Materials Used

This research examines solution to overcome the problems of opposition to growing vegetables under protected cultivation, This particular example was chosen to illustrate several important aspects of greenhouse production and marketing that affect profitability such as high prices of vegetable seeds, high prices of materials used in the sterilisation (methyl bromide gas), high prices of plastics in addition to low quality and short duration of use, etc.The study depended on Bossali protected agriculture unit as example of application to measure the performance and efficiency of production and revenue during the period 1994-2006. Using the traditional system of protected cultivation, compared with a new system of performance and management of production processes, depends on the cultivation of some fruit crops under protected cultivation during the period 2007-2015.The study analysed the structure cost of production per greenhouse also discussed some economic indicators such as: farm gate prices, total revenue, total costs and net return of cucumber and sweet pepper (as example for vegetables) and navel orange and keitt mango (as example for fruits). This enterprise budget illustration indicates a lack of profitability of this greenhouse vegetable enterprise using these particular assumptions regarding cost, price, and total revenue. Results revealed that net return reached 1234, 3466 Egyptian pound (LE)/greenhouse (540 m2) in navel orange and keitt mango respectively during the study period.

Tomato comes as the most commonly produced, consumed and subject for trading in the world. Alongside fresh consumption, on the other hand it forms the most significant raw material source of food industry, especially for tomato paste, frozen and dried vegetable-fruit and canned food industry. Turkey's greenhouse vegetable production field for 2016 year is 675173 decars and Antalya forms 51% of this field. Tomato forms 61.72% of Antalya's greenhouse production. The main material of the research consists of interviews made with producers resided in 5 villages/towns, where greenhouse tomato production is carried out densely in Antalya city, Alanya district. In 48 villages and towns, greenhouse tomato production is carried out, according to the official records. In the chosen areas, 365 producers exist. 20% of these producers (73) form the sample size. In the research, it was determined that the producers' average agricultural land possession is 9.13 decars and in 40.53% of these areas they grew tomatoes. None of these producers are engaged in contractual growing. All of the yield is produced for the edible (as table-top item). After the harvest, all of the products are sold in the wholesales market in county and city. 7.89% of the producers have no information on soilless agriculture, as 10.52% of them think that it has no advantages and 73.36% of them recommend traditional agriculture.

With a surface area of 37 000 ha and an annual yield of 3 × 106 t, the south-east of Spain, predominantly the coast of Almeria, is the largest horticultural growing area under protected cultivation in Europe. A survey on perception of the impact of root-knot nematodes on vegetable production was carried out in this area by face-to-face interviews with 120 farm advisors. The survey was designed to evaluate opinions about prevalence and severity of root-knot nematode-induced diseases, percentage of infested area and effectiveness of root-knot nematode control methods. According to the answers, 17.7% of the fields were infested with root-knot nematode and 18.8% of the cultivable area within each site showed root-knot nematode disease symptoms, which came to 2.0% of the total area used to grow vegetables in the region. Average yield loss was estimated at about 30.8% of total vegetable production, and 38.1% of the farm advisors considered that root-knot nematode infections had increased over the last 5 years. Most farm advisors (78.3%) stated that the most commonly used control method was chemical soil fumigation. Non-fumigant nematicides were cited by 59.8% of them, grafting and resistant cultivars by 42.3%, soil solarisation 38.1%, plant extracts 14.4% and biofumigation 6.2%. The majority of farm advisors considered the application of fumigant nematicides combined with soil solarisation, and grafting onto resistant rootstocks as the most effective methods of root-knot nematode control. In addition to the interviews, plant and soil samples were taken from plastic greenhouses throughout the region to determine species of root-knot nematode present. Meloidogyne javanica was the most prevalent species followed by M. incognita and M. arenaria, but species distribution was linked to the predominating crop sequence in each area, since M. javanica occurred less frequently when sweet pepper rather than tomato appeared in the crop sequence.

