“…The threshold value of exchangeable K in the soil below which maize responses to applied K may be expected in the humid tropics have been put at 0-16 m-equiv/lOOg of soil (Agboola& Corey, 1976). Based on this premise, all the soils could be said to have fairly high K contents, this probably explains the low response to K, but the small increase in yield recorded with K application confirms the findings of Kayode & Agboola (1983) who noted that omitting N, P or K depresses maize yields in the humid tropics. Although the Mokwa soil was developed from sedimentary parent materials with low K reserves and had been cropped for over 10 years, maize response to K was expected, but because of the lower rainfall intensity in this zone, K leaching was minimal.…”

“…Potassium plays an important role in food crop production in the tropics. Its effect on the yield of many tropical crops has been documented by many workers (Agboola, 1972;Amon & Adetunji, 1973;Koli, 1973;Obigbesan, Agboola & Fayemi, 1978;Kayode & Agboola, 1983;Kayode, 1985b). Many attempts have been made to characterize the macronutrient content of leaves aa influenced by K and their relationship to yield.…”

SUMMARYA study designed to investigate the effect of K nutrition on the yield, components of yield and on macro- and micronutrient concentration of maize showed no significant effect of K on yield in forest alfisols derived from basement complex rocks and in savannah alfisols derived from sandstones in the tropics. Potassium addition significantly decreased lodging, but had little influence on cob length, ear weight, shelling percentage or moisture content.Ear-leaf N and K were significantly increased, while Ca and Mg were decreased by K application. All the micronutrient concentrations (Zn, Fe, Mn, Cu) were significantly increased by K application in the forest and savannah zones. Yield was positively correlated with ear-leaf N on both soils.

“…In line with the findings of this study, Mbah et al (2010) and Nweke and Nsoanya (2013b) reported significant increase in available P and plant nutrients in soils amended with wood ash and organic wastes respectively relative to control plots. Kayode and Agboola (1983) attributed the increased CEC in wood ash amended soil to increased cations Ca, K and Na as was observed in the present study. In support of the findings of this study, previous study like Ayeni et al (2008), Adele et al (2010), Nweke and Nsoanya (2013b) and Nweke et al (2014) had shown that organic wastes increased soil OM, N, pH, P, CEC, exchangeable base and reduced soil exchangeable acidity (EA).…”

Wood charcoals were mainly used for smoking of fish, meat and frying of corns and many times dump off as wastes in southeast, Nigeria. Their nutrient recycles and release when used as soil amendment has not been considered and evaluated by farmers in the southeast, Nigeria. This study was therefore carried out to assess the efficiency of wood charcoal technology in improving soil productivity. Influence of wood charcoal from Chlorophera excelsa on soil properties and yield components of maize were evaluated. Four different rates of wood charcoal (6, 4, 2 and 0 tha -1 that received no treatment application) were used. The treatments were laid out in randomised complete block design (RCBD) and treatment means were compared using least significant difference (LSD). The findings from the study showed non-significant (P<0.05) differences in most of the growth and yield components of maize tested. Significant differences were recorded in all the soil properties assessed ) plots was 28.5%. The data generated from both growth and yield component and soil properties showed that the values of parameters tested increased as the rate of wood charcoal applied increased, though this was not consistent in the growth and yield parameters and few cases in soil parameters. In comparison of the four different rates of the wood charcoal applied, 4 tha -1 rate seems to be an ideal than the other rates as it performed competitively better and were able to liberate plant nutrients more than the other rates of wood charcoal though these liberated nutrients were not reflected in most of the growth parameters assessed.

“…The need for Cu was established in a glasshouse study by Kayode & Agboola (1983) in Western Nigeria, but no fertilizer recommendations include Cu. The probability of S deficiency is higher in the savannah zone than the rainforest zone because of frequent bush burning in the savannah zone.…”

SUMMARYField studies were conducted in order to determine the components of yield and response of maizeto soil applied copper and sulphur in the rainforest-savannah transition zone and Guinea savannah zone of Nigeria. Five CuO treatments, 0, 1, 3, 6 and 9 kg/ha, were applied to maize in 1988–90, and grain yield was consistently and significantly increased by the 1 kg/ha CuO treatment. Five S treatments, 0, 10, 20, 40 and 80 kg/ha, were applied to maize in 1989–90, and all treatments increased grain yield significantly in 1989, but only the 10 kg/ha S treatment increased grain yield significantly in 1990. Higher amounts of applied S increased leaf S significantly in the Guinea savannah zone.
