Abstract : Green mustard is a kind of vegetables that is easy to plant and it has nutrition for our health. The method to use or select varieties is a good technique to yield of green mustard and fertilizer also plays a key role to increase the growth of green mustard. The purpose of this research was to show the method for using cow manure with the levels of nitrogen fertilizer in responding to growth and yield of varieties of green mustard (Brassica juncea). This experiment had two factors such as three varieties of green mustard and cow manure with the three levels of nitrogen fertilizer. Factor number one was the green mustard varieties (Brassica juncea): (V1) the pretty mustard, (V2) the black mustard (coss) and (V3) the green - leaf mustard. Factor number two was the use of cow manure of 20 t/ha with three levels of nitrogen fertilizer: (F1) nitrogen fertilizer of 0 Kg/ha, (F2) nitrogen fertilizer of 15 Kg/ha and (F3) nitrogen fertilizer of 30 Kg/ha. The experiment was done by using Randomized Complete Block Design (RCBD) with 4 replications, 9 treatment combinations, which were equal to 36 small plots. It was done at Thmor Sar village, Svay Chrum commune, Svay Chrum district, Svay Rieng province, Cambodia from September to December, 2022. The results showed that the higher yield of green mustard was the treatment combination of (V3F3) and it provided 8.92 t/ha. So, it could be concluded that the better variety of green mustard was V3 (green - leaf mustard) by using F3 (fertilizer) cow manure of 20 t/ha with nitrogen fertilizer of 30 Kg/ha that it could provide a higher yield (8.92 t/ha).
