Jajar legowo 4:1 cropping pattern has been adopted by rice farmers; however, there has been limited information on the comparison between internal and edge rows. In addition, the effects of timing and frequency of fertilizer applications on rice cultivated at riparian wetland also have to be understood. In this research, both single and split applications of fertilizer were employed. The single fertilizer applications were applied at 15 days after transplanting (DAT) (T1), 30 DAT (T2), 45 DAT (T3); and the split applications were 15+30 DAT (T4), 15+45 DAT (T5), 30+45 DAT (T6), and 15+30+45 DAT (T7). Results of this research indicated that crops in the edge rows produced higher leaf area index but those at internal rows produced higher dry weight biomass. Split fertilizer application to three times (T7) increased the weight of grains and number of filled spikelet but did not affect other shoot and root growth traits. Overall, fertilizer application increased leaf chlorophyll and nitrogen content. Jajar legowo 4:1 planting pattern and split fertilizer application to three times are recommended for increasing yield in rice cultivated at riparian wetlands.

“…Sub1A, a major quantitative trait locus (QTL) responsible for submergence tolerance, has been widely studied in FR13A rice (Oryza sativa L.) and is considered to confer submergence tolerance in rice breeding [11][12][13]. It has been introgressed into the high-yielding rice variety Inpari30 that did not result in any significant trait differences compared to the parental variety (Ciherang) under normal conditions [14][15][16]. Other studies reported the effect of submergence on shoot elongation in 15 genotypes of Oryza sativa under 80 cm water depth for 7 days.…”

Regulation of non-structural carbohydrates (NSCs) are important for plants in response to submergence. In this study, the difference in non-structural carbohydrates in relation with shoot elongation between Sub1A and non-Sub1A rice genotypes was investigated. Two rice genotypes, namely Inpari30 (Sub1A genotype) and IR72442 (non-Sub1A genotype), were submerged completely for 6 days and re-aerated by lowering water level up to stem base for 6 days of post submergence. In addition, non-submerged plants (control) was treated with water level up to stem base during the experiment. Photosynthesis rate decreased in both submerged Inpari30 and IR72442 genotypes 71% and 96% lower than their control, respectively. Submerged IR72442 declined Fv/Fm 15.6% lowest than its control and both control and submerged Inpari30. Investigation of the distribution of starch and soluble sugar content in plant organs suggested that shoot elongation of non-Sub1A genotype led to starch and sugar consumption that distributed faster to the new developed organ during submergence. In contrast, Sub1A genotype of Inpari30, which did not exhibit shoot elongation and showed slower NSCs distribution during submergence, performed better on post submergence by maintaining NSCs and distributing to the new developed organ faster than IR72442. These results suggest that Sub1A genotype managed elongation and NSCs during submergence more efficiently than non-Sub1A genotype.
