Integrated Fruit Trees-Cereals- Vegetables Systems

Fruit and vegetables can add value to irrigated agriculture production systems resulting in intensification of irrigated agricultureFruit and vegetables can add value to irrigated agriculture production systems resulting in intensification of irrigated agriculture Intercropping is a common practice in agriculture systems of the developing worldIntercropping is a common practice in agriculture systems of the developing world Incorporation of fruit trees and vegetables into irrigated mono-culture systems such as rice is an entry point for largescale adoption of the high value cropsIncorporation of fruit trees and vegetables into irrigated mono-culture systems such as rice is an entry point for largescale adoption of the high value crops

This proposal is based on a farmers ’ innovation initiative at the Gaya region of NigerThis proposal is based on a farmers ’ innovation initiative at the Gaya region of Niger A local farm cooperative developed over a period of 20 years an intricate production system based on year round integrated cultivation of trees, rice and vegetablesA local farm cooperative developed over a period of 20 years an intricate production system based on year round integrated cultivation of trees, rice and vegetables Rows of fruit trees mainly citrus and mangoes are planted at wide spacing sometimes on elevated ridgesRows of fruit trees mainly citrus and mangoes are planted at wide spacing sometimes on elevated ridges In the rainy season trees are intercropped with rice. In the dry season rice is replaced by vegetablesIn the rainy season trees are intercropped with rice. In the dry season rice is replaced by vegetables

The principal role of cereals is to suppress soil born diseases and weeds thus allowing production of vegetables such as onions over a long period of timeThe principal role of cereals is to suppress soil born diseases and weeds thus allowing production of vegetables such as onions over a long period of time This system guarantees optimal conditions for fruit trees production since the fruit trees benefit from the ample water and fertilizers given to the vegetables and riceThis system guarantees optimal conditions for fruit trees production since the fruit trees benefit from the ample water and fertilizers given to the vegetables and rice

Each farmer cultivates an area of 2,500m² Preliminary study of the system shows that this system is very profitable

This system can replace low-profit rice monoculture schemes such as the Office du Niger project in Mali (40,000 hectares) or used to intensify small scale irrigationThis system can replace low-profit rice monoculture schemes such as the Office du Niger project in Mali (40,000 hectares) or used to intensify small scale irrigation It can also be used to further intensify current vegetables production systems such as the onion-sorghum system in Niger It can also be used to further intensify current vegetables production systems such as the onion-sorghum system in Niger

Critical Needs for Collaborative Research Critical Needs for Collaborative Research The integrated fruit-cereal-vegetables approach can be applied in all eco-climatic regions of the developing world (tropics, semi arid tropics and dry subtropics). Species and varieties composition as well as system design will vary from region to regionThe integrated fruit-cereal-vegetables approach can be applied in all eco-climatic regions of the developing world (tropics, semi arid tropics and dry subtropics). Species and varieties composition as well as system design will vary from region to region Study and development of the systems requires tight collaboration among institutes engaged in irrigation, vegetables and fruit research, cereal research and economicsStudy and development of the systems requires tight collaboration among institutes engaged in irrigation, vegetables and fruit research, cereal research and economics
