ABSTRACT

The present investigation was under taken on garlic (Allium sativum L.) cv. Phule Nilima to study the effect of silicon at All India Coordinated Research Project on Vegetable Crops, Department of Horticulture, MPKV, Rahuri, Dist. Ahmednagar in rabi season of 2017-18, by using different sources and levels of silicon on chemical properties of soil and silicon availability in the soil related to growth, yield and quality characters in garlic. Fifteen treatment combinations formed by three sources of fertilizer silicon (viz., diatomaceous earth, calcium silicate and bagasse ash) with five levels of silicon (viz., 0,100,150, 200 and 250 kg ha-1) and one absolute control, were tried and each replicated three times. The basal dose of fertilizer 100 N, 50 P2O5 and 50 K2O kg ha-1was applied before planting. In case of effect of sources and levels of silicon on chemical properties of soil, source A1 (DE) recorded significantly highest OC, while source A2 (CS) recorded significantly highest pH and EC (dsm-1) while in case of levels (B5) application of Si @ 250 kg ha-1 recorded significantly highest pH, EC, and OC. The interaction effect of sources and levels of silicon was not significant for all three soil properties under study. The pH, EC and Organic Carbon were significantly increased with treated over control.
