Figure 1 classifies the various types of drainage systems. It shows the field (or internal) and the main (or external) systems. [2] The function of the field drainage system is to control the water table, whereas the function of the main drainage system is to collect, transport, and dispose of the water through an outfall or outlet. In some ...
Deficit irrigation (DI) is a watering strategy that can be applied by different types of irrigation application methods. The correct application of DI requires thorough understanding of the yield response to water (crop sensitivity to drought stress) and of the economic impact of reductions in harvest. [1]
Agricultural chemistry embraces the structures and chemical reactions relevant in the production, protection, and use of crops and livestock. Its applied science and technology aspects are directed towards increasing yields and improving quality, which comes with multiple advantages and disadvantages. [1]
A crop is a plant that can be grown and harvested extensively for profit or subsistence. [1] In other words, a crop is a plant or plant product that is grown for a specific purpose such as food, fibre, or fuel. When plants of the same species are cultivated in rows or other systematic arrangements, it is called crop field or crop cultivation.
An agronomist, field-sampling a trial plot of flax. This topic of agronomy involves selective breeding of plants to produce the best crops for various conditions. Plant breeding has increased crop yields and has improved the nutritional value of numerous crops, including corn, soybeans, and wheat. It has also resulted in the development of new ...
The organisation of individual plants in a field is also variable and typically depends on the crop being grown. Many vegetables, cereals, and fruits are grown in contiguous rows , which are wide enough to allow cultivation (or mowing, in the case of fruits) without damaging crop plants.
Reduced tillage [note 1] leaves between 15 and 30% crop residue cover on the soil or 500 to 1000 pounds per acre (560 to 1100 kg/ha) of small grain residue during the critical erosion period. This may involve the use of a chisel plow, field cultivators, or other implements.
The selection in these crops is restricted to the material introduced from other sources, such as field plantations. The improvement of asexually propagated plants through induced mutations has distinct advantages and limitations. Any vegetative propagule can be treated with mutagens and even a single desirable mutant or a part of a mutated ...