Combined Data

Excessive N application occurs in greenhouse vegetable production. Monitoring methods of immediately available soil N are required. [NO3−] in soil solution, sampled with ceramic cup samplers, and [NO3−] in the 1:2 soil to water (v/v) extract were evaluated. Five increasing [N], from very N deficient (N1) to very N excessive (N5) were applied throughout three fertigated pepper crops by combined fertigation/drip irrigation. The crops were grown in soil in a greenhouse. Soil solution [NO3−] was measured every 1–2 weeks, and extract [NO3−] every 4 weeks. Generally, for treatments N1 and N2, both soil solution and extract [NO3−] were continually close to zero, and increased with applied [N] for treatments N3–5. The relationships of both methods to the nitrogen nutrition index (NNI), an indicator of crop N status, were assessed. Segmented linear analysis gave R2 values of 0.68–0.70 for combined data from entire crops, for both methods. NNI was strongly related to increasing [NO3−] up to 3.1 and 0.9 mmol L−1 in soil solution and extracts, respectively. Thereafter, NNI was constant at 1.04–1.05, with increasing [NO3−]. Suggested sufficiency ranges were derived. Soil solution [NO3−] is effective to monitor immediately available soil N for sweet pepper crops in SE Spain. The extract method is promising.

The production of greenhouse-grown sweet pepper (Capsicum annuum L.) is irregular with a peak-and-valley pattern of weekly yields. We monitored the yields and environment in a commercial greenhouse in British Columbia over six (2000–2005) growing seasons. Light was defined as cumulative light over the current week, with L_1, L_2, L_3, L_4, L _ 5 and L_6 representing light over previous weeks. Temperature (AvgT) was defined as the current weekly average of 24-h air temperatures, with T_1, T_2 and T_3 representing temperatures over previous weeks. Inputs were also created for the current weekly yield (Y) and previous weekly yields (Y_1, Y_2, Y_3 and Y_4). Neural network (NN) modelling with up to 21 inputs was used to predict yields 1 wk (Y + 1) and 2 wk (Y + 2) in advance of the actual fruit harvest. Data for five different years were combined for model training with the year to be predicted held separate as a validation set. The best models used 13 inputs to predict Y + 1 with an average R2 of 0.66 over the 6 yr. Y_4, Y-Y_1, Y_1, L_1, Y, Y_3, Y-Y_3 and wk (of the year) were important inputs. The environmental inputs were of lesser importance, which suggests that the cyclic nature of pepper yields is inherent in the pepper biology. Predicting Y + 2 was more difficult with an average R2 of 0.59 over the 6 yr. NN have good potential for predicting pepper yields.

Quality Production

India is facing various challenges in fruit cultivation viz., climate change, increasing pressure on natural resources, decreasing land tenure with the ever-increasing population. Besides this, the demand for quality fruit is also on the rise as people are now more aware of a nutritious and healthy diet. The quality with higher production is difficult with the traditional system of cultivation and requires a more scientific approach in cultivation. Greenhouse cultivation technology can enhance quality and quantity both. This technology is required to convert some portion of the present 6.5 million ha of the fruit-growing area to increase national productivity and product quality. The purpose of greenhouse cultivation is to grow crops by altering the micro-environment surrounding the crop so that the plant performs maximum to its genetic potential. It also increases the yield, improves the quality and stability of production and makes commodities available when there is no outdoor production. China is the world leader in greenhouse fruit production with the largest area under this technology. In India, greenhouse fruit cultivation is in its infancy as the only strawberry is commercially being grown under greenhouses. However, in fluctuating environmental conditions and losses in fruit crops due to various biotic and abiotic stresses, protecting the fruit crops for the off-season, quality and higher production will be a necessity in future. Keeping in view the low productivity of fruit crops in India and future needs of round the year quality production, an overview of work and cultivation scenario on this aspect is discussed in this paper.

Abstract While there is a wide range of potentially profitable crops which can be grown in hydroponics under protected cultivation, greenhouse production is dominated by fruiting crops such as tomatoes, cucumber, capsicum and strawberries, and vegetative species such as lettuce, salad and leafy greens, herbs and specialty crops like microgreens. This chapter summarizes information on a selected range of common hydroponic crops to give basic procedures for each and an outline of the systems of production. These crops include tomato, capsicum or sweet bell pepper, cucumber, lettuce and other salad greens, strawberry and rose. Information is given on their hydroponic production systems and environment, propagation, plant density, pruning, pollination, fruit growth, crop nutrition, pests, diseases, disorders, harvesting and postharvest handling.
