Abstract
Three-year-old cardamom cv. Mudigere-1 plants were treated with organic (farmyard) manure (OM), and/or inorganic fertilizer (IF, 75:75:100 kg NPK/ha) at 25, 50, 75 or 100% alone or in combination, and control (without OM or IF), applied in 2 splits (June and September) in a field experiment conducted in Mudigere, Karnataka, India during May 1997 to January 1998. Plants treated with 75% OM + 25% IF were the tallest (225.75 cm) and had the highest number of capsules per clump (342), whereas those treated with 50% OM + 50% IF had the largest leaf area per clump (40 732.75 cm2) and leaf area index (1.25). Plants treated with 100% IF had the greatest number of bearing suckers per clump (9.96) and of panicles per clump (23.15), and green (707 kg/ha) and dry (184 kg/ha) yields. Treatment with 100% IF gave the highest total (Rs 55 092.00) and net (Rs 41 637.79) returns, and benefit cost ratio (4.19).
