Effect of Nitrogen Levels on Growth Performance of Cardamom (Elettaria cardamomum M.) CV. Mudigere-1

The present experiment was carried out during the year 2023-24 at the Nursery No. 4, College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Maharashtra, India. The seven treatments replicated thrice comprising of various nitrogen levels (75, 100, 125, 150, 175 and 200 kg/ha/year) with constant level of phosphorus (75 kg/ha/year) and potassium (200 kg/ha/year) and RDF of Kerala Agriculture University as control were tested under Randomized Block Design. The result obtained from the present experiment revealed that different nitrogen levels along with the constant phosphorus and potassium levels significantly affected the growth attributes of cardamom plants. At the end of the experiment (360 days after fertilizer application), the growth attributes viz., plant height (222.92 cm), plant spread (NS- 231.43 cm and EW- 215.44 cm), number of tillers (36.33) and number of leaves per tiller (16.00) were obtained maximum in treatment T5 (N: P2O5:K2O @ 150:75:200 kg/ha/year).
