“…Application of fungicide decreased defoliation and improved seed yields as much as 49% under onfarm conditions, when averaged across all locations over two years. This yield response is similar to that obtained from previous on-station studies in Ghana (Naab et al, 2005) and other parts of Africa (Kanniyan and Haciwa, 1990;Subrahmanyam et al, 1997;Waliyar et al, 2000).…”

“…Fungicide use is not a common practice in developing countries of this region partly because of lack of resources and lack of awareness of the extent of economic and yield benefits from application of fungicide. Applications of fungicides have shown yield improvement in Ghana (Naab et al, 2005). Studies under on-farm conditions are limited in Ghana or other parts of West Africa.…”

Peanut (Arachis hypogaea L.) is an important component of cropping systems in West Africa. Identifying production constraints in farmers' fields and evaluating possible management strategies are of prime importance to improve peanut productivity and adoption of new technologies. The objective of our research was to study the influence of fungicides and phosphorus application on severity of leaf spot, dry matter production and pod yield of peanut crops grown in onstation and farmer participatory tests (on-farm conditions) in Northern Ghana. On-station tests to evaluate yield benefits of fungicide sprays and applications of phosphorus were conducted at Wa. On-station tests included two fungicide treatments (no-spray versus fungicide spray) at four P fertilizer levels (0, 30, 60 and 90 kg P ha 21 ). On-farm tests were conducted in three villages Nakor, Piisi and Janguasi with participation of 6-11 farmers per village. On-farm tests included three treatments: (i) farmers' practice of nofungicide and no-fertilizer (control), (ii) only fungicide, and (iii) combination of fungicide and phosphorus. The commonly grown Spanish type cultivar Chinese (90-d duration) was selected. Both leaf spot and lack of phosphorus nutrition were yield-limiting factors in on-farm tests. Applications of fungicide were effective in controlling leaf spot and improved peanut pod yield on average by 49% in the three tested field sites in on-farm tests and by 40% in on-station tests. Application of phosphorus to fungicide-treated plots further increased pod yield by 32% when compared to fungicide alone in on-farm tests. Combination of both fungicide and P fertilizer improved peanut pod yield by 95% (ranged from 75 to 120%), when compared to farmers' practice of no-fungicide and no-fertilizer.

“…Seed yields ha -1 obtained in experiments 1 and 2 are similar to those reported by Méndez-Natera (1995) who in a trial with 11 groundnut varieties in the savanna of Jusepín, Venezuela found that yields ranged between 485.3 and 1838.2 kg of seeds ha -1 , while Méndez-Natera et al (2003) in the savanna of Jusepín, Venezuela with 24 of the 25 varieties of groundnut of experiment 3, found that seed productions ranged from 194.6 to 926.6 kg ha -1 . Also, Naab et al (2005) studied the effects of sowing date, variety cycle, and fungicide applications on disease severity, biomass and pod production of groundnut cultivated under dryland conditions in Ghana and found that early sowings after onset of rains produced more biomass and pod yields in comparison to late sowings for cvs. Chinese and F-mix.…”

“…Most of the late leaf spot spores are formed on the lower surface giving it a rough and tufted appearance, where as upper leaf surface is generally smooth. Late leaf spot caused by P. personata is one of the most important and destructive diseases causing accountable qualitative and quantitative losses (Naab et al, 2005). The causal organism is air borne and soil inhabiting and responsible for late leaf spot disease of groundnut, thereby incurring yield losses to the tune of 50-80 per cent (Hegde et al 1995;Grichar et al, 1998;Nutsugah et al, 2007).…”

Experiments were conducted to investigate the effect of date of sowing on groundnut cultivars against late leaf spot disease severity, defoliation, frequency and size of the leaf spot which revealed that all these aspects were significantly influenced by the date of sowing and crop varieties which directly affect the pod yield and test weight. The crop sown early on 25 th June exhibited maximum mean late leaf spot disease severity (range 43.63 to 54.05%), defoliation (range, 17.22 to 22.30%), frequency (range, 1.32 to 1.78 / mm 2 ) and size (range, 1.49 to 1.56 / mm 2 ) and thereby gave reduced pod yield (range, 1225 to 1720 kg/ha) and test weight (28.66 to 32.97 g) followed by 10 th July and 25 th July. Among the groundnut cultivars, susceptible cv. JL 24 exhibited maximum mean disease severity (range, 35.94 to 54.05 %), defoliation (range, 11.61 to 22.30 %), frequency (range, 1.23 to 1.78 / mm 2 ) and size (range, 1.26 to 1.56 / mm 2 ), followed by TAG 24 and TG 26. However, LGN 1 exhibited least mean disease severity, defoliation, frequency and size with the highest pod yield (ranges, 1720 to 2332 kg/ha) and test weight (ranges, 32.97 to 38.59 g).
