Abstract

Attitudinal and opinion change after involvement under technology assessment and refinement programme was studied in five villages of Karge Panchyat in Mandar Block of Ranchi district in Jharkhand, which revealed that demonstrating and experimenting farmers had relatively higher degree of positive attitude related to intervent technology in comparison to the participating farmers. The independents variables, namely, education, caste, socio-economic status and annual family income had positive and significant correlation with the attitude scores, while age was found to be negatively and significantly correlated. The findings on farmers' opinion on refinement of intervened technologies revealed that the refined technologies were found to be problem-solving, need-based and location-specific which were highly compatible with the farming systems components and household internal resources. Since the technologies were found to be profitable and appropriate for meeting the requirements of household food security they found favours and preferences by the respondents

Abstract

In the type area of the charnockites, south of the city of Madras, foliation attitudes of marker horizons of leptynites and of basic granulite bands trace a map pattern characterized by four-fold hinges. The overall structure of the area is brought out by the swerve of axial planes of these folds from NNE in south-west through E-W in the central part to N-S in southern part in a broad sweep. The folding is noncylindrical; and a probable structural interpretation, as advanced here, envisages a series of tight isoclinal folds on which a folding around a N-S axial plane has been superposed.

Abstract

The Precambrian Dalma metabasalts stretching for more than 200km represent original oceanic tholeiites. The metabasalts can be represented by eleven different groups of mineralogical assemblages ranging from low greenschist to high amphibolite facies. Spatial distribution of these six groups indicates increasing P-T conditions from east to west.

Abstract

The Arkasani granite gneiss occurs as detached elongate outcrops close to the northern margin of the Chakradharpur granite gneiss. Both show imprints of the same deformation and same textural and structural characters. While the Chakradharpur gneiss ranges from tonalite - granodiorite - granite - alkali feldspar granite, the Arkasani gneiss is an alkali feldspar granite. Major element compositions of the two are either gradational or overlapping. The former has higher Na₂O values and the latter higher K₂O values. The two groups of gneisses are genetically related.

Abstract

Petrology and mineral chemistry of garnetiferrous chlorite schists belonging to Deogiri formation in the Sandur schist belt have been studied. Mineral assemblages and chemical data on muscovite, biotite, chlorite, garnet from the Deogiri chlorite schists indicate low grade regional metamorphism under greenschist facies condition. Mineralogy of the metabasics associated with Deogiri chlorite schists and with the overlying Donimalai formation in this region, except near the peripheral contacts, also suggest greenschist facies metamorphism for the schist belt. Mineralogy and chemistry of Deogiri metabasalts indicated ocean floor type of alteration/metamorphisrn for the Deogiri metabasalts. Rocks close to the granite contact have seemingly undergone an episode of thermal metamorphism which is distinct from the regional metamorphism of the entire schist belt and possibly isolated both in space and time.

Abstract

Technological interventions with respect to rice production and suitable methods of approach for transfer of technology under rain fed and irrigated areas to sustain a livelihood system specifying attributes of innovations were studied taking 240 respondents from 4 villages comprising both rain fed and irrigated situations. It was found that the extent of adoption was highest in nutrient management followed by variety replacement, whereas in irrigated condition variety replacement toped the list (70.83%) followed by nutrient management, SRI method. The 'z' value was found to be significantly different in case of SRI method, nutrient management and variety replacement whereas extent of adoption of IPM and hybrid rice cultivation remains same. The 'zr' value of 4.19 in case of rainfed condition implies rice cultivation is a huge water-demanding enterprise. However, role of poverty reduction and feedback system registered minimum role. Market was also an important component for paddy technology adoption.

Abstract

Sustaining soil and land quality under intensive land use and fast economic development is a major challenge for improving crop productivity in the developing world. Assessment of soil and land quality indicators is necessary to evaluate the degradation status and changing trends of different land use and management interventions. During the last four decades, the Indo-Gangetic Plains (IGP) which covers an area of about 52.01 m ha has been the major food producing region of the country. However at present, the yield of crops in IGP has stagnated; one of the major reasons being deterioration of soil and land quality. The present article deals with the estimation of soil and land quality indicators of IGP, so that, proper soil and land management measures can be taken up to restore and improve the soil health. Use of principal component analysis is detailed to derive the minimum dataset or indicators for soil quality. The article also describes spatial distribution of soil and land quality with respect to major crops of IGP.
