摘要

Foliar fertilization provides nutrients to plants by mist in a straight line onto foliage and flora. These fertilizers provide important nutrients for plant development. Therefore foliar fertilization of macro and micro nutrients subjective the vegetative growth and flowering superiority of gerbera. Current study was planned to observe the effect of foliar purpose of macro (NPK) and micro nutrients (Zn, B, Fe and Mn) on gerbera growth and flowering production. The fertilizer solution of macro nutrients containing 1 g, 1.5 g and 2 g of nitrogen, potassium and phosphorus, respectively and micro power contain 5000+or-200, 4000+or-200 and 5000+or-200 mg/100 ml solution of Zn, B, Fe and Mn. Different concentration of macro nutrients i.e. 12.5 ml+987.5 ml water, 18.75 ml+981.25 ml water and 25 ml+975 ml water taken and sprayed fifteen days intervals on potted gerbera. Spray of micro power (solution of different micronutrients) was also being applied at constant rate of 5 ml/1000 ml solution of water. Plant height, number of branches per plant, length of branches per plant, number of leave per plant, leaf area, stock length, days to first flower emergence, flower diameter and flower quality increased with increasing fertilization level and began to turn down when fertilization level exceed beyond the above given levels of macro and micro nutrients. Foliar fertilization influenced the days to first flower emergence as compared to control where no foliar spray of macro and micro nutrients was applied. It took 85.55 days in T3 treatment as compared to control i.e. 105.55 when macro nutrients spray applied and in case of micro nutrients it took 81.88 days in flower emergence as compared to control i.e 100.88.
