Molecular detection and characterization of African swine fever virus from field outbreaks in domestic pigs, Mizoram, India.

Abstract: African swine fever (ASF) is a devastating haemorrhagic disease of domestic pigs, which can cause mortality up to 100%. Sudden mortality in pigs following an acute course of systemic disease was investigated in Mizoram state of India and confirmed the outbreak as ASF. Affected pigs suffered from severe depression, high fever, bloody diarrhoea, cutaneous haemorrhages and showed haemorrhagic lesions in visceral organs. The outbreak was confirmed by detection of p72, p54 and the central variable region of B602L genes by PCR in representative tissue samples collected from dead pigs. The nucleotide and phylogenetic analyses of p72, p54 and B602L characterized the ASFV as genotype II. Interestingly, the analysis of B602L gene has revealed that the ASFV from Mizoram state of India is more closely linked to the Eurasian ASFV strains isolated prior to 2014 and discriminated the Indian strains in two separate groups indicating that the source of origin for the Mizoram outbreak could be different from that of the other states of India.

Phytochemical Analysis of Ocimum Spp. - An Important Medicinal Plant

Abstract: The antioxidant activities of four genotypes of basil species were selected for biochemical studies, viz., Ocimum sanctum L. (Rama Tulsi), Ocimum tenuiflorum L. (Krishna Tulsi), Ocimum gratissimum L. (Van Tulsi), and Ocimum basilicum L. (Babui Tulsi) for the antioxidant properties. Ocimum L. is considered useful in the treatment of respiratory system disorders, reduction of blood glucose level and is regarded as an 'adaptogen' or anti-stress agent. The phytochemical analysis of the plant leaves extract to the estimation of standard biochemical methods such as peroxidase, superoxide dismutase (SOD), polyphenol oxidase (PPO), catalase activity, antioxidant, flavonoids, total phenols, protein as well as total carbohydrates, starch and reducing and non-reducing sugar. The biochemical studies revealed that the starch (98 mg/gfw), the content was found to be higher in O. gratissimum. Similarly the other parameters such as total sugar (159 mg/gfw), non-reducing sugar (61mg/gfw), Peroxidase (142 U/mL), Catalase (188 U/mL), SOD (92.47 U/mL), PPO (462 U/mL) were found to be higher in O. sanctum. On the other hand, soluble protein (62 mg/gfw), total flavonoids (325 mg/gfw) and total flavonols (486 mg/gfw) were found to be higher in O. tenuiflorum. Total antioxidants (136.45 mg/gfw), reducing sugar (108 mg/gfw) and phenol (479 mg/gfw) were found to be higher in O. basilicum. The result shows that the best genotype among the four follows the trends O. sanctum > O. basilicum > O. tenuiflorum > O. gratissimum. On the basis of the result, the two genotypes can be recommended for medicinal purpose in the pharmaceutical application.

Investigation on effect of time of planting in cucumber (Cucumis sativus L.) under polyhouse conditions in Manipur, India

Abstract: An experiment on the standardization of time of planting for growing cucumber(Cucumis sativus L.) inside polyhouse was conducted during 2010-11 at the Horticutural Experimental Field, College of Agriculture, Central Agricultural University, Imphal (Manipur), India. The experiment comprised of four dates of planting (September, October, November and December) and two cucumber varieties viz.Alamgir CT 280 and Alamgir CT 380, in Factori-al Randomised Block Design with three replications and eight treatments.Impact of time of planting was established on vegetative characters; flowering and fruiting characters; yield and yielding attributes. Effect of different time of planting and variety on growth of cucumber was found to produce significant effect (at 5% level of probability) on main vine length, numbers of leaves per plant and leaf area. For both the varieties, September planting gave maxi-mum values of main vine length (221.93 cm and 240.51 cm, respectively), number of leaves per plant (21.21 and 21.92, respectively) and leaf area (393.26 cm2 and 413.76 cm2, respectively). The treatment combination of Septem-ber planting with Alamgir CT 280 gave shorter number of days (12.6) from fruit set to maturity. The different time of planting and varieties and their interactions showed significant effect on number of fruits per plant, fruit length (cm), fruit diameter (cm), single fruit weight (g), fruit yield/plant (kg) and fruit yield/ha (t). The results revealed that the treatment combination of September planting with Alamgir CT 380 gave the highest yield (47.31t/ha), as compared with October, November and December plantings. However, the maximum cost- benefit ratio (1: 2.24) was found in October planting. The present study suggests that cucumber can be grown successfully during winter months under polyhouse in Manipur, India condition.

Influence of Legumes and their Planting Geometry as Intercrop with Potato ( Solanum tuberosum L.) on Productivityand Soil N Fertility

Abstract: Peas, gram and broad bean were tried as intercrops in potato for two seasons. The results revealed that potato + gram intercropping in 2:1 and 1:1 row ratio combinations produced higher yield over potato sole cropping. Higher uptake of N was also observed in the said intercropping systems in comparison to that of potato sole. Inspite of higher N uptake, better N soil balance were observed in these intercropping systems as indicated by positive soil N balance while that of potato sole cropping showed a negative balance.

A Note on Indian Agricultural System Vis-À-Vis ATMA Model

Abstract: During the past 60 years, the Indian extension system has evolved to reflect national priorities. At the same time, malnutrition and poverty continue to be persistent problems for the rural poor. The major issues before Indian extension system are: how to improve the effectiveness of extension systems? How to serve the small land holders and marginal farmers in diversified farming systems, and proper allocation of funds, human resources and its management? The World Bank funded Innovations in Technology Dissemination (ITD) component of National Agricultural Technology Project (NATP) focused on bottom-up planning process for technology assessment, refinement and dissemination in order to make the whole extension system demand-driven and farmer accountable. This has helped to strengthen research and extension capabilities, restructure public extension services and test new institutional arrangements for technology transfer with the involvement of all the stakeholders of Government and Non-Government agencies at the district level.
