IntroductionCultivation of vegetables and flowers under protected (greenhouse)conditions has emerged as a major alternative to growers in recent years.
The greenhouse method ensures a constant, year-round supply of highquality produce for the modern farmer whilst overcoming many of theobstacles imposed by adverse climatic conditions and water and landshortage.Greenhouse cultivation allows farmers to control most of the productionparameters, optimizing land use and yield distribution during the growingseason. The many advantages of greenhouse cultivation offers, constitutean incentive for farmers all over the world to invest in greenhouse projects.Irrigation and fertilization are the most important production factors inmodern greenhouses, where production is based on soilless medium, aswell as in natural soil.Growing on soilless culture (substrates) provides the advantage ofcontinuous control over water and nutrient quantities applied and theability to flush growing media within the water cycle.NaanDan Jain Irrigation possess decades of experience in developmentand manufacturing of a wide range of irrigation technologies for all typesof crops under diverse growing methods.The accelerated development in greenhouse technologies has led thecompany to develop a special product line for greenhouse irrigation,climate-control (including humidity and temperature regulation), and forthe application of chemicals by spraying.
The material in this manual is based on the experience and technologicalknowledge that has been accumulated by NaanDan over the years. Thematerial here in can be used in the design and establishment of irrigation,climate control and other systems in greenhouses, nurseries and net-houses.
This manual is intended for dealers, designers and irrigation consultantsand covers a wide range of applications and technologies forgreenhouses and nurseries, focusing on user-friendly applications.
NaanDan Jain offers an extensive range of irrigation technologies, onlypart of which is presented here. Please contact your local representativeor NaanDan Jain's technical department for further information.

There are four alternative irrigation modes for greenhouses,each targets a specific application
- Irrigation for bench cultivation- Total coverage irrigation in multi-span greenhouses.- Plant propagation systems- Irrigation in plastic tunnels.

Bench irrigationModular micro-sprinklers and sprayers
Determine the width of the area that you want to irrigate. In most cases the width will determine the sprinkler typeDecide if you want to apply water at a high or low application rate.Determine the height at which you want to hang the sprinkler, whilst ascertaining the desired precipitation of water tofall on the bench and the width of the band to be irrigated.The above three choices will determine the appropriate nozzle and anti-mist color.In some cases, a particular factor, such as the percentage of water in the bench, may determine the other variables suchas application rate and sprinkler height.

Choosing your sprinkler:
The selection chart is designed to quantify the functions of bench width, flow-rate, installationheight, effective watering percentage, and the coefficient uniformity (CU) percentage.Calculations in the chart are based on 1.0 m sprinkler spacing along the pipe.The sprinkler selection chart represents an attempt to simplify a complicateddecision making process while at the same time presenting alternatives.The 1.0 m sprinkler spacing, on which the chart is based, has been found to achieve optimumresults by balancing cost, CU, and the optimal percentage of water falling within the designarea.In our calculations, precedence has been given to the CU.Recent advances in specialized greenhouse irrigation products andcomputer modeling have contributed to creating an optimized sprinklerlayout specifically designed for greenhouse application.By creating a highly uniform irrigated strip, benches and bays can now beirrigated in a single line while controlling the proportion of water falling onto the bench,to a highly uniform distribution rate.Precipitation rates can be preset either high or low, dependant on the specific requirementsof the grower.
The side by side layout using theanti-mist device achieved maximaluniformity at specific wetted strip.

In general, irrigation of soilless culture requires frequent irrigation of theshallow substrate (between 10-20 cm).There are two conventional methods of cultivation in soilless culture:
BeddingDrip system for growing vegetables and flowers on beds:Product selection and design criteria for drip system• Dripper discharge: 1.0, 1.6, 2.0 l/hr (PC or regular)• Dripper spacing: 15 - 30 cm (according to plant spacing or when a
continuous wetted strip is required)• Lateral diameter: Either 16 or 17 mm• Number of laterals: 1 per row or 1 per 2 rows for dense cultivation of
flowers and herbs• As the number of laterals increase and the dripper spacing decreases,
a lower discharge dripper is selected to maintain low precipitation rate.
Drip system applications
A. Soilless culture
Wide bedEither 4 or 6 rows2 or 3 drip lateralsExample: herbs, lettuce, carnation
Narrow bed
2 rows2 drip lateralsExample: roses, tomatoes etc.
Principal methods1. Button dripper with singles outlet (or 2 outlets for sleeves)2. Dripper spacing: one dripper per plant3. CNL is recommended for system that operate more than 4 times a day4. Integrated dripper line (Naan PC or NaanTIF) can be used to irrigate large pots or bags in commercial nursery applications.

