- 1. LABORATORY EXERCISE NO.5 COLLECTION, CLASSIFICATION OF WEEDS BASED ON THEIR MORPHOLOGICAL CHARACTERISTICS
- 2. INTRODUCTION Weeds are unwantedplants that compete with crops for water, nutrients, and light. To manage weeds effectively, we need to know what they look like. In this lab exercise, we'll collect and classify weeds based on their physical characteristics, such as leaf shape, stem growth habit, and flower type. By learning to identify weeds, we can develop practical skills to recognize and manage
