There are three seasons to grow rice. These three seasons are named according to the harvest season of the crop.
Autumn Rice / Pre-Kharif Rice
Summer / Rabi Rice
Winter rice / Kharif rice
Rice storage:
The exact answer to the question “How long does rice last?” It depends on the type of rice, whether it is cooked or uncooked, and the conditions in which the rice is stored. Follow these handy instructions to keep this popular dish at its freshest:
Most types of raw rice have an indefinite shelf life. The main challenge is keeping it free of dust, insects and other contaminants.
So exactly how long does rice last if it’s not cooked? All white, wild, arborio, jasmine and basmati rices have an indefinite shelf life, when kept free of contaminants. The exception is brown rice – thanks to its higher oil content, it won’t keep for as long.
Shelf life of raw rice:
Follow these tips for storing raw rice:
– To maximize the shelf life of rice, store it in a cool, dry area; After opening the package, place the uncooked rice in a sealed airtight container or place the original package in a sturdy zip-lock freezer bag.
– For added protection against insects, dust or other contaminants, raw rice can also be stored in the refrigerator or freezer; Place the rice in a sealed airtight container or place the original package in a sturdy zip-lock freezer bag.
– You can know if the rice is bad. If insects or other contaminants are found on the rice, discard the entire package. Spoiled brown rice will often develop an oily texture and develop an unpleasant odor.
Cooked rice:
You wonder how long the rice lasts when it is cooked. The shelf life of cooked rice – all varieties, including white, wild, jasmine, basmati, Arborio, brown – is as follows:
Refrigerator: 4 to 6 days:
Freezer: 6 months (best quality only – food that is constantly kept frozen at 0 ° F will be kept safe indefinitely)
Some tips for storing cooked rice:
– To maximize the shelf life of cooked rice, refrigerate in covered airtight containers.
-Duration of rice cooked at room temperature. Bacteria grow rapidly at temperatures between 40 ° F and 140 ° F; rice should be discarded if left for more than 2 hours at room temperature.
– To further extend the shelf life of cooked rice, freeze it. Freeze rice in covered airtight containers or heavy duty freezer bags.
– How to know if cooked rice is bad? The best way is to smell and look at the cooked rice; Discard any rice with an unpleasant smell or appearance, don’t taste the cooked rice first.
In this study, the productivity in the use of irrigation water (Wp) varied from 1.11 kg m -3 in the treatment (A1) with suspension of the water sheet (noInund) to 0.56 kg m -3in the control treatment (A4); whereas, the WP was increased by effect of the suspension of the water sheet (A1, A2 and A3) by 49.74; 46.32 and 38.24%, respectively, with respect to the control (A4). These results show that there were differences in the behavior of the WP, motivated by the moment in which the wheat thresher machine price was applied.
This behavior made it possible to ensure that the suspension of the water sheet in the vegetative phase contributes to the conservation of the water resource and increases the rice yield based on irrigation. In this regard, it was reported that, as the productivity of irrigation water increases, its use efficiency increases (4, 22).
The highest efficiency in the use of water (Ew) was obtained in the plants that were exposed to suspension of the water sheet at 30 DAT, with values of 889.91 m 3 kg -1 . The productivity and efficiency results are acceptable if we take into account the information reported by other authors who have cultivated rice with intermittent irrigation, without a water layer (aerobic) and under rainfed conditions B (19). On the other hand, it can be stated that the suspension of the water sheet or irrigation in a controlled way always contributes to the WP, based on an increase in the agronomic performance of the plants (23).
The increase of the whole grains of the treatment A1 with respect to A2 and A3 was 4.93% and 35.65% respectively. These results indicate that water management has a strong component in the industrial quality of the rice grain, as well as the sowing time (21), which apparently, the water deficit at 50 DDT of the transplant, close to the reproductive phase affects the filling of grains Cand therefore, caused the milling process to become bankrupt. Added to this, the percentages of relative humidity were the highest (79 and 83%, June and July, respectively) during the grain filling and maturation period, values that could raise the moisture content in the grain and contribute to the fissure of it. In this regard, the author in a previous study on sowing time, with the INCA LP-4 rice cultivar, found that the February crops harvested in June and July decreased their industrial quality, due to the flooding of the crop and a high percentage relative humidity in the grain maturation phase (21).
When evaluating the water productivity (WP), from the yields, it was found that the WP was higher in the plot in which the water sheet was suspended at 30, 40 and 50 DDT (A1, A2 and A3, respectively), while in the control treatment (Inund) it resulted in a lower yield ( Figure 4 ); It is important to highlight that there were differences between the treatments and that the highest values of the reference variable were found when the water was suspended at 30 DDT.
CONCLUSIONS
- The suspension of the water sheet increased the agricultural yield between 16 and 32% with respect to the flooded control and the industrial one was 67%, with 58% of whole grains when the water sheet was suspended at 30 DDT.
- Water savings were achieved by suspending the water sheet of approximately 1 931.4 m 3 ha -1 in rice cultivation using transplant sowing technology, with respect to flooded treatment throughout its cycle (7 321.20 m 3 ha -1 ).
- The water saved could increase the area under irrigation by 11.19%.
- The suspension of the water sheet at 30 and 40 DDT allowed an irrigation water productivity greater than 1 kg of rice per m 3 of water and it is proposed to suspend the permanent watering at 30 DDT, for a period of 15 days. in which the water sheet is replenished until 15 days before the grain harvest.
