ABSTRACT
The effects of durian fertilization based on soil analysis in improving efficiency use of durian fertilizer
were assessed during two consecutive crop season of 2017 and 2018 in farmer’s durian orchard of the
upper southern region; Ban Na Subdistrict, Ban Na Doem District, Surat Thani, geographical coordinates 47P
537797 E 981415 N ATL 44 m. A completely randomized block design with seven replicates was adopted,
in which the three fertilizer treatments were established: 1) farmer practice of fertilizer use in rate of 1,480-
1,110-2,240 g of N-P 2O 5-K 2O /tree/ year; 2) soil analysis based fertilizers for targeted durian yield at the rate

1,150-490-1,710 g of N-P 2O 5-K 2O /tree/year; and 3) a fertilizer rate based on classified soil texture at the
rate 1,1 3 5 -1,1 0 0 -1,670 g of N-P 2O 5-K 2O /tree/year). It was found that application of soil analysis based
fertilizers for targeted yield at the rate 1,1 5 0 -4 9 0 -1,7 1 0 g of N-P 2O 5-K 2O /tree/year achieved yield and
consumption quality of durian were not statistically different in comparatively to farmer practice of fertilizer
application. The average yield between 2 seasons in respectively are 141-144 and 173-193 kg/tree. Even
though, the amount of chemical fertilizer was decreased based on soil analysis but the yield and
consumption quality recorded which this fertilizer rate was still not statistically different to farmer practice

of fertilizer use. In addition, over two seasonal crops, not only the amount of fertilizers were reduced
according to soil analysis based fertilizers for targeted durian yield but the cost of fertilizers was also reduced
lower than that of farmer practice of fertilizer use in which 1 8 %, and the fertilizer application method
according to based on soil analysis has more benefit cost ratio (BCR) than the fertilizer application method
according to rate of farmer practice in both seasons by 5.39 and 8.81, respectively.

Key words: Durian, fertilizer, soil analysis, soil texture
