Growth and productivity of periwinkle [Catharanthus roesus (L.) G. Don] in relation to integrated nutrient management

摘要

An experiment was carried out to study the effect of integrated nutrients application on growth and productivit of Periwinkle, The experiment was conducted using RBD and each treatments with replicates (X^). The growth an productivity parameters weresignificantly influenced by different nutrient management packages. The treatment Tg [10 tonnes FYM/ha + NPK (80 : 30 : 50) kg/ha] followed by T,2 [Bone meal + Neem cake (each @ 150 k{ ha) + NPK (80 : 30 : 50) kg/ha] were found more effective for increasing plant growth and productivity ol Periwinkle. The highest yield of plant biomass was recorded with T,2 followed by Tj^ [ZnS044 @ 25kg/ha +(80 : 30 : 50) kg/ha] during two subsequent experimental years. Results are discussed in detail in present paper,[Medicinal Plants 2015; 7(2) : 114-119]
