Yield, morphological and physiological comparative aspects in Ocimum Basilicum L. under different fertilization types

Abstract

The aim of this paper is the comparative evaluation of various types of fertilizers on yield and some physiological parameters of basil plants, cultivated by direct seeding in the field, without irrigation, under the experimental conditions from V. Adamachi farm of U.S.A.M.V. Iaşi. The applied fertilizers were: organic (Orgevit - 600 kg/ha), chemical (N: P: K 20:20:20 - 300 kg/ha), microbial (Mycoseed - 30 kg/ha) and municipal sludge in two doses (40 t/ha and 20 t/ha). Regarding the production of fresh herba, chemical and microbial fertilization led to the highest values, increased with 38% and 19% respectively compared to controls. Similarly, dry mass production increased under the same types of fertilization by 34% and 28% respectively. The number of lateral stems also increased in plants fertilized with municipal sludge and microorganisms. In terms of assimilatory pigments content, higher than the control values were recorded with sludge (40 t/ha), organic and chemical fertilization. In conclusion, fertilization with microorganisms and municipal sludge can be a viable and sustainable alternative to chemical fertilizers for the cultivation of basil.
