The demand for freshwater and food is on the increase due to the rapid growth in the world’s population, while the effect of global warming and climate change poses a severe threat on water use and food security. Conventional irrigation system suffers due to an inefficient management of water and energy, while insufficient supply of water to plant increases their stress which often affects its growth and development. Hence, there is a need to increase research focus on water use efficiency in irrigation agriculture. This paper is aimed at investigating the performance of smart drip and subsurface fibrous capillary irrigation experiment for the cultivation of cantaloupe plant to increase the yield and quality of fruit while decreasing the water and energy usage. To achieve enhancement of subsurface fibrous capillary and drip irrigation system, an Internet of Things (IoT) approach was used to improve monitoring of soil, weather, plant and control of water application. The performance comparisons of both methods was evaluated in terms of water-saving in greenhouse cultivation experiment. The results obtained, shows that the smart fibrous capillary irrigation has water use efficiency of 19 g/Litre with average fruit sweetness of13.5 Brix. While, drip irrigation has 4.85 g/Litre and average sweetness of 10 Brix on the harvested fruit after 90 days of cantaloupe plant cultivation experiment. These have shown that precision irrigation through enhanced smart fibrous capillary irrigation can be used to achieve high water-saving and a good quality yield. It is expected that the research output will help to improve water-saving agriculture towards achieving food security.Keywords: Water Saving; Capillary Irrigation; Drip Irrigation; Internet of Things; Water Use Efficiency

On sandy soils, potential N contamination of groundwater resources associated with intensively managed vegetables may hamper the sustainability of these systems. The objective of this study was to evaluate the interaction between irrigation system design/scheduling and N fertilization rates on zucchini production and potential N leaching. Zucchini was planted during Fall 2005 using three N fertilizer rates (73, 145, 217 kg/ha) and four different irrigation approaches. Irrigation scheduling included surface-applied drip irrigation and fertigation: SUR1 (141 mm applied) and SUR2 (266 mm) using irrigation control system (QIC) that allowed time-based irrigation (up to five events per day) and a threshold setting of 13% and 15% volumetric water content (VWC), respectively; Subsurface drip irrigation (SDI) using a QIC setting of 10% VWC (116 mm) combined with surface applied fertigation; and a control treatment with irrigation applied once daily (424 mm). Leacheate volumes were measured by drainage lysimeters. Nitrate leaching increased with irrigation rate and N rate and measured values ranged from 4 to 42 kg N/ha. Use of SDI greatly reduced nitrate leaching compared to other treatments. SDI and SUR1 treatments had no effect on yields (29 Mg/ha). However, SDI had a 15% and 479% higher water use efficiency (WUE) compared to SUR1 and the fixed irrigation duration treatment. Application of N in excess of intermediate N-rate (standard recommendation) did not increase yield but yield was reduced at the lowest N-rate. It is concluded that combining sensor-based SDI with surface applied fertigation resulted similar or higher yields while it reduced both water use and potential N leaching because of improved nutrient retention in the active root zone.

Kinnow Mandarin

In Pakistan, orchards are irrigated using flood irrigation system that is considered sub-economical regarding water use efficiency. Considering the importance of natural water resources, there was a need to devise the method of applying irrigation water that would save water consumption, environmentally friendly and easily adopted by the growers. Thus, a research trial was conducted at Citrus Research Institute, Sargodha, Pakistan on 0.41 ha area of Kinnow mandarin. The total area was divided into two parts, half of the area was used for furrow irrigation system and the remaining half was used for flood irrigation system. Tensiometers were installed in the soil in furrow and flood irrigation system to assess the moisture condition in the soil. Irrigations were applied when tensiometer readings reached 40 centibars. The quantity of water used for irrigation was measured with a flume meter and then percentage of water saving was calculated. The study revealed that furrow irrigation system significantly improved the number of fruits per tree (1153), fruit yield (179.89 kg per plant) and juice percentage (48.38%) compared with flood irrigation system where the number of fruits per tree were711, fruit yield was 110.61 kg per plant and juice percentage was 46.31%. However, TSS/acidity ratio, and peel and rag percentage were not affected by the different irrigation systems. In furrow irrigation system 24 irrigations were applied per year with average water saving of 46.14% and water use efficiency (WUE) was 4.58 kg m-3 whereas in flood irrigation system average numbers of irrigations were 15 per year and WUE was 2.34 kg m-3only. Therefore, furrow irrigation system is recommended for the citrus growers to improve the water use efficiency, yield and fruit quality of Kinnow mandarin.

