“…There does not seem to be a consensus on a suitable cutting height to produce a high‐yielding second crop when using the ratoon methods. Some previous studies reported that appropriate cutting height of the first crop for producing higher grain yield of the second crop was 20 cm in Louisiana and Florida (Harrell, Bond, & Blanche, 2009; Jones, 1993), whereas other studies reported that it was 40 cm in Sari, India, and South Sumatra, Indonesia (Mareza, Djafar, Suwignyo, & Wijaya, 2016; Shahri et al., 2012). A more recent modeling study showed that a suitable cutting height of the first crop was 40 cm in China (Ling et al., 2019).…”

Rice (Oryza sativa L.) ratooning has recently attracted attention since it possesses higher yield potential compared to conventional rice-growing methods; however, it requires a longer growing season. Field experiments were conducted in southwestern Japan in 2017 and 2018 to determine the effect of harvest time (early and normal) and cutting height (high and low) of the first crop on grain yield of the first and second crops using a high-yielding line under high N application and high air temperature conditions in rice ratooning. The highest total yield of the first and second crops was produced when the first crop was harvested at the normal time with the high cutting height in 2018. This yield reached 14.4 t ha −1 , which is equivalent to threefold the average yield achieved by Japanese farmers. Plants harvested at the high cutting height produced higher grain yield of the second crop because of the larger spikelet number m −2 and better grain filling using abundant leaf area index (LAI) and nonstructural carbohydrate (NSC) in the stubble. In southwestern Japan, the daily mean air temperatures during the early growth stage of the first crop and the late ripening stage of the second crop have been increasing over time. Our results suggest that increasing LAI and NSC in the stubble by harvesting at the normal time harvest with the high cutting height under high level N application conditions may provide an adaptive strategy to increase yield with a rice-ratooning system as growing seasons extend due to global climate change. 1 INTRODUCTION Global average temperatures increased by 0.85 • C between 1880 and 2012 (IPCC, 2014).

“…Susilawati et al (2012) stated that the height and number of productive tillers for ratoon rice in genotype IPB106-F-8-1 at a 10 cm cutting was higher than that at 20 cm and 30 cm cuttings. Mareza et al (2016) stated that cutting 40 to 50 cm of the main rice stem was significant for the number of productive tillers, with the highest found at the 40 cm cutting (6.55 tillers) compared to the other cutting sizes.…”

“…which was 108.0 grains higher than the 20 cm and 30 cm cuttings (78.5 and 71.1 grains, respectively). Mareza et al (2016) stated that cutting 10 cm of the rice stems significantly improved the panicle length and the number of grains per panicle of ratoon rice by 14.93 cm and 47.05 grains, respectively, compared to the cuttings of 20 to 50 cm.…”

This study aimed to identify the optimum rice stem cutting size combined with the application of Seprint liquid organic fertilizer (SLOF) to promote the growth and yield of ratoon rice. This research was conducted in a greenhouse at the Faculty of Agriculture, University of Muhammadiyah Sumatera Utara, North Sumatra Province, Indonesia, from January to August 2018. The experiment was set up as a completely randomized design factorial with four replications. The first factor consisted of the cutting sizes of the rice stem (R1 = 5 cm, R2 = 10 cm, and R3 = 15 cm) and the second factor involved the SLOF dosage (S1 = 5 mL L −1 , S2 = 10 mL L −1 , and S3 = 15 mL L −1 ). The parameters were analyzed using analysis of variance (ANOVA), and the means were determined by Duncan’s multiple range test (DMRT). The results showed that the R2 treatment significantly increased the ratoon rice height at 10 to 30 days after cutting (DAC), the number of tillers at 40 to 60 DAC, the number of productive tillers, and the yield per hectare. The S2 and S3 applications at significantly increased the yield per hill and ratoon rice height at 20 DAC. The R2S1 and R2S2 combination treatments significantly increased the number of filled grains per panicle and the ratoon rice height at 10 DAC. Cutting the stems at 10 cm combined with various dosages of SLOF resulted in greater growth and yield of ratoon rice for achieving an adequate food supply.

Tidal swampland in Indonesia is potential for cultivation of inbred and hybrid rice. However, rice cultivation in this land can be done only one time annually. Rice cultivation with ratoon system in this land might increase production from both the main crop and their ratoon. The study aimed to evaluate the ability of hybrid and inbred rice to produce ratoon and their grain yield in the tidal swampland of Central Kalimantan. The experiment was arranged in a randomized block design with 12 rice varieties as treatments, namely six hybrids (Hipa 3, Hipa 4, Hipa 5, Hipa 6, Maro and Rokan) and six inbreds (Batanghari, Ciherang, IR42, Margasari, Mekongga and Sintanur); replicated three times. Cultivation of the main crop followed the recommendation. At harvest, the main crops were cut at 20 cm from the ground and fertilized with 100 kg ha -1 urea. The results showed that ratoon crops were emerged at 5-6 days after cutting, with 2-4 leaves per panicle and 5.5-26.0 tillers per clump. Average harvesting age of the ratoon was 69 days. Ratoon yield of the hybrids was better than that of the inbreds; the average was 75.2% of the main crops. Based on the criteria of rice yield, three clusters were identified, i.e. high (>2 t ha -1 ): Hipa 3, Hipa 4, Hipa 5, Maro, Rokan, Ciherang and Sintanur; medium (1-2 t ha -1 ): Hipa 6, IR42, Margasari and Mekongga, and low, Batanghari. The study suggests that hybrid varieties could be developed in tidal swamplands. ABSTRAKLahan pasang surut di Indonesia sangat potensial untuk ditanami padi inbrida dan hibrida. Namun, penanaman padi di lahan pasang surut hanya dapat dilakukan setahun sekali. Penelitian bertujuan untuk mengevaluasi kemampuan varietas padi inbrida dan hibrida untuk membetuk ratun serta hasil gabahnya di lahan pasang surut Kalimantan Tengah. Percobaan dirancang secara acak kelompok dengan 12 varietas padi sebagai perlakuan, yaitu enam varietas hibrida (Hipa 3, Hipa 4, Hipa 5, Hipa 6, Maro, dan Rokan) dan enam varietas inbrida (Batanghari, Ciherang, IR42, Margasari, Mekongga, dan Sintanur); diulang tiga kali. Budi daya padi mengikuti rekomendasi. Saat panen, tanaman utama dipotong 20 cm dari permukaan tanah kemudian dipupuk urea 100 kg ha -1 . Hasil penelitian menunjukkan bahwa tunas ratun mulai keluar pada 5-6 hari setelah panen, dengan 2-4 daun per malai dan 5,5-26,0 anakan per rumpun. Rata-rata waktu panen tanaman ratun 69 hari setelah panen tanaman utama. Hasil gabah ratun padi hibrida lebih tinggi dibandingkan dengan varietas inbrida dengan hasil rata-rata 75,2% terhadap tanaman utama. Berdasarkan kriteria hasil gabah, 12 varietas dapat dikelompokkan menjadi tiga, yaitu potensi hasil tinggi (>2 t ha -1 ) yakni Hipa 3, Hipa 4, Hipa 5, Maro, Rokan, Ciherang, dan Sintanur); potensi hasil medium (1-2 t ha -1 ) meliputi Hipa 6, IR42, Margasari, dan Mekongga, serta potensi rendah (<1 t ha -1 ) yaitu Batanghari. Penelitian mengindikasikan bahwa padi hibrida cocok dikembangkan di lahan pasang surut.[Kata kunci: kemampuan ratun, padi, lahan pasang surut, sistem ratun]
