The effect of drying RTDVs on the growth of wheat plants. The plants were supplied with deionized water daily as a negative control (“black square symbol”), 20-20-20 fertilizer daily as a positive control (“red circle symbol”) or RTDVs at the start of the experiments. The RTDVs were loaded at 100% dose of 20-20-20 fertilizer and dried in the oven at 80°C for 0 h (“blue triangle symbol” RTDV 6), 24 h (“pink triangle symbol” RTDV 7), 48 h ("green triangle symbol" RTDV 8). Plant height (mean ± S.D., n = 3) is reported.
