| Abstract | ||
| The effect of water requirements in the cultivation and production of some vegetable crops (summer and winter) was studied in order to determine the importance of water during the different stages of growth in order to carry out the vital processes, as most of the physiological processes within plants in general are affected directly or indirectly by the presence of water, the research took Abu Ghraib district as a model for the study, as it is one of the important districts that are famous for cultivating vegetable crops that feed the markets of Baghdad , and the research has reached To the fact that moderate soil moisture is important in the germination of crops, as its decrease negatively affects the failure to germination, the failure to elongate peacocks, or the production of incomplete fruits. As for the increase of that moisture, it causes great damage to the vegetable crops, such as their exposure to diseases and pests, as is the case with air humidity, as its decrease leads to Drought and falling branches and leaves, as well as its effect on the increase in the process of evaporation - transpiration, which leads to the withering of crops. As for its height, it leads to the disruption of the pollination process. It was also found that some vegetable crops are well cultivated in high air humidity, such as lettuce, spinach and leafy greens, and that some of them are well cultivated in low humidity. Such as watermelon and watermelon, and it was found that the decrease or high of the fallen rain or irrigation water negatively affected the growth and germination of vegetable crops. | ||
