EFFECT OF NPK BIO-ORGANOMINERAL FERTILIZER ON RICE PLANT (ORYZA SATIVA L.) IN TEXTILE WASTE POLLUTED SOIL: PLANT GROWTH AND YIELD

Pollution of agricultural land in Rancaekek caused by textile industry waste entering through irrigation water has resulted accumulation heavy metals in the soil and a decrease in rice yield productivity of only 2-4 t ha-1 . Overcoming this problem requires inputs in the form of fertilizers that can increase yield and plant growth. The objective of this experiment was to analyze the effect application of NPK Bio-organomineral fertilizer (NBO), which is a fertilizer that combines organic, inorganic, and biological agents on contaminated soil of textile industry waste planted with paddy rice plants on plant height, harvested dry unhusked rice, and 100-grain weight. Based on ANOVA test, the application of NBO fertilizer significantly affected the growth parameter, specifically plant height and yield parameters, such as harvested dry unhusked rice and 100 grain weight. Treatment F (NBO 500 kg ha-1 ), showed the best results in the parameter of plant height at 56 DAT, whereas at 70 DAT, treatment C (NBO 125 kg ha-1 ) is the best result. The best treatment on yield parameters is shown by treatment G (NBO 675 kg ha-1 ) for harvested dry unhusked rice, while the best result for the weight of 100 grains was shown by treatment F (NBO 500 kg ha-1 ). This study found that the application of NBO fertilizer, which is a combination of organic, inorganic, and biological agents, was able to increase the height and yield parameters of rice plants grown in soil polluted with heavy metals from textile industry waste
