In upper Galilee a field of alfalfa was sown in April 1965 in order to study the influence of the quantity of irrigation on leaf structure and on yield. Three treatments were given, each on five experimental plots: 1) Irrigation, with 5000 m 3 per ha; 2) Irrigation with 10,000 m 3 per ha; and 3) non‐irrigated. Leaves were picked four times during 1965/66, each time after the field had been cut and after the regrowth had developed. The following conclusion can be drawn from the results. Each regrowth shows changes in the number of stomata and epidermis cells, in the length of stomata, and in leaf area as a result of the three treatments and of the changing environmental factors during the period of development of the four regrowth leafages. The greatest modification was noted in the non‐irrigated experimental plots of highest stomata density; the least modification in plots with 1000 m 3 per ha irrigation. The results show that there is a relationship between modification of stomata and changes in edaphic and climatic factors.
