Subsistence agriculture in Central and Eastern Europe; how to break the vicious circle?: studies on the agricultural and food sector in Central and Eastern Europe
(2004)Subsistence agriculture is probably the least understood and the most neglected type of agriculture. In a globalised, market-driven world, it remains at the same time a myth and a marginal phenomenon.

Institutions and Technologies for Subsistence Agriculture: How to Increase Commercialization; Zvi Lerman. Policy Options to Overcome Subsistence Agriculture in the CEECs; ... -
Farmer seed systems for pigeonpea in coastal Andhra Pradesh
(2004)Seed is one of the main inputs in all cropping systems. Farmers take utmost care in seed selection as poor quality seed material can result in poor harvests and even crop loss. Seed systems can be classified as farmer and formal seed systems. In the target areas in north coastal Andhra Pradesh, pigeonpea is grown as a subsistence crop and farmer seed systems predominate. Both farmer and formal seed systems operate in the Telangana region where crops are grown with a market orientation. The farmers ... -
Relief seed assistance in Zimbabwe
(2004)Zimbabwe has been a recipient of food or seed aid since the 1990/91 drought, considered one of the worst in 100 years. At present, as in the past, interventions aimed at agricultural rehabilitation and recovery have focused on direct seed distribution ("seeds and tools"). While these interventions are being modified to better address the needs of farmers recovering from disaster, they are still based upon the premise that the emergency has resulted in a loss of seed and other assets, and there is ... -
The ability to fix N is not the only key to delivery of the benefits of BNF to farmers: experience of IITA in the savannas of Africa
(2004)The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological benefit was unequivocal, with more than 100 kg ha' of N2 fixed and consistently positive effects on crop yields. But adoption by farmers has been too low to bring the benefit of BNF to farm households. Based ... -
Relief seed assistance in Ethiopia
(2004)For more than 30 years, the international community has been assisting Ethiopia in recovering from recurring disasters. A continual need for emergency agricultural assistance as a response to droughts, conflict snd famine has led many to question the effectiveness and sustainability of the current interventions and to search for alternative approaches. This paper discribes the approaches used for agricultural recovery in Ethopia, including problem diagnosis, design and implementation of interventions ... -
Vertical rootpulling resistance in maize is related to nitrogen uptake and yield
(2004)Poor soil fertility and recurrent drought are major constriants to maize production in the West Africa savanna. The development of maize cultivars with superior rooting system to absorb nitrogen and water efficiently from the soil is desirable. However, direct measurement of root characteristics for rapid selection of maize lines having tolerance to the two stresses is difficult. Vertical root-pulling strenght, which has been shown to relate well to the rooting charactristics of the maize plant ... -
