Response of rhizomatic parameters of Alstroemeria to organic and inorganic fertilizers under protected conditions

Abstract

A study entitled response of Alstroemeria to organic and inorganic fertilizers under protected conditions was conducted with three levels of nitrogen viz 150, 200 and 250 ppm. Phosphorus two levels viz 100 and 150 kg/ha, while as with three levels of organic manure viz. vermicompost 2.5 t/ha, FYM 5t/ha and sheep manure 5 t/ha respectively. The results revealed that nitrogen at 250 ppm/15 days interval obtained maximum weight of rhizomes (300.56 g), maximum number of rhizomes developed/planted rhizome (8.88) and maximum propagation coefficient (888.89) which was significantly superior over all other treatments. Phosphorus at 150 kg/ha recorded significantly highest number of rhizomes developed per planted rhizome (870.37). Vermicompost recorded significantly maximum number of rhizomes developed/ planted rhizome (331.11 g) and maximum propagation coefficient (961.11). The interaction effects between (N and P), (N and O), (P and O) and (N, P and O) were however non-significant.
