“…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].…”

A field experiment was conducted in a farmer field in Nakhon Ratchasima province, northeast, Thailand objectively to investigate the response of cassava, Huay Bong 80 variety to phosphorus (P) fertilizer in Warin soil series (classified as Grossarenic Paleustults) amended with cassava tails and stalk (CTS) mixed with bentonite (BTN). The experiment was arranged in split plot with four replications. Main plot consisted of four rates of CTS +BTN: 0+0, 6.25+1.25, 12.5+2.5 and 25+5 t/ha while subplot comprising four rates of P fertilizer: 0, 25, 50 and 100 kg P2O5/ha. Cassava was harvested at 12-month of age and plant samples were collected at the harvesting time to study the effects of soil amendment on the uptake of primary plant nutrients in different plant parts of cassava. The results showed that the CTS+BN mixture at the rate of 25+5 t/ha highly significantly promoted the highest fresh tuber yield (FTY) and starch yield (SY) of 31.79 and 8.97 t/ha, respectively, which were 21.2 and 20.7 % greater than that of the control with no soil amendment addition. Increasing rate of P fertilization highly significantly induced greater FTY, SY and aboveground biomass (ABG) than did the zero-P fertilization. Amending the soil with 25+5 t/ha of CTS+BN along with the addition of 100 kg P2O5/ha interactively gave the significantly highest respective FTY, SY and ABG of 39.76, 11.48 and 17.35 t/ha whereas the plot amended with 12.5+2.5 kg CTS+BN/ha plus 50 kg P2O5/ha fertilization gave slightly lower STY and SY of 36.11 and 10.30 t/ha, respectively. The former combined rate of soil amendment and P fertilizer also had the interaction that highly significantly induced the highest uptake of all primary plant nutrients in the whole plant, accounting for 131.66, 14.23 and 124.13 kg/ha of respective nitrogen, phosphorus, and potassium. The result reaffirmed that amending the soil with proper rate of CTS+BTN mixture enhanced the efficiency of P fertilizer and subsequently improved yield of cassava. HIGHLIGHTS Coarse-textured soils in northeast Thailand are very poor physically and chemically, leading to low yield of cassava planted Improving the soils with proper soil amendments combined with phosphorus fertilization can be beneficial to an increase of cassava yield Amending Warin soil series, one of the coarse-textured soils in this region, with 25+5 t/ha of cassava tails and stalk + bentonite along with the addition of 100 kg P2O5/ha interactively gave the significantly highest fresh tuber yield, starch yield and aboveground biomass of cassava GRAPHICAL ABSTRACT
