Field scale gravimetric studies conducted at Pune [India] for 2 seasons indicated that the soil moisture depletion during the period between 2 consecutive irrigations increased from the 1st period to the last period of irrigation in the soil layers for all the water use factors. Total soil moisture depletion from 1st irrigation to maturity was greater from the 30-60 cm layer at most of the water use factors. With the increase in the water use factor, the total soil moisture depletion from both layers increased. Total soil moisture depletion was minimum during the early growth period, then gradually increased and was maximum during the period from last irrigation to maturity in all the water use factors. In moisture extraction patterns from 0-30 and 30-60 cm soil layers during different irrigation intervals from 1st irrigation to maturity for different water use factors, no regular trend was observed. The total soil moisture extraction pattern from 1st irrigation to maturity showed that out of the total soil moisture extracted from both layers, a higher percentage was extracted from the 0-30 cm layer in different water use factors. The water use efficiency generally decreased with the increase in the number of irrigations scheduled per different water use factors in both seasons.
