dc.description.abstractThe present investigation entitled „Effect of planting time and harvesting schedule on productivity and quality of Japanese mint varieties‟ was carried out at Research farm, School of Organic Farming, Punjab Agricultural University, Ludhiana during spring season of 2023. The experiment was laid out in split plot design with three replications, keeping combinations of three planting times (15th January, 30th January and 15th February) and three varieties (CIM Unnati, CIM Kranti and Golden (Local)) in main plots and two harvesting schedules (130 DAP and 145 DAP) in sub plots. The soil of the experimental site was loamy sand in texture with slightly alkaline soil reaction (pH- 7.85) and normal electrical conductivity (0.27 dS m1), low in organic carbon (0.34%) and available nitrogen (115.4 kg ha-1), medium in available phosphorus (18.2 kg ha-1) and potassium (160.5 kg ha-1). The results showed that Japanese mint planted on 15th February recorded significantly higher growth parameters, fresh herb (267.4 q ha-1), dry herb (79.1 q ha-1) and oil yield (176 l ha-1) as compared to 15th January planted crop but at par with the crop planted on 30th January. The variety „Cim Kranti‟ recorded significantly higher plant height (93.7 cm), stool population (63.6) and dry matter accumulation (856.2 g m-2) followed „CIM Unnati‟ and „Golden (Local)‟, consequently resulting in significantly higher fresh herb yield (265.6 q ha-1) and dry herb yield (77.7 q ha-1) over „Golden (Local)‟ but at par with „CIM Unnati‟. However, „CIM Unnati‟ variety produced significantly higher oil yield (200.9 l ha-1) with increase of 66.7% and 20.3% over the „Golden (Local)‟ and „CIM Kranti‟, respectively. Moreover, significantly higher fresh herb yield (264.7 q ha-1), dry herb yield (77.1 q ha-1) and oil yield (174.2 l ha-1) were recorded with harvesting the crop at 145 DAP, while significant reduction to the tune of 17.6%, 17.4% and 15.1% in fresh herb, dry herb and oil yield, respectively was recorded with early harvesting at 130 DAP.
