Biomass Yields of kenaf in Europe: Effect of site, year and cultural practices on yields

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

This research work aimed to investigate the effect of site, year and cultural practices (varieties, plant densities, sowing dates, and irrigation and fertilization rates) on kenaf yields. This research work was a part of the BIOKENAF project. It was found that the dry stem yields (t/ha) varied among the cultivations sites, depending on the specific climatic conditions of each site. It should be pointed out that the highest yields were recorded in Spain (28 t/ha) and the loest ones in Portugal (3.4 t/ha). Regarding the tested factors it can be concluded that after three experimentation (2003-5) that higher yields were obtained when the sowing date is between end of April to middle of May, when the plant density is high (20-40 plants/m2), when the cultivated variety is late-maturity and when water for irrigation was available (300-400 mm of water). The nitrogen fertilization did not find to play an important role in the biomass yields. It can be only be said that in some sites it was found that when the nitrogen fertilization wa sincreasing the yields were also increasing but only in very few cases this increase was statistical significant.
