The current work was carried out in the Agriculture Experimental Stations of Domboshawa, Harare and Marondera in Zimbabwe, for studying the water requirements of some field crops; wheat, barley, maize, potatoes, sugar beet, cowpea, soybeans and sunflower grown in Domboshawa and Harare regions ...

The irrigation and nitrogen (N) requirements of potatoes (cv. Delaware) were determined using sprinklers in a linesource design on a Spearwood sand. Irrigation water was applied at 73 to 244% of the daily pan evaporation (Epan) and N at 0 to 800 kg N ha1 (total applied) as NH4NO3 in...
The water requirements depend on various facts. An obvious one is the amount needed for household use in baths, showers, washing-machines, toilet and so on. The amount of water used in industry is greater than in the houses. Textile works are major users. A lot of water is also used ...
regulated by auxin signaling pathways, however, in addition, diverse factors including early tuber initiation, elevated nitrate concentrations, and plant age collectively suppress further root growth, ultimately leading to the reduced root length density observed in potatoes [15]. Thus, besides breeding ...
After about three weeks,the rooftop garden is ready for planting.Put the seeds directly into the wet grass cuttings.This garden is a good place to grow peas,tomatoes,beans,onions and lettuce.If the box is deep enough,potatoes and carrots will also grow. It is important to keep the grass ...
Potatoesreviewsroot cropswater managementwater stressThe increased use of high frequency, sprinkler irrigation programs, particularly those with early season requirements for maintenace of high soil moisture levels, can mean increased tuber yields and quality, and reduced incidences of common scab. However...
The University of California Center for Water Resources appointed a workgroup with the charges: (1) to review the development of steady-state analyses and transient-state models, (2) to answer the question, “Do the current recommended guidelines on leaching requirements (based on steady-state an...
Plant physiologists have yet to develop a method of expressing the free energy content of water which satisfies all requirements, but it has become customary to use water potential (Ψ). In spite of some theoretical problems, water potential has proved to be a powerful tool in the exploration ...
Table 1 also summarizes the mean net irrigation requirements for the eight scenario model runs conducted within this study (see Chapter 2.3). The first two scenario model runs have been driven with the A2 model output from two GCMs, IPCM4 and MIMR. The socio- economic drivers, here ...
