The entire world situation and good charges print encouraging potential clients for the sunflower revival in the subsequent campaign. From north to south, the representatives went by way of the cycle of interviews of the Aapresid Agenda and shared the administration keys for a prosperous harvest.
Adjustment of density and planting date
The NEA, with a very long record of sunflowers, opens each individual campaign from mid-July to the conclude of August. The most important conditioning component for planting is humidity, mentioned councilor and producer Martín Canteros, a member of Aapresid’s Sáenz Peña Regional. “You should have at minimum 130 mm in the profile to aspire to a density in between 23 and 29,000 crops / ha”.
Not like the north, the south of Bs. As. Has integrated sunflower into its plantations a lot more not too long ago, as a system to diversify and complicate lifetime for hardy weeds like ryegrass, said Guillermo Irastorza, producer from Bahía Blanca. In this spot it is essential to oil the handling to beat dry and windy summers and coarseness to 30-50 cm. This is achieved by altering the density and the day: “between 20 and 23,000 plants planted as shortly as probable, so that flowering avoids the January drinking water deficit,” he specified.
Toward the west of the region (southeast of San Luis, south of Córdoba, northeast of La Pampa and northwest of Bs. As.), The sandy soils and the affect of the drinking water desk do not stop to the sunflower to find its niche with direct sowing. Here the specialist and producer Guillermo Rivetti proposes from 47 to 55,000 vegetation / ha, planted in late September-early Oct. The place the strain of resistant purple weeds is higher, it is a good idea to do it setting up from the next fifty percent of Oct, soon after acquiring utilized the pre-emergents, to velocity up the closure of the furrow and favor the opposition of the crop.
Fertilization and command of biotic adversities
To ensure a very good population of the plants, fertilization is a further basic place, primarily in previous farms, influenced by previous tillage and with undernourished land. There it is crucial to use phosphorus and nitrogen starters, such as biofertilizers to begin the crop on the ideal foot. In the West, doses of 100-120 N models applied in vegetative circumstances have demonstrated superior success for anticipated yields of at the very least 30 qq.
Though in typical it is a really nutritious crop, late plantings in the north can be attacked by caterpillars, mostly crochet. On the other hand, early sunflowers have better organic regulate as there is a lot less need to have for apps, with the exception of unique cases these types of as the south of Bs As the place Phomopsis has place a pressure on the wheel in the latest strategies.
The sunflower in rotation
In the north, this crop generally happens to soy and is adopted by herbs these types of as corn or sorghum. Alternatively, the area is experimenting with the manufacturing of provider crops (SC) immediately after sunflower, on your own vetch, blended with wheat or Aeschynomene sp, a summer season legume that matches quite properly in between successive sunflowers.
Thanks to its hardiness and drought tolerance, sunflower has aggressive positive aspects in the restrictive environments of the sandy west, in which soybeans wrestle to be successful. On the other hand, it is gaining surface in cattle integration proposals, as it releases the batch early (late February-mid-March) so that a CS afterwards matches as a vetch.
Genetics that make the variance
Clearfield hybrids stand out in just the germplasm presenting as they make it possible for for far more productive administration of weeds such as grasses by allowing the use of residual herbicides at planting. There are also products fewer vulnerable to lodging and with chapters inclined to maturity, which facilitate drying and control to stay clear of hurt from pigeons. For their section, the “black hybrids” give a bonus on oil that can be discounted up to 20% of the cost.
The differential bonus is an incentive to deal with the expenditures of chartering and transportation to port, a principle that usually takes 18-20% of the price of the sunflower in the NEA. Even so, the selling price outlook is incredibly superior and aids in the final decision generating system. “If the seed source is ensured and the rains accompany it, it will be the best campaign for the sunflower grower,” inspired the producers.
The “girasole tour” was element of it Aapresid agendathe digital appointment where by specialists, producers and providers satisfy to provide the technical details that the agricultural producer demands, when he requires it.
Each and every version airs from Monday to Friday at 7.00 pm from the Aapresid Digital Group streaming platform, and on Saturdays at 7.30 pm in compact structure on Somos Rosario (channel 7 of the analogue and electronic network Rosario and channel 520 by Stream Box and Movement Application, in the rest of the state).
