“…The multi-canopy cultivation system can also increase productivity by increasing the plant population through the number of row inserts. The multi-canopy cropping pattern has the potential to be developed to produce a more productive total production than monoculture [9]. The criteria for rice plant height based on the standard are short (<90 cm) and tall (>125 cm) categories [10].…”

The use of multi-canopy technology by intercropping and modified ratoon techniques called “salibu” in rice cultivation is expected to have the benefit the increasing yield potency through a vertical harvesting area and cropping index. The purpose of this study was to investigate rice growth and production by the modified ratoon salibu on a multi-canopy cropping system. The multi-canopy was performed by planting a short variety (Inpari 33 and Inpari 43) intercrop with a tall variety (IPB 9G). The short varieties were transplanted with growing space 4:1 with a distance of 30 to 15 cm, and the tall type was transplanted in between rows. After the main-crops were harvested, conventional and modified ratoon salibu were conducted and observed on growth and production. The performance of multi-canopy showed a higher yield compared to that of monoculture. The modified ratoon salibu technique was better than the conventional ratoon in most of the morphological and physiological traits, as well as for grain yield. Utilizing taller rice as intercropping for multi-canopy combined with modified ratoon salibu could be recommended for gaining the benefit of the cropping index as a land utilization strategy.

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

One strategy currently being developed to increase rice (Oryza sativa L.) productivity is using a multi‐canopy cropping system in rice cultivation. This method involves planting tall and short rice genotypes in the same hill. The objective of this experiment was to estimate the genetic parameters and response to selection in multi‐canopy rice. Each experiment was arranged in an augmented randomized complete block design with five replications for the checks. In the first planting season, 200 F3 families from IPB196 and IPB197 populations were planted in monoculture and multi‐canopy as the short genotypes. IPB187‐F‐40‐1‐1 was used in multi‐canopy as the tall genotype. Selection of 25% based on grain weight per hill of short genotype in multi‐canopy was performed, and 50 families were selected and their F4 seeds were planted in the second season along with the same tall genotype. The results indicated the genotype × cropping system was significant for grain weight per hill in the F3 and F4 generations. Grain weight per hill has a similar realized h2ns in the multi‐canopy (0.58) with monoculture (0.54). Meanwhile, the response to selection in multi‐canopy (3.60) was higher compared to monoculture (2.09), and therefore the selection of rice lines for a multi‐canopy system should be conducted in the multi‐canopy environment. A selection percentage of 5% resulted in a higher response to selection. These findings may provide insight into the acceleration of breeding rice varieties for the multi‐canopy system.
