The organic farmers of the European countries are producing organic potato for the industry. Organic potato raw materials for industrial processing have become a new source of income for them and the demand is increasing. The transition of organic food against the conventionally processed and marketed products is steadily increasing in the Netherlands. Thus, this review is prepared to formulate guidelines for increasing organic processing with the following key parameters such as to identify the limitation with organic processing compared to the conventional, to interpret the quality characteristics of raw materials, to find out the problems and solutions of organic potato processing and to analyze the effect of external and internal factors of organic proc...

Seventy five households were randomly selected and data were collected using structured questionnaires and resulted in the documentation of 87 useful medicinal plant species belonging to 51 families including trees (40%), herbs (32%), shrubs (20%) and climber (8%). The Fabaceae and Zingiberaceae family provided the largest number of species (5 plants) followed by Apocynaceae, Combretaceae and Euphorbiaceae (4 plants from each family). Among the identified plants 80 species uses against human disease, 11 species used against animal disease and 10 species used for pest control. Leaf was used in the majority of cases for medicinal preparation (52 species), followed by fruits (21 species), roots (19 species), seeds (13 species), barks (15 species) and besides these, rhizome, flower, latex as well as whole plant were used. Unfortunately, medicinal plants are increasingly threatened by various environmental, socioeconomic and institutional problems. In the study area some medicinal plant species (Neem, Khejur, Mandar, Ulot kambal, Sazna, Bael and Amloki) were found well adapted for many years. However, proper training with adequate supply of desired medicinal plant species are required and credit facilities would be helpful for large scale cultivation of medicinal plants.

Determination of soil loss required lots of information and data sets from various variables related to RUSLE2 in different formats scales. The effect of each factor affection soil loss and or erosion was estimated. Soil loss was influenced by soil properties (textural class), rainfall, topography (slope gradient), crop management and conservation practices (soil cover, type of tillage). The influence of erosion control practices (up and down slope ploughing, perfect contouring and buffer strip) on soil loss was also analysed. Results indicated that among three textural class of soils highest loss found in the silty soil followed by loamy sand and clayey soil had the least soil loss. This showed that the silty soil had the highest erodibility. It was evident from the modelling that as the slope steepness and slope length increased the soil loss increased, but when the slope steepness and slope length were reduced the soil loss decreased. Soil cover and tillage contributed greatly in soil erosion. The bare soil (silt) had the highest soil loss 22 Mg ha-1 yr-1 but the dense grass cover had the lowest soil loss of 0.034 Mg ha-1 yr-1. While the conventional tillage had higher soil loss 15 Mg ha-1 yr-1 compared with the Original Research Article-1) loss and should be discouraged. These results will be used for soil protection measures and land use planning in agriculture.

Mainly two diseases leaf spot and die-back were diagnosed. Botryodiplodia theobromae and a fungus resembling Curvularia pallescens were associated, respectively with die-back and leaf spot symptoms. Seed treatment (with vitavax 200) @ 0.02%of seed weight, foliar spray (with Dithan-M-45) @ 90 gm/20L water, soil treatment (with 40% Formaldehyde) @ 60m1/2000m1 water/bed were employed either singly or in combination. All the treatments showed significant reduction of disease incidence and severity. However, among these the combined application of seed, soil and foliar spray treatments highly reduced the symptoms of the diseases. The incidence and severity of the diseases influenced positively with the height of the seedling in the nursery. The tallest and the healthiest Jackfruit seedlings were produced in the nursery beds where a combination...

The survey was conducted with a semi-structured questionnaire and data was collected from 60 households (thirty from each) selected consistent with farmers category. From the two villages, we found 72 species under 35 families and 61 genera were used as NCVs round the year though availability increases in winter season. The best contributing family was Araceae (7 species) followed by, Lamiaceae (6), Apiaceae, Asteraceae and Cucurbitaceae (5 species each) then on and rest 22 families with just one species. Dioscorea (4 species) was the best contributing genera followed by Colocasia, Cucumis and Solanum (3 species each), Amaranthus and Pogostemon (2 species each) and rest of genera represent with single species. These vegetables mostly collected from wild (68.1%) by ethnic people for their daily consumption and most of them were herbs (68.1%). 2.8 percent each of the recorded species were endangered, vulnerable and near threatened. Among these vegetables, Cucumis hystrix and Asparagus recemosus endangered (EN) condition. Besides this Cucumis melo and Homalomena aromatica vulnerable while Dioscorea bulbifera and Musa ornate were near threatened. In both locations, small farmers used a bigger diversity of non-conventional vegetables. Not for food quality, NCVs also make a big contribution to the tribal people's nutrition throughout the entire year especially wild NCVs.

