tillage system on yield of maize in the farming system of eastern Zambia. There is need, therefore, to come up with a practice that is both economical and practical under resource poor farmers’ depleted soils where such fallows have a potential. Improved fallows of Sesbania have also been known. Eastern Zambia lies between latitude 10 to 15 S and longitude 30 to 33 E. It borders Malawi to the east and Mozambique to the south. Eastern Zambia covers an area of 70, km2—about 9% of Zambia’s total territory. There are 3 distinct seasons: the warm wet season or agricultural.
farmer-to-farmer contact with early adopters of improved fallows in eastern Zambia. In November of , 18 farmers from Kasungu crossed the border into eastern Zambia, where farmers are at an advanced stage in the testing of improved fallows, and were given hands-on training on the planting and management of improved fallows of sesbania. ICRAF's trials on improved fallows have produced impressive yield responses from maize in Eastern Zambia [Kwesiga et al., ; Kwesiga et al., ]. Similarities in the environment suggest their potential in Malawi’s mid altitude plains Although improved fallows might be.
Comm., March ). Ajayi estimates adoption of improved fallows in eastern Zambia at percent and that of biomass transfer at percent (Ajayi, Pers. Comm., March ). Studies by Phiri et al. () and Keil et al. () found an association between wealth and the planting of improved fallows. In addition the synthesis by Ajayi et al. in Zambia where yields and profits were found to increase substantially from improved fallows, compared to the low-input farmer practice. 1 Screening trials resulted in the selection of new species that in most cases were shrubs and had a shorter life cycle than Sesbania sesban.

Sesbania sesban improved fallows in eastern Zambia: Their inception, development and farmer enthusiasm. The main problems include insects (Mesoplatys beetles on Sesbania, termites), grazing by livestock (pigeon pea), the additional labour required for establishing a fallow (especially Sesbania) and the long period required before benefits accrue.
An estimated 20 farmers have planted improved fallows. Sesbania [Sesbania sesban (L.) Merr.] fallows are being promoted as a means for replenishing soil fertility in N-depleted soils of small-scale, resource-poor farmers in southern Africa.
Knowledge of soil water distribution in the soil profile and water balance under proposed systems is important for knowing the long-term implications of the systems at plot, field and watershed.
Assessing the adoption potential of improved fallows in Eastern Zambia. Declining soil fertility is a key problem faced by farmers in eastern Zambia.
This chapter assesses farmers' experiences of testing improved tree fallows in participatory on-farm trials to increase soil fertility. Deep-rooted improved fallow species (e.g.
Sesbania sesban) may be able to reach underground water and so can be planted part or half way through the wet season (relay planted), and continue to grow through the dry season, improving the soil when there is insufficient water for crops or other fallows to be grown (about 9 months).
Chipata district is situated in Zambia’s Eastern Province, close to the Malawian border. that over over farmers in the four countries have planted improved fallows of Sesbania and Tephrosia.

In coppiced improved fallows, trees were established from bare-rooted seedlings at 1 m × 1 m spacing in plots measuring 10 m × 10 m (Barrios et al., ).In the case of non-coppiced fallows, Sesbania fallows were established using bare-rooted seedlings, while Tephrosia and Cajanus were direct seeded (Sileshi and Mafongoya, ).Once established.

Discussion Paper International Policy Research Institute, Washington, DC. Lal, R. In Eastern Zambia ICRAF researchers and their counterparts in the national agricultural system have developed a promising agroforestry alternative to traditional fallows.
It involves planting Sesbania sesban as 2 to 3 year improved tree fallows in N-depleted fields. Thereafter, the trees are clearfelled and all the twigs and leaf litter.

productivity following Sesbania sesban and Cajanus cajan improved fallow system were measured on a Typic kandiustalf in eastern Zambia. The treatments used in the study were two-year planted improved fallows of Sesbania sesban (L.).
Surveys were conducted between October and June in order to identify the predators of M. ochroptera in sesbania fallows in eastern Zambia. The Heteroptera Afrius yolofa (Guérin.

Roots of trees (Sesbania sesban) and crops (Zea mays) were quantified during two tree/crop cycles in a sequential tree — crop system at Chipata, Eastern Zambia. The experiment included one- and two-year fallows as well as fertilized and unfertilized controls.
The roots of S. sesban represent a standing biomass in the soil of 3 Mg hat-1 in the top m after two years, with. The steady decline in maize production in Eastern Zambia, partly due to removal of fertilizer subsidies, necessitated ICRAF to develop improved fallows of leguminous trees such as Sesbania sesban, Tephrosia vogelii, Cajanus cajan and Gliricidia sepium that fix nitrogen within two to three years.
This case study summarizes the development of improved tree fallows by researchers and farmers in eastern Zambia to help solve the problem of poor soil fertility.
Many farmers are finding that by using improved fallows, they can substitute relatively small amounts of land and labor for cash, which they would need to buy mineral fertilizer. Assessing the adoption potential of improved fallows in eastern Zambia. Back. Year.
