ABSTRACT A study was conducted to determine the effects of different growth media and different poly bag sizes on the growth of cocoa seedlings in the nursery. The experimental design was split plot design with three replicates. The treatments were soil (S), carbonated rice husk (CRH), cocoa pod husk (CPH), cocopeat (CP) , sawdust (SD), S+CRH, S+CPH, S+CP, S+SD, CRH+CPH, CRH+CP, CRH+SD, CPH+CP, CPH+SD, CP+SD and the three polytene bag sizes were 12.5 cm x 18.5 cm (small), 10.0 cm x 35.0 cm ...
ABSTRACT In order to determine genetic variability in some accessions of Africa eggplant, open field experiments were conducted in two separate locations, one at University of Ghana farm, Legon and the other at the Forest and Horticultural Crops Research Centre (FOHCREC), OkumaningKade simultaneously. The experimental design used was the Randomized Complete Block Design (RCBD) with three (3) replications. The combined analysis of variance was carried out for the data gathered. The effect of...
Early sprouting of yam tuber is a typical problem during storage resulting into weight losses, deterioration, shrinkage and reduction in quality. This research work therefore carried out investigation on the application of vibration technique for the control of physical properties of yam (Dioscorea spp.) sprouts during storage in FUNAAB, Nigeria environment. The physical properties (length, number and weight of sprout, number of leaves and weight of roots) of the yam sprouts were determi...
ABSTRACT The pathogenicity of fungus, Fusarium oxysporum f. sp. lycopersici and nematode, Meloidogyne incognita on growth, yield and wilt severity was studied on two tomato varieties, Mongal F1 and Petomech in a randomized complete block design, factorial experiment with three replications on the University of Ghana and National service farms from July 2018 to June 2019. Each plot had an area of 10 m2 with 25 plants. Fusarium inoculum of 1.3×106 cells per 5 mL was inoculated on fields natur...
ABSTRACT Amaranth is one of the African indigenous vegetables that is gaining popularity due to its nutritional, medicinal and economic values. Its potential as a source of food security in East Africa and most parts of the world has heightened demands for the once neglected crop. In Kenya and Tanzania, the Lepidopteran defoliators are important pests of the crop which can cause up to 100% yield loss. Little information on the population dynamics of these pests make their management difficul...
ABSTRACT Green (fresh) maize (Zea mays L.) provides food security and income to farmers especially when other crops are still in the field. However, research on green maize variety is scarcely reported in literature or information on suitable genetic material (germplasm) for green maize production. Developing maize for fresh maize production in the southeastern Nigeria was carried out in the Center for Agricultural Research, School of Agriculture and Agricultural Technology, Federal Universi...
ABSTRACT The parasitic weed Striga hermonthica (Del.) Benth. of the Scrophulariaceae family constitutes one of the most economically important biological constraints in maize production in the sub-Saharan regions of Africa. The type of gene action involved in the inheritance of resistance to Striga hermonthica was investigated using the open-pollinated population, TZLComposite-1 Cl in a North Carolina design 1 scheme. Recombination were done among the best families and also the poorest perfo...
Abstract This study was carried out in the laboratory of Entomology, Plant Protection Department , College of Agricultural Studies , Sudan University of Science and Technology (SUST) to evaluate the lethal effect of hexane extracts of the leaves of Rehan (Ocimum basilicum) and Lupine seeds (Lupinus termis) against the 3rd larval instars of spiny bollworm (Earias insulana Boisduval, 1833). Also further experiments were conducted to investigate the efficacy of sesame oil as a synergist. Four co...
Cucumber (Cucumis sativus L.) belongs to the Cucurbitaceae family. It is a major vegetable crop worldwide and develops rapidly, with a shorter time from planting to harvest than most crops. It is a monoecious annual climber or creeper that has been cultivated for over 3,000 years and is still widely cultivated today. The fruit is soft, succulent with high water content, roughly cylindrical and elongated with tapered ends. The plant shades one another, being allowed to creep on the ground ther...
ABSTRACT Three field experiments to investigate the partial nutrient balance (N and K) in cassava/soybean intercrop system were conducted at University of Nigeria, Nsukka in a derived Savannah location of South Eastern Nigeria. Effect of fertilizer rate, residual fertilizer and soybean residue management on growth and yield of soybean and cassava and soil nutrient reserve were studied. Soybean growth and yield were significantly affected by their varieties, fertilizer rate and cropping syste...
ABSTRACT These studies on evaluation of cassava cultivars and intercropping with legumes as an integrated nematode control strategy in cassava production were carried out as 15 greenhouse/microplot and field experiments. Of the 200 cultivars screened for resistance to Meloidogyne spp., only 76 survived and from this lot only 3 lines 77/227, TMS30572 and 73/222, showed any resistance while 7 others namely NR8082, 75.668, 73/238 (Egbenegbe), 73/295, 73/118, 75740(Panya), 82/00661 and 73295B we...
ABSTRACT A diallel set consisting of p 2 combinations (p parents ½ P(p-1) F2 hybrids, and the backcrosses among eight rice breeding lines were grown in replicated trails. The eight rice breeding lines were selected from an initial thirty one rice breeding lines comprising eighteen medium maturing rice lines and thirteen early maturing rice lines on the basis of their maturity (early to medium ), plant height (semi – dwarf to intermediate ), tillerring ability (low to high) and spikelet fe...
ABSTRACT The main Karoo Basin of South Africa contains a relatively continuous sequence of continental deposits that accumulated over a 100 million year period from Permo-Carboniferous (280 Ma) to early Jurassic (180 Ma). In the southwestern region of the basin the Karoo succession is approximately 4 000 m thick, the upper half of which consists of vertebrate fossil-bearing fluvial rocks of the Beaufort Group. This study deals with Lower Beaufort (Adelaide Subgroup) strata belonging to the Te...
EXTENDED ABSTRACT The preliminary experiment was done by using Jaffa orange variety to assess the effects of different concentrations of hexanal, calcium chloride and smoke treatment on physicochemical quality. Jaffa orange fruits were separately (i) dipped in hexanal at 0.01%, 0.02% and 0.04% volume/voume for five minutes (ii) dipped in calcium chloride 1%, 2% and 4% weight/volume for five minutes (iii) fruits were smoked by burning 0.5 kg, 1.0 kg and 1.5 kg of dry banana leaves (iv) Untre...
ABSTRACT Performances of three sorghum (Sorghum bicolor L. Moench) genotypes (Wahi, Hakika and Pato) and inorganic soil amendments were studied under naturally Striga asiatica [L.] Kuntze infestation for one cropping season (2015/16) in two locations, using a split plot design laid out in a randomized complete block design with four replications. A susceptible sorghum (Pato cultivar) was used as a bioassay to evaluate the effectiveness of reduced rates of N under Striga infestation. At Hombo...
