5% of irrigation water and increased net returns by 48.9% compared to farmer’s practice. CA+ RW and MW system improved energy productivity by 75 and 169% and partial factor productivity of N by 44.6 and 49.6%, respectively compared to ScI. The sub-surface drip irrigation system saved the fertilizer N by 20% under CA systems. CA+ in RW and MW systems recorded ~13 and 5% (2-yr mean) higher profitability with 80% subsidy on installing sub-surface drip irrigation system and similar profitability without subsidy scenario compared with their respective flood irrigated CA-based systems.

Alternative Irrigation

Egypt produces approximately 2.4 million m3 of secondary treated wastewater (TWW) annually, used for irrigation directly or indirectly by blending with agricultural drainage water (BDW). The annual re-use of (BDW) is approximately 4 million m3. The safe and efficient use of marginal water (BDW and TWW) is a core objective of this study which has been operating from 1997 to date. After six growing seasons the main results can be summarized as follows: Maximizing crop production: TWW can be used for high production of oil crops (canola, soybean sunflower or maize) compared to fresh water, while BDW can be used for high production of tolerant crops (cotton and sugar beet). Crop quality: using marginal water increases the concentration of elements (Pb, B, Ni, Co) in all crops but these elements were under critical levels (there were no toxicity hazards). It is better to use alternative irrigation with fresh water under a drip irrigation system to maximise crop production and minimise the adverse effects of such water in field crops quality. Soil pollution and salinity build up: A drip irrigation system under alternative irrigation by fresh with TWW or BDW reduces salinity build up risks and the levels of elements (Pb, B, Ni, Co) in soil compared to re-use marginal water. Soil pathogens: using marginal water slightly contaminated the soil with total faecal coliform (TFC), mites, shigella and salmonella Plant anatomy: No great changes in anatomical disturbance where induced in different structures of plants which were reduced at maturity stage. Primary guidelines for re-using marginal water: From obtained results it can be recommended to use marginal water with salinity content ranged between 1.1 to 3. 64 dS/m, and elemental contents (Pb 3.0–3.51 ppm), (B 0.05–1.67 ppm), (Co 0.04–0.07 ppm), (Ni 0.08–0.15 ppm) for safe (field, vegetable and medicinal) crops production. Reuse bio solids for crop production: Sewage sludge produced from treated wastewater can be safely used by mixing with rice straw (1:1 w/w) for economic crop production and saving mineral fertilisers. General conclusion: In the North Nile Delta, marginal water (especially BDW) can be safely used without significant negative impact on the environment, but there is a need for multi-disciplinary, long-term research to investigate irrigation with marginal water in terms of the environment, public health and agricultural productivity.

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 .
