Growth and nutrient uptake of black pepper (Piper nigrum L.) varieties in nursery as influenced by the application of Pseudomonas fluorescens and Trichoderma harzianum

Abstract

An experiment was conducted at Indian Institute of Spices Research, Calicut during the months of June to September 2003 to find out the effect of Trichoderma harzianum and Pseudomonas fluorescens on growth and nutrient uptake of black pepper varieties in greenhouse conditions. Observations on plant growth parameters were taken three months after raising the rooted cuttings in polythene bags. Maximum biomass production and uptake of nutrients nitrogen and phosphorous was recordcd by the treatments where combined application of Pseudomonas fluorescens (IISR 6) and Trichoderma harzianum (p 26) were carried out. Among the varieties, maximum biomass production and nutrient uptake was observed in Panniyur3.