A new application of the internet of things in a low-cost greenhouse with no networked intelligent control equipment.The systematic water-saving management focused over the whole growth stage of crops, and it can effectively increase yield and quality.Replace some chemical fertilizer with fully-decomposed organic fertilizer and new types of fertilizer to reduce negative impact on soil and the environment.Regarding pesticide usage, we advocate prevention first and treatment second.Improve systematic water-saving management with regard decreases in crop yield and quality.Abstract. A basic greenhouse is an inexpensive type of greenhouse, which lacks networked intelligent control equipment; it is currently the most common type of greenhouse used in China. To manage planting activities intelligently and improve water use efficiency in these greenhouses, an intelligent planting management platform for strawberry based on the internet of things (IoT) is developed. On the platform, human-computer interaction occurs through the WeChat app on a mobile phone so that manual control of the strawberry environment in the greenhouse can be conducted. In this study, we add a user module in the perception layer of the IoT to obtain the information and manually control the environment in a basic greenhouse. The network layer uses narrowband IoT wireless transmission technology based on 4G. The application layer is designed with a systematic water-saving management knowledge base for strawberry. The systematic water-saving management feature includes seven parts: strawberry variety selection, planting seedlings, flower and fruit thinning, environmental control, disease and pest prevention and treatment, fertilizer management, and water-saving irrigation. Through the human–computer interaction platform, growers can receive decision-making options, planting management evaluation, query information retrieval, and regular relevant planting information. The application results of the platform showed the following: compared with management experience of growers, the water use efficiency of yield (WUEy) increased by 128.55%, the water use efficiency of production value (WUEpy) increased by 226.31%; the amount of chemical fertilizer decreased by 40%, the amount of pesticide decreased by 61.67%, and the cost of pesticide decreased by 32.48%; thus a decrease in the use of both fertilizer and pesticide was achieved. This study can directly provide technical support for strawberry intelligent management in basic greenhouses, and can also be used as a basic platform intelligent management systems for other crops grown in basic greenhouses.

The Impact

An experiment was carried out to study the impact of drip fertigation in tomato crop at RCA, MPUAT, Udaipur during rabi season 2015-16 in split plot designed with three irrigation schedules [100 (I1), 75 (I2) and 50% PE (I3) through drip] and five fertilization schedules [100% RDF (F1), 75% RDF (F2), 75% RDF + 2 foliar spray of 1% urea phosphate (F3), 50% RDF (F4), 50% RDF + 2 foliar spray of 1% urea phosphate (F5)]. Higher number of nodes per plant (21.20 and 19.89) and yield (169.03 and 186.38 q/ha) were registered with treatments receiving drip irrigation at 75% PE and 75% RDF through fertigation + 2 foliar spray of 1% urea phosphate, respectively. Quality characteristics were enhanced with combined use of I2F3 treatment. The highest water use efficiency i.e. 26.37 ka/ha-cm was recorded under I3F3 treatment and fertilizer use efficiency with I2F5 treatment combination (165.78, 254.31 and 381.46 kg/kg NPK, respectively).

Use Efficiency

Water is the prime natural resource, which is often costly and limiting input particularly in arid and semi arid regions, hence needs judicious use to reap the maximum benefit from this limiting resource. Indian farmers are now finding ways to shift from traditional practices to more modern technologies for crop production. Of late, drip irrigation is receiving better appreciation, acceptance, and adaption and plays an important role in saving the water in water scarce areas. It enables the efficient use of limited water with higher water use efficiency. Adaptation of drip irrigation in rabi maize which is one of the amenable crop for drip irrigation system is gaining momentum because of its higher productivity coupled with higher price. Irrigation application can be reduced by 50 to 80 per cent with drip irrigation compared to surface irrigation. Further, drip irrigation has the potential for improving two of the most common contributing factors to N leaching – over fertilization and over irrigation. Therefore, optimum irrigation levels with suitable method would help in enhancing the economic yield as well as water use efficiency of maize crop.
