Protected Cultivation of vegetable crops in sub-Saharan Africa: limits and prospects for smallholders. A review
Agronomy for Sustainable Development, 2017Co-Authors: Thibault Nordey, Serge Simon, Hugo Despretz, Hubert Bon, Laurent Parrot, Joël Huat, Claudine Basset-mens, Emilie Delétré, Thibaud Martin, Yannick BiardAbstract:Vegetable production in sub-Saharan Africa faces numerous agronomic constraints that will have to be overcome to feed the increasing population and to fight malnutrition. Technology transfer and the adoption of low-tech Protected Cultivation techniques affordable for smallholders are believed to be able to meet this challenge. Protected Cultivation techniques are a set of agricultural practices aimed at artificializing the crop environment through the use of soil covers and/or plant covers to control pests and climatic conditions. Although Protected Cultivation techniques may increase the yield and quality of vegetable crops and extend their production periods worldwide, the transfer of these techniques in sub-Saharan Africa raises questions about their agronomical performances, their profitability but also their environmental impacts. Are low-tech Protected Cultivation techniques adapted to the sustainable production of vegetables by smallholders in sub-Saharan Africa? To answer this question, we present an overview of the agronomic, economic, and environmental performances of low-tech Protected Cultivation techniques in sub-Saharan Africa as reported in the literature. The major conclusions that can be drawn from the review are (1) low-tech Protected Cultivation techniques are not suitable in all climatic conditions in sub-Saharan Africa and need to be combined with other methods to ensure adequate pest control, (2) the profitability of Protected Cultivation techniques relies on the capacity to offset increased production costs by higher yields and higher selling prices to be obtained with off-season and/or higher quality products, (3) breaking with existing cropping systems, the lack of technical support and skills, and the limited access to investment funding are major obstacles to the adoption of Protected Cultivation techniques by smallholders (4) life cycle assessments conducted in northern countries suggested that more efficient use of agricultural inputs would offset the negative impacts of Protected Cultivation techniques if they are properly managed, but further studies are required to be sure these results can be extrapolated to sub-Saharan Africa context.

Protected Cultivation in India: challenges and strategies
2013Co-Authors: Balraj SinghAbstract:Horticultural crop production is highly dependent on environment, and it is very difficult to get favourable climatic conditions for optimum crop growth and development along with protection against major biotic and abiotic stresses as per the crop requirements under open field conditions. The Protected Cultivation, also known as Controlled Environment Agriculture (CEA) or Modified Environment Agriculture (MEA) involves a series of techniques for modification of the natural environment around plants or crops, which totally or partially alter the microclimatic conditions, with the basic aims of improving their productivity, quality and their protection against major biotic and abiotic stresses.

Protected Cultivation of vegetables in global arena: A review
Indian Journal of Agricultural Sciences, 2013Co-Authors: Naved Sabir, Balraj SinghAbstract:Protected Cultivation of high value vegetables and cut-flowers has shown tremendous potential during the last decade or so. With the progress of liberalized economy and the advent of newer technologies in agriculture, Protected Cultivation opens up avenues in agriculture hitherto not seen. These technologies are not only creating avenues at higher level but also to the growers with the smaller landholdings as the higher productivity levels retain economic relevance to agriculture. Protected Cultivation is in a way precise, progressive and parallel agriculture encompassing virtually all facets of agriculture and rather under additional scrutiny of technical relevance to situations and grower and market economics. Since Protected Cultivation is a vast assembly of diverse aspects of agriculture, this review is an effort to bring its current status in global arena covering various components of this important and emerging field of horticulture. Apart from the status, technological components and methodologies, review also discusses principal vegetables like tomato, cucumber, capsicum and lettuce in brief, besides a good amount of treatise on key pests and plant protection strategies in greenhouses.

Protected Cultivation and Nematode Problem
Indian journal of nematology, 2009Co-Authors: Hirendra Kumar Sharma, Pankaj, Balraj SinghAbstract:Protected Cultivation is an emerging technology for raising vegetable and ornamental crops. Due to controlled environmental condition and continuous growing of crops, the root-knot nematode (Meloidogyne spp.) has emerged as a major problem, causing enormous yield loss. The damage progressively increases if proper sanitation control measures are not followed during the polyhouse Cultivation of crops. In the absence of Methyl Bromide other fumigants like metham sodium and Dazomet have been found quite effective when used under plastic mulch for single season, non-fumigants, cadusaphos and oxamyl have also been used alone or in combination to protect 3–4 crops in Protected Cultivation. Combined use of bioagents, neem products and dazomet have shown promise to contain the nemic population.

tamnara a new full ripe tomato for Protected Cultivation
Horticultural Science & Technology, 2004Co-Authors: Haeboong Jeong, Miae Cho, Namjun Kang, Hojeong Jeong, Hoetae Kim, Kwangyoon KangAbstract:‘Tamnara’ is a newly bred full ripe tomato cultivar for Protected Cultivation. This cultivar was originated from selfing of ‘Daniella’ and selected by means of pedigree breeding. ‘Tamnara’ is an indeterminate type with fairly long internode. It bears round flat fruits and yellow skin color with red flesh fruit. The number of locule are 2 or 3. The soluble solid contents has been in excess of 6.0 Bx. It is resistant to tomato mosaic virus, Fusarium wilt and moderately resistant to leaf mold disease. This cultivar can be cultivated in the Protected Cultivation area everywhere in Korea.

aragaya a new cluster type tomato for Protected Cultivation
Horticultural Science & Technology, 2004Co-Authors: Haeboong Jeong, Miae Cho, Hoetae Kim, Ilrae Rno, Jaewoan Cheong, Kwangyoon KangAbstract:‘Aragaya’ is a newly bred cluster-type tomato for Protected Cultivation. This cultivar was developed from a single cross between ‘GCR26’ and ‘Momotaro-york’ was selected by pedigree breeding. ‘Aragaya’ is an indeterminate type cultivar, and has fairly short internode. It bears round fruits that have colorlesss skin and red fruit flesh. The number of locule is 2 or 3. The soluble solid contents of the fruits are about 7 Bx. It is resistant to tomato mosaic virus, fusarium wilt and moderately resistant to leaf mold disease. This cultivar can be planted in the Protected Cultivation area anywhere in Korea.

Offseason vegetable production under Protected Cultivation
International Journal of Engineering & Science Research, 2019Co-Authors: Indore Navnath, P Kannuji, S J Kale, N PandaAbstract:Not AvailableIndia with the 329 million hectares of the geographical area the country presents a large number of complex agro-climatic situations.India is the second largest producer of vegetable crops in the world. Vegetable Cultivation practices in India have been generally restricted to regional and seasonal needs. Although the production of vegetables has increased from 58.5 million tonnes to 175 million tonnes since 1991-92 to 2016-17 still the technology used and practices followed are pre-dominantly traditional resulting in low yields and inconsistent quality and quantity of produce supplies to the markets. Protected Cultivation or greenhouse Cultivation is the most contemporary approach to produce mainly, horticultural crops qualitatively and quantitatively. Greenhouse Technology is the technique of providing favourable environment condition to the plants.ICAR AICRP PE
