Irrigation management based on reference evapotranspiration for pre-sprouted pl...
Ohashi,Augusto Yukitaka Pessinatti; Pires,Regina Célia de Matos; Xavier,Mauro Alexandre; Perecin,Dilermando; Silveira,Laís Karina; Petri,Rômulo HenriqueABSTRACT The pre-sprouted sugarcane plantlets (PSP) system aims the production of healthy and vigorous plants in reduced time, reducing the number of stalks needed for planting. Irrigation is used in all PSP system stages and water management plays an important role. Stage 1 acclimation follows the budding stage and lasts for approximately 21 days. At this stage the plantlets are grown within an agricultural gr...
Root growth and distribution in sugarcane cultivars fertigated by a subsurface ...
Ohashi,Augusto Yukitaka Pessinatti; Pires,Regina Célia de Matos; Ribeiro,Rafael Vasconcelos; Silva,André Luiz Barros de OliveiraDespite of the agronomic importance for water management, few studies of sugarcane roots have been performed under field conditions during the crop cycle. The aim of this study was to determine the cumulative root density (LA), root distribution on soil profile and the effective rooting depth (ERD) for three sugarcane cultivars using the minirhizotron method. A field experiment was done with sugarcane cultivars...
