No Thumbnail AvailableDocumentParaguay: Financial and Economic Implications of No-tillage and Crop Rotations Compared to Conventional Cropping Systems
Occasional Paper N. 9 - July 1997
1997Also available in:
No results found.The introduction of soybeans to the southern and eastern parts of Paraguay in the early 1970s, followed by wheat in the mid-1970s, using conventional mechanised soil preparation practices with disc ploughs and harrows, initiated a process of widespread soil degradation and erosion. The technique of no-tillage was first used in Paraguay in the late 1970s. Following a slow start, its adoption by Paraguayan farmers gathered momentum increasing from 20,000 ha in 1991/92 to an impressive 250,000 ha i n 1995/96, accounting for about 19% of the land cultivated mechanically. In 1993, the Ministerio de Agricultura y Ganadeira (MAG) and the Deutsche Gesellschaft fur Technische Zusammenarbeit (GTZ) started a project aimed at adapting and further disseminating no-tillage in combination with rotations of both cash and green manure crops in the major grain producing departments of Paraguay. Since very little was known about the economics of these technologies in Paraguay, MAG in association with GTZ, initiated a detailed study which was guided by the FAO Investment Centre. In this paper, the findings of the study are summarised and discussed. -
DocumentPineapple as alternate cropping to control soil erosion in Nepal 2011
Also available in:
No results found.Pineapple cultivation for household consumption is a traditional practice in the hills of Bengri in Nepal. However, the concept of cultivating pineapple in degraded land as a means of erosion control and alternative income source was itself a new practice adopted by local farmers. Cultivation of pineapple is appropriate in sloppy land, prone to erosion and even degraded lands. Before adopting the practice, maize was cultivated for household consumption. However, land management practices such as tillage were not properly adopted for maize cultivation and thus resulted in severe soil erosion. Due to unpredictable rain and longer droughts even during rainy season, maize cultivation is more risky. The objective of pineapple cultivation is to minimize soil erosion and promote the rehabilitation of degraded sloppy lands for additional income through pineapple cultivation. -
Book (stand-alone)International Conference on Domestication and Commercialization of Non-Timber Forest Products in Agroforestry Systems 1996
Also available in:
No results found.The International Conference on Domestication and Commercialization of Non-Timber Forest Products in Agroforestry Systems, hosted by ICRAF, was held in Nairobi, Kenya, from 19 to 23 February 1996. This was the first world-level meeting to be held exclusively to draw attention to issues dealing with domestication and commercialization of non-timber forest products in agroforestry systems.
