Lahar sediment areas represent drought-prone growing ecosystems due to their sandy texture and low organic matter. Peanut, a rainfed crop has been a common option in such areas, where yields are usually less than 1.0 t/ha. Hence, on-farm trials were conducted in farmers' field in rainfed lahar-sediment areas of Pampanga, Philippines to introduce and evaluate the yield performance, reaction to diseases, profitability, farmers' acceptability and market preference of drought-resistance. Introduced varieties were the pink-seeded NSIC Pn11 and red-seeded ICGV 99046 which were compared with red-seeded farmers' variety in both wet and dry seasons. Varieties were arranged in randomized complete block design of four replicates. Pod yield of introduced varieties ranged from 2.4 to 3.0 t/ha, higher than that of farmers' variety (1.7-1.9 t/ha) in both seasons. ICGV 99046 recorded the highest yield across two cropping seasons (2.9-3.0 t/ha). High yield of introduced varieties was associated with greater pod number per plant, higher 100-seed weight, higher shelling percentage, longer number of days to maturity and resistance to fungal diseases. Net farm income from adopting introduced peanut varieties was 123-230% higher than that obtained using farmers' variety. Red-seeded varieties are predominantly preferred by farmers and market entities. The study demonstrated the advantage of adopting red-seeded ICGV 99046 for improving farm income, and acceptability by farmers and market entities.
