Abstract
A field experiment was conducted at the Agriculture Research Farm, School of Agricultural Sciences and Technology, RIMT University, Mandi Gobindgarh, Punjab during rabi season 2023-24. The experimental field was laid out in a randomized block design (RBD) with 8 treatments and replicated thrice. The treatment combinations are T1- control, T2- 100% Recommended Dose Nitrogen (RDN) and T3- 75% RDN + 5t Farm Yard Manure (FYM) ha-1, T4- 75% RDN + 5t FYM ha-1 + Azotobacter 20 ml ha-1, T5- 75% RDN+ Azotobacter 20 ml ha-1, T6- 50% RDN + 10t FYM ha-1, T7- 50% RDN + 10t FYM ha-1 + Azotobacter 20 ml ha-1, T8- 50% RDN + Azotobacter 20 ml ha-1. The result of present study revealed that the treatment T4 (75% RDN + 5t FYM ha-1+ Azotobacter 20 ml ha-1) has shown significant result on plant population m-2(at harvest) (14.5), plant height (153.2cm), number of branches plant-1 (20.5), chlorophyll content (µmol m-2) (SPAD) (45.10), no. of siliqua plant-1(300.10), no. of seeds siliqua-1 (18.0), siliqua length (cm) (5.90cm), test weight (g) (3.36g), seed yield q ha-1 (22.98 q ha-1), straw yield q ha-1 (56.07 q ha-1), biological yield q ha-1 (79.06 q ha-1) and harvest index (%) (28.80%) were observed.
