Evaluation of various doses of N, P, K and combination with organic manure on yield and growth of wheat (Triticum aestivum L) in western Uttarakhand

Abstract

Wheat is rabi crop and is a staple food followed byrice in India, the present studywasevaluated on effect of various doses of N, P and K along with combination of organic manuresviz., compost andvermicompost on wheat (Triticum aestivum Linn.) at RCP PG college, Roorkee, Uttarakhand in the rabi season during2023-24. Thisinvestigation was carriedwithseventreatments viz.,T1100percent RDFof N, P and K, T2(75% RDF and 25% Compost), T3(50% RDF and 50% compost), T4(25% RDF and 75% compost), T5(100% compost), T6(100% vermicompost) and T7(control). The treatments were replicated thrice. The result revealed that among all the treatments T3showed the best result with high initial plant population (56.33 per m2 area) 20 DAS followed by T1with 52.00 plants/ square meter. Whereas numberof tillers per plant wasrecordedhighestinthetreatment T3onlywith 5.22.Theeffect of vermicompost and compost was also observed satisfactory and was sarcastically at par with treatment T2. Plant height was found highest intreatment T3with 52.89 cm followed byT2(50. 56 cm). Yield parameters such as number of spike, wheatspikelength, number of grains/spike andtest weight wererecordedandfound maximumin treatment T3, drymatter accumulation (g/m2) and biological yield was also highest in treatmentT3with 12.07 t/ h. Grain yield per ton per hectare was recorded maximum in treatment T3(50% RDF + 50% compost) with 5.67tonn/hac. Cost benefit ratiowas calculated andobtained highest intreatment T3with1: 1.64and followed byT1(1:1.37).
