Item ASSESSMENT OF MAJOR CHEMICAL CONSTITUENTS OF SALINE SOIL OF GRFAATER KHULNA DISTRICT(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University., 2010-12) HAQUE, MD. AINULThe experiment was conducted to assess the major chemical constitunLs of saline soil. A typical saline area of Bangladesh namely Khulna (J)omoria and Ratiaghata lipazil ) , Bagherhat (Sadar and Rampal upazila) and Satkhira (Samnagar and Kaligonj upazila) districts were selected. Four villages from each upazila were selccted. The surlhce soil of 0 to 15 cm were collccted from 24 village of saline zone of greater Khulna district during the period from February to March 2010. The chemical analyses of soil constituents include total nitrogen, available phosphorus and sulphur, exchangeable ions of Na K , Ca'-t Mg2' and Cl and chemical properties such as pH, PC, SSP and SAR were determined and recorded. The pH and PC of all these soil samples varies from 4.82 to 7.56 mhos cm and 1.20 to 5.35 dSnf expressing acid to slightly alkaline and non saline to moderately saline in nature respectively. I'otal nitrogen ranged from .01 to 0.15 % at Madardia of Rampal upazila and Soondarmohal village of l3atiaghata upazila respectively. The available sulphur and phosphorus were recorded as 0.13 to 0.86 and 16.52 to 55.23 m.e/l00 g soil respectively.The dominant exchangeable cations and anion were Na', Ca2' Me, Cl' and K4 . The range of these ions were found as 1.93 to 14.13, 4.68 to 14.56, 3.03 to 5.85, 1.73 to 4.72, 0.13 to 0.60 m.e/100 g soils respectively over 24 villages of greater Khulna district. The SAR of the soil of these villages were recorded from 0.90 to 5.93 which were very sensitive to crops. The SSP of the soil samples ranged from 19 to 56%. The soils of these village were permissible to good for cultivation. The soil of I3hagmari, Noornagar and Hajipur villages were acidic, the soil of Shanpara, Ashan-Nagar, Chatchotia. Dulibola, Palit-Katti. Dakkin-Kooltali and Kooltali villages were slightly acidic, the soil of Radha-Ballop, Cioojiati, Katoora, Deema, BadraSannashi, Suto-Sannashi, Mollikaerbeard, Soondarmohal, and Kodla village were particularly neutral and the soil of Madardia village was slightly alkaly in nature.Item PROXIMATE NUTRIENT CONTENTS IN SOME SELECTED VEGETABLES(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University., 2010-06) UDDIN, MD.HELALThe present study was considered to investigate the nutritional quality of fifteen leafs' and fruit vegetables grown in Bangladesh. The experiment was done on fifteen vegetables viz. Arnaranthus gangeticus (Lalshak)). Atnaranthus lividus (Danta). Rap/ian us sativus (Mulashak)). Momordica charantia (Karola), Trichosant/zes dioica (Potal). Solanuin tuberosurn (Alu). Lablab niger (Sheem), Dacus carota (Carrot). Lycopers icon esculent urn (Green and ripe tomato), Brass icc oleracea var botrytis (Phulkopi). Brassica oleracea var cap/twa (Bandhakopi). Raphanus sativus (Mula) and chenopodiurn a1bun (Goose foot) and Arnrul leaf. The experiment was laid out in a single factor contpletely randomized design with three replications. The vegetables were collected from local markets of Dhaka city. Observations were made on nutritional quality characters like the contents of protein, fat, carbohydrate and minerals in the target vegetables. There was significant variation among the vegetables in respect of all the quality characters such as protein, fat, carbohydrate and mineral content. Results revealed that protein and fat content was greater in lea' vegetables than fruit vegetables. The higher moisture with less protein and fat content were recorded in case of fruit vegetables like Karola and Potal; Karola being the lowest in protein and fat 1.11 and 0.07% respectively. These results indicate that potato and radish contributes less to fulfill our nutritional requirement. The highest iron (4.33%) with higher protein (3.73%) content was recorded for Bothua. The highest fat (0.77%) with higher calcium (2 16%) content was found in country bean. Results revealed that in general, calcium, iron, and other mineral contents were greater in lea' vegetables than root and fruit vegetables except carrot. The highest iron and highest mineral content were recorded in Bothua followed by amrul leaves. The highest calcium with higher mineral content was found in country bean. Country bean, carrot, amrul and bothua stand out to be a good source for protein, fat, calcium, iron and minerals. Therefore, when measures are taken to improve food and nutrition security, there should be a focus on the production and consumption of lalshak. datashak and mulashak. Country bean, carrot. amrul and bothua.Item THE EFFECT OF UREA ON THE YIELD AND PROTEIN CONTENT OF TWO CULT!VARS OF MUNGREAN(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University., 2010-06) HABIB, MD.
