Research Greenhouse -Wheat

Saveer’s WGR Greenhouse provides different conditions inside the greenhouse for the researcher to generate information on pathogenic variability, maintenance, role of abiotic factors in disease development, host resistance, use of toxins in screening of breeding lines, Identification of durable resistant genotypes and varieties against leaf blight complex, effective management of quantitative and qualitative losses caused by disease etc.

The Wheat Greenhouse can also be constructed on roof top of buildings/Labs in places of land scarcity or the fields being too far off. With the technology available now Saveer has made it possible to haveroof top greenhouses which are more environmentally friendly and very easy for the researcher to access the facility from his laboratory for efficient monitoring of the research projects.

This greenhouse can beaccessedfromany place with internet facilities to monitor different parameters and even a researcher can change them without actually visiting the greenhouse.

  • Fastening the life cycle
  • Time scale isolation

The important parameters in WGR Greenhouse are:



Suitable Climate

Wheat is crop of cool environment. However, it requires different temperatures at different stages of plant growth and development. The different temperature gradient can be created inside theWGR Greenhouse as per the stage of the crop.


Wheat grows best in temperatures between 21 and 23 °C. The minimum temperature that wheat can withstand during its growth cycle is about 4.4 °C. Wheat does not grow well if temperature exceeds 35 °C. Temperature below 4.4 °C during seed germination will result in lower germination rate. Temperature higher than 35 °C during maturation will result in lower yields. The required temperature can be created as per the crop and researcher requirement.


Wheat grows best in areas with lower humidity. Wheat growing in low humidity areas will have fewer problems with humidityrelated issues like fungus. In areas of high humidity that produce wheat, the wheat must be dried quickly after harvest to keep it from spoiling. The WGR greenhouse is equipped with the system that can provide desired humidity range.


Wheat requires a lot of sun. It grows best in full sun, but some parts of a field can grow well if partially shaded. Wheat is a grass that uses sun to create growth energy. More sun, as long as the plants' water and temperature requirements are met, generally results in better crop yields. The same requirement can be fulfilled by VWS-18 technology through which the different DLI i.e. differential light integrals can be achieved for the experimental requirements.


The amount of rainfall required for wheat cultivation varies between 30 cm and 100 cm. The major wheat lands of the temperate regions have an annual rainfall of 38 cm to 80 cm. The RRB greenhouse is equipped with AR technology that can give the required amount of water in the form of rain droplets as per the researcher requirement.

Wind velocity

With the wind speed,the movement of adult insects is driven by the airflow. It affects the release and spread of fungal spores and produce wounds which create conditions for fungal infection. The WGR greenhouse will be designed as per the researcher requirement to study the effect of wind’s velocity on the crop and other dependent parameters.


Winter wheat in its early stages of development exhibits a strong resistance to frost, down to - 20°C. The resistance is lost in the active growth period in spring and during head development and flowering period. Frost lead to head sterility. Because of this sometimes more damage is done to the winter crop by spring frost than by winter frost.Wheat is most susceptible to frost damage at flowering. The researcher can study all the parameters as per the requirement in WGR greenhouse in which the independent chambers for frost are available for the study.

Water quality: pH and E.C

The crop is moderately tolerant to soil salinity but the EC should not exceed 4 mmhos/cm in the upper soil layer during germination. Yield decrease due to salinity is 0% at EC 6.0, 10% at 7.4, 25% at 9. 5, 50% at 13 and 100% at EC 20 mmhos/cm. The desired pH and EC can be provided automatically by feeding the data in the attached computerized system.

Water management

For high yields water requirements (ETm) are 450 to 650 mm depending on climate and length of growing period. The crop coefficient (kc) relating maximum evapotranspiration (ETm) to reference evapotranspiration (ETo) is: during the initial stage 0.3-0.4 (15 to 20 days), the development stage 0.7-0.8 (25 to 30 days), the mid-season stage 1.05-1.2 (50 to 65 days), the late-season stage 0.65-0.7 (30 to 40 days) and at harvest 0.2-0.25. The same can be provided as per the crop stage requirement automatically just be feeding the data in the attached computerized system.

Water stagnation/ Submergence

Ponding on the soil surface for more than a day is known to be harmful to wheat watered by flood-irrigation. Water uptake and extraction patterns are related to root density. In general 50 to 60 % of the total water uptake occurs from the first 0.3 m, 20 to 25 % from the second 0.3 m, 10 to 15 % from the third 0.3 m and less than 10 % from the fourth 0.3 m soil depth. Different plots can be planned in the WGRgreenhouse to study the water stagnation/ submergence related studies as per the researched requirement.

Time of sowing

Sowing of wheat takes place in October to December. As favourable environment is created in WGRgreenhouse as such researcher can grow the crop round the year to continue its research work.

IPM Studies

The researchers are giving more emphasis on the development of crop varieties that have good resistance to important pests and biological and ecological pest control methods. The researcher can study all the required parameters in the WGR greenhouse as per its requirement.

Harvesting and Drying - Advice

Consider harvesting at 18% to 20% moisture and artificially drying the grain.
Air drying

  • Air drying wheat in storage will result in higher test weight and quality.
  • When bin-drying wheat, the bin should only be filled to a depth of about 7 to 9 feet (any deeper and air flow will not be adequate).
  • Make sure the initial layer is dry before filling the remaining space.
  • Wheat provides more resistance to air flow than corn, making it a tough crop to dry in a bin situation.

Continuous-flow dryers

  • Continuous-flow dryers handle wet wheat very well, as they are drying only the portion in the dryer.

Drying temperatures and optimum grain moisture

  • For commercial mill quality, dry wheat at temperatures of 60 degree C or less.

Different models of WGRGreenhouses research are available and can be designed as per the requirement of the researcher. The researcher can work on the constraints of growing wheat and other important factors as per its need and can give the best solution to overcome the problems.
