Determinación de los períodos global y crítico de competencia de las malezas con arroz (Oryza sativa L. Inti) de transplante.

This research work was developed at Lambayeque, Peril. The main aims were to determine weed population, to study their effects on the yield components and to determine the global and critical competition period during sowing and transplantation. Nine treatments were evaluated (10, 20, 30, 40, 50,...
