Evaluación de alternativas biominerales en el cultivo de arroz riego en Montería, Córdoba.

Fertilization is one of the determining factors for good development of rice cultivation. Chemical synthesis fertilizers cause environmental impacts on agro ecosystems. Slow release technology seeks to increase the efficiency of applied nitrogen, lengthening its action over time and avoiding losses such as leaching and volatilization. This research was carried out with the purpose of evaluating the effect of different biomineral fertilizers on rice cultivation under irrigated conditions, in Montería - Córdoba. A randomized complete block design (DBCA) was used, with 6 treatments (5 Permaxion fertilizers and the commercial control) and 4 repetitions in 36 m² plots. The variable levels of Spad, yield components (number of tillers per m²; number of panicles per m²; fullness per panicle; vane; weight of 1000 grains; yield; harvest index, and milling quality) were measured. analyzed with the Infostat Version 2019p program. Significant statistical differences were recorded in the levels of Spad, yield, pile index (%) and broken grain (%). The Permaxion 31-8-8 and Permaxion veranero treatments recorded the best. levels of Spad. Permaxión 31-8-8 achieved the best yield with 6426 Kg/ha, while the control presented 5228 kg/ha. The best pile index and % of broken grains were recorded by the Permaxion 31-8-8 fertilizer. with 54 and 25.3% respectively. Permaxion fertilizers supply nutrients to the rice plant in a controlled manner, achieving balance, expression of maximum genetic potential and sustainability of the crop. [ABSTRACT FROM AUTHOR]
