ABSTRACT

​

The present field experiment was conducted at Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture, RVSKVV, Mandsaur (MP) during the year 2020-2021 using Randomized Block Design in three replications. The experiment was carried out with various bio-fertilizers (PSB and Azotobacter @ each 5 kg/ha) and different doses of chemical fertilizers (NPK) along with one control.  Result revealed that  treatment T11 -NPK (40:50:40 kg/ha) + FYM (20 t/ha) + PSB+ Azotobacter (each 5 kg/ha) was recorded highest values of plant height (20.97, 101.20 and 114.40 cm plant-1), number of branches at harvest  (26.29 plant-1), fresh weight (8.34, 95.57 and 84.17 g plant-1) and dry weight (1.19, 19.11 and 40.40 g plant-1)  at 40, 80 and 120 days after sowing respectively. However, days to 50% emergence (6.28), days to 50% flowering (61.32) and days to maturity (114.38) were took lowest days with the same treatment. The maximum seed yield (22.06 q ha-1), biological yield (83.59 q ha-1), test weight (1.89 g) and highest harvest index (26.40) in the same treatment as compared to control. Under the economics of the treatment, the highest net return (Rs 70300) and benefit: Cost ratio (1.75) also found with same treatment.
