 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 nutrient availability in the soil related to growth, yield and quality characters in garlic. Also to study the effect of sources and levels of silicon on total up take of NPK and Silicon.
Fifteen treatment combinations formed by three sources of silicon fertilizers (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 nutrient availability, the source A2 (CS) recorded significantly highest N, P, K and Si at harvest while in case of levels (B5) application of Si @ 250 kg ha-1 recorded significantly highest N, P, K and Si.
The interaction effect of sources and levels of silicon on available nitrogen and potassium in soil at harvest was nonsignificant, however in phosphorus and silicon it was significant.
The available NPK and silicon in soil was significantly increased with treated over control.

Keywords: Diatomaceous earth, Calcium silicate, Bagasse ash, Silicon
