Irrigating BasedonBased on Estimated Crop Use • Crop water requirements. Crop Threshold EC in irrigation water in mmhos/cm or dS/m B a s u d e v S h a r m a M.Sc.Ag. Adjusting weed control strategies based on these factors and observing and avoiding potential threats will help you stay ahead of weed problems. These values should be considered only as guidelines, since crop management and site specific conditions can affect salinity tolerance. Most vegetable crops will not compete effectively against heavy weed growth. Post Harvest Management of Vegetables Crops 1. Transferring water between regions will play an increasingly important role for providing flexibility in water management. For example, in irrigation water at Carnarvon, only about half the total soluble salt is sodium chloride. MSU manual number: E2160; Prepared by: Rebecca Hines Prepares you for: Category 1B on Vegetable Crop Pest Management Date New: March 2002 Size: 114 pages, printed copy; PDF format - 4.56 Mb Cost & availability: $16 or free online.Printed copies can be purchased from the National Pesticide Safety … Vegetable crops utilize and transpire more water in the later stages of growth during which moisture stress markedly reduces yield. The chapter describes the major sites of open-space vegetable farming in Ghana’s main cities. This method is suitable for all row crops and for crops that cannot stand in water for long periods (e.g. Yields frequently are reduced by weeds competing with vegetables and other crops for water, nutrients, and light. Irrigation systems used for vegetable crop production include surface irrigation (furrow, seepage, flood), overhead irrigation (Figure 1), and drip irrigation. Chapter 6. Mechanical harvesting may be impossible. Salts in irrigation water are mainly common salt (sodium chloride), calcium and magnesium bicarbonates, chlorides and sulphates. A guide for integrated nutrient management FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome, 2006 FAO FERTILIZER AND PLANT NUTRITION BULLETIN 16 by R.N. Nutrient Management in Vegetable Crops Dr. Tom Thompson Dept. Vegetable crops require more total water and more frequent irrigation than most agronomic crops. Characteristics of Open-Pollinated (OP) and 153 Hybrid Seed 2. for most ground-grown vegetable crops (Hartz, 1993); where crops are staked or trellised this system is less appropriate. Principles and Practices for Sustainable Water Management in Farming Production (version 2010) Water is a vital component of agricultural production. Hence water management is plan for the use of water for better utilization in agricultural. Using the water budget approach, crop water requirement is calculated: [(Ep or ETo) - ER] x Kc = D When food and water reserves are exhausted, produce dies and decays. Good drainage is especially important for early vegetables because wet soil retards development. 2 • WATER QUALITY/QUANTITY BEST MANAGEMENT PRACTICES FOR FLORIDA VEGETABLE AND AGRONOMIC CROPS FDEP may develop and adopt Basin Management Action Plans (BMAPs), which contain the activities that affected interests need to undertake to reduce point and nonpoint source pollutant loadings. Vegetable water requirements vary from 20 to over 40 acre-inches (543,000 to 1,086,000 gallons per acre) for each growing season, depending on kind of vegetable grown, production location and environmental conditions. Sands are valuable in growing early vegetables because they are more readily drained than the heavier soils. Crop productivity and water and nutrient use efficiency in humid and subhumid areas 109 Wade E. Thomason, Abdoulaye Mando, André Bationo, Maria Balota and William Payne Chapter 7. Lower-volume water sources can be used because trickle irrigation may require less than half of the water needed for sprinkler irrigation. There are a number of ways that careful irrigation management can help you reduce weed pressure on your crops: •Pre-germination of weeds. Critical soil moisture periods of crops All the stages of growth is equally sensitive to soil moisture stress for crops where vegetative parts are of economic importance. We will be spending most of our time learning the elements of successful vegetable production including the what, where, when and how of growing specific crops. Powerpoint presentation at the "Inches to Hours: An Irrigation Workshop for Foothill Wine Grape Growers" meeting. of Soil, Water, and Environmental Science Presented at 14th Annual Desert Crops Workshop Holtville, CA 3 December, 2003 Effective water management is key to controlling weeds in a vegetable operation. Soil Temperature Conditions for Vegetable 155 Vegetable farming - Vegetable farming - Soil preparation and management: Soil preparation for vegetable growing involves many of the usual operations required for other crops. Maturity indices, harvesting, handling, grading of fruits, vegetables, cut flowers, plantation crops, medicinal and aromatic plants. With less water available, agricultural communities will need to become more creative in managing water. – 1 acre inch is 27,000 gallons of water – UllUsually 33‐50% of ldland is didrip ii tdirrigated • Crops that require 1 inch of water/wk need 13,500 gallons per acre • Peak Et c (water use) usually 020.2 – 030.3 in /dayin./day.
