RESPONS ENAM VARIETAS PADI Sawah (Oryza sativa, L.) PADA PERBEDAAN UMUR BIBIT DI LAHAN RAWA (Responses of Six Paddy varieties at Different Age Seedling at Peatland.)

Abstract

This research was conducted to observe the effect of age’s difference
seedling to growth and yield of six Paddy varieties at peatland. The
experiment was arranged in factorial Randomized Block Design with
three replications. The first factors were time of age seedling (3, 4, 5, 6
weeks), and the second factors were six cultivars of paddy (Cisokan, IR-
42, IR-64, Batanghari, and two local cultivars, there are Ceko dan
Kuatik). The data were analyzed with ANOVA and DMRT. The results
showed that, there no interaction effect between seedling age and
cultivars. Furthermore, there is no simple effect, on relative growth rate
(RGR) and maximum advantity shoots, but signifianly influence to
height of plant and Net Assimilation Rate (NAR), rate of initation and
yield. Cisokan and Batanghari cultivars were showed the highest yield
