Tolerance of vegetable crops to salinity

Global constraints on water supplies and therefore the got to eliminate agricultural, municipal, and industrial waste waters have intensified interest in water reuse options. In many instances, the worth of the water is decreased solely due to its higher salt concentration. Although quantitative information on crop salt tolerance exists for over 130 crop species, there are many vegetables which lack definitive data. Vegetable crops are defined as herbaceous species grown for human consumption during which the edible portions contains leaves, roots, hypocotyls, stems, petioles, and flower buds. The salt tolerance of vegetable species is vital because the cash value of vegetables is typically high compared to field crops. during this review some general information is presented on how salinity affects plant growth and development and the way different measurements of salinity in solution cultures, sand cultures, and field studies are often reconciled to a standard basis.

Producing vegetable crops.

This book deals with the principles, production practices, management and handling of vegetable crops, with particular regard to the USA. There are 13 chapters on specific subjects: The Vegetable Industry; Classifying Vegetables; Plant Growth and Development; Breeding and Improving Vegetables; Crop Establishment: Transplanting and Direct-Field Seeding; Soil Management and Fertilization; Weed Management in Vegetables; Irrigating and Mulching; Controlling Insects and Diseases; Postharvest Handling of Vegetables; Biotechnology and Genetic Engineering: New Directions in Agriculture; Controlled Environment Vegetable Production; and residential Vegetable Gardening. an extra 17 chapters cover the assembly of specific crops or crop groups (including beans, Brassica spp., peas, onions, lettuces, cucumbers, Capsicum spp., potatoes, spinach, sweetcorn, tomatoes, melons and carrots). The appendix includes tables of the composition and vitamin and mineral contents of over 40 vegetable crops and there’s a glossary. A teacher’s manual (40 pp., ISBN 0-8134-2904-8) to accompany this book is additionally available. [2]

Chromium accumulation, translocation and chemical speciation in vegetable crops

Trivalent chromium (Cr3+) is important for animal and human health, whereas hexavalent Cr (CrO4 2−) may be a potent carcinogen and very toxic to animals and humans. Thus, the accumulated Cr in food plants may represent potential health hazards to animals and humans if the element is accumulated within the hexavalent form or in high concentrations. This study was conducted to work out the extent to which various vegetable crops absorb and accumulate Cr3+ and CrO4 2− into roots and shoots and to determine the various chemical sorts of Cr in these tissues. Two greenhouse hydroponic experiments were performed employing a recirculating-nutrient culture technique that allowed all plants to be equally furnished with Cr in the least times. within the first experiment, 1 mg L−1 Cr was supplied to 11 vegetable plant species as Cr3+ or CrO4 2−, and therefore the accumulation of Cr in roots and shoots was compared. The crops tested included cabbage (Brassica oleracea L. var. capitata L.), cauliflower (Brassica oleracea L. var. botrytis L.), celery (Apium graveolens L. [3]

Interspecific hybridization, polyploidization and backcross of Brassica oleracea var. alboglabra with B. rapa var. purpurea morphologically recapitulate the evolution of Brassica vegetables

Brassica oleracea and B. rapa are two important vegetable crops. Both are composed of dozens of subspecies encompassing many varieties and cultivars. Synthetic B. napus with these two plants has been used extensively as a search model for the investigation of allopolyploid evolution. However, the mechanism underlying the explosive evolution of many sorts of B. oleracea and B. rapa within a brief period is poorly understood. within the present study, interspecific hybridization between B. oleracea var. alboglabra and B. rapa var. purpurea was performed. The backcross progeny displayed extensive morphological variation, including some individuals that phenocopied subspecies aside from their progenitors. Numerous interesting novel phenotypes and mutants were identified among the backcross progeny. The chromosomal recombination between the A and C genomes and therefore the chromosomal asymmetric segregation were revealed using Simple Sequence Repeats (SSR) markers. [4]

Diversification towards Vegetable Crops: A Good Option for Doubling the Farmer’s Income

The present study was conducted to research the rationale that diversification towards vegetable production is taken as a pathway for increasing farmer’s income also as employment. during this study the trends in area, production and productivity of the vegetables in India and Punjab along side their compound annual rate of growth are calculated. The study was undertaken on a macro framework supported data collected from secondary source like The results indicated that production of vegetables in total also because the major cultivated vegetables i.e., potato, tomato and peas in Punjab and India had increased over the last 26 years thanks to increase in area and yield of the respective crops. thanks to such notified increment, the vegetables are often taken as a really good option for the diversification from the culturally practiced crops and thereby will certainly promote the rise in income of farmers. But some factors like increasing rate of post harvest losses, poor conditions of contract farming et al. are forming limiting factors for the particular amount of arrival of vegetables to the buyer .
