Nitrogen fertilization in super-early cycle common bean using new sources of urea. Author(s): BRAZ, A. J. B. P.; FERREIRA, C. J. B.; SILVEIRA, P. M. da; SIMON, G. A.; ASSIS, R. L. de; BRAZ, G. B. P.; MEDEIROS, R. V. The efficiency of new fertilizers as a nitrogen source in super-early cycle common bean cultivars still needs to be better known. The objective was to quantify the effect of new sources and time of ap... ... Repository: BDPA Publication year: 2018
Nitrogen fertilization in consecutive cycles and its impact on high-density peach crops. Author(s): FERREIRA, L. V.; PICOLOTTO, L.; PEREIRA, I. dos S.; SCHMITZ, J. D.; ANTUNES, L. E. C. The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown... ...
