Abstract:
A field experiment was conducted during the Kharif season in 2018 on loamy sand soil at the OPJS University, Churu (Rajasthan). To study the influence of plant growth regulators (PGRs) and zinc fertilization on the growth and yield attribute of pearl millet comprised of three PGRs (1000 ppm triacontanol, 50 ppm naphthalene acetic acid (NAA) including water sprayed (control) with four levels of zinc (0, 2, 4 and 6 kg ha-¹). The experiment was conducted in a factorial randomized block design with two factors and replicated thrice. The results revealed that foliar application of 20 and 40 DAS in pearl millet of PGRs and zinc significantly was recorded an increase in chlorophyll value, the total number of tillers/ plants, effective tillers/ plant, ear length, number of grains/ ears, grain weight panicle-¹, test weight, grain yield, stover yield, biological yield, and harvest index over water sprayed (control). Triacontanol and NAA gave significantly over control in growth and yield attributed. Significantly increased with zinc fertilization @ 4 kg Zn/ha over control, which was remained at par with 6 kg Zn/ha in growth and yield attributed.
