Response of distinct levels of Phosphorus, Zinc fertilization and Mycorrhizae on Capsicum (Capsicum annuum L.) in protected conditions

Abstract

The present investigation was carried out to analyze the response of distinct levels of Phosphorus, Zinc and Mycorrhizae on capsicum crop during the year 2016. For this, a pot experiment was conducted in the net house of Department of Soil Science and water Management, Dr Y S Parmar University of Horticulture and Forestry Nauni, Solan (Himachal Pradesh). The treatment combination consists of 24 treatments comprising 4 levels of phosphorus: Pa- 0, Pb-237.5 kg ha-1 SSP, Pc-355.5 kg ha-1 SSP and Pd-475 kg ha-1 SSP, 3 levels of Zinc: Zna-5 kg ha-1 ZnSO4, Znb-7.5 kg ha-1 ZnSO4, Znc-10 kg ha-1 ZnSO4 2 levels of mycorrhizal inoculation: Ia-0 and Ib-15 g per pot. The results concluded that plant parameters like root length, plant height and total uptake by the plant increases as level of phosphorus, zinc and mycorrhizae increases. It also concluded that mycorrhizal inoculation resulted in increased plant growth and total nutrient uptake by alleviating Phosphorus or Zinc deficiency.
