The patterns of nomenclature, conservation and traditional uses of mango (Mangifera indica L.) trees and fruits were studied in four districts of eastern Uttar Pradesh (Jaunpur, Azamgarh, Sultanpur and Faizabad), which have preponderance of mango groves consisting of landraces. An explanatory (qualitative) research design, supported by participatory research tools, was adopted to collect the data. The study specifically focused on the role of Indigenous knowledge in the sustainable management of mango groves, which have played a crucial role in livelihood adaptations in the past. It emerged from the data that present day mango groves were planted by the forefathers of present generations who believed in the philosophy of “aadhi kheti, aadhi baari“ which literally means ‘half the crop lands and half the gardens'. This philosophy, based on premise that half the area of a village ecosystems should be cultivated to produce food grains while another half should be under tree plantations to ensure provisioning of fruits, fuel wood, timber and environmental services, was driven by an integrated and sustainable farming approach based on local resources and traditional knowledge. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

The present study was conducted on feeding behaviour and daily activities of rhinoceros (Rhinoceros unicornis)in natural (Pobitora Wildlife Sanctuary, Assam) and captive (Assam state zoo, Guwahati) condition. The observations were made in both day and night time.The study revealed that the rhinoceros spent maximum time in grazing both on grassland (30.14 per cent) and wetland (21.73 per cent). They were observed to be top grazer and preferred to graze slowly in grassland. Early morning and afternoon were most suitable time for grazing for them.Wallowing, galloping, easy walking, standing, resting, and sleeping were some other myriad behaviour that can be seen while watching the rhino in day and night time in natural condition. In comparison to the natural condition, the rhino in the captive condition wallowed for less time (6 per cent) and sleeping (50 per cent) was primary activities of rhinos in the night time. It was observed that rhino maintained good relation with other animals during grazing in both natural and captive condition. Season had effect on the behaviour of rhino specially on grazing and wallowingwhere theanimals spent more time in grazing during post monsoon season than the pre monsoon, monsoon and winter seasons. Highest per cent of wallowing was in the monsoon season (46%) as compared to the pre monsoon (14%). Rhinos had tendency to defecate in a particular place for a long time making a huge dung pile both in natural and captive conditions. © 2015 Agricultural Research Communication Centre.

A study has been carried out to compare status of SPM level in 2002 and 2014 in outdoor air of rural areas of Jammu, so as to evaluate increasing or decreasing trends of change in SPM level. The analysis of data has revealed that all the seven sites of rural areas of Jammu has exhibited significantly (p < 0.05) rise in the values of SPM during the period of 12 years, i.e from 2002 to 2014. Increase in outdoor SPM can be attributed to the increase in number of vehicles, increase in traffic flow rate, increase in number of brick kilns, stone crushers, increase in agricultural processes, increase in industrial processes and domestic heating. © EM International Printed in India.

A field experiment was conducted on heavy clay-loam soil during rabi 2006-07 and 2007-08 at Bundi, Rajasthan with 3 tillage practices (viz Farmer's, conventional and zero tillage) in main plots and 4 N split application (viz 0:80:40, 20:50:50, 40:40:40 and 60:60:0) in sub-plots replicated 8 times. Results showed that zero tillage-sown wheat recorded significantly higher plant height, spikes/m row, effective tillers/plant, test weight, grain and straw yields, net returns, organic C and available N in the soil over farmer's practice and conventional tillage. Zero tillage significantly resulted 7.47 and 7.20% higher grain yield over farmer's practice and conventional tillage on mean basis. The lowest bulk density (1.38 Mg/m3) was recorded under conventional as well as farmer's practice. Split application of N in 3 times (40:40:40) produced significantly higher spikes/m row, effective tillers/plant, test weight, grain and straw yields and net returns over N in 2 splits (0:80:40) but statistically at par with 20:50:50 and 60:60:0. The maximum available N (272.25 kg/ha), net returns (Rs 30 958/ha) and B: C ratio was recorded in 3 N split (40:40:40) application and lowest in 2 N split (80:40:0). Source

Calamus tenuis (Roxb.), a versatile, dioecious rattan species predominant in northeast India, has emerged as an economical material for light furniture and cottage industries. For the genetic improvement of the species, it is essential to be able to recognize male and female plants at the seedling stage. Screening of genomic DNA with inter-simple sequence repeat (ISSR) primers was used to discover sex-specific polymerase chain reaction (PCR) amplification products. Thirty ISSR primers were screened on female and male C. tenuis plants from five different provinces of Assam, India. A putative female-specific marker was identified. The applicability of ISSR-PCR analysis for development of sex-linked molecular markers in Calamus is discussed. © 2010 Springer Science+Business Media B.V. Source