Rice was grown in different orientations around the tree of Albida, Akashmoni and Jhau (North, South, East and West orientations), as the orientations were made 1 m apart from the tree base. The effect of tree-rice association was found significant on plant height, effective tillers hill-1 , non-effective tillers hill-1 , effective grains panicle-1 , sterile spikelets panicle-1 , total grain (t ha-1) and straw yield (t ha-1). It was recorded that out of the three tree-rice association, the highest yield (4.88 t ha-1) was found under Albida and the lowest yield (4.70 t ha-1) was found under Akashmoni that was statistically similar with Jhau. The highest (7.10 t ha-1) and lowest (6.80 t ha-1) straw yield were found under Albida and Akashmoni. The highest plant height (105.75 cm), effective tillers hill-1 (11.85), non-effective tillers hill-1 (1.91), effective grains panicle-1 (140.65), and sterile spikelet panicle-1 (29.88) were found under the Albida. Regarding different orientations from the tree base, the plant height, effective tillers hill-1 , noneffective tillers hill-1 , effective grains panicle-1 and grain yield (t ha-1) of rice were significant. The highest grain yield (4.86 t ha-1) of rice was obtained at the north orientation and the lowest grain yield (4.60 t ha-1) of rice was obtained at the west orientation, while significantly highest grain yield (5.00 t ha-1) was found in control. All parameters produced the highest performance in open field compared to tree-rice association in respect of orientation.

A total of 60 households (more than 45% population) in the two enclaves of the locality were surveyed by semi-structured questionnaire. Plant species were collected and preserved in herbarium sheet and were brought to the laboratory for identification consulting Monograph and Taxonomist. A total of thirty six species belonging to thirty four Genera and twenty four families of foliage vegetables found to be utilized by native tribes. Of these, nine were cultivated and nineteen were wild and rests of the eight species were both from wild and cultivated. Considering growth habit, twelve species were annual and twenty four were grown seasonally. Among the species Ajuga macrosperma of Lamiaceae, Cardiospermum halicacabum of Sapindaceae, Chenopodium album of chenopodiaceae, Cissus repens of Vitaceace family were rarely found in the wild. In each of the locations, landless farmer used larger diversity of leafy vegetables. The small farmers of the locality were dependent on the wild vegetables and most of them were available year round. Several leafy vegetables were found to be consumed primarily due to their nutritional values without much concerning health importance. The results of this study showed a remarkable diversity of therapeutically useful foliage vegetables inside the surveyed location. It further indicated the potentials of those plants in enhancing nutrition and health care of average villager's against the face of harsh condition. It further indicated the demand for concern on the conservation of these leafy vegetables (especially those in wild) is stressed so as to safeguard them for future generation and avoid their genetic erosion.

Data were collected from the selected respondents by using structured questionnaires during September to October 2004. About 90 useful medicinal species were identified; among them 30 were tree species, 29 shrubs and 31 herbs. The prevalent tree species with medicinal value in the study area were Amloki (3.20), Neem (3.13), Nishinda (2.66), Kharajora (2.56), Sheora (2.01), Arjun (1.92), Chalta (1.87) etc. Most prevalent medicinal shrub species were Cassava (4.56) followed by Bashak (2.09), Akanda (1.98), Papaya (1.67), Dhalim (1.12) etc. and most prevalent medicinal hurb species were Vat (23.80), Bonhalud (13.67), Patharkuchi (6.41), Apung (6.30), Lajjabati (4.81), Pumonava (4.74) etc. Economically potential species were Arjun, Amloki, Horitaki, Ulotkombal, Ghritakanchan etc. The relationship between socioeconomic condition with selected characteristics such as age and homestead area was found insignificant; while the rest characteristics like education level, family size, farm size, overall annual income, income from medicinal plants, knowledge on medicinal plants, preference towards medicinal plants of the respondents were found statistically significant which motivated them to raise the medicinal plant species in their homestead area. From the socioeconomic point of view, medicinal plants provided a critical source of income for many rural communities, especially landless poor and marginalized farmers. The plant species having high commercial value may be utilized as a source of income for the rural farmers. It was noticed that the respondents reduced health care cost by using this indigenous trees, shrubs and herbs. Moreover, the people who took kavirazi as a profession and contributed in rural health care were well known and given higher respect from the society. Unfortunately, medicinal plants are increasingly threatened by various environmental, socioeconomic and institutional problems. Most of the respondents opined that their problems were mainly related to lack of land, time, inputs, proper knowledge, economic support and unwillingness to cultivate and conserve medicinal plants. However, proper training with adequate supply of desired medicinal plant species are required and credit facilities would be helpful for large scale cultivation of medicinal plants.

T... more Area coverage, production and yield of potato have increased in last few decades in Bangladesh. The average yield of potato is 18.08 t/ha. Its production can be increased up to 30-40 t/ha using high yielding varieties and improved production technology. Tuber Crop research Centre (TCRC) of BARI has so far developed 44 potato varieties which were selected from exotic varieties, foreign germplasm and germplasm developed in Bangladesh by introducing and crossing programme. The formal seed potato produced less than 10% seeds of the total requirement. But the supply of quality seeds through formal system is remarkably increasing. The seeds supplying through informal system is not recognized to be quality seeds because in the informal system seeds are not produced by following the steps of seed technology, rather tubers for food are used as seeds. The formal sector seed potato production is only 5-9% of the total requirement. The use of these poor quality seed is one of the major factors ...
