Impact of InM practices on vegetative growth and flowering of hybrid gerbera (Gerbera jamesoneii B.) cv. Shimmer in open field condition

The present investigation on Impact of InM practices on growth and flowering of gerbera was carried out in premises of Biotechnology cum Tissue Culture Centre OUAT Bhubaneswar during nov. to Oct. 2015–16 and 2016–17. The objective of the study was to develop an InM model for cut flower production of gerbera in open field condition. eight fertilization treatment combinations were used consisting of 100% RDF, Vermicompost, 75% RDF, PSB, Azospirillum, Azotobacter, and foliar application of macro and micro elements. The result revealed that application of 75% RDF (15: 10: 30 g nPK/10 plants) + Vermicompost+ (25 g/10 plants) + Azospirillum/Azotobacter (20 g/10 plants)+ PSB(20 g/10 plants)+ macro and micro element spray increased all of vegetative parameters of gerbera. In flowering parameter, number of flower/m²/year were maximum in the same treatment. It can be concluded that reducing level of chemical fertiliser to 75% RDF along with application of different organic source of nutrient can improve flower yield of gerbera in open field condition.
