Abstract: Rising of rice seedlings is among the important factors responsible for better growth and development of rice plants as well as increasing the grain yield. Conventional method of raising rice seedlings requires larger space, time (24 hours seed soaking and 34 hours in jute bag up to sprouting) and labour intensive procedure, which limits the production capacity of rice seedlings. Transplanted seedlings raised by newly developed single seedling nursery tray have not been compared with the conventional system in the field so far. The objective of this study was to evaluate the average number of tillers per hill at 60-days after transplanting (DAT). The experimental design was one treatment [newly developed single seedling nursery tray (T1)] and three replications. The age of the seedlings raised by the newly developed single seedling nursery tray at the time of transplantation was 8 days. Plants were randomly selected and number of tillers were counted and recorded at 60 DAT from each treatment plot for further analysis. Average number of tillers (32.27 tillers/hill) in the case of the conventional system at 60 DAT using 8 days old seedlings was collected from previously published data. One sample T test was used to analyse the data using SPSS statistical analysis software (version 21) at 95% Confidence Levelof the Difference. The result of the analysis showed significant difference between them, with larger average number of tillers in T1 (68.56 tillers/hill) than the existing average number of tillers. The study depicted that using the newly developed single seedling nursery tray is one of the options to increase the number of tillers in SRI farming in order to increase the number of effective tillers, number of panicles, straw yield and grain yield of rice plants.

Abstract: In spite of being the leading producer of mango in the world, India registers the highest post harvest losses and minuscule exports. The reasons for this paradox are manifold. However, issues related to quarantine, shelf life and quality are the major stumbling blocks to trade, both national and international Therefore, a balance between the required effective dose and tolerance of fruit to irradiation has to be investigated under various storage temperatures. The experiment was arranged with sixteen treatment combinations of irradiation doses (0.00kGy-0.60kGy) and similar to storage temperature (Ambient at 27±2°C and 60-70% RH, 9°C and 90% RH, 12°C and 90% RH and Control atmospheric (CA) storage (12°C, O2 2%, CO2 3% and RH 90%) from the year 2008-2010. The fruits were exposed to gamma radiation from the source of 60Co. The data indicated that the fruits irradiated with 0.40kGy gamma rays recorded significantly minimum per cent reduction in physiological loss in weight, reduced ripening per cent, increased marketability of fruits and maximum average days to ripening and shelf life of fruits. Similar pattern were noticed when fruits kept at 9°C storage temperature and in combined effect of irradiation and storage conditions. Suggestions are made for maximizing storage potential by use of irradiation and adequate storage facilities for qualitative and hygiene produces.

Abstract: The study was conducted at the farm of Sher-e-Bangla Agricultural University, Dhaka during the period from April to December 2012 to determine the incidence of spider mites on different variety of roses. The experiment included twelve varieties of roses viz. Wild rose, Crazy love bi-color, Yellow star, Missing love, Compassion, Charming lady, Dream bangle, Sleepy moon, Sweet doll, Moon light, Sweet love and Mini moni. Each variety represents as one treatment. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Incidence of spider mites showed significant variation due to the effect of varieties. Among the varieties, Sweet Love was tolerant of pests and the lowest number of spider mites were recorded at vegetative and flowering stages. Varieties of rose significantly influenced the incidence of pests as well as growth characteristics of rose indicating lowest number of infested leaves per plant, lowest number of infested branch per plant and lowest number of infested flower per plant on Sweet Love variety. Sweet Love variety showed tolerant to spider mites of rose and gave better yield among the all varietal treatments while sweet doll variety graded as susceptible mites due to the lowest performance regarding pest incidence and infestation.

