       Shallot is an important commodity that becomes the basic food needs of the Indonesian people. Farmers generally use chemical or inorganic fertilizers in their cultivation activities. Inorganic fertilizers can accelerate the growing period because the nutrients can be absorbed directly by the soil. However, the continuous use of inorganic fertilizers can harm the soil and the environment, then to avoid this is to switch to using organic fertilizers. Manure is one of the organic fertilizers that can increase the availability of nutrients for plants. With the presence of intensive bacteria, it can accelerate the availability of nutrients. Bacteria whose role is to decompose organic matter are called PGPR. This study aims to (i) know the interactions (ii) know the single factor of cow manure (iii) know the single factor of bamboo root PGPR (iv) get the best interaction (v) get the best dose of cow manure (vi) get the best dose of bamboo root PGPR. This research was carried out in alluvial land in Tabalong District from March-June 2019. This study used a factorial randomized block design with the treatment is a dose of cow manure, namely: p1=10 t/ha, p2=20 t/ha, p3=30 t/ha, while the bamboo roots PGPR are: b1=20 ml, b2=25 ml, and b3=30 ml, so the combination is 9 treatments. The results showed that the observed variables were plant height, number of leaves, number of tubers, tuber diameter and tuber weight only affected plant height with a single factor treatment of cow manure and the best dose was 20 t/ha.Shallot is an important commodity that becomes the basic food needs of the Indonesian people.

One of the recommended concepts of organic agriculture is the use of organic fertilizers and minimizing the use of inorganic fertilizers in farming activities or crop cultivation. Manure is one of the organic fertilizers that are often used as fertilizer, one of which is goat manure. In addition, there are several types of household waste that can be used as liquid organic fertilizers such as the waste rice washing water that can be applied to plants. The research objective were to determine the effect of giving rice washing water waste and manure to the growth and yield of mustard plants. This research was conducted from February to April 2017. This study used a randomized block design with two factors consisting of 16 treatments and repeated three times. The first factor isto control rice washing waterwith a concentration of 10, 20 and 30 ml/liter of water and the second factor is manure consisting of control, manure 5, 10 and 15 grams. This study uses quantitative data analysis techniques. Analysis of quantitative descriptive data used is plant height and number of leaves.Observation results of plant height showed that the highest average of plant height was experienced by 20 ml/liter rice washing water and 15 goat manure treatment. Likewise, the average number of leaves of mustard plants was not significantly different from the treatment of rice washing water, but the number of leaves in mustard plants was not significant. The results showed there were no significant interactions between the concentration of rice washing water and manure doses on growth and yield of mustard greens The rice washing water did not have a significant effect on plant height and number of leaves. The difference in the results of this study was thought to be caused by differences in the types of rice used.