B. Drip system on soil
Dripper selection & spacingThe flow chart should be regarded as a general guide.Other considerations should be taken into accountsuch as water requirement, and source capacity.
Final consideration:Ascertain the precipitation rate of the selected drip system.For values exceeding 10 mm/hr a minimum irrigation dose of 2.0 mm should be taken into account. (20 m3/ha)

With intense drip irrigation system (closely spaced laterals and drippers) try to selectlow dripper flow at low pressure, to minimize the precipitation rate.
A drainage slope of 1-2% is normal in a greenhouse.The drip lateral should be positioned to run from the high point to the low point*.The sub-main should be placed at the highest point accordingly.(*In direct contradiction to what has became regarded as the traditional method of positioningthe sub-main lines in greenhouses)
Design considerations and practical advice1.
2.
Sub mains and ends of lateral dripper lines should be situated to be easily accessible for flushing3.

Climate Control of Temperature and Humidity in Greenhouses
What is the importance of the droplet size created by the NaanDanFogger?With a nozzle distributing 7 l/hr at a pressure level of 4 bars, the averagefog droplet size is 90 microns. These droplets evaporate with minimalwetting of the plant leaves or greenhouse floor.
FoggerClimate control in a greenhouse is based on the principle of the exchangeof energy between the air and the fog moisture supplied by the NaanDanFogger.One calorie is the amount of heat necessary to raise the temperature of1 cm3 of water by 1˚C.The conversion of water from liquid to vapor absorbs heat from thesurrounding air, at a rate of 590 calories/1 gram of evaporated water(1 cm3). This process lowers the air temperature.Efficient installation and operation can reduce the temperature in thegreenhouse by between 4 to 6˚C, depending on the environmentalconditions. Efficiency of the cooling system depends on two environmentalfactors:- External temperature- External humidityEssential conditions for efficient cooling with the NaanDan Fogger are:- An efficient ventilation system which continuously introduces externaldry air into the greenhouse to replace the humid air.- Pulse operation of the fogging system, to minimize foliage wetting.

The pulse duration should be as short as possible, between 1 to 3 sec. (Under certain conditions, longer durations can beconsidered).The interval between fogging pulses should be based on the factors of humidity, temperature levels, greenhouse ventilationand height of the foggers.

Cooling and humidifying cannot be conducted simultaneously.
HumidificationIn the event that the humidity level needs to be increased then the ventilation system must be shut down. The durationof the fogging process should be as short as possible (1.0 second).The intervals between fogging pulses will vary according to the minimal relative humidity required.During the morning, when temperatures rise and humidity decreases, the humidity sensor will cause the fogging systemto operate.

Fogger SystemThe Fogger climate-control and pest-control system has been developedand tested to be operated either independently or in tandem.This method is cost effective by its savings in labor and by minimizingthe amount of pesticides required.GeneralThe Fogger system as a method for pest control is suitable for a varietyof crops and conditions as a subsititute for conventional spraying systems.In densely planted crops, introduction of circulation fans into thegreenhouses may be beneficial.The pest-control system must be isolated from the water supply system.Separate tanks and pumps that are not connected directly to the watersupply source are be used in the pest control system.After spraying, pipes must be emptied of all chemical residues.Spraying solution concentration must be prepared strictly according tothe manufacturers' recommendations. A wide range of products can beused, including powders.It is recommended to spray in the late afternoon or evening.
The Fogger system has been found to particularly efficient in thepreventative treatment of diseases and pests.
The methodThere are two principal spraying methods, both of which are based onthe T Fogger configuration or the new Super Fogger installed at theperpendicularly to the direction of the rows.Water discharge is 14.0 l/hr andspacing is 1.5 x 3.0 m. (1.5 m onthe line, 3.0 between the lines)Installation heightIn the dual-purpose system - climatecontrol and pest control - theFoggers should be installed as highas possible (minimum 3.0 m aboveground).For targeted spraying systems, theFoggers should be installed 2.0 mabove low crops (such as roses),and 1.0 m above the highesttrellising cable in trellised crops (suchas tomatoes and cucumbers).

