Experiment Title Study on bacterial decomposition of cotton stalk in the soil and its effect on cotton seedling growth
Research Type Lab Research
Experiment Background Cotton stalk is the richest source of lignocellulose and microbial decomposition of cotton stalk into the soil will release such end products. The type of end products release through microbial community in the soil depend on factors like type of microbes, chemical composition of soil, type of crop, cropping system etc. In case of cotton crop, previous study showed that microbial decomposed cotton stalks promoted seed germination of cotton (Zhang et al., 2011). Beside this, it was also reported that the long term continuous cropping is one of the factor that decrease the population of natural microflora, decomposition rate of stalk as well as nutrients releasing patterns (Neri et al., 2005 and Wright et al., 2007) in the soil. Also, such microbes can give allelophathy effect on plant growth (Yu et al. 2000; Narwal 2006; Tesio et al. 2012). Thus, the end product generated through bacterial degradation of cotton stalk in the soil play crucial role in the plant growth. Thus, our present work aims to study the decomposition of cotton stalk in the soil by the isolated bacteria and its effect on cotton seedling.
