- Аннотация: is a shortage of organic matter so that the productivity of land for rice is very low. Therefore the eff ects of commercial humic product Lignohumate AM® (LH) on plant growth, yield, and grain quality were evaluated in a fi eld trial using traditional wet rice (Oryza sativa L.) cultivation in Bali, Indonesia. The experimental design included insecticidal sprays with beta-cyfl uthrinat 100, 50, and 0% of recommended application rates, either alone or in combination with LH. The LH was also applied for seed pre-treatment before sowing. For non-LH treatments, equal amounts of water were used. Plant growth variables and substances contents of the treated rice were recorded. The data were variant analysed according to a randomized complete design and the diff erences among treatments were compared by Duncan Multiple Range test at levels of 1% and 5%. No signifi cant eff ects on plant height, number of tillers, leaf number, leaf area or rice yield were recorded. LH stimulated root growth at early stages of plant development, promoted chlorophyll synthesis in leaves, and increased 1000-grain weight and number of grains per hill. Due to the increased level of chlorophyll, LH application promoted an increase in carbohydrate levels and amylose content in rice. The experiment showed that when using LH, rice can be grown at signifi cantly lower doses of pesticides than is currently used. Key words: rice cultivation, humic product, grain quality
