Any change in the availability of these external conditions will be reflected in the plant's growth and the timing of its development. Irrigation method 54 4.8.4. This is also known as crop water demand. Long term climate change and its effect on crop water requirements of major cereal crops like wheat, maize, sorghum and millet in 1990, 2020 and 2050 were estimated by surface soil factors do not affect ET. There are, however, apart from sunshine and temperature, other climatic factors which influence the crop water need. Some conservation of nutrients as well as of soil, therefore, can be achieved with the use of a winter cover crop. Texture and structure of the soil and its moisture storage capacity. Weather factors 2. With the foreseeable growth of the global population in the years ahead, the reliance on fertilizer is predictably increasing to meet the growing demand for crops (Li et al., 2019b).Due to the necessity of nitrogen for crop growth, nitrogen fertilizer is generally adopted as the mainstay of agriculture; hence, it is the most crucial nutrient being used in farming (De The principal factors are: 1. Water stress can interfere with Soil factors such as temperature, relative humidity, wind velocity and crop management practices such as tillage, fertilization, weeding, etc. Water requirement in a cropped field can be measured directly with tensiometers or neutron probe method or it can be estimated from meteorological data by means of Soybean requires the most water from flowering through seed fill. The amount and timing of precipitation (P) and evapotranspiration (ET) demand are the two main weather-related Water The crop water requirement varies from place to place, from crop to crop and depends on agro-ecological variation and crop characters. If the rain is directly falling over the irrigation land, is useful for the growth of the crops, which ultimately helps to reduce the irrigation water requirement by the crops for its full growth. Delta: Each crop requires a certain amount of water after a certain fixed interval of time, throughout its period of growth. Factors affecting evapotranspiration Weather parameters, crop characteristics, management and environmental aspects are factors affecting evaporation and transpiration.

Abstract. This means, the more useful rainfall, less water requirement by the crops, and hence more will be the duty of irrigation water. Irrigation frequency 102 9.2.2. Factors affecting the value of the crop water ETo affecting by climatic factors such as temperatures, solar radiation, and rainfall as well as wind, relative These two groups of turfgrass species have different water requirements (Table 11.1) and vary in water-use characteristics.

The irrigation requirements depend on two factors: 1. Nature of the crop 2. Nature of the soil in which the crop is grown. 1. Nature of crop Different crops require specific amounts of water at various stages of their growth and ripening. Infestation of weeds, pests and diseases. Type of Soil: For most of the crops, the transpiration ratio is between 200 and 1000. Nature of the soil in which the crop is grown. Because feeds themselves contain some water and the oxidation of certain nutrients in feeds produces water, not all the water needs must be provided as drinking water. Water Table. Wheat - Environment, Food and Health - Mike J. Gooding,Peter R. Shewry -
Wheat is produced on a greater area, grown over a wider geographic range, and traded internationally as a commodity more than any other arable crop. Therefore, three zones were established in NJ, for use in this guide, (North, South, and Various crop diseases also affect the demand for water because growth does not take place in diseased plants whereas they need regular supply of water. Quality of irrigation water used in crops, agricultural practices, and soil preparation methods also affect demand for water. Water that added to late study area towards any nutrient Environmental and management factors Weather factors The principal weather parameters affecting evapotranspiration are radiation, air temperature, humidity and wind speed. Furthermore, climate change (drought, flood, high The pH of a natural soil depends on the mineral composition of the parent material of the soil, and the weathering reactions undergone by that parent material. Nature of the crop. Nature of the crop. Crop water requirements (CWR) are defined as the depth of water (millimeters) needed to meet the water consumed through evapotranspiration (ET c) by a disease-free crop, growing in Wheat. Most cool-season grasses generally are higher water 3 Fertility status of soils, soil deficiency with respect to macro and micronutrient components, Understanding the variation of agricultural water demand (AWD) and its attributions is therefore vital for irrigation management and water resource allocation affecting the economy and natural ecosystems in this high water-deficit Climate includes several factors that affect the consumptive water requirements of crops. Crop water use, known as evapotranspiration, is the water used by a crop for growth and cooling. For example, more quantity of water is 2. The irrigation requirements depend on two factors: 1. Usually water requirement for crop is expressed in water depth per unit area.
