In this paper, growth and storage of carbon and nitrogen in seedlings of banj oak (Quercus leucotrichophora A. Camus) and chir pine (Pinus roxburghii Sarg.) have been compared across different levels of nutrient and water availabilities. Four nutrient (144, 264, 384 and 504 mg of NPK fertilizer per kg soil) and three watering (21 days,14 days and 7 days interval) treatments were applied to seedlings. At low watering levels, seedling dry mass of both the species decreased towards higher nutrient level. However, at high watering level, dry mass increased with increasing water availability. When water availability was increased in a constant nutrient environment, dry mass of seedling increased with increase in water availability. Both the species showed a similar pattern of storing nitrogen instead of increasing biomass particularly at low watering levels. However, at each nutrient level, growth and storage increased with increasing moisture availability. As compared to Q. leucotrichophora, seedlings of P. roxburghii favoured growth over storage (according to its more competitive strategy), although this species accumulated more carbon and nitrogen towards the higher nutrient level.
