Assessment of the degree of favorability of agroclimatic and soil-reclamation conditions of the Sanaa basin to the agricultural requirements of the main crops
The main objective of the study is to determine the agro-economic requirements of leading agricultural crops to agro-climatic and soil-reclamation conditions, for the subsequent identification of possible areas of cultivation in the conditions of rain-fed and irrigated agriculture of the Sanaa basin. The data available in scientific sources on the agro-economic requirements of leading agricultural crops are summarized, the long-term experience of farmers within the boundaries of mountainous natural and agricultural areas is studied, and additional studies of the requirements of leading agricultural crops to the environmental conditions of the basin of Sana'a, including the duration of the growing season, average sowing time and planting, temperature and light conditions, soil conditions, fertilizer needs, sensitivity to salinization, water needs, the depth of the root system by stages of development. The data obtained on the agro-economic requirements of the leading agricultural crops were compared with the land, agro-climatic and soil-reclamation conditions of the mountainous natural and agricultural areas of the Sanaa basin. Conclusions are drawn about possible areas of cultivation of leading agricultural crops in the conditions of rain-fed and irrigated agriculture.
