Soil erosion due to traditional mode of farming is considered a serious environment constraint to agricultural and rural development in Maharashtra state of India. This paper attempts to study the impact of Gawsud watershed project on changes in land use pattern and cropping pattern of selected farmers. In the study comparison has been made between beneficiary and non-beneficiary farmers in the command area of the project. The comparative study indicated that the land holding was higher on beneficiary farms, while irrigated area was higher in beneficiary than non-beneficiaries. The cropping intensity was higher in beneficiary farm (170.75 %) than non-beneficiary (159.02 %). Area under soybean, jowar, groundnut and sugarcane was more with beneficiary farmers as compared to non-beneficiary farmers. The cropping pattern in the post development period of watershed shifted in favours of commercial and high value crops. Such an analysis will help in launching different programmes for developing agriculture in the state. Result of study will help policy makers,administrators and research worker for development of agriculture in different fields to plan their strategies for overall development of stateKeywords

This communication discusses the optimization of key factors for the enhanced bio-hydrogen production from water hyacinth. Three critical factors inoculums age (18-24 h), inoculums volume (20-80 ml/l) and concentration of sulphuric acid (0.5-2.0%) were optimized by response surface methodology (RSM) with central composite design (CCD) for better production. RSM analysis showed that all three factors significantly influenced hydrogen production. The optimum hydrogen production was 705 ml/l obtained with 21 h old bacterial culture, 50 ml/l inoculums with 1.25% sulphuric acid pre-treatment. The hydrogen concentration produced by Clostridium acetobutylicum NCIM 2877 was enhanced after using RSM. The results obtained indicate that RSM with CCD can be used as a technique to optimize culture conditions for enhancement of hydrogen production by pre-treatment of low-cost organic substrate; water hyacinth using dark fermentation methods may be one of the most promising approaches.Keywords
