Effect of different plant spacings on the yield and yield components of rice variety niupela under rainfed upland field conditions at Erap station.

Abstract

Plant spacings did not have any significant (P<0.05) effect on plant heights, panicle length and number of grains per panicle. However, there were highly significant (P<0.01) differences in panicle weights and number of productive tillers between the different plant spacing treatments. At the closer plant spacing of 7 5 x 15cm, a significantly (P<0.01) higher paddy yield of 9.50 t/ha was obtained compared to the other plant spacing treatments.
