The main parameters of the irrigation regime in the cassava crop clone Miss

M. Portuondo, Ortega E. The main parameters of the irrigation regime in the cassava crop clone Miss

Irrigation and Drainage Series, 1986, Cuba

It was studied the basic parameters of the irrigation regime of cassava clone Miss, in a red Ferralitic soil, at the Experimental Station of Irrigation and Drainage in the province of Havana. It was found that:The real evapotranspiration ranged from 696 to 840 mm for the different treatments under study in a crop cycle of 270 days, with maximum water requirements ranging from 3.70 and 4.70 mm / day. The phases of increased water consumption were: root development, tuber leaves and accumulation of reserves, which represent between 71 and 76% of total consumption.

It is recommend to irrigate with a soil moisture of 80% of field capacity during the first 30 days of wetting at a depth of 0.20 m, then it must irrigate with a depth of 0.40 m to 30 days before harvest field with a capacity of not less than 70%. The total crop water requirements was of  2972 m3 / ha, obtaining a yield of 41 t / ha.
