Evaluation of Fertilizer Management on Different Maize Varieties in Southern Shan State

The study was carried out with two objectives (1) to observe the highest fertilizer response on growth performance of grain maize varieties and (2) to determine the effect of fertilizer management practices in response on yield and yield components. The field experiment was conducted at Aung Ban Research Station under Department of Agricultural Research by using split plots design with three repli-cations. Five maize varieties were used as tested varieties under four levels of fertilizer management practices. Sustainable and Affortable Poultary for All (SAPA) fertilizer application practice gave the highest grain yields, yield components and agronomic parameters than the others. It may be probably due to higher fertilizer application rate together with micronutrients especially more potassium applica-tion with S, Ca and Mg than other practices. Among the varieties, NK 621 variety gave the maximum yield, yield components such as number of kernels per row, thousand seeds weight and agronomic char-acters such as SPAD value, ear weight and ear diameters. “In combination effect of SAPA fertilizer and SA 282 variety gave the maximum yield but the yield of SA 282 was not significantly different with NK 621. Therefore, these two varieties were found as the best performing in grain yield and good potential for the future in Southern Shan State
