The stusy was conducted at Binuria village in Birbhum District of West Bengal during February to October (2013). The village is in close vicinity of Visva Bharati University, Santiniketan. The study area lies in 23.660 N and 87.630E at about 179 ft. above MSL, with level to nearly level landscape. The experiment was laid down as per randomized block design (RBD) with 7 treatments replicated 3 times. The treatments included local farming practice with chemical inputs, organic farming practice (Inhana Rational Farming (IRF) Technology’ developed by Dr. P. Das Biswas, Founder, Inhana Biosciences, Kolkata) as well as integrated farming practice (combination of chemical and organic inputs for both soil and plant management). The most significant finding was that 100% reduction of chemical...

Present study at Maud tea estate (Assam), India under FAO-CFC-TBI Project (2009 – 2013) was aimed for formulation of Soil Development Index (SDI) to evaluate the comparative soil quality enhancement under organic soil management through different types of compost viz. vermicompost, Indigenous (FYM), Biodynamic and Novcom compost along with their respective crop performance. The result showed superiority of Novcom compost over others in terms of total NPK percent (4.25 %), total microbial population (10 3 to 10 6 times higher c.f.u. per gm moist compost) and germination index (17.5 % higher than 2 nd best value). Application of compost for 3 consecutive years to supply 60 kg N caused an overall increase in the value of soil quality parameters viz. organic carbon (19.4 to 41.4 %), available nutrient (i.e. NPK...

The present study was conducted in three villages through Naopara, Kantia and Syamsundarpur in the Barddhaman district of West Bengal; to explore the potentials of integrating other field crops in the existing rice based cropping system towards improving the monetary productivity and farmers’ livelihood. Field experiments were conducted taking different cropping systems through rice–rice, rice–potato–black gram, rice–potato–sesame and rice–mustard–black gram in four soil series i.e., Syamsundarpur I, Syamsundarpur II, Naopara and Kantia as developed on gently sloping alluvial plan. Soils varied in texture (loamy to clay), organic carbon content (4.4 to 9.8 gkg -1 ), cation exchange capacity (10.0 to 22.4 cmol (p+)kg -1 ) and pH (5.3 to 6.4). Soil fertility status indicates low to medium N (245 to 345 kgha -1 ), medium to high P 2 O 5 (70 to 110 kgha -1 ) and medium to high K 2 O (162 ...

Novcom composting method was tried out for effective biodegradation of water hyacinth in Krishi Vigyan Kendra, Howrah, West Bengal during January to February, 2014 and the results showed a good quality mature compost can be obtained within 21 days. The analytical results showed qualitative aspects of Novcom compost in terms of total NPK content (4.18 %), total microbial count (in the order of 1014 to 1016 c.f.u.) and germination index (> 1.0 which it confirmed that the compost enhanced rather than impaired germination and radical growth) as also substantiated by the high compost quality index. Absence of any infrastructural requirement for composting, speedy biodegradation period (21 days), high end product quality indicated the potential of Novcom Composting Method towards large scale adoption among farmer’s level

Comparative nutrient content in terms of N + P205 + K20 was highest in Novcom compost (3.98 %) followed by Biodynamic (3.56 %), Vermi (3.16 %) and Indigenous (2.96 %) compost. But comparative evaluation of microbial population (total bacteria, fungi, actinomycetes, ammonifiers, nitrifiers and phosphate solubilizing bacteria) in all the compost samples revealed distinctly different status of Novcom compost as compared to the rest. In case of vermi, Biodynamic and Indigenous compost, microbial population varied between 107 to 1012 c.f.u. where as that of Novcom compost varied from 1012 to 1016 c.f.u. The comparatively high microflora population in Novcom compost could be due to its intense biodegradation process, which led to their natural generation wi...

Das B iswas as an effective and economic organic package of practice was evaluated at Farmers’ field in the red laterite zone of West Bengal taking tomato (Solanum lycopersicum) as the test crop. The experiment was laid down as per rand omized block design (RBD) with 7 treatments replicated 4 t imes. The treatments included local farming practic e with chemical inputs and IRF technology with varying dos e of compost. Yield under IRF Package (compost @ 4 ton/ bigha and 10 rounds spraying of solutions for plant management under IRF) was 19.8 percent higher than that of chemical practice. Post harvest analysis of soil sa mples indicated an increasing trend of soil fertili ty especially in terms of soil microbial population, in the Novcom c ompost treated plots as compared to ones receiving chemical treatment.

Compost quality parameters viz. pH (7.98 – 8.09), organic carbon (27.06 – 33.78 %), total NPK (3.58 – 4.75 %), CO2 evolution rate (1.93 – 2.58 mgCO2–C/g OM/day) and germination index (0.95 -1.39) were evaluated following Indian and US compost quality standards. Compost produced in the three different tea estates were found to be of good and extremely good quality as indicated by their Quality Index (CQI). Post application of compost an increasing trend of soil quality especially in terms of soil microbial population was noticed in all the three tea estates. Assessment of the degree of soil development in these tea estates in terms of Soil Development Index (SDI) indicated positive influence of compost application on soil quality irrespective of type of management practice undertaken.

And to bring about the necessary changes, reduction of synthetic fertilizers and higher emphasis on organic soil management is essential. However, meeting the objective on wider scale is an uphill task considering that the present biodegradation methods offer limited choice of raw materials that can be used for compost production. A study was taken up to evaluate the end product quality produced under Novcom composting method using wheat flour mill waste as raw material. Analytical data indicated maturity of Novcom compost within a period of 21 days. Favourable C:N ratio (16:1) along with high nutrient content in terms of total N (1.41%), total P 2 O 5 (0.64%) and total K 2 O (1.21%) indicated high mineralization potential of organic matter for meeting plants’ nutritional requirements, post soil application. Microbial population (per gm moist compost) was noted up to a high order of 10 16 c.f.u. Proliferatio...

Despite West Bengal being one of the leading milk producing states in India, the associated bottlenecks need to be identified and solved in time so that further progress in dairy farming is not hindered. The present study in the Damodar command area of District Barddhaman, West Bengal, one of the intensive agricultural zones; was done to identify the social, socio-economical, feeding, livestock management, breading, healthcare and marketing related constrains as perceived by the common dairy farmers in this region. And non-availability of pasture land, repeat breading problem and non-availability of artificial insemination (AI) centers, distress sell, non-remunerative price of milk and lack of proper training; were identified as some of the major limiting factors in the area. The study indicated...
