Abstract

Bamboo is one of the fastest growing plant species which occurs under varied climatic and edaphic conditions. In the present review the distribution and productivity of different species of bamboo in India have been discussed. The climatic and edaphic conditions suitable for the optimum growth of some important bamboo species have also been described along with bamboo based agro-forestry models.

Abstract

Ground flora are more sensitive to changes in environment than trees Amarkantak plateau being at higher elevation has a privilege to cooler climate. Due to higher elevation, climate of Amarkantak is closely resembling with isolated valleys or islands. Amarkantak is truly unique place for this study because it has many valuable plants which are now grossly endangered in nature. The measurement of different phytosociological attributes like density, Importance Value Index, population distribution and diversity in different season have been studied in Amarkantak (Madhya Pradesh) during 1996-97 under plantations (Eucalyptus and pine) and natural sal forest. The range of number of species recorded in rainy season was highest (15-21) under Eucalyptus plantation, followed by under pine plantation and under natural sal forest, and lowest in summer (5-9) under Eucalyptus and pines plantation,. The range of IVI was highest in summer than in winter and rainy season. The population distribution was generally contiguous and random but in winter and summer the regular distribution was also involve due to severe competition for resources. Diversity index was maximum 0.245, 1.2024 and 1.3333) in rainy season and lowest (0.3950, 0.65930 and 0.946) in summer under Eucalyptus, pine plantations and natural sal forest respectively. The best adapted nich area was observed for Ophioglossum reticulatum, Ageratum conyzoides and Adiantum sp. On the basis of highest IVI in natural sal forest, Eucalyptus and pine plantations respectively. Dominance Diversity curves tended to assume the form of a series more distinctly in the winter and summer seasons, when climatic conditions are not congenial for plant growth. Thus all the vegetational changes in structure and composition are mostly dependent on seasons.

Abstract

The rate of decomposition was highest in litter of sal (0.0105 g g^-1 day^-1 ) than eucalyptus (0.0102 g g^-1 day^-1 ) and pines (0.0090 g g^-1 day^-1 ) in Amarkantak (M.P.). The number of microarthropods were more in sal than eucalyptus and pines and diversity of micro-arthropods were also higher in sal (1.4520) than eucalyptus (1.2778) and pines (1.3661). Micro-arthropods multiply during rainy season when the rate of litter decomposition is maximum. As decomposition proceeds, the composition of the litter continuously changes, creating new condition for the decomposing organisms. The fast disappearance rate of litter during rainy season might be due to accelerated growth of microbial population as well as their activities to decompose the material in presence of sufficient moisture and optimum temperature, while it was moderate in the season and at a very low rate in the summer season.

Abstract

The present paper deals with the traditional knowledge gathered on medicinal plants used against various diseases from traditional herbal healers of Harda and Raisen districts of Madhya Pradesh, India. Information collected from the traditional healers locally known as Vaidhya/Ojha has revealed that plant/plant parts of 37 species from Harda district and 60 species from Raisen district of forest origin are being utilized as paste, powder, juice, decoction and extract for the treatment of various human diseases. Habit and utilization of plants and the percentage of different formulation of herbal medicine being prepared by the herbal healers of the study area have also been documented.

Abstract

The object of this paper is to present the principal issues relating to regional planning in India. It is divided into two parts. Part I describes the issues, the thinking relating to them, and the experience with some regional-planning policies, during the period of the three plans. Part II describes the politico-administrative structure within which planning is done in India, and the contribution of regional-planning techniques to improving efficiency of planning through this structure. The question of planning-regions has been discussed briefly, and the regions which can be easily incorporated within the politico-administrative structure, and some others which may need to be added for particular planning purposes, have been mentioned.

Abstract

A Crop Diversification Promotion Project (CDP) was implemented in Himachal Pradesh (HP) with the collaboration of the Japan International Cooperation Agency-Official Development Assistance (JICA-ODA) in 2012. It lasted for 7 years with the objective to improve the socio-economic status of farm families. The operational area had 210 sub project sites spread over five districts viz., Bilaspur, Hamirpur, Kangra, Mandi and Una of the state. The project was implemented following a comprehensive package of multi-pronged strategy encompassing infrastructure development (such as irrigation, farm access roads, markets, etc.), inputs supply (seeds, fertilizers, farm machinery, etc.) supported by technical and capacity building programmes and strengthening of extension services and organized marketing. The impact study on socioeconomic status of farm families was carried out based upon the extensive review of information collected from the status reports and evaluation studies conducted by different agencies in the operational area. Study revealed that CDP project has been quite successful in improving the socio-economic status of farm families across project sites. There has been increase in the irrigated area and the area under vegetable crops. Cropping pattern changed resulting into 35-50 per cent of the farms being highly diversified with 50 per cent of the area under vegetable crops. In general, the extent of diversification was 9.69 per cent for vegetables crops in Mid and Low Hills under HPCDP-JICA project. Farm productivity and income increased by more than 3.5 times over the baseline income. In some cases increase in income was 5-6 times. The increase in income was attributed to several contributing factors and interventions carried out under HPCDP initiatives. Major contributors were found to be assured irrigation, capacity building programmes, introduction of improved varieties/ cultivation practices and proper/ balanced use of nutrients. Operational farm efficiency also registered improvement due to use of improved tools and machinery provided under the project. Overall, the project enhanced the cropping intensity, productivity, production and marketed surplus. Keeping in view, the impact on raising income and food security of farm families, it is advocated to expand the HPCDP domain to cover farm families in all districts of Himachal Pradesh.
