Determination of irrigation interval for sugarcane by monitoring changes
in soil moisture in the field at the Guneid Scheme
Hassan S.
Ibrahim
Abstract:
A field trial was conducted for two consecutive seasons during the
period 1974 to 1977 at the Guneid Sugarcane Research Station on a heavy
cracking clay (Vertisol). The objective of this experiment was to study
the effects of irrigation intervals on sugarcane during summer and
winter seasons. There were three irrigation treatments, namely M1:
irrigating sugarcane when 40-50 % of the available soil moisture was
depleted; M2: irrigating sugarcane when 80-90% of the available soil
moisture was depleted and M3: irrigating sugarcane when 90-100% of the
available soil moisture was depleted.
Intensive cane growth was observed from April to August while from
August to maturity the rate of growth decreased. Irrigation treatments
significantly affected the length of the irrigation intervals, number of
irrigations, cane and sugar yields and the percentage sucrose recovery.
Treatment M1 gave the highest cane yield in both seasons. Irrigation
intervals for plant cane are recommended for the winter and summer
seasons in this paper.
Delaying irrigation beyond 70% depletion of available soil moisture is
detrimental to the growth of sugarcane and will result in economic
losses of sugar yield.