Method A: Spraying small and medium plotsIn small and medium plots (0.1-1.0 ha), an air compressor is used tointroduce the pesticides into the pipes, and air pressure is used to emptythe pipes after spraying.N.BThe pipes volume should be as small as possible, and should not be largerthan the volume of the planned spraying dosage. Accordingly, the plotsize will be 500 - 1,000 m2.Fogger laterals are16 mm class 6,. The manifolds and mainlines areclass 6 with the smallest possible diameter.The spraying control head is as close as possible to the operation valves.The valves are electric plastic either 3/4" or 1".The air discharge capacity of the T Fogger is 220 l/hr. About 1,500 litersof air are required to empty the pipes in an area of 1,000 m2.Work stages- Prepare the spraying solution according to recommendations- Fill the air tank to the planned pressure (the valve to the greenhouseshould be closed)- Open the valve of the spraying tank. The pesticide solution is forcedinto the Foggers.- End spraying when all the solution has been used or when pressuredrops to 2 bar - closing pressure for LPD (about 2 - 3 minutes for1,000 m2).- Continue applying air pressure for one more minute or until all pesticideresidues have been flushed out of the pipes. If the air volume is insufficient,it may be necessary to refill the tank.It is recommended to allow the compressor to cool down for a fewminutes between operations.

Method B: Spraying large areasIn large greenhouses, where a large number ofoperations may be required, a pump should be usedPrinciplesThe spraying solution is injected into the pipes bya booster pump, block by block. The system isflushed with clean water after spraying. The controlhead for this system is less expensive and operationis simpler. Conversely, the pump requires to becalibrated and a larger amount of spraying materialis used.Head control structureThe booster pump that injects the pesticides intothe Foggers is connected to two tanks:- Spray tank with height level gauge- Clean water tankTwo manual valves, for shutdown and connection, connect the tank tothe booster pump. A small compressor is connected to the junction, witha non-return valve to flush the residual solution and to empty. the pipesThe spray valves are controlled by 24 VAC switches for manual openingand closing.

Water tank for cooling
Work stages- Prepare the total quantity of pesticide required for spraying the whole area. When calculating the required volume, includethe volume of the pipe leading to the Foggers, adding about 50%.Example:Pesticide quantity for 2.0 ha: 2,000 litersVolume of 50 mm main line: 600 litersTotal tank volume required: 2,600 liters plus an additional 5% (according to height/location of the outlet in the tank)Spray the pesticide by operating the pump. Divide the pesticide dosage for each block into two equal doses. Wait at least15 minutes between each application to allow the solution to dry and to prevent runoff. It is possible to continue sprayingthe other blocks before applying the second half of the dosage.Sometime the spraying can be in one application. However it’s important to ensure that there’s no run off.
Calculation of spraying duration per dosageIt is recommended to calibrate the system to validate the calculation.

- After spraying, flush the system with as little fresh water as possible. Close the spraying valve and open the valve of thefresh water tank.It is very important to adhere to the flushing order.Flush from the first valve that is closest to the control head, and complete the cycle with the valve situated furthest fromthe control head.- Drain the system until it is completely free of water to prepare for the next spraying session. It is recommended to use asmall compressor.
Caution: Air currents can easily carry the tiny droplets (50-100 microns) through any tear or hole in the greenhouse covering.These droplets may pollute the outside environment, causing possible harm to people, animals, and even to other plants.Therefore, to prevent pesticide clouds from escaping to the outside atmosphere, it is essential to ensure that the greenhouseis completely sealed while operating the Fogger system. It is recommended to fog in the late afternoon or evening.
