Grain yield, water-use efficiency, and physiological characteristics of rice cultivars under drip irrigation with plastic-film-mulch

The increased competition for water resources has intensified search for the most efficient water-saving techniques and water-use efficient cultivars. A 2-year field experiment was conducted to determine grain yield, grain quality, andwater-use efficiency (WUE) in rice (Oryza sativa L.) under drip irrigation with plastic-film-mulch. Koshihikari (a lowland Japonica cultivar), Norin 24 (an upland Japonica cultivar), and Princessari (a lowland...
