Variable rate application of potassium fertilizer for soybean crop growth in a no-till system. Author(s): BERNARDI, A. C. C.; GIMENEZ, L. M.; SILVA, C. A.; MACHADO, P. L. O. A. Variable rate application of fertilizer has the potential to improve nutrient use efficiency, improve economic returns, and reduce negative environmental impacts. The objective of this study was to ev... ... Repository: BDPA Publication year: 2010
Application rate and nozzles associated with droplet electrification affect the spraying quality in common bean. Author(s): MELLO, C. E. L.; CARMO, E. L. do; BRAZ, G. B. P.; PROCOPIO, S. de O.; SIMON, G. A.; SOUZA, M. de F.; ARAÚJO, G. E. S. de; LINS, H. A. Abstract: The objective of this work was to evaluate the application efficiency of different nozzle tips associated with increasing application rates. A field experiment was conducted in a factorial 3... ... Repository: BDPA Publication year: 2024
Mepiquat chloride application on cotton at variable rate. Author(s): MAGALHAES, P. S. G.; QUEIROS, L. R.; GADANHA, C. D. Mepiquat chloride (1.1 - dimethylpiperidinium chloride) are used to control excessive vegetative growth in cotton (Gossypium hirsutum L.) broadcast sprayed by ground or air. As proven by previous rese... ... Repository: BDPA Publication year: 2010
Yield performance of upland rice cultivars at different rates and times of nitrogen Application. Author(s): BARRETO, J. H. B.; SOARES, I.; PEREIRA, J. A.; BEZERRA, A. M. E.; DEUS, J. A. L. de Nitrogen is the most important nutrient for rice (Oryza sativa L) yields. This study aimed to evaluate the response of upland rice cultivars to N rate and application times in a randomized block desig... ... Repository: BDPA Publication year: 2012
Intercropping systems of corn and forage grasses with application of low mesotrione herbicide rates. Author(s): CORREIA, N. M.; LENZA, R. A. do B. ABSTRACT - Sowing forage grass species of the genera Urochloa and Panicum simultaneously with corn can hinder crop grain yield, requiring the application of low herbicide rates for suppressing their g... ...