Abstract: The Cucurbitaceae family commonly known as the gourd family is an excellent example of a plant family with many economically useful species. They are native in most countries of the world, especially in the tropics, where they are cultivated in every country, state, and province. The Cucurbitaceae consists of many important food plants such as melon, pumpkin, squash, cucumber; useful plants for the production of items of utility such as bottle gourds, loofah, ornamental gourds, etc. Some species, example, bitter melon, cucumber, musk melon, etc are considered to have medicinal properties due to the presence of cucurbitacins, etc. Others such as Luffa, Cucurbita, etc are used as complementary dietary ingredient of feed for poultry and increasingly as a protein and vitamin supplement to aqua feeds. Members of this family such as Momordica, Cucurbita, Cucumis etc are also used as remedies for livestock. In addition, seed oil of melon is a source of biodiesel. This article briefly reviews the nutritional, medicinal, ethnoveterinary and ethnomedicinal value of these plants, as well as their uses as items of utility, complementary dietary ingredient for poultry and aquafeed and as a source of biodiesel. This is an attempt to compile and document information on the different uses of these plants and to recommend that increased in production of these plants will be profitable and will contribute to food security and livelihood sustainability in Nigeria.

Abstract: Background: The flowering plants have a number of uses as food, specifically as grains, sugars, vegetables, fruits, oils, nuts, and spices. In addition, plants and their products serve a number of other needs, such as dyes, fibers, timber, fuel, medicines, and ornamentals. The contribution of the angiosperms to biodiversity and habitat is so extremely important that human life is totally dependent on it. Materials and Methods: Angiosperm diversity at village Sabgram of Bogra district, Bangladesh conducted during March 2013 to July 2014. All the species were noted and time to time the areas were visited to see when they flowered. For the morphological study, different types of species were examined again and again in order to see if there was any variation or not. They were collected at flowering stages and herbarium specimens were prepared as vouchers. In this practice standard method was followed. Results: A total of 196 species belonging to 160 genera under 69 families were recorded. One hundred nineteen (119) medicinal plants have been recorded with their uses for the cure of more than 87 diseases, and some of these are skin disease, diarrhea, dysentery, fever, earache, piles, inflammations, rheumatism, dyspepsia, constipation, diabetes, kidney disease, bronchitis, ulcers, anemia, asthma, ringworm, herpes, jaundice, headache, opthalmia, cough, eye disease leprosy, menstrual disease and others. Conclusion: The present study was made an inventory of the angiosperm diversity in the study area and documentation of long-established knowledge on the medicinal uses of these plants is essential for conservation efforts for the plants resources and new drug development.

Abstract: Pollen analysis, a technique for identifying pollen grains and hence the plant taxa visited by bees, is a means of clarifying the floral origin of honey. The objective of this study is to determine the pollen composition of the supposed honey of Dialium guineensis Willd to verify the geographical and botanical origins given by the beekeepers. The pollen analysis of the supposed honeys of Dialium guineensis was carried out according by authors. The identification and enumeration of the pollen was done under the microscope. Pollens are usually classified according to the four categories proposed by authors according to the value of the relative frequency (R F): dominant pollen whose frequency > 45%; accompanying pollen; 16 ≤ frequency ≤ 45%; Important isolated pollen; 3 ≤ frequency ≤ 15% pollen isolated when frequency < to 3%. A total of 14 taxa divided into 7 families were identified. Depending on the maximum FR value reached, the dominant taxa are Elaeis guineensis with a RF of 74.04% and Avicennia sp with 46.67%. The largest RF found for Dialium guineensis is 14.56%. The nectariferous taxa represent 45.45%, the nectariferous and polliniferous taxa 36.36% and the polliniferous taxa 18.18%. The Dialium guineensis is nectariferous but is not dominant in any of the samples. As for Elaeis guineensis, it is dominant in a single sample but cannot determine the botanical origin because it is a polliniferous plant. The botanical origin is determined by the nectarifer taxon hence the name of honey. The honey name of Dialium is not appropriate because the taxon is either isolated or isolated important. However we have honey from Avicennia sp or mangrove honey whose taxon is nectariferous and dominant in one of the samples.
