  Author(s): Shaibu Abdul Ganiyu*, Naoko Oka and Seiji Yanagihara
  
  Dry season irrigated rice production in northern Ghana is often hampered by lack of sufficient water in dams and reservoirs to meet the crop and irrigation water requirements under continuous flooding. In some years, rice farmers are forced to change their cropping repertoire and move to vegetable production. This situation calls for development of efficient water application and saving methods on the field. The objective of this study was to assess the effects of different water saving irrigation applications to improve over continuous flooding used on dry season rice fields. Two years of experiments were conducted using a randomised complete block design with 4 replications at golinga irrigation scheme in 2017/2018 and 2018/2019 dry seasons, respectively. The treatments were as follows: Alternate Wetting and Drying (AWD 10) at 10 cm water-table drop below the soil surface; AWD 15 at.. Read More»
