Effect of wheat [Treticum aestivum (L.)] varieties under fertility levels and seed rates on physiological parameter, nutrient content and uptake of crop plant

A field experiment was conducted during 2013-14 and 2014-15 at research farm, RVSKVV, College of Agriculture, Gwalior, Madhya Pradesh. The experiment involve thirty treatment combinations consisting of two varieties viz. V1: RVW 4106 and V2: MP 4010 as well as three seed rates viz. S1: 100 kg/ha; S2: 125 kg/ha and S3: 150 kg/ha and five fertility levels i.e. F1: 50% RDF + 10 tonnes FYM/, F2: 75% RDF + 5 tonnes FYM/ha, F3: 100% RDF, F4: 125% RDF and F5: 150% RDF in factorial R.B.D with 3 replications. The result revealed that the maximum physiological parameter and N, P and K content and uptake were recorded under the variety MP 4010 as compared to RVW 4106. Seed rate 150 kg ha-1 gave significantly highest NPK uptake as compared to 125 and 100 seed kg ha-1 whereas maximum physiological parameter were non-significant under seed rates levels. Fertility level, 75% RDF + 5 tonnes FYM ha-1 gave significantly higher content and uptake of N, P and K nutrient by crop as well as maximum physiological parameter.
