Résumé
An attempt has been made through the agroclimatic approach (water balance technique) to know the soil moisture status of various districts of North Gujarat to provide basis for crop planning in kharif season. The weekly water balances were worked out according to book keeping procedure (Thornthwaite and Mather, 1955) for 5 stations viz., Jagudan, ’Sardar Krushinagar, Talod, Vijapur and Viramgam for a period ranging from 9 years to 15 years. The results revealed that all the stations experienced water deficiency in all the months except few weeks (28th to 35th standard week) of kharif season. The annual water deficiency was varied from 835.3mm at Vijapur to 1080.Omm at Jagudan. The pattern of AST variation in the different weeks of the year was similar to the pattern of P variation. By employing the moisture index (Im) the region under study was divided into 2 sub-groups viz. semi-arid with little water surplus (Sardar Krushinagar, Talod, Vijapur and Viramgam) and arid with no water surplus (Jagudan). The results of the analysis of phasewise values of moisture adequacy index (Ima) showed good correlations with the yield of the crops in different districts of the region. New crops that could be grown in different regions have been suggested on the basis of the consideration of general climate, soil type and the moisture adequacy index jointly for each of the districts served by the respective stations.
