The present study was therefore initiated to evaluate inter and intra-row spacing on yield performance, land-use efficiency and competition in bread wheat-sweet lupine additive series intercropping system. Field experiments were conducted for 2 years in Adet and Debre Tabor experimental sites. The treatments consisted of three inter-rows spacing and 3 intra-rows spacing of sweet lupine. Moreover, the sole crop of wheat and lupine were also included as controls. The experiments were laid out in a factorial randomized complete block design with three replications. The results showed that the combination of 20 cm inter-row spacing with 10 cm intra-row spacing of sweet lupine in bread wheat-sweet lupine intercropping system gave the highest total yield of 4.36 t ha-1 and 4.75 t ha-1 at Adet and Debre Tabor respectively; the land equivalent ratio of 1.43 and 1...

The benefits of intercropping are known to be limited by a variety of factors such as companion crop sowing date and variety. The present study was therefore initiated to evaluate the effect of varieties and planting dates of lupines in bread wheat-lupine under an additive design intercropping system in Northwest Ethiopia. Field experiments were conducted for two years in Adet and Debre Tabor experimental sites. The treatments consisted of four planting dates of lupines and two varieties of lupine. Moreover, the sole crop of bread wheat (Triticum aestivume L.), local lupine (Lupinus albus L.) and sweet lupine (Lupinus angustiflolius L.) were also included. The experiments were laid out in factorial randomized complete block design (RCBD) with three replications. The results ...

An experiment was conducted to study the performance of pearl millet under different technologies in 2013 and 2014 main cropping seasons at the main site of the research center, Aybra, with the objective of evaluating and identifying appropriate combinations of technologies that enhance the production of pearl millet in the study area. About fourteen integrated technologies were applied in a randomized complete block design with three replications. The analysis was done by using SAS software version 9.1, and means were separated through the Duncan multiple range test. Results of analysis of variance showed that yield-related traits of pearl millet were significantly influenced by the integration of technologies in the 2013 cropping season. According to the results, the maximum yie...

Three N sources of fertilizers (conventional Urea, Urea super-granule, and slow-release Urea) with six, one, and three application methods and times, respectively were laid out in a randomized complete block design (RCBD) in three replicates. These treatments and design were equally applied for two sets of experiments under both planting methods. Results revealed that soil-plant analysis development (SPAD) value, LAI, and biomass and grain yields of rain-fed lowland rice were highest with Urea supergranule N fertilizer sources followed by slow-release Urea and conventional Urea applications in both planting methods. Average grain yields of 3.7 and 3.8 tons ha−1 of rain-fed lowland rice were recorded with the application of Urea supergranule N source fertilizer under seedling transplanting and drill row seed planting methods, respectively. Hence, using Urea supergranule tablet is recommendable for getting better grain yield of rain-fed lowland rice without yield penalty in both planting methods.

In addition, with 10 river basins, the country has the potential for a further 3.7 million ha of land where irrigated rice can be produced. The possibility of growing rice in rain-fed and irrigated agro-eco-systems of Ethiopia’s lowland and intermediate areas demonstrates the opportunity that rice presents for poverty reduction in these target ecologies.

Though the crop is a recent introduction to the country; its importance is well recognized as the production area coverage of about 10,000 ha in 2006 has increased to over 50,000 ha in 2018 and number of farmers engaged in rice production has also grown year after year. The engagement in the rice production has transformed the living standard of many farmers. The potential rice production area in Ethiopia is estimated to be over 5,590,895 ha. The earlier rice research endeavors in Ethiopia was started in the late 1950’s and early 1960’s, though successful rice production was not started by then. Emphasis on rice research was given in 1985/6 with the establishment of Pawe and Abobo research centers during the then massive resettlement program. Japan Oversea Cooperation Volunteers has supported the Agriculture bureau and the research dealing with rice research in Gambella between 1984 and 1998. In Pawe area, the Italians have done a...
