Ben Phillips advocates the pursuit of a number of techniques to successfully pollinate greenhouse vegetables. Which fruiting vegetable crops work well in the greenhouse? According to Phillips, cucumbers, watermelon, melon, summer squash, tomatoes, peppers, eggplant and beans are great greenhouse candidates for early summer production. Peas can be started early in these structures as well.
For larger fruited vine crops, trellising can be utilized with mechanisms to support the weight of fruits onion bags, panty hose, etc. Bush type and vine type squash plants can be utilized with extra attention paid to spacing.
Which greenhouse crops require pollination assistance? Standard cucurbits have separate male and female flowers, which require a pollinator to bring pollen from a male flower over to a female flower. Cucurbits naturally produce many more male flowers than female flowers to ensure that bees come in contact with pollen while searching for the larger nectar pots in female flowers. Phillips said breeding has created different flowering behaviors of these crops. Gynoecious cucumbers have been bred to produce predominately female flowers to maximize yield.
Some seed companies will sell these seeds pre-mixed. Seedless watermelons require 30 percent interplanting with diploid pollenizers to maximize fruit set and yield. Often, a standard seeded watermelon is used as a pollenizer. Some muskmelons and cantaloupe cultivars can have self-fertile hermaphroditic flowers with both male and female parts, but still require a pollinator.
However, the tubular, downward-facing flowers need to be agitated to release pollen from the male part onto the female part. Though this occurs naturally by wind, pollination can be enhanced with mechanical vibration provided by growers or bees.
In addition, relative humidity should be between percent to prevent pollen from being too dry to stick to the female part or too sticky to fall away from the male parts, Phillips said.
Some parthenocarpic varieties exist that set fruit in cooler temperatures without pollen transfer. Due to the complicated flowers of legumes, bees must learn to pollinate them. There are four primary managed pollinators used in agriculture, with different propensities for use in enclosed structures. All bees can see ultraviolet light, and use it for orienting to their surroundings. Among the types of structures to grow in, those covered in a material that allow the transmission of UV light are the most preferable, such as glass, polymethacrylate PMMA , and polyethylene PE.
You need to be ahead of them all the time. By outsourcing the beekeeping to someone else, they may need to consider how much access to grant to an individual or team of beekeepers to the greenhouse s. The traditional hives are heavy and hard to move, and so smaller nucleus and micro- nucleus colonies are used. But, these need to be managed carefully to avoid swarming, absconding and overheating, he said. In addition, they are the most aggressive managed pollinator, and would not suit an operation where people need to work close by.
Commercial bumblebees Bombus spp have been an emerging market for pollination inside structures in Europe and North America, Phillips said. Bumblebees live in much smaller colonies, making them easier to transport. Phillips said companies, such as Koppert Biological Systems, and Biobest, have devised ways to rear them continually through the winter in artificial environments for seasonal production needs across the continent, and have designed special packaging enabling them to be shipped through the mail with a food source.
Growers can determine the visitation level of bumblebees on tomatoes and peppers by the bruising that occurs on the anther cone of the flower: the darker the bruise, the longer the visit and more effective pollination, Phillips said. Bumblebees have also been shown to successfully pollinate muskmelons in New Zealand greenhouses, and are one of the most prominent wild pollinators of field-grown squashes.
Current recommendations are four to six colonies per acre of enclosed space. For a 30 x 48 feet up to a 30 x feet greenhouse, one bumblebee colony would be more than adequate for a tomato, pepper, or vine crop, Phillips said Solitary cavity nesting bees are supported by a smaller industry than honeybees and bumblebees.
Mason bee Osmia spp life cycles are limited to flight in April-June, and they are used for early blooming tree fruit. They have been successfully used in pollination of brassica crops for seed production in cages and high-tunnel strawberries. One species was found to be successful as indoor pollinators of peppers in Denmark, but could not maintain adequate nutrition to provide continued pollination of later flowers.
In cucumbers, they were found to prefer the uppermost flowers in the brightest area of the structure, and they needed alternative softer-leaved plants to construct their nests.

11 Unique Types of Asian Vegetables and Produce to Try
Asian vegetables and produce belong in every home cook's repertoire. Asian cuisine refers to the foods from a region that is home to more than half the world's population. Because of the term's vast geographic mass, some ingredients are used across many regions, while others are specific to one or a few regions. For instance, lemongrass, predominant in Southeast Asian cooking, isn't used in East Asian cuisines, but ginger is used throughout the continent.
Vegetable oils are triglycerides extracted from plants. Some of these oils have been part of human culture for millennia. Many oils, edible and otherwise, are burned as fuel, such as in oil lamps and as a substitute for petroleum -based fuels. Some of the many other uses include wood finishing , oil painting , and skin care. The term "vegetable oil" can be narrowly defined as referring only to substances that are liquid at room temperature,  or broadly defined without regard to a substance's state liquid or solid at a given temperature. Vegetable oils can be classified in several ways. For instance, by their use or by the method used to extract them. In this article, vegetable oils are grouped in common classes of use. There are several types of plant oils , distinguished by the method used to extract the oil from the plant. The relevant part of the plant may be placed under pressure to extract the oil , giving an expressed or pressed oil. The oils included in this list are of this type.
Section 2 Description and characteristics of the main food crops
Rice is the staple food for Asian people; it is prepared by cooking or ground as flour for bread making, thus helping to feed the rest of the world population. Various kinds of rice are produced to suit the taste of the consumers. Rice cultivation is done either in marshy, lowland areas with plenty of water or in plateau or hilly regions where natural rainfall provides adequate amounts of water. Rice can be cultivated either by hand or by partial or full mechanization, according to the technological development of the country and the need for productivity. Whatever kind of operation is done, the following step-by-step processes are necessary.
