“…For this reason, it is suitable for areas where the annual accumulation of solar radiation and temperature is in excess of the requirements for a single season but not enough for a double season. In addition, a ratoon crop saves seed costs and approximately 50% of labor and 60% of water costs because it is free of land preparation, seeding or transplanting, unlike the MC (Flinn et al, 1988;Oad et al, 2002); thus, ratooning is the most suitable cropping system in areas where labor and water are in short supply. Due to its shorter cropping duration, fewer inputs, such as fertilizer and pesticides, are needed in RCs.…”

The ratoon rice system is an energy-saving, high-efficiency cultivation method. Harvests from a two-year field trial with a main crop (MC) and a ratoon crop (RC) were used to evaluate milled grain quality traits and yield performance. The results indicated that chalkiness was significantly lower in the RC than in the MC. Chalkiness ranged from 1.90 to 15.01%, with an average of 6.46%, in the MC and from 0.66 to 3.28%, with an average of 1.50%, in the RC across two years. In addition, nearly all of the RC of the test entries had lower white vitreous (higher translucency) than the MC of the same entry. In 6 of the 20 entries, the MC had longer or wider milled grain than the RC in 2017. The milled rice recovery for the MC was higher in both years, but there was no difference in head rice recovery within the same year. The average total yield (MC+RC) in the two years was 12.6 and 13.0 t/ha, and the two-year average RC yields were 47.5 and 37.3% those of the MC. Our results revealed that the RC milled grains showed better appearance quality than the MC grains, and several genotypes had comparable or even better milled grain quality and yield compared with the check entries that were suitable for the ratoon rice system.

Numerous studies have attempted to pinpoint certain traits of rice varieties linked with great ratooning ability that may be used in cultural practice. However, both genetic and environmental variables affect rice's capacity for ratooning. We are able to measure the innovative ratooning ability that affects the decline in ratoon yield using the agronomic features of the main crop and ratoon rice in our global database for a meta‐analysis, drawn from 51 experiments in 14 countries. We discovered that changes in cultivar yield and maturity features, cropping location, and nitrogen fertilizer treatment may all affect a plant's capacity to tiller. On the other hand, the growth duration ratoon ability was less responsive to variations in cultivars and cropping location. We also found that ratooning changes the plant architecture for yield generation from bigger spikelets with fewer panicles to fewer spikelets (dropping 48%) with larger panicles (increasing 19%). We came to the conclusion based on our research that the decreased yield in ratoon crops may be caused by fast ear emergence and aggressive tillering, which negatively influence stem elongation, panicle differentiation, and a lack of nutrition, resulting in fewer spikelets per panicle. The present data are thoroughly summarized and analyzed in this research, which also clarifies the lack of knowledge around the characteristics that affect ratoon rice crop production.This article is protected by copyright.

“…The rice ratoon system has more advantages than the conventional rice cultivation system, including the minimized application of soil tillage (Fitri et al, 2019); conservation of water; reduction in agricultural inputs, such as labor input, maintenance costs, fertilizer costs, and weeding costs; and faster harvest times (Oad et al, 2002). However, the rice ratoon system has long been abandoned because it is considered unprofitable (Fitri et al, 2019).…”

<p>Ratoon system is a method of rice cultivation that produces new tillers after the mother plant is harvested and is continued by maintaining and caring for the shoots of the mother plant. In Indonesia, SALIBU and SINGGANG, which are types of rice ratooning, have been developed for Sumatra and Java regions, respectively. SALIBU is an innovation or a modification of the rice ratoon system that focuses on maintaining the time of fertigation and cutting of plant height. SINGGANG, on the other hand, is a rice ratoon system in which the management of fertigation and cutting is not considered. Both systems have not yet been implemented outside their places of origin. This study aims to compare the conventional and modified rice ratoon systems considering parameters such as soil properties, nutrient uptake, and the growth and yield of rice. The effects of rice ratoon systems (SALIBU and SINGGANG,), soil types (Inceptisols, Alfisols, and Vertisols), and cultivars (Pandan Wangi and Mekongga) were evaluated. All treatments were evaluated in a completely randomized design with three replicates in the net house. The results showed that the soil porosity in SINGGANG (48.89%) and SALIBU (46.78%) systems was higher than the conventional system (43.17%) in the Inceptisol soil and Pandan Wangi cultivars. Moreover, SINGGANG had a positive effect on the physical properties of soil (porosity and permeability); whereas, SALIBU had a positive effect on the chemical properties of soil (pH and organic carbon). In contrast, the agronomic parameters showed that the weights of dry matter and dry yield for SINGGANG were 44.96 and 23.09 g per plant clump, respectively, while those for SALIBU were 55.54 and 25.74 g per plant clump, respectively. These were lower than the conventional system (63.18 and 31.21 g per plant clump, respectively). Thus, we concluded that the SINGGANG and SALIBU ratoon systems had a positive impact on soil properties, but both systems could not promote higher rice production than the mother plant in all soil types and cultivars.</p>
