“…Based on the report of IFA [37] of which to obtain a fresh tuber yield of 45 t/ha cassava needed to take up 62 kg/ha of N, 23 kg/ha of P2O5 and 197 kg/ha of K2O in tuber and 202 kg/ha of N, 73 kg/ha of P2O5 and 343 kg/ha of K2O in whole plant but in this study, considering the highest yield obtained of 39.76 t/ha in the plot received 25+5 t/ha of CTS+BTN and 100 kg P2O5/ha as an instance, N, P and K uptakes in tuber and whole plant were far lower than the quantities reported. Besides, the NPK ratio in tuber observed from this study was around 5:1:8 which was slightly different from 5:1:10 [38] and a study in Satuk soil series with higher K [39].…”

“…This was quite normal for sandy soils in general, as organic matter and N can be lost rather easily through leaching, with the former being decomposed quickly under a humid tropical climate and the latter also being lost rapidly with the removal of the cassava tubers from the field. The slight increases in the organic matter and N were similar to those observed in some studies undertaken in sandy soils in northeast Thailand (Nilnoree et al, 2016;Chaem-ngern et al, 2020;Prombut et al, 2022).…”

“…In the 2021/22 growing season, the national average yield of cassava fresh tuber was 20.83 t/ha, with 21.09 t/ha and 20.88 t/ha for the northeast and for Nakhon Ratchasima province, respectively (North Eastern Tapioca Trade Association, 2023). However, the average yield could be much higher if proper soil and fertilizer management practices were applied, as reported in some field experiments, such as 52.35 t/ha when cassava starch waste along with 75 kg/ha of N were applied in an Oxic Paleustult, in Ubon Ratchathani province (Phun-iam et al, 2018) and 51.63 t/ha when 12.5 t/ha of chicken manure were added as an organic amendment in an Ustic Quartzipsamment, in Nakhon Ratchasima province (Chaem-ngern et al, 2020). The yield of casava in the northeast, especially in Nakhon Ratchasima province, is low due mainly to the nature of soils that have a rather coarse texture with low fertility status (Anusontpornperm et al, 2009;Boonrawd et al, 2021).…”
