They are grown to protect the land from soil erosion and loss of nutrients (Reeves, 1994) and to add organic matter to the soil, which can lead to increased soil microbial pop-ulations and diversity (Drinkwater et al., 1995). It is tolerant of drought, thrives in hot weather and is adapted to a range of soil types. Try a mix of species or just one type of plant. Below are some of the drought-tolerant crops and methods farmers across the world are using to combat drought: 1. Choose drought tolerant plants for the vegetable garden. Although it depends on the conditions of the maize growing areas, studies indicated that compared with local varieties, drought-tolerant maize can increase yields by 15%. Most yield trials for new, drought-tolerant commercial products have shown mild yield bumps in water-stressed test crops. ��q�F)9�Cgo�!�k=��9[BE\�+�Xul��������6 hXG�KGGkFG��@ ��y�l;�X$�����o��! While his crops this summer did use some of the moisture in the soil, Henderson says in the end they helped the soil retain more moisture than it could have without the crop. Conservation agriculture and drought-tolerant crops . Plant in groupings or hexagonal offset patterns rather than in rows when growing drought tolerant vegetables. Drought Tolerant Vegetable Varieties. Peanuts are a drought-tolerant crop, and are widely grown in tropical countries, often under conditions of drought stress that promote aflatoxin production. Public Safety Power Shutoffs - How is YOUR Farm Coping? This chapter provides an update on research advances and breeding main grain crops for drought-prone environments. Mungbeans are a short-season legume. endstream endobj 669 0 obj <>>>/Lang(�� E N - U S)/MarkInfo<>/Metadata 38 0 R/Outlines 52 0 R/PageLayout/OneColumn/Pages 666 0 R/StructTreeRoot 67 0 R/Type/Catalog>> endobj 670 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 671 0 obj <>stream Due to its thick succulent leaves, it can survive for a long time without water. Buckwheat's broad leaves and fast growth make it an ideal “smother crop” that will effectively shade out problematic weeds. The vegetables, grains and herbs on the following list were selected from seed catalogs and seed catalog websites that specifically mention the terms “drought-resistant” or “drought-tolerant” in the variety description. Drought tolerant crops — like maize, cowpeas and rice — have been bred through conventional plant breeding techniques or biotechnology and continue to grow and produce even when rains fail. This chapter is intended to cover a broad overview of traits and mechanisms known to play a role in drought tolerance in crop plants. Keywords Drought Stress Water Scarcity Harvest Index Canopy Temperature Carbon Isotope Discrimination These keywords were added by machine and not by the authors. It requires an initial watering at planting but can be dry farmed once established. It makes a large plant and an impressive taproot that can break up compacted soil layers. Recent Impacts in the Islands. Sudangrass has lower concentrations of prussic acid than its relative Sorghum or Sorghum-Sudangrass hybrids but it is still present in the leaves and roots of the plant. Syngenta, Pioneer Hi-Bred and Monsanto Company promise they will have genetic packages with drought tolerance on the market before long. These are very short-season crops and both are high in fiber. ���g��� They need less water for fruit development than their larger cousins. They are adapted to a range of soils and seem to be relatively pest-free. In the continuing quest to develop more resilient grain crops, Australian scientists are investigating the mechanisms that drought-tolerant plants use for survival under water-limited conditions drought-tolerant crops may become a factor to maintain plant growth and pro-ductivity. By growing a drought tolerant, summer cover crop you can productively fallow land during the dry months to conserve water. Sudan Grass is a very drought tolerant, productive warm season crop.
