Abstract

The microorganism based products consists of special selections of microorganisms that can accelerate the decomposition of organic matter enhance the availability of plant nutrients and improve soil fertility. They are also claimed to be able to replace chemical fertilizers in the long term and are suitable for organic farming. The studies were carried out to assess the effectiveness of these products on rice and vegetable crops. Field trials and planthouse studies on the use of 2 types of microorganism based products : 1 Bioferty 2 Effective microorganism EM4 were carried out on rice and vegetable crops. Soil exchangeable ammonium nitrogen was measured in the rice field. In the pot trials with short term vegetables Ipomoea aquatica and Amaranthus spp. the application of Bioferty without the application of chicken dung CD gave significant increases in yield over the Control without NPK and NPK treatments. This would indicate that Bioferty may be able to release nutrients from the available organic matter in the soil which enhanced the growth of these short term vegetables. A third pot trial was carried out to probe the role of Bioferty on organic matter and therefore CD was applied to all the treatments. The highest yield was again obtained with CD Bioferty which was significantly higher than CD and CD NPK treatments. It is clear that Bioferty is effective in enhancing the yield of short term vegetables. In field trials with long term vegetables Brassica oleracea in Linggi and Cemeron Hinglands Bioferty was not effective in enhancing the yield.
