Effect of Sulphur and Micronutrients on the Yield and Quality of Garlic (Allium sativum L)

Abstract

The field experiment was conducted at the Horticulture Farm, Sri Karan Narendra College of Agriculture, Jobner, Jaipur (Rajasthan) to find out the effect of sulphur and micronutrients on yield and quality of garlic during Rabi seasons 2019-20 and 2020-21. The experiment was carried out in factorial randomized block design with three replications and twenty treatment combinations with four levels of sulphur (S0-control, S1-sulphur 20 kg/ha, S2-sulphur 40 kg/ha and S3-sulphur 60 kg/ha) and five levels of micronutrients (M0-Control, M1-zinc sulphate @ 0.6%, M2-ferrous sulphate @ 0.2%, M3-borax @ 0.5 and M4-Ammonium molybdate @ 0.5%). The sulphur was applied as soil application just before sowing and micronutrients (Zn, B, Fe and Mo) as foliar spray at 40 days after sowing. Recommended dose of inorganic fertilizers applied uniformly in whole experimental area. The results of the study have clearly indicated that among sulphur levels, application of sulphur 60 kg/ha significantly improved yield and quality parameters viz., average weight of clove, average weight of bulb, bulb yield per plot, per hectare, nitrogen content, phosphorus content, potassium content and sulphur content in bulb enhanced significantly by application of sulphur 60 kg/ha (S3) in both the years as well as in pooled analysis. Although, sulphur application at 40 kg/ha along with foliar application of zinc at 0.6 % was found at par to it. Similarly, among micronutrients foliar application of zinc sulphate @ 0.6% significantly influenced all the yield and quality parameters viz., average weight of clove, average weight of bulb, bulb yield/plot, bulb yield/hectare, nitrogen content, phosphorus content, potassium content and sulphur content in bulb of garlic in both the years as well as in pooled analysis.
