Operation And Management

Proper management of vegetable drip-irrigation systems requires knowledge of soil hydraulic characteristics, plant-growth and water-use characteristics, and evaporative demand. The resultant schedule must integrate these properties and conform to existing irrigation system and cultural constraints. Irrigation management must be coupled with the fertilizer management program to avoid excessive water applications that leach plant nutrients. Because drip irrigation applies water to discrete locations along the plant row, limited irrigated areas can result, and this is an important consideration for irrigation system design, cultural practices and management, and irrigation system operation and management.

Improving irrigation management in vegetable crop production reduces production costs, saves water, and reduces the risk of nutrient leaching. As water movement in the root zone below mulched beds is difficult to see, injecting soluble dye through the drip irrigation system provides a simple and practical method to visualize water movement in the soil. Understanding water movement in raised beds is essential for improving irrigation scheduling and nutrient delivery. This document is HS980 one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.

In South-Eastern Nigeria, during the dry season from November to April, vegetables are always in short supply and consequently expensive. Hence, there is a need to design, develop an affordable and simple bucket drip irrigation system that can be used to grow vegetables under limited water supply conditions. Using the estimated consumptive use of the proposed crop okra and the area occupied by the crop stands, the capacity of the bucket as a source of water was computed. The bucket filled with water was placed at a head of 1 m. The water was allowed to flow through emitters located at 30 cm intervals along the lateral lines laid at the land slope of 2%. Two lengths of PVC tubes 11 m long, 1 mm thick and internal diameters 16 mm, Micro-tubes 5 cm long and internal diameter 1.2 mm, were used. The discharge from each emitter was determined through volumetric measurements. The system was then evaluated using the Christiansen’s method and the Merriam and Keller’s method and assessed using ASAE standards 1996(a) and 1996(b) performance rating. 22 sampled emitters evaluated from the lateral line showed total energy drop of 2.5 x 10-5 m, flow variation (FV) of 8%, coefficient of variation (CV) of emitter discharge of 0.02, uniformity coefficient (UC) of 97% and emission uniformity (EU) of 73%. The results show that the system is efficient and can be used by farmers to meet the demands for vegetables in the dry season.

This article is intended to provide information to producers and Extension agents that are interested in using drip irrigation for vegetable production. Cabbage production in Florida is dominated by the use of seepage or sub-irrigation. This system has traditionally been used because it is inexpensive to maintain and simple to use. Seepage irrigation works by damming tail water ditches, pumping water into open furrows, and effectively raising the water table to a depth accessible to the crop root system (For more information see EDIS Publication #HS1217). This type of irrigation practice is almost completely unique to Florida and is possible due to the persistence of a shallow, impermeable layer in the soil profile. This system can require vast quantities of water to be pumped from the aquifer in low-rainfall years. Plasticulture, or the use of drip irrigation and plastic mulch, has been proposed as an alternative production method for cabbage production in Florida. An on-farm demonstration was set up to provide a platform for collaboration between researchers, growers, and Extension professionals. The demonstration was located on Greene’s Farms in Bunnell, FL. The goal of the demonstration was to grow high-density cabbage populations using plasticulture side by side with seepage on a commercial farm. Fertilizer and irrigation management was closely matched between systems. The plasticulture system was designed to provide a small-scale installation of this technology for learning and commercial adaptation purposes. This small-scale system has great potential for encouraging adoption of this type of system with low risk to the grower. This article illustrates an innovative approach for converting from seepage irrigation to plasticulture and points out some options and challenges for growers considering a plasticulture system.

Rainout Shelter

Uneven and low precipitation areas of Nepal are continuously suffering from drought and received low productivity because of unavailability of suitable drought tolerant maize genotype. An attempt has been made first time in Nepal by constructing an automated rainout shelter with soil moisture based automated drip irrigation system at National Maize Research Program in 2018-2019 to conduct an experiment on drought tolerant maize genotype. The rainout shelters automatically covers the cropping area as soon as the rain sensor received a single drop of precipitation and also if the light intensity decreased to value set in the control panel. Likewise, the soil water level in different treatments were maintained on the basis of the treatment controlled with automatic drip irrigation system set to irrigate at threshold value set in the microcontroller. The complete system had found very useful in determining accurate amount of water required to cultivate drought tolerant maize genotype. We have tested drought tolerant variety RampurSo3Fo8 under 10 level of irrigation and it was determined that 495.2 mm of water is maximum level of water to produce highest yield of 3.32 t/ha whereas 445.6 mm to 247.6 mm of water could can be manage to produce competitive yield without any reduction. An experiment under such kind of infrastructure provide useful information on irrigation management practices required for drought variety in the natural environment. The research output also guides farmers and agriculturist in making Nepalese agricultural more sustainable, mechanized and productive.

Reducing emitters’ working hydraulic pressure appropriately can cut down construction cost and running cost of the whole drip irrigation system. Reduction of the emitters’ working hydraulic pressure, however, will directly affect emitters’ hydraulic characteristics and anti-clogging property. In this study, experimental research into the hydraulic characteristics of multiple types of emitters under micro-pressure and compared the hydraulic characteristics with the ones under normal hydraulic pressure has been done. The experimental results showed that compensating emitters had poor water discharge uniformity at critical startup hydraulic pressure while non-compensating emitters, dripping arrows and dripping tape had consistent water discharge uniformity under micro-pressure and under normal pressure.

Drip irrigation provides an efficient method of fertilizer delivery virtually free of cultural constraints that characterize other production systems. Achieving maximum fertigation efficiency requires knowledge of crop nutrient requirements, soil nutrient supply, fertilizer injection technology, irrigation scheduling, and crop and soil monitoring techniques. If properly managed, fertigation through drip irrigation lines can reduce overall fertilizer application rates and minimize adverse environmental impact of vegetable production.

Irrigation has been pointed out in recent decades as the major consumer of water. Considering the need for a rational use of water resources and the importance of mulching for planting, this study evaluated the effect of organic mulching (sugarcane straw) under soil water storage for cabbage crop development. This research was conducted at CCA/UFSCar, and the experimental design was a completely randomized design with four replications and two treatments with and without sugarcane straw. Water application was performed by a drip irrigation system and irrigation management was determined from data collected by TDR. The use of organic mulching did not interfere with cabbage productivity under greenhouse conditions. The straw presents efficiency for reduction of soil evaporation and, consequently, increases water-use efficiency. The soil cover made it possible to save up to 28.1 mm (14.5%) of the water depth.
