Abstract

Water stress has a strong influence on the physiological functions of tree crops which adversely affects the growth and yield of tree plants. Drought and soil fertility are the major factors that influence seedling survival and growth in arid areas, thus it is of paramount importance to establish optimum water requirements for tree seedlings in order to promote growth. In line with this, an investigation was carried out to assess early growth behaviours of Anacardium occidentale when exposed to varied watering intervals in the greenhouse. Two month old grafted seedlings were used for the study in 1.08 liter plastic pots containing 2 kg of potting soil. Seedlings were exposed to five different watering intervals (every two days, every four days, every six days, every eight days and ten days) and 80 mL of water was administered per each seedling based on the watering frequency for two months. Six seedlings were allocated per watering frequency and replicated 4 times in a Split-plot design. The result revealed a significant effect of irrigation frequency on seedlings growth of Anacardium occidentale where seedlings that received water every two days and every four days produced highest growth in the variables measured. Administering 80 mL of water per seedling every two days and every four days improved growth of A. occidentale in the nursery.
