Cotton: the brand new white gold of San Luis

In Argentina, cotton has an extended historical past and has been a basic piece within the nation’s financial development (Chacra Journal)

Cotton, identified for its resistance to local weather modifications and its adaptability to dry and arid situations, is grown in additional than 75 international locations and occupies simply 2.1% of the world’s arable land. Nevertheless, its manufacturing meets 27% of world textile wants.

In a nook of the northeast of San Luis, the Conlara Valley, a gaggle of researchers from INTA and the Nationwide College of San Luis (UNSL) has discovered a promising resolution to diversify the agricultural rotation of the realm: the cultivation of “gold white”. This discovering could possibly be the important thing to boosting the native economic system and offering new alternatives for farmers within the area.

This crop has a singular efficiency, since nearly nothing of the plant is wasted: it’s used within the textile trade, livestock farming, the manufacture of edible oils, cosmetics and biofuels. Its major product, fiber, is crucial pure textile on the planet.

In Argentina, cotton has an extended historical past and has been a basic piece within the nation’s financial development. Over the last marketing campaign, whole manufacturing reached a formidable 896,464 tons, of which roughly 269,000 tons have been fiber.

Historically, cotton cultivation in Argentina has been concentrated within the provinces of Chaco, Santiago del Estero and Santa Fe. However now, due to rising demand and analysis carried out in San Luis, this space can be rising as a brand new producing area.

The examine carried out within the Conlara Valley through the 2022/23 agricultural marketing campaign, led by Héctor Andrada, researcher on the INTA Quines Extension Company, and his workforce, evaluated three styles of cotton: Guazuncho 4 INTA BGRR, Porá 3 INTA BGRR and Guaraní INTA BGRR, all developed by INTA.

Within the “Don Andrés” demonstration institution, plots have been planted utilizing a randomized full block design with 4 repetitions for every therapy. Sowing was carried out in a plot of corn because the predecessor crop, with a density of 10 seeds per linear meter.

The trial, carried out in dryland situations, was stored freed from weeds and bugs all through the cycle. To regulate vegetative development and procure extra compact vegetation, 4 purposes of development regulator have been made through the reproductive stage. This method helped obtain a larger variety of ripe capsules on the time of harvest.

Belén Bravo, researcher of the Agriculture Group of the San Luis Experimental Station of INTA, highlighted the outcomes obtained: “Based mostly on the harvested materials, the Guaraní BGRR cultivar confirmed a median yield of 1990.50 kg/ha (gross yield) and 1353. 50 kg/ha (fiber and seed), with out important variations with respect to the opposite varieties evaluated.”

Marcelo Bongiovanni, analysis professor at UNSL, summarized the findings: “The outcomes of this primary expertise exhibit that cotton cultivation has the potential for adaptation and manufacturing within the edapho-climatic situations of the realm.” As well as, he identified that this examine represents a chance to advertise cultivation within the area utilizing short-cycle varieties, which mix some great benefits of biotechnology with the attributes of the germplasm developed by INTA.

Incorporating cotton into the Conlara Valley’s conventional agricultural rotation could possibly be a recreation changer for native farmers. Not solely might it enhance the profitability of its land, but in addition promote extra sustainable and socially accountable improvement, due to the intensive labor that cotton cultivation requires.

The subsequent step is the continuity of those experiences to generate further knowledge on the conduct of the crop in successive agricultural campaigns. Gathering extra data will permit changes to agricultural practices and maximizing cotton yields on this new rising area.

Cotton isn’t solely a hardy and versatile plant, but in addition a golden alternative for Northeast St. Louis. With the help of science and expertise, “white gold” might change into a brand new supply of prosperity for the Conlara Valley, opening a brand new chapter within the area’s agricultural historical past.
