Abstract

This study reports a simple micropropagation protocol and thereby rapid multiplication of the useful medicinal plant- Scoparia dulcis L. Single node explants were inoculated on basal MS medium containing 3% (w/v) sucrose, supplemented with different concentrations and combinations of 6-benzylaminopurine (BAP), kinetin (KN), indole-3-acetic acid (IAA), indole-3-butyric acid (IBA) and Naphthalene acetic acid (NAA) for direct plant regeneration. Maximum numbers of shoot (~22) were observed on the medium containing 0.5 mg/l BAP and 0.25 mg/l IAA after four weeks of culture. Regenerated shoots were separated and ischolar_mained on half strength MS medium supplemented with 0.5 mg/l of IBA alone for three weeks. Simultaneous regeneration of shoots and ischolar_mains and in vitro flowering were achieved from the nodal explants on MS medium supplemented with 0.5 mg/l KN and 2.0 mg/l IAA. Well-developed complete plantlets were transferred on to specially made plastic cup containing soil rite. Acclimatized plantlets were successfully grown in garden soil.

Abstract

Lasiodiplodia theobromae, a fungal pathogen causing stem cankers on Dalbergia sissoo is reported in Haryana and Punjab for the first time. It might have reached to D. sissoo from fruit trees like pear and peaches grown in the area where this fungus was reported earlier. The disease exhibited symptoms like dark spots on the bark with splitting, cankers and oozing of sap. The affected trees showed die back to varying degree. Bavistin was found as the most effective fungicide inhibiting complete growth of the fungus at 100 ppm among other fungicides. Among biological control agents Trichoderma harzianum exhibited distinct antagonism, T. koningii exhibited mycoparasitism, T. viride showed inhibition at the line of contact whereas Aspergillus niger showed overlapping. Spraying with Bavistin or Trucop on stem, branches and twigs of affected trees is recommended for checking the further spread of the disease. Chaubatia paste can also be applied while pruning the trees to check entry of the pathogen.

Abstract

Field pea (Pisum sativum L.) is a good source of dietary protein to complement the cereal based diet, particularly for vegetarian masses in the country. It is a Rabi pulse crop which is highly productive and is grown for food, feed and vegetable. Present study was carried out in different villages (17) and blocks (03) of Sant Ravidas Nagar district. Fifty nine front line demonstrations on Malviya Matar-15, a promising cultivar of field pea developed from B.H.U., Varanasi were conducted during 2011-12 and 2012-13 by KVK, Sant Ravidas Nagar. Appropriate interventions viz., improved variety of seed, balance application of fertilizers, weed control, proper seed rate, sowing methods, plant protection measures were adopted under front line demonstration on field pea. The results revealed that improved variety gave 32.9 and 36.89 per cent higher yield with net income Rs. 38402 and Rs. 46419 per hectare over local check variety 'Rachna' during respective years. However, benefit cost ratio was observed as 2.2 and 2.28 during 2011-12 and 2012-13, respectively. In the line of promotion of such improved technology, extensive field days were organized where the farmers of adjoining villages had seen the impact of improved technology at their own or nearby field. Presently, 48 per cent farmers are growing this variety successfully in adopted villages of KVK. Thus, the results of front line demonstration of field pea clearly indicated that by adoption of appropriate interventions, production and productivity of field pea could be enhanced substantially and providing suitable and sustainable option to farmers of eastern Uttar Pradesh.

Abstract

New Rb-Sr isotopic age is presented for the porphyritic phase of Kanara batholith of South Kanara, Karnataka. The porphyritic granite has a good spread of Rb/Sr ratio and indicates an isochron age of 2681 ± 236 Ma with an initial ratio of 0.7022 ± 0.004. The observed low initial Sr ratio suggests its derivation from mantle without much crustal contamination.

Abstract

A rare mineral Beudantite PbFe₃ (AsO₄)(SO₄)(OH)₆had been identified by X-ray diffraction technique in a weathered mineralised quartz vein, emplaced in phyllitic sequence. Its cell parameters are a=7.32Å. and c=17.13Å that are comparable to those of JCPDS-ASTM standard. Its association with corkite suggests that the area may have potential for silver and gold.

Abstract

Reproductive biomedicine covers all stages of the human lifespan from birth to death. Any kind of imbalance or abnormality in the development, growth and physiology of the reproductive and associated systems causes great physical and psychological discomfort that often results in embarrassment for the individual. Although allopathy provides immense relief and comfort to patients, the costs involved are now becoming prohibitive for the average citizen. This crisis has led us to search for alternate forms of reliable medicine. Herbalism Is one form of ancient folklore medicine that has been neglected and at times brushed aside as witchcraft. However, an increasing awareness and a change of attitude has prompted a re-exploration of the potentials of this practice with a scientific bent of mind. Herbs with safer and more effective ingredients are currently being isolated and tested for use In reproductive biomedicine. The advances in information technology have also made it possible to establish databanks for various kinds of reproductive disorders and to link them with remedies offered by nature's laboratory. In this review we focus on some of the problems related to reproductive health and highlight the variety of herbs that could be used to deal with such situations effectively.

Abstract

Smart-puter is a mini computer designed for the two-wheelers to increase the level of security and control. This is designed with special algorithms such that it will be benefited by both user and the public servants. In this we have a complete digitalization of the vehicle components and make the display on the smart-puter. Smart-puter has the interfacing of displaying petrol and battery levels, lean position, turn indicator, engine temperature, global time, trip levels and the maximum speed set option. This also has a GPS module as well as it has the access to use GPS navigation and a GSM network so that he can always track the vehicle where it is through a particular cell number. This system design is done with the complete concentration over the power usage as well as the cost that plays the major role in the design technology. At the same it the GSM module is even programmed in such a way that if any breakdown of the vehicle occurs then its location where it has occurred is immediately sent as an SMS to the one registered number who always monitors the vehicle. It may be either due to accidents, climate and conditions. To make this task the special sectrol algorithms were designed.
