Effect of foliar feeding of micronutrients on growth and yield of cauliflower (Brassica oleraceae var. botrytis L.) cv. Ragini under net tunnel

Abstract

The present experiment was conducted at Centre of Excellence on Protected cultivation & Precision Farming at Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh under net tunnel with eight treatment and three replications in Randomized Block Design (RBD) the treatment consisted four different micronutrient (B, Mo, Zn, S) and its combination with different concentrations and recommended dose of fertilizer viz. T0: RDF + Control (water spray), T1: RDF+ Boric acid (H3BO3) @0.2%, T2: RDF+ Ammonium molybdate ((NH4)2MoO4) @0.1%, T3: RDF+ [email protected]%, T4: RDF+ [email protected]%, T5: RDF+ Boric acid @0.2%+Ammonium molybdate ((NH4)2MoO4) @0.1%, T6 : RDF +Boric acid(H3BO3) @ 0.2% + Ammonium molybdate ((NH4)2MoO4) @ 0.1%+ ZnSO4 @ 0.5% and T7: RDF + Boric acid (H3BO3) @0.2%+ Ammonium molybdate ((NH4)2MoO4) @ 0.1% + ZnSO4@ 0.5% + MnSO4 @0.5%. Data were analyzed to work out the growth and yield parameters. Result revealed that T7: RDF +Boric acid @ 0.2%+ Ammonium molybdate@ 0.1%+Zinc sulphate @ 0.5%+ Manganese sulphate @ 0.5% was exhibited early initiation and maturity of curd. Highest curd yield 34.98 t/ha was produced in T7: RDF +Boric acid @ 0.2%+ Ammonium molybdate@ 0.1% + Manganese sulphate@ 0.5%+Zinc sulphate@ 0.5% followed by T6: RDF + Ammonium molybdate@ 0.1%+ Boric acid @ 0.2% + Zinc sulphate@ 0.5% which was 33.97 t/h.
