Abstract
Use of humic acid has great significance to improve soil quality and crop yield in loess hilly and gully areas. In the present study, potassium humate (PH) and potassium fulvic acid (PFA) were used as soil amendments in gully the control project area of Yan'an City, Shaanxi Province. A pot culture experiment was conducted to evaluate the influence of two types of humic acid (PH and PFA) on the growth characteristics of ryegrass in the loess hilly and gully area. Results showed that application of potassium humate and potassium fulvic acid considerably increased the chlorophyll synthesis as well as root length of ryegrass. When the proportion of PH and PFA was the same, the effect of PFA was to be found better than that of PFH. When the proportion of potassium humate was 15g/kg soil, the leaf chlorophyll content and root length attained the maximum, and the soil maturity effect was the best.

期刊介绍：
Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments.
Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December.
Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
