ABSTRACT: An eight weeks feeding trail was conducted to evaluate the performance of growing rabbits fed graded levels of Zizipus mauritiana leaf meal in a diets. Dietary treatment were designated A,B, C and D which were made up to 100% concentrate, 15%, 30% and 45% Ziziphus mauritiana leaf meal inclusion levels respectively, twenty cross bred growing rabbits of both sexes averaged 72.8g, balanced for weight and were used in a completely randomized experimental design. They were tattooed and randomly allocated to four dietary treatments replicated with seven rabbits. The rabbits were allowed one week pre-conditioning (adaptation) period during which the animals were collected for feed intake, weight gain, and feed conversion efficiency was calculated. There were significant (p<0.05) differences in all the parameters considered. Diet D had the highest significant (p<0.05) effect in terms of weight gain with......

ABSTRACT:The aim of this study was the identification of acidification risk areas and hotspots, and gaining insight in the acidification process, its causes and consequences.
Soil acidification, an important type of land degradation in Rwanda, and more specifically in the central plateau, is challenging the sustainable use of cropping systems.
The soil profile database has proved to be a useful tool to this study because indicators of both soil acidity and risk for acidification were contained. All these indicators allowed us to assess the relationship between acidity parameters and other soil/landscape parameters. We checked the correlations between acidity parameters themselves and they were found strong (r>0.8) to moderate strong (0.6<r<0.8) except for exchangeable acidity.....

Key words: Topsoil pH, clay and organic matter content, acidification, pH buffer capacity

ABSTRACT: To avoid low fertilization, over fertilization or wastage and determine the optimum level of complete and essential fertilizer needed for better production of Senna obtusifolia crop, the application of levels of NPK 15:15:15 fertilizer on the shoot growth and yield of Senna obtusifolia was investigated. The trial was conducted at training and research farm of Department of Agricultural Education, Federal College of Education (Technical) Bichi in 2019 and 2020 raining seasons. The objectives were to investigate nursery seed sowing, shoot growth and yield of transplanted Senna obtusifolia seedlings in response to different levels (0g/plant, 4g/plant, 8g/plant and 12g/plant or 0kg/ha, 320kg/ha, 640kg/ha and 960kg/ha respectively) of NPK (15:15:15) fertilizer. The trial was randomized complete block design, with four treatments and three replications to give total of twelve trial plots including.....

ABSTRACT: The study was conducted in four major Binatil-3 growing areas of Bangladesh, namely Magura, Kushtia, Jhenaidah, Madaripur and Faridpur district. The average costs of Binatil-3 cultivation were Tk. 48604.49 and Tk. 33218.48 per hectare on full cost and cash cost basis, respectively. The highest production cost was for human labour (42.62%), followed by fertilizer use (16.03%), power tiller (11.65%), and irrigation (10.11%). The average net return per hectare was Tk. 23232.57. The net return was highest in Kushtia (Tk. 33149.58 ha-1) followed by Magura (Tk. 25318.01 ha-1), Jhenaidah (Tk. 23824.76 ha-1), Faridpur (Tk. 19362.44 ha-1) and Madaripur (Tk. 14511.05 ha-1), respectively. The average Benefit cost ratio was estimated at 1.48 and 2.16 on full cost and cash cost basis implying that the Binatil-3 cultivation at farm level was highly profitable. The highest BCR was found in Kushtia.....
