Crop potential has been brought out over the red-laterite-gravelly belt of West Bengal using Moisture Availability Index (MAI) and broad soil information. MAI indicates that a crop of 15. 18-20 and 22-24 weeks. duration at 80%, 50% and 30% probability levels respectively maybe raised from this belt. In most of the stations of the belt, rice could be raised in eight out of every ten years without encountering much waterstress period. At lower probability levels. after rice, pulses like gram. tur and lentil and oilseeds like rapeseed and mustard may be raised based on residual soil moisture. In low rainfall years sorghum. groundnut, maize could be introduced in place of rice in the kharif season. Emphasis should also be given on agro-forestry and horticultural crops for increasing and stabilizing agricultural production.

Seasonal Droughts

Weather aberrations impact agriculture and allied sectors in one or other parts of the India round the year. Seasonal droughts and extreme weather events in 21st century have caused alarming losses not only in agricultural production but also horticulture, livestock, poultry and fisheries. ICAR-CRIDA, SAUs and DAC, MoA, GoI, prepared more than 580 district level agriculture plans within formation on contingency measures for sustaining higher agriculture production and to cope with extreme events. Real-time contingency planning (RTCP) is being conceptualized and implemented at micro level in farmers’ fields in this country. RTCP implementation during delayed onset of monsoon, seasonal droughts and floods resulted in better crop performance, higher agricultural production, better incomes and overall stability in house-hold livelihoods. In this paper, the real-contingency measures to cope with extreme events for management of horticultural crops, livestock, poultry and fisheries are proposed. Further, the preparedness for RTCP implementation with policy initiatives is also suggested.

The Impact

This chapter revisits the experience of land reforms in Kerala and West Bengal to provide a comparative analysis of the impact of left reformism on the nature of capital accumulation in these two states. The chapter builds on a conceptual framework combining a contemporary Marxist reading of the agrarian question and the theoretical justification of land reforms from a developmentalist perspective. The analysis in the chapter shows that land reforms were not able to generate a process of inclusive industrial development in either state. In Kerala, land reforms did not revitalize agricultural production primarily because of a powerful trade union movement leading to overpricing of labor and resistance to technological upgrading while in West Bengal the sharp increase in agricultural productivity could not be transmitted to dynamic process of capital accumulation in the larger economy. This is interpreted as a disarticulation of the accumulation problematic of the agrarian question.

Soil Surveys

In order to estimate variability of soil information presented in detailed soil surveys of the Montreal lowlands area, more than 2000 samples were collected along stratified random transects in 133 mapping units. The coefficient of variation (CV) was used as variability criteria. Variability of selected soil characteristics of the plow layer was studied according to phases of surface texture. The CV of clay, silt, pH, CEC and exchangeable cations decrease with an increase in clay content. The CV of sand content follows the opposite direction. Four modes of deposition (marine, fluvial, till and estuarine) were compared according to the variability within taxon (soil series or variant) of soil characteristics of the A, B and C horizons. More samples are needed to estimate the population mean value with the same relative error and the same confidence level for soils developed in fluvial deposits than in those formed in marine sediments. At the 90% confidence level, the allocation of 15 samples per map unit allows one to estimate the population mean with a relative error ranging from 5 to 30% for most soils and variables studied. Quality standards are proposed for soil sampling in future soil survey projects. Key words: Soil variability, accuracy, sampling, taxon, mapping unit

