Biomass Accumulation and Technical and Economic Efficiency of Potassium Sources Applied via Fertigation to Corn
نویسندگان
چکیده
To achieve high corn yield, optimal amounts of nutrients that can be extracted by the crop must supplied at adequate proportions. Vinasse from sugarcane ethanol production applied as a soil fertilizer to crops in plants. In this context, present study compared effects mineral potassium fertilization with chloride and organic concentrated vinasse on dry matter grain yield explored technical economic efficiency these sources. The experiment was carried out experimental station Federal Institute Goiano, Rio Verde Campus, Brazil. followed randomized block design 2 × 4 factorial scheme, three replicates. treatments comprised two sources potassium, namely chloride, four doses representing 0%, 50%, 100%, 200% recommended rate for corn. accumulation throughout cycle, components harvest, were measured. Neither dose nor its source affected leaf, stem, aboveground harvest. Regardless source, 100% produced higher cob mass, mass per ear, number bags 60 kg ha−1 hectare, harvest index. agronomic 68.5% recommendation, showing enough potential an crop.

Fertigation and Conventional Potassium Application to Field Grown Potato in Lebanon: Perspective to Enhance Efficiency
In Lebanon, potato occupies a surface of 14,800 ha corresponding to 17% of the irrigated land. The Bekaa valley is the largest production area in the country, with more than 67% of total potato production located on prime land. This crop is generally fertilized by soil application and irrigated by sprinklers with rare implementation of drip systems. Spring and summer potatoes depend entirely on...
متن کاملPotassium chloride in fertigation
The rapid proliferation of fertigation in modern agriculture has brought about a growing demand for factory mixed fertilizer solutions, as well as wide-scale dissolution of solid fertilizers by farmers in the field. Rules of chemistry and physics control the rate of dissolution and, hence, the nutrient content in the fertilizer solution. Potassium chloride (KCl) is the cheapest potassium-contai...
