| dc.description.abstract | INDI SAJIWO: Determination of Value of Evapotraspiration And plant coefficient
some rice of variety In the Faculty of Agriculture, University of North Sumatra
Green house. Supervised by SUMONO and LUKMAN ADLIN HARAHAP.
The water requirement of rice crop is compose of saturation,
percolation, flooding and evapotranspiration. The amount of evapotranspiration
can be determined based on the value of potential evaporation and the rice crop
coefficient values for each period of growth. This study was aimed to assess the
value Evapotranspiration and coefficient of Situ Bagendit, Ciherang and
Mankongga Variety In Green house.
The results showed that the value of the evapotranspiration varieties of
rice plants in Situ Bagendit, Ciherang and Makongga was the vegetative phase
1,68 mm/hari,1,68 mm/hari and 1,69 mm/hari, reproductive phase 1,83 mm/hari,
1,72 mm/hari and 1,76 mm/hari, the phase of ripening 1,71 mm/hari, 1,69
mm/hari and 1,70 mm/hari. The coefficient varieties of rice plants in Situ
Bagendit, Ciherang and Makongga was the vegetative phase 1,20 mm/hari,1,20
mm/hari and 1,21 mm/hari, reproductive phase 1,14 mm/hari, 1,07 mm/hari and
1,08 mm/hari, the phase of ripening 1,05 mm/hari, 1,03 mm/hari and 1,05
mm/hari. Ciherang varieties have a value of grain production are higher
compared with the variety Situ Bagendit and MakonggaThe Productivity of rice
was Situ Bagendit 102,81 gram, Ciherang 124,16 gram and Makongga 94,48
gram | en_US |
