Characterization of Mineral Phosphate Solubilizing  Gram-positive Bacteria

Most agronomic soils contain large reserves of total phosphorus [P], but the fixation and precipitation of P cause P deficiency, and in turn, restrict the growth of crops severely. Phosphorus replenishment, especially in sustainable production systems, remains a major challenge as it is mainly fertilizerdependent. Though the use of chemical P fertilizers is obviously the best means to circumvent P deficiency in different agroecosystems, their use is always limited due to its spiralling cost. A greater interest has, therefore, been generated to find an alternative yet inexpensive technology that could provide sufficient P to plants while reducing the dependence on expensive chemical P fertilizers. Among the heterogeneous and naturally abundant microbes inhabiting the rhizosphere, the phosphate solubilizing microorganisms (PSM) including bacteria have provided an alternative biotechnological solution in sustainable agriculture to meet the P demands of plants.

Influence of Mineral Phosphate Solubilizing Grampositive Bacteria on Growth and Yield of Cowpea (Vig

A pot experiment was conducted in glass house conditions for 120 days to study the effects of phosphorus solubilizing Gram-positive bacteria on plant growth, nutrient uptake and yield of cowpea (Vigna unguculata). Among all twelve bacterial treatments, the strain Bacillus spp (B3) has shown the greatest shoot length 67.70 cm, root length 60.5 cm and total dry weight 4.57 g plant -1 after 45 days of sowing. Similarly, in the same treatment the shoot length, root length and total dry weight were found 162.36 cm, 60.5 cm and 128.49 g plant -1 , respectively at harvesting and total yield was obtained 23.34 g plant -1 , which was significantly greater than all other treatments and uninoculated control treatments containing single super phosphate (SSP) and rock phosphate (RP) as phosphorus sources (7.93 g plant -1 and 3.81 g plant -1 respectively). The strains Bacillus thurengensis (T1 and T6) also have indicated a significant increase in above parameters

Promoting Functional Teacher Education in Nigeria:  Problems and Prospects

It is an undisputable fact that no education style can rise above the quality of its teachers. Teacher education advancement will determine the position of the country in the comity of nations. Hence, the nation’s development can only be enhanced by the quality of education given to her citizens. This paper therefore, discusses the meaning of teacher education, historical development of teacher education in Nigeria, present position of teacher education, relevance of teacher education, aims of teacher education, problems militating against teacher education in the country and various strategies taken by the government to promote the growth and development of teacher education in Nigeria examined

Effect of Mine Tailings on the Growth of Ornamental  Plants

The researchers sought to determine the effect of mine tailings on the growth ornamental plants. The study aimed to evaluate the effects of mine tailings o n the numbers of seed germinated, number of leaves, length of seedlings and length of primary roots; assess the effects of the various percentages of mine tailings; determine the interaction effect of the various percentages of mine tailings with fertile soil and organic fertilizers; and establish the best kind of percentages of mine tailings on the germination of seeds and growth of seedlings. Experiments were performed to determine the germination and growth of petunia seeds. Selections of plant candidate from varieties of seeds were considered. The ideal candidate is petunia seeds since it can sprout at a minimum period of seven days. Generally, there is significant effect of mine tailing concentration in primary root growth .

Response of UV-B Radiation on Germination Percentage,  Growth Pattern and Chlorophyll Content at see

Capsicum annum L. (Syn: Capsicum frutescens L., family: Solanaceae) is an herbaceous spice plant cultivated in tropical and subtropical conditions in different countries of the world. In India it is commonly known as “Lal Mirch”. The present study deals with response of UV-B radiation on different growth parameters of capsicum crop. Plants were grown in the field and exposed to supplemental UV-B radiation (280-320nm) for 1 hr and 3hr regularly supplied by the sunlamp, 300 watt from sowing till seedling stage. The total UV-B irradiation received by the plants from the lamp was 24.23 Jm -2 s -1 . The seed germination percentage was significantly decreased by 1 hr and 3 hr UV-B irradiation. The exposure of 1 hr UV-B irradiation showed promotory response on chlorophyll content and biomass of plumule and cotyledons while exposure of 3 hr of UV-B irradiation showed inhibitory effect on growth and chlorophyll content of seedlings. Current findings suggest ways to increase crop

Effect of Force Control during Spot Welding on Weld  Properties

Resistance Spot Welding (RSW) is a process that is widely used in the automotive industries. The parameters that are used to develop a spot weld are the welding current, weld time and electrode force. Electrode force was not used as a control parameter due to the use of pneumatic system to actuate the welding electrode. The pneumatic system does not allow the development of closed loop control system; therefore electrode force was not used to control the growth of the spot weld nugget. This reported work looks into the ability to control electrode force dynamically during welding by using servomechanism. Force profiles were introduced in this work and the electrode force during welding was controlled to follow these force profiles. Based on the findings, the developed controller was able to control the electrode force during welding to follow the given force profiles. Decreasing the electrode force during welding facilitates the initiation of spot weld growth earlier in

Comparisons of Bioactive Compounds in Different  Cultivars of Turmeric Grown in Eastern U.P.

- The present investigation was carried out at field trail of Main Experimental Station, Vegetable Science N.D.U.A. & T., Kumarganj, Faizabad (U.P.) during 2011-12 to study the performance of turmeric cultivars. Cultivar NDH-7 and NDH-8 was found superior in growth characteristics such as plant height, yield of rhizome/plant. NDH-8 found tallest (111.2 cm) while, yield of rhizome per plant was recorded in NDH-7 (303.00 g). The results showed that moisture, mineral, curcumin and essential oil ranged from 9.4 to 12.2 per cent, 3.39 to 5.30 per cent, 3.7 to 5.9 per cent and 3.32 to 8.19 per cent, respectively. NDH-7, NDH-8 and Prahba were found superior among all cultivars and variety.
