Effect of Plant Growth Regulators and Bio-Fertilizer on Growth and Quality of Fenugreek (Trigonella foenum-graecum L.)

The present investigation entitled “Effect of plant growth regulators and bio-fertilizer on growth and quality of fenugreek (Trigonella foenum-graecum L.)” was carried out at the Experimental field, College of Agriculture, RVSKVV, Gwalior during 2020-21 under agro-climatic and soil conditions of Northern Madhya Pradesh. The experiment was laid out in Randomized Block Design (RBD) with three replications. Each replication consists of ten treatments of biofertilizers viz., Rhizobium, Phosphate solubilizing bacteria (PSB) and Potassium solubilizing bacteria (KSB) and plant growth regulators viz., Gibberellic acid (GA3) and Naphthalene acetic acid (NAA). All the treatments were randomized separately in each replication. Result showed that the different biofertilizers (i.e. Rhizobium, PSB and KSB) and plant growth regulators (i.e. GA3 and NAA) treatments significantly influenced the growth and quality parameters of fenugreek. Treatment T4 (Rhizobium + NAA) gave the maximum growth, it was found best treatment combination as compared to all other treatment combinations of biofertilizers and PGRs, while the minimum growth, yield and economical parameters were recorded in treatment T1 (Control).
