Dikes have recently been constructed in many small valleys in Western Gambia to retain run-off and prevent salt-water intrusion. This study, conducted in 1987 and 1988, describes the groundwater hydrology and soils of three small valleys and assesses the impact of dikes on rice production. ...
Rice is the staple food in The Gambia, with aver-age annual consumption per capita of 70 to 110 kg. Domestic production lags behind consumption by 60%, with the balance needing to be met by importa-tion. National average yields of rice are only 2 t/ha. SRI was introduced to The ...
An opportunity for increasing factor productivity for rice cultivation in The Gambia through SRI farmers could increase their rice production while lowering costs of operation and reducing the need for water by utilizing its principles and practices. This... M Ceesay - 《Paddy & Water Environment》...

production methods, rice yield was further elevated to 6.0 t/ha in early 1990s in China, which was the world level, then. However, the yield ceiling witnessed in various crop species has also been encountered in the rice production in China since 1990. ...
manually emasculated to facilitate cross-pollination. However, manual or mechanical emasculation is impractical for the large-scale production of hybrid seeds for monoclinous crops that have relatively small reproductive organs, such as rice, wheat, and rapeseed (Longin et al.2012). Therefore, the ...

After commercialization for more than 15 years, these A lines still play an important role in hybrid rice production in China. To secure a complete substitution of the nucleus, the four A lines were backcrossed with their corresponding B lines more than 30 times. Seedling culture and DNA ...
