This study was conducted to assess and describe the visual nutrient deficiency symptoms exhibited by Shorea almon, Shorea negrosensis, and Shorea palosapis seedlings as affected by macronutrient omission. A complete randomized design was used with seven (7) treatments and four (4) replications. There were 36 seedlings per treatment per replication per species used in the experiment. The occurrences of deficiency symptoms in response to nutrient element omission on the study plants were monitored weekly. Photos on possible nutrient deficiency symptoms were taken typically on unusual colors or patterns in the leaves, burns, distortion of individual plant parts, stunting or abnormal growth. The photos were individually compared to several published literatures for confirmation. Results showed that the common characteristics of macronutrient deficiency symptoms were chlorosis on the leaf blade, interveinal and marginal chlorosis, and scorching in the leaf tip. In the later stages, necrosis starts to develop after chlorosis. Furthermore, it was observed that deficiency symptoms depend on the plant species and the macronutrients content required for optimal growth. The absence of an essential macronutrient affects plant growth and performance. When the nutrient supply was suboptimal, the morphological growth performance of the seedlings grown under no fertilizer application and -N treatments were stunted. Therefore, nutrient element omission considerably influenced the growth performance of Shorea seedlings which showed nutrient deficiency symptoms specific to the omitted nutrient element.
