Role of Ni-Mn hybridization in magnetism of martensitic state of Ni-Mn-In shape memory alloys
Extended X-ray Absorption Fine Structure (EXAFS) studies on
NiMnIn have been carried out at Ni and Mn K edge as a
function of temperature. Thermal evolution of nearest neighbor Ni-Mn and Mn-Mn
bond distances in the martensitic phase give a clear evidence of a close
relation between structural and magnetic degrees of freedom in these alloys. In
particular, the study highlights the role of Ni 3d - Mn 3d hybridization in the
magnetism of martensitic phase of these alloys.Comment: Accepted for publication in EP
Groundnut in Southern Africa -Its Status and Research Requirements
The region covered by the Southern African Development Coordination
Conference (SADCC) member countries, Angola, Botswana,
Lesotho, Malawi, Mozambique, Swaziland, Tanzania, Zambia and
Zimbabwe, is very large and diverse. It lies between the
Atlantic (1IOE) and Indian Oceans (410E) and stretches from
near the equator to about 30··S, and has total area of 4.9
million km2• In elevation, it ranges from sea level to
mountains of over 3,500 metres with the major part of the
region being on a plateau with an elevation of between 900
and 3,000 meters. Although 95%............
Groundnut - a global perspective: proceedings of an international workshop, 25-29 Nov 1991, ICRISAT Center. India
This workshop brought together scientists working on all different aspects of groundnut research from all parts of the globe.
Major papers are presented on: production and trade; regional reviews: donor reports: and special topics including information
transfer, processing and products, integrated pest management. genetic resources - including wild species. biotechnology. and
crop modeling. Nearly 100 poster abstracts are included. These cover general topics; genetic resources: biotechnology:
breeding: crop physiology and nutrition: diseases and insect pests: intercropping and weed management: and processing and
products. The proceedings provide a comprehensive record of progress made in groundnut research and production technology
in the 1980s. The workshop recommendations, originating from disciplinary group discussions. outline the future research
requirements of the crop

New groundnut variety brings hope to poor farmers in India
A new variety of groundnut (ICGV 91114 or ‘Anantha Jyoti’) has
generated hope among poor, rain-dependent groundnut
farmers in the district of Anantapur in Andhra Pradesh. Among
its many benefits, it produces higher yields of fodder and
tolerates droughts. The variety was introduced by the
International Crops Research Institute for the Semi-Arid Tropics
(ICRISAT) through the ‘farmer participatory on-farm varietal
selection approach’. IFAD supported ICRISAT through a US $1.3
million grant entitled Programme for Farmer-Participatory

Groundnut and Other Legumes for Crop Diversification in the Central Asia and Caucasus Region
The central asia and caucasus (cac) region consists of the five republics
of kazakhstan, kyrgyzstan, tajikistan turkmenistan, and uzbekistan in central
Asia and the three republics of armenia, azerbaijan, and georgia in the caucasus. The
Landscape of the region is a mixture of mountain, desert and steppe, and the soils are

Designing farmer-participatory varietal selection in legumes
Farmer-partiCipatory approach in agricultural research and development is gaining increas'ing
popularity among researchers, policy makers and develqpment investors. Besides complementing
on-station research, it provides an alternate channel to researchers to allow them to reach
farmers qUickly with greater acceptance of technological innovations among the farming
communities. The farmer-participatory approach ensures that technological innovations are
compatible with local agroecological conditions and socio-economic and cultural profiles of the
farmers. -Researchers, need to follow c
Groundnut research at ICRISAT and its relevance to Asia
Groundnut is currently sown to 21. 7 million ha in more than 100 countries with a
total production of 28.5 million tons (FAO 1994). The world groundnut production
has bee!). increasing in recent years; the increase in production being largely confined
to Asia. An increase in both productivity and area under the crop have contributed to
the increased groundnut production in Asia. In 1994, the groundnut productivity in
Asia increased by 29.98%, area under the crop by 24.40%, and production by 61.30%
over the 1979/81 p,eriod. remains lower than south America (1.83 t ha-1) and north and central America (2.63 t
ha-1). Currently, Asia produces 71.6% of the world groundnut production in 63.3% of
the area. The leading groundnut producing countries in Asia are China, India, Indonesia,
Myanmar, Vietnam, and Thailand......
