Effects of Photosynthetic Bacteria and Bio Extract on Growth and Yield of RD43 Rice Cultivated in Organic Systems
Keywords:
photosynthetic bacteria, bio extract, yield, RD43 rice, organic systemAbstract
This research was conducted in order to study the effect of Photosynthetic Bacteria (PSB) and LDD 2 bio extract on growth and yield of RD43 rice cultivated in organic systems. The experiment was performed in CRD with 4 treatments: control (chemical fertilizer), PSB, LDD 2 bio extract, and PSB with LDD 2 bio extract, 4 replications, 25 pots per replication, and 3 plants per plot. The results showed that there was none statistically significant (p>0.05) of all parameters among 4 treatments including survival rate, plant height, number of tillers, leaves chlorophyll content at both 30 and 50 days after transplanting, amount of days for flowering and harvesting, number of spike per plant, number of seed per spike, and number of good seed. Furthermore, the qualities of seed such as width, length, and weight of seed and weightof seed without hull were none statistically significant also. Therefore, the PSB, LDD 2 bio extract, and PSB with LDD 2 bio extract may apply for RD43 rice production in organic system instead chemical fertilizer.
