Growth and yield of okra (Abelmoschus esculentus L.) as affected by organic and inorganic fertilizers Aygarko, K. A study on the effect of poultry and cattle manures on the growth and yield of okra (Abelmoschus esculentus L.) was carried out in the transitional zone of Ghana in 2008 and 2009 in a randomized complete block design experiment with three replicates. The treatments were; 350 kg NPK ha-1, 8t Poultry Manure ha-1, 12t Cow dung Manure ha-1, 175 kg NPK + 4t Poultry Manure ha-1, 175 kg NPK + 6t Cow dung Manure ha-1 and No treatment of manure (control). The combined treatments of 175 kg NPK + 4t Poultry Manure ha-1 and 175 kg NPK + 6t Cow dung Manure ha-1 produced higher levels of the growth and yield parameters than the rest of the treatments in both seasons. The 175 kg NPK + 4t Poultry Manure ha-1 recorded the highest figures of the parameters which were not significantly (P=0.05) different from the figures of the 175 kg NPK + 6t Cow dung Manure ha-1 treatment. The combined treatments were found to be economically profitable. The treatment combination of 175 kg NPK + 4t Poultry Manure ha-1 was more superior in the areas assessed.

Views of preventing borassus aethiopum from extinction among four Communities in Ghana Aygarko, K. An investigation into how Borassus aethiopum might be prevented from extinction among farmers was carried out in four communities (Fiaso, Oforikrom, Nyamebekyere and Bayerenkwanta) in the transitional vegetation zone of Ghana, from April 2013 to July 2013. The farmers were randomly selected from the communities. Data were collected from the farmers using questionnaire supplemented with interviews. In addition to the crops grown for food, farmers also obtained food from the wild/non domesticated plants of which Borassus aethiopum was one. Farmers also used Borassus aethiopum, as a timber source, for the production of wine, for roofing and for making fan, as fire wood and as a medicinal plant. No education had been received on the plant or even on any other non domesticated plant. All the farmers agreed that the plant should be preserved, however, only few (Fiaso – 44%; Oforikrom – 48%; Nyamebekyere – 40%; Bayerenkwanta – 20%) had some ideas on how the plant might be preserved. The few farmers considered cultivation (Fiaso – 40%; Oforikrom – 33%; Nyamebekyere – 50%; Bayerenkwanta – 60%) as a means of preventing the extinction of the plant. Other preservation methods were; prevention of bush burning and indiscriminate felling of the tree, and enacting laws on the usage of the plant. It was recommended that all communities with the support of governments should create community forest reserves/parks made up Borassus aethiopum/non domesticated plant food species, and also enact laws to preserve these plants. Keywords: Borassus aethiopum, extinction, preservation

Influence of grasscutter, chickenm manure and NPK fertilizer on the physical properties of a chromic luvisol, growth and yield of carrot (Daucus carota Atakora, K. A field experiment was conducted to evaluate the effect of grasscutter manure (GM), chicken manure (CM), and NPK on soil physical properties, growth and yield of carrot. The treatments were; no fertilizer or manure (control), 300kgNPK/ha (15:15:15), 10tCM/ha, 3 levels of grasscutter manure (10t, 15t and 20t/ha), laid out in a randomized complete block design with 3 replications. Soil bulk density was highest in the control plot while the sole manure treatments had low soil bulk densities, with the 20t/haGM3 having the lowest value. The 20t/haGM3 treatment also recorded the highest values for the gravimetric moisture content and the total soil porosity. Plant height, number of leaves, root length, root diameter and root yield in the amended treatments were better than the control. Values for the growth and yield parameters of the carrot plant from the 20t/haGM3 treatment were in most cases significantly (P=.05) higher than the rest of the treatments, and the 10tGM/ha treatment had better impact on the parameters than the 10tCM/ha treatment. The highest economic benefit was realized for the 20t/haGM3 treatment.

Sweet potato (Ipomoea batatas) yield parameters, soil chemical properties and cost benefit ratios following incorporation of poultry manure and inorganic NPK fertilizers in low nutrient Ghanaian soils Agyarko, K. The impact of sole poultry manure (6t PM ha-1), sole NPK (200kg NPK ha-1) and their combinations (3t PM + 100kg NPK ha-1 and 1.5t PM + 150kg NPK ha-1) on sweet potato yield parameters and soil nutrients was assessed at Adiembra and Fiaso in Ghana between June, 2011 to November, 2011 using RCBD. Nutritional levels of the sweet potato tubers and the amended soils were analysed with standard laboratory procedures. The 3t PM + 100kg NPK ha-1 produced significantly (P=0.05) the highest tuber yield (tonnes ha-1), tuber length and diameter, and also had the highest percentage of marketable tubers. The total percentage soil nitrogen, organic matter, Total Base Saturation (TEB) and Effective Cation Exchange Capacity (ECEC) were significantly (P=0.05) highest in the 6t PM ha-1 treatment. The 6t PM ha-1 treatment had the highest tuber nutrient values for Ca, Mg, P, S and N. The 3t PM + 100kg NPK ha-1 had the highest cost benefit ratios of 1:4.38 and 1:8.15 at Adiembra and Fiaso respectively. The results demonstrated that combined application of PM and NPK increased sweet potato tuber