Feasibility of agro-industrialization of the remainder of harvest of vegetables in the province of Santa Elena Resumen La Península de Santa Elena se caracteriza por ser una zona semi-desértica, pero con un potencial agrícola extraordinario a lo largo de todo el año, especialmente en cultivos de hortícolas, para el desarrollo de una agricultura empresaria; pero uno de los principales problemas de la actividad agrícola en esta provincia son la variación constante de precios en la cosecha de las hortalizas principalmente. Así como también, problemas de plagas y enfermedades, que afectan la producción agrícola y en especial los remanentes de la cosecha, que impiden una producción agrícola sostenible, convirtiéndose en los indicadores que resultan difícil de ser controlados por los productores, quienes emplean sistemas de siembra tradicionales; obligándolos a buscar nuevas alternativas de producción hortícola. Razón por la cual, se deben implementar nuevas alternativas de producción que, sirvan para incrementar la rentabilidad de este tipo de cultivos; de tal manera que, se vean beneficiados los productores y la sociedad en general. Entre las alternativas más idóneas, se puede mencionar a la recolección, clasificación y selección del remanente de la cosecha de hortalizas como cebolla, pepino y pimiento, entre otras; para darles valor agregado, a través de la elaboración de pikles; mejorando de esta manera, los ingresos económicos de los productores, la calidad de vida y la de sus familias. Razón por la cual, el presente estudio tuvo como objetivo, realizar un estudio agrosocio-económico, para conocer la realidad de los agricultores de sector de Velasco Ibarra del cantón La Libertad, en cuanto a la producción y comercialización de los cultivos hortícolas. Palabras clave: productores; agro-industrialización; remanente; cosecha; hortalizas; pikles. Abstract The Santa Elena Peninsula is characterized by being a semi-desert area, but with an extraordinary agricultural potential throughout the year, especially in horticultural crops, for the development of a business agriculture; but one of the main problems of the agricultural activity in this province is the constant variation of prices in the harvest of the vegetables mainly. As well as problems of pests and diseases, which affect agricultural production and especially the remnants of the harvest, which prevent sustainable agricultural production, becoming indicators that are difficult to be controlled by producers, who use planting systems traditional forcing them to look for new alternatives of horticultural production. Reason why, new alternatives of production must be implemented that, serve to increase the profitability of this type of crops; in such a way that producers and society in general benefit.

<p>Consumer demands on safe agricultural products have made the shifting of the production system to be more environmental friendly. An attempt to reduce or totally substitute chemical fertilizers and pesticides on agricultural production process was through the utilization of potential microbes. The purpose of the study was to provide information on potential microbial species that can be used as active ingredients of biofertilizers and biopesticides. The mechanisms of action have been studied, both directly and indirectly, in protecting the plant from pest and disease attacks. Several of these microbes also functioned as decomposer that might improve soil characteristic and nutrient availability for the crops. The Indonesian Agency for Agricultural Research and Development for has released formulated biopesticides and bio fertilizers with the active ingredients isolated from agricultural production centers. The application of these biopesticides and biofertilizers have been effectively controlled important diseases in horticultural crops, i.e. Bio Nutri-V could suppress white rust disease (Puccinia horina Henn) 32.15% in chrysanthemum and increased 25% and 34% harvestable products in chrysanthemum and potato, respectively, compared with synthetic fungicide. The utilization of biopesticides and biofertilizers is expected to improve the competitiveness of national agricultural commodities by utilizing natural resources to support highly competitive and sustainable agricultural industries.</p><p>Keywords: Microbes, biofertilizer, biopesticide, vegetable, ornamentals, horticulture.</p><p> </p><p><strong>Abstrak</strong></p><p>Tuntutan konsumen terhadap keamanan produk pertanian menuntut pula perlunya proses produksi dilakukan secara ramah lingkungan. Salah satu upaya untuk mengurangi atau mensubstitusi penggunaan pupuk dan pestisida kimia sintetik ialah memanfaatkan mikroba.

Studying Agriculture Knowledge Information System (AKIS) in terms of generation, dissemination, transformation, utilization, storage and retrieval of knowledge and information is needed for agriculture development.  A study was conducted in Nadia district of West Bengal and Betel vine growers, Extensionist, Researchers were considered as respondents. Cultivation of betel vine is one of the most important horticultural crops at it is gradually increasing its popularity in the Nadia district as cash crop. It is observed that in- adequate information regarding Betel vine production in the sampled areas, almost cent percent growers were using their own traditional planting materials since long and growing their crops with their indigenous knowledge, skill and their past experiences. They have little awareness regarding the improved method of cultivation. The study further indicated that the respondents were receiving better information and technical knowhow about betel vine cultivation from Opinion leader, participating in training programmes, discussing with Extension personnels, input dealers, neighbours and different NGOs and to some extent from electronic media. The respondents treated relatives, neighbours and co-operatives as better credible sources followed by demonstration, campaign, Argil. University expert, Krishi-mela, Leaflet and Input dealers and electronic media to some extent. Establishment of research station, transfer knowledge information system and marketing system might be useful for realising better return on betel vine cultivation and young farmers are quite enthusiastic to cultivate the betel vine and promotion of this crop should be continued in the other parts of the district for gainful employment through need based and location specific  technology  support system.
