Kajian Beberapa Metode Pemberian Air Padi Sawah (Oriza sativa L) Varietas Ciherang di Rumah Kaca

Abstract

RIZA REVITA PINEM. Study of Various Provison of water paddy Methods (Oryza Sativa L) Ciherang Variety Rice in Green House. Supervised by SUMONO and NAZIF ICHWAN. The provision of water paddy is very influental to rice growth and production. This research was aim to study various provision of water paddy methods (Oryza Sativa L) ciherang variety rice in greenhouse. Parameters that observed was evapotranspiration value, potential evaporation, crop coefficient, percolation, grains weight and dry plant weight. The results show the value of crop evapotranspiration for intermitent method, humid and flooding in a row with an average of 1.54 mm / day, 1.60 mm / day, and 1.71 mm / day. The average value of potential evaporation from vegetative phase to the ripening of 1.62 mm / day. The value of the plant's method of intermitent koevisien , humid and flooding in a row by an average of 0.95, 0.99 and 1.06. The value percolation to intermitent method, humid method and flooding method in a row with an average of 1,83 cm / day, 1 , 3 cm / day and 3.36 cm / day. The plant's dry weight intermitent method, humid and flooding in a row by an average of 87.5 g, 84.1 g and 77.5 g and the weight of grains rice to intermitent methods, humid method and flooding in a row by an average of 50 g, 43.3 g and 30 g.
