Abstract

This study focused on effects of vermicompost-chemical mixed fertiliser on the growth and macronutrient content of
upland rice cv. Sakonnakhon in Khon Kaen province, Northeast Thailand. The experiment was carried out under greenhouse
conditions. Five treatments were compared: T1 (control without fertiliser); T2 (chemical fertilisers, 156.25 kg ha^-1 NPK 16-16-8
and 62.5 kg ha^-1 NPK 46-0-0); T3 (vermicompost, 6,250 kg ha^-1
); T4 (vermicompost, 6,250 kg ha^-1
and chemical fertilisers,
78.125 kg ha^-1 NPK 16-16-8 and 31.25 kg ha^-1 NPK 46-0-0) and T5 ( vermicompost, 6,250 kg ha^-1
and chemical fertilisers,
156.25 kg ha^-1 NPK 16-16-8 and 62.5 kg ha-1 NPK 46-0-0). The results showed significant effects on rice yield components from
the application of T4 and T5. With regard to rice yield, the application of T3 ( vermicompost, 6,250 kg ha^-1
) had significant
effects on spikelet number, average grain number and total grain weight.
