Irrigation Water Productivity of Rice under Various Irrigation Schedules and Tillage Practices in Northern Guinea Savanna Region of Nigeria

Abstract

The effect irrigation method and tillage on yield and irrigation water productivity of rice was conducted in split plot experiment with three replications during the dry seasons 2012 and 2013 in field conditions at the Lake Geriyo Irrigation scheme farms in Yola, Nigeria. 3 irrigation management: 3, 6 and 9 day interval with 3 tillage practices: zero, shallow and deep soil tillage were studied. Results showed that there were significant differences in paddy yield, harvest index and irrigation water productivity. 6 days interval irrigation management was placed to one group with 3 days irrigation interval on paddy yield and harvest index; higher water productivity of 3.58 and 3.51 kg ha-1 mm-1 were recorded with 6 days irrigation interval in both seasons respectively. Therefore it can be recommended that 6 day interval irrigation which had better irrigation water productivity and saved up 29% irrigation water be adopted for rice cultivation under clay loam soils of guinea savanna zone of Nigeria.

Socio-Economic Influences on Water Management Practices Among Dry Season Irrigated Vegetable Farmers in Jimeta, Adamawa State, Nigeria

“…The result shows majority of the farmers adopted 2 days interval method of irrigation in the study area, since majority of the farmers adopted the 2 days interval as the method of irrigation, this may be connected to the topography and the weather condition of the study area. Timon, F et al, 2018, worked on different levels of irrigation in rice, his findings reveals that higher yield were gotten in 3days interval, but the difference in yield with 6days interval was not much and the cost of irrigating is not worth expending. It then indicates that the more the interval in irrigation the better all other things being equal, the soil texture, the rate of evaporation.…”
