Aim: To study response of various nitrogen levels and plant growth regulator on production and productivity of wheat crop (Triticum aestivum L.)

Study Design: The field experiment was conducted in randomized block design (RBD).

Place and Duration of Study: A field experiment was carried out in the Agriculture Farm, School of Agriculture, Abhilashi University Chail chowk Mandi (H.P.) during Rabi Season 2022-2023.

Methodology: Seven treatments namely T1- Control (No Nitrogen and no growth regulator spray), T2- 50% RDN (N60, P60, K40), T3- 75% RDN (N90, P60, K40), T4- 100% RDN (N120, P60, K40), T5- 125% RDN (N150, P60, K40), T6- 125% RDN (N150, P60, K40) with growth regulator (Chlormequat chloride 0.2%), T7- 150% RDN (N180, P60, K40) with growth regulator (Chlormequat chloride 0.2%).

Results: The scrutiny of data clearly reveals that the application of 150% RDN (N180, P60, K40) with growth regulator (Chlormequat chloride 0.2%) (T7) gave significantly the highest value of growth parameter, yield attributes and yields, which is at par with T6 [125% RDN (N150, P60, K40) with growth regulator (Chlormequat chloride 0.2%)]. But the highest plant height was recorded under treatment (T5) which is 125 % RDN (N150, P60, K40) because under treatment T7 & T6 application of CCC causes the shortening of plant height. Nutrients were added according to treatment doses.

Conclusion: On the basis of one season study among various treatments, treatment T7 -150% RDN (N180, P60, k40) with growth regulator is best for enhancing the yield and productivity of wheat crop.

Keywords: Nitrogen, chlormequat chloride, wheat, RDN, PGR
