Effect of Various Mycorrhizae-based Products on Growth and Phytotoxicity Characteristics of Potato (Solanum tuberosum L.) cv. Kufri Sindhuri

Abstract

Mycorrhiza refers to the symbiotic association between fungus and plant root. The arbuscular mycorrhizal symbiosis auguments the growth and plant resistance to biotic and abiotic stresses by enhancement through certain nutritional, biochemical, physiological as well as morphological plant responses thus it has gained a high degree of impetus in recent years. In this context, a study was conducted to study the effect of various mycorrhizae based products on growth and phytotoxicity characteristics of potato (Solanum tuberosum L.) cv. Kufri Sindhuri during Rabi 2016-17 at Vegetable research farm, Department of Horticulture, Institute of Agricultural Sciences, BHU, Varanasi to evaluate the effect of various mycorrhizal products at different concentrations on growth and phytotoxicity characteristic of potato. The field experiment consisted of 8 treatments involving different mycorrhizal products including the control (untreated). From the experiment it was found that soil application with Myc100 at 250 g/ha (treatment T2) had very promising results for the investigated characters viz., number of leaves/hill (62.20), Plant height at 30 Days after planting (65.40 cm), Plant height at 60 Days after planting (98.24 cm) as compared to other treatment followed by T8- soil application with Bolt Gr at 10 kg/ha. The maximum number of haulms per plant was observed in treatment T6- soil application with Rhizomyxo 100 at 250 g/ha (4.35). No symptoms of phytotoxicity was observed in all treatments during crop growth.
