Abstract
Application Farmyard manure in rainfed lowland can be a good alternative for sustainable agriculture. The objective of the study was to know the effect of organic and inorganic fertilizer on available P content, growth and rice yield. This study used a Randomized Block Design with six treatment and three replications. The treatments were the control, NPK, cow manure 10 t ha−1, cow manure 10 t ha−1+ NPK, cow manure 20 t ha−1, cow manure 20 t ha−1+ NPK. This study was conducted at Jakenan, Pati and has been carried out since 2015. Data on growth and yield were analyzed statistically using ANOVA. Available P data were analyzed descriptively. The results showed that the use of cow manure alone of 20 t ha−1+ NPK for 4 years was able to increase the available P content from 6.62 ppm to 290.27 ppm. Application cow manure alone or combine with inorganic fertilizer (NPK) gave a significant effect on vegetative growth parameters than the control treatment. Long-term application (4 years) 10 t ha−1 cow manure can increase Inpari 43 yield 135% and significantly different to control. The application of cow manure in the long-term can be considered for sustainable crop production in the rainfed lowland.
