Three field experiment, were conducted on herbs using basil (Ocimum basilicum), oregano (Coleus aromaticus), and thyme (Thymus vulgaris) to determine the yield response of herb species to fertilizer applications, irrigation methods, and mulching. In the first experiment, N fertilizer was applied to oregano at O, 50, 10(1, and 200 ltg/ha. In the second experiment, basil was fertilized with 0, :18, 75, and 113 ltg N/ha in combination. with O, 13, and 25 ltg P/ha. Micronutrients in the form of Micro-Max R were added at the rate of 34 ltg/ha to the treatments with 0-0-0, 75-13-0 1 and 113-25-0 N-P-K (ltg/ha). The third experiment determined the effect of two irrigation methods (drip vs. sprinkler), two irrigation ratea (40 vs. 60%. Pan ET), and mulching on yield and minimum water requirement of thyme. Fresh and dry matter yields or oregano leaves, were significantly increased by N application of 100 to 200 ltg/h11, There were no significant yield differences between treatment, suggesting that 50 and 100 ltg/ha may be the minimum and optimum N rates, respectively, for oregano production. No distinct pattern on yield was observed for basil receiving various Combinations of N, P, and micronutrients. For thyme, treatments with drip irrigation of low (40% Pan ET) and high (60% Pan ET), both without mulch were superior in yield to other treatments. The minimum water requirement of thyme appeared to be 40% Pan ET.
