Description
A questionnaire survey and a set of field experiments were conducted in Heho Horticulture Farm, DOA, Kalaw Township, Southern Shan State to explore the farmer practices on Chinese cabbage pro-duction, and to investigate the effect of different fertilizers on yield, nutrient uptake and nitrogen (N) use efficiency of Chinese cabbage in peat soil and red soil during the winter season, 2016-2017. The experi-

mental design was randomized complete block design with four replications. The treatments were T1 (control), T2 (20 t cowdung manure (CM) ha−1), T3 (200 kg N ha−1), T4 (160 kg N ha −1), T5 (120 kg N ha−1), T6 (100 kg N ha−1 + 10 t CM ha −1), T7 (80 kg N ha−1 + 10 t CM ha−1), T8 (60 kg N ha−1 + 10 t CM ha−1) and T9 (farmer practice, FP; 104 kg N ha−1 + 11 t CM ha−1).

According to the survey results, all farmers used cowdung manures and compound fertilizers (15:15:15) in Chinese cabbage production. Generally, 2.5 – 5 bags of 50 kg urea ha−1 and 5 – 7.5 bags of 50 kg compound fertilizer ha−1 were applied. In peat soil, T3 gave the highest yield but, the highest ap-parent N recovery (ANR) was obtained from the lower N application rates (T4 and T5). FP gave lower yield compared to T3 and T4. In red soil, the highest yield, nutrient uptake and ANR were observed from T4. T6 might be suitable fertilizer application practice in red soil due to its high yielding capacity and high Benefit-cost ratio (BCR). In respective treatments, yield (fresh weight), N uptake and ANR were greater in red soil compared to peat soil.
