Nursery beds are prepared by digging up to a depth of 30cm and the beds are properly cleaned, leveled and the soil is enriched by applying well rotten FYM. To protect the Marigold seeds from the infestation of ants, BHC powder is dusted on the raised beds. Approximately, 3kg of seeds is sufficient to plant the one-hectare area. Marigold seeds are sown thinly and are covered with light soil. The beds are then watered with fine rose water can to avoid the displacement of seeds.

How does a greenhouse help plants grow better?
The mechanism of greenhouse structures can help the plants grow better such as controlling the temperature of the greenhouse, controlled air movement can help the plants with carbon-dioxide, special soil maintenance practices and humidity management. All these factors within the greenhouse contribute to better flowering and fruiting.
What is the purpose of having a greenhouse?
In India, farming is highly dependent on the climatic conditions and this is the biggest challenge to every farmer. Most of the farming in India is based on the traditional ways and this is the reason why India imports many fruits and vegetables from other countries to address the food security problem. Modern techniques like greenhouse farming can improve the production and quality because the system depends less on external environmental conditions and has many more advantages over the traditional farming methods. With a good produce the income of the farmer is also expected to increase thereby making him economically stable.
What is the best greenhouse covering?
The material used for covering the greenhouse effect the performance and productivity of the structure. Covering materials greatly impact the quality and quantity of light entering the greenhouse. The best materials for greenhouse covering are Glass, Plastic sheeting (polymethyl methacrylate, fiber glass and polycarbonate) and Plastic films (polythene, ethyl vinyl acetate, poly vinyl chloride).
What kind of feed is given to farmed fish?
Mash feed is a popular and widely used fish feed in India. The main ingredients of the feed include de-oiled rice bran, groundnut cake and cotton seed cake. Pellet feed, which is commercial variety of feeds available in the market, can also be used. Supplementary feed along with the natural feed must be given to the fish for faster growth. Natural feed can be plankton, basal organic elements, small aquatic insects, grasses, rotten plants and animals, etc. supplementary feed can be crop grains, blood of birds and animals, maize powder, dried molasses, sesame cake etc.
Why fruit falling occurs in litchi?
Due to lack of nitrogen and water in the soil and hot and strong winds, litchi fruits start falling at a young age. Due to proper arrangement of manure and water, there is no problem of fruit drop. Planofix (2 ml / 4.6 l) one week after fruiting. One spray of 20 mg/L solution can prevent fruit drop.
How flowering and fruiting occurs in litchi?
After four to five years, flowers and fruits start coming in the litchi plants prepared by air layering. It has been seen from experiment that by stopping irrigation in plants about three months before the expected time of flowering the scene is very good.
There are three types of flowers in litchi plants. In litchi, the fruit develops only in bisexual female flowers. In these flowers, the stamens are below the ovary so pollination is needed by insects so for more fruiting female flowers should be properly pollinated and insecticides should not be sprayed at the time of pollination, otherwise the fruit is affected.
What can be grown as intercrop in Litchi farming?
It takes about 15-16 years for the litchi tree to mature completely. Therefore, in the initial stage the land between litchi plants can be utilized properly by planting other fruit plants and pulse crops/vegetables. Due to this, along with additional benefits to the farmers, the soil will improve. Fertility also develops. In the form of intercrops, pulses, oilseeds and other crops like Bodi, French Bean, Okra, Moong, Kulthi, Surguja, Mahua, Paddy etc. can be cultivated successfully.
What is Shahi and it belongs to which cultivar?
This is a commercial and early variety of the litchi which is becoming popular day by day. The fruits of this film are round and dark red in color, which ripen by 15-30 May. The fruit has a high amount of aromatic pulp, which is the main feature of this variety. Proper water management at the time of fruit development increases the yield. 80-100 or Upan can be obtained per year from 15–20-year-old plant of this variety.
What is the climatic requirement for litchi farming?
The temperate climate has been found to be very suitable for the production of litchi. It has been seen that due to clear sky increase in temperature and dry climate in the month of January-February there is a good in litchiplant in which more flowers and fruits are produced.
The development of litchi fruits is good in March and April due to less heat as well as normal humidity in the environment in April-May improves the quality and development of pulp in the fruits.
