Yield and Nitrogen Use Efficiency of Upland Carrot Affected by Various Basal Fertilizers and Fertigation Ratios

Fertigation is one of alternative measures not only to ensure crop yield but also improve nutrient use efficiency. In this work, we evaluated growth and yield, uptake nitrogen efficiency upland carrot. To do our goal, various basal fertilizers (single chemical slow release) fertigations were employed based on the result soil diagnosis, detail was as follows; basal:fertigation = 100:0, 50:50, 30:70. Growth, (N, P, K) different from treatments. However, release fertilizer resulted in enhancing economic (root) compared single fertilizer, an adjustment basal:top dressing (fertigation) relatively effective. conclusion, current results suggest that fertigation favorable for carrot production, further study including comparison with conventional practice (broadcasting) organic a source required validate effect.Economic under condition rates. ns: no significance.
