“This method is right here to remain,” says rice producer Luis Valenzuela from the Santa Amelia sector, in San Carlos, when referring to the implementation of the SRI (System of Rice Intensification), which is being carried out by the INIA. as a brand new strategy to produce rice in Chile.
This technique makes use of intermittent irrigation, changing the standard flooding that has characterised this crop, a change that isn’t whimsical, because it responds to the rising lower in water for irrigation, in a lot of the world.
For Valenzuela, the shortage of water is an enormous downside, which is why he follows the irrigation system very intently. “It is extremely pleasant to the setting, with lots of water financial savings, with appreciable financial savings in doses of seeds and fertilizers,” he highlighted, after attending the sector day “Rice and local weather change: INIA’s contribution to the variation of the crop and nationwide meals safety”.
This exercise was inserted within the execution of the analysis challenge “Extra productive and sustainable rice for Latin America”, an initiative that’s promoted by the Regional Fund for Agricultural Expertise (Fontagro) and executed by INIA at the side of FLAR, IICA, and different facilities. of South American analysis.
The sphere day held in San Carlos was attended by fifty producers from the realm, and was attended by the regional director of Indap, Fernanda Azócar, and the regional director of INIA Quilamapu, Javier Chilian, who highlighted the significance of INIA completely generate new types of rice, since its founding in 1964. “Immediately we’d like seeds which are extra proof against local weather change and extra environment friendly in using the little water we’ve got.” He added that the SRI irrigation system is “unthinkable with the varieties from 10 years in the past (…) it might be unattainable, since these varieties weren’t developed for the circumstances we’re in immediately.” On this final side, Javier Chilian indicated that the rice genetic enchancment program “is growing varieties for the contingency of the second.”
Identical efficiency however 50% much less water
Farmer Luis Valenzuela highlighted that with the SRI system the soils are ready to be irrigated intermittently each seven or ten days, relying on what the soil moisture devices point out. He burdened that the brand new system saves 50% of the water circulate that was usually used. “From the 18,000 to twenty,000 cubic meters that we use within the conventional system, we are able to scale back it by half, that’s, from 10,000 to 12,000 cubic meters, which is a superb benefit.”
The producer added that he has been testing for 2 years, steadily rising the variety of hectares allotted to this method, as much as seven hectares this season. Among the many benefits, he additionally highlighted that the appliance of nitrogen, which has an effectivity of 70% in dry soil, whereas in flooded soil it solely reaches 30%, along with the financial savings in merchandise for weed management.
The event of SRI know-how, additionally known as climate-smart rice, is promoted by INIA Quilamapu researcher, Karla Cordero, with the help of the Inter-American Institute for Cooperation on Agriculture (IICA). “This method modifications all administration practices in order that rice will be grown solely with irrigation, which permits us to provide rice that’s extra environmentally pleasant, by utilizing much less water,” says the agronomist, who provides that with the The absence of flooding “methane stops being produced and the manufacturing of nitrous oxide decreases,” each greenhouse gases, which impacts the safety of the setting.
INIA Jasper and Onyx: new varieties
Karla Cordero, who can also be in command of INIA’s rice genetic enchancment program, stated that one other of the related elements of the sector day was the presentation of the brand new varieties that, for now, are within the multiplication stage to turn out to be widespread subsequent time. season. These are Ónix INIA, the primary number of Chilean black rice, and Jaspe FL, a spread obtained from the settlement with the Latin American Fund for Irrigated Rice (FLAR), characterised by excessive precocity within the area, which interprets into better financial savings. of water.
One other space that additionally attracted consideration was the pattern of microorganisms meant to strengthen the rice plant. “It includes the pelletization of rice seed with Endomix INIA merchandise, based mostly on useful fungi Tricoderma and Beauveria.” Karla Cordero defined that this work, promoted along with INIA Quilamapu researcher Lorena Barra, seeks to advertise using bioinputs in rice crops “which can assist the plant in instances of abiotic stress”, a state of affairs that’s each extra frequent because of local weather change.
