   The growth of the rice plant is divided into three stages: 1. vegetative (germination to panicle initiation); 2. reproductive (panicle initiation to flowering); and. 3. ripening (flowering to mature grain) Roll your mouse over the colored boxes. Note: In the tropics, the reproductive stage is about 35 days and the ripening stage is about 30 days.

   Rice has three main growth stages; the vegetative, ripening, and harvest stages. It is an annual and semi-aquatic plant. The rice plant is characterized by one major stem with a lot of tillers, each having a panicle. A panicle is a flowering head terminal. It can also undergo ratooning, which is the process of producing nodes from the tillers ...

   Depending on the weather, an additional two weeks are required for moisture content to drop to around 20 percent and the grain to ripen. Knowing, understanding and identifying the growth stages of rice are critical in managing the rice crop. Most cultural management practices after planting are based on crop growth stages.

   ripening phase-from anthesis to full maturity These main phases overlap each other within a rice hill or a rice crop. Physiologically, ripening does not begin until 3 weeks after fertilization. Figure 2-1 illustrates the growth behavior in the tropics of a cultivar (IRS) maturing in 120 days compared with one (Peta) maturing in 150 days.

   the rice plant during the seedling stages of growth. Tillering Tillers (stools) first appear as the tips of leaf blades emerging from the tops of sheaths of completely developed leaves on the main shoot. This gives the appearance of a complete leaf that is producing more Fig. 4-7. Rice seedling root system. than one blade (Fig. 4-8).

   Why does rice ripen in the tropics?

   • In the tropics, the rice plant produces more straw than grain. High temperature accelerates grain ripening, resulting in prematurity. The main result is the inability of the spikelet to serve as a sink (Aimi et al. 1959; Nagata et al. 1966; Bhattacharya 1970).

   How long does it take for rice to ripen?

   • Nearly 27 days separate the ripeness (BBCH 89) and overripeness (BBCH 92) of rice. Since the later-developing grains are still filling up and the earlier-developing grains are drying out, the whole field of rice is often harvested before the BBCH 92 rice growth stage. Achieving high rice milling yields relies on uniform ripeness.

   When do rice grains ripen?

   • When rice grains first become firm, they are at the physiological maturity stage. Grain moisture at physiological maturity is around 30 percent. Depending on the weather, an additional two weeks are required for moisture content to drop to around 20 percent and the grain to ripen.

   How long does it take for rice to head?

   • Heading stages are identified by percentages, and the 50 percent heading stage occurs when 50 percent of rice stems are heading or headed (panicle completely emerged from the stem). The flowering and grain filling stages begin within one to five days after heading, and grain filling is complete within three weeks.

   Identification of plant parts is essential in differentiating rice plants from weeds. Rice plant growth can be divided into three agronomic phases of development (Figure 2-3): Vegetative (germination to panicle initiation (PI)); Reproductive (PI to heading); and. Grain filling and ripening or maturation (heading to maturity).
