Morpho-physiological characterization of multi-canopy rice cultivation systems in various genotype combinations

Abstract The multi-canopy rice cultivation system modifies the cultivar mixture using two genotypes with different stem lengths to create heights of plant canopy that may optimize vertical growth and harvesting space. This study aims investigate effect a on morpho-physiological characteristics several genotype combinations. research was conducted in plastic house IPB University experimental station, Dramaga, Bogor, West Java, Indonesia. Two short plants tall as breeding lines were evaluated randomized complete block design. combination transplanted same hill system. results produced number tillers, panicle number, percentage productive tillers showed no difference mono-genotype hills. Meanwhile, genotype’s performance for length, height, density, photosynthesis rate, SPAD value is good These indicated decrease characters’ each grown multi-canopy. Each can utilize resource inputs at positions minimize competition.
