Effect of solarization on nutrient availability, enzyme activity and growth of pomegranate (Punica granatum) air-layered on various potting mixtures

摘要

Pomegranate air layers are generally raised on potting mixture consisting of soil, sand and FYM/vermicompost in the nursery. Increasing concern over the impact of chemical fertilizers and pesticides on the environment for raising disease-free vigorousplanting materials necessitate the exploitation of renewable solar energy for disinfecting growth medium and at the same time its enrichment with respect to plant nutrients. Solarization of components in the potting mixture (soil: sand: farmyard manure,
