This study was conducted to determine the comparison of photosynthetic rate between organic and inorganic plant with mustard greens (Brassica juncea) as sample. The experimental design was a randomized block design with 3 times respectively using compost for organic crops and NPK for inorganic crops. Doses used is 20 g / kg soil for both. The results showed an average increase of oxygen pressure in the light reactions of organic crops is 0.123 hPa/s whereas the inorganic plant is
0.028 hPa / s. The average pressure of oxygen organic crops decreased to 0.104 hPa / s whereas the inorganic plant -0.037 hPa / s in the dark reaction. Analysis of the data in this study using the unpaired t test and the results showed a significant difference between the rate of photosynthesis in plants organic and inorganic.
