“…The association of fresh ear weight with percent prolificacy, rows per ear, moisture content and harvest index was also found to be of positive nature but with non-significant magnitude at both the genotypic and phenotypic levels. These results are in close conformity with those of [31], who concluded also the positive and significant association of fresh ear weight with Ear length, shelling percentage, ear diameter and grain yield.…”

Knowledge of correlation between grain yield and its contributing components enhances the effectiveness of breeding programs through the use of appropriate breeding method. Twenty seven maize Genotypes including 20 F1 hybrids, 5 parental inbred lines and two checks were evaluated in a randomized complete block design with three replications under the environmental conditions of Cereal Crops Research Institute (CCRI), Pirsabak -Nowshera, KPK, Pakistan during spring 2011. Correlation among all measured parameters has been calculated. Grain yield revealed negative genotypic and phenotypic correlations with earliness traits i.e. days to 50% tasseling, pollen shedding and silking. Although, genotypic and phenotypic correlations of grain yield were significantly positive with yield contributing traits.

“…It is now found all over the world and its natural habitat is the tropics. In Nigeria, Maize is one of the major staple foods, fodder and industrial crop for commercial and subsistence level where it is grown in all agro ecological zones [4,5]. Maize is predominantly the cereal crop of Southern Nigeria, just as sorghum and millet are in the Northern Nigeria [4].…”

The research was carried out in the month of April, 2018 to determine the effect of solid (granular) and liquid (foliar) fertilizers application on the growth and yield of maize in soils of Obubra. Five (5) composite soil samples were collected at the depth of 0-20 cm for the analysis of physical and chemical properties before application of the fertilizers. The experimental layout was randomized Complete Block Design (RCBD) with three treatments and five replications in a plot area of 25 m x 20 m (500 m2) which corresponds to 0.05 ha-1. The plot was designed and blocked into subplots, each measuring 6 m x 4 m (24 m2). Each block was separated from the other with a distance of one meter (1 m) apart and between subplots 0.5 m apart. Three treatments made up of treatment one (T1) zero application at 0 kg ha-1, treatment two (T2) liquid (foliar) N.P.K 20:20:20 at the rate of 100 mil of N, 50 mil of P2O5, 33.3 mil of Mp ha-1 and treatment three (T3) solid (granular) N.P.K 20:20:20 at the rate of 44.4 kg of N, 40 kg of P2O5 and 33.3 kg of Mp ha-1 were replicated five times making a total of fifteen (15) subplots. Parameters of plant heights and number of leaves were observed at 6 and 8 weeks after planting. Plant heights, number of leaves, number of cobs, weight of 1000 seeds in each subplot and weight of grain after shelling were analyzed respectively. Results on soil analyses showed that the soil texture was sandy loam with deficiencies in primary nutrients and other nutrients. On the plant heights, the result was significant (P≤0.05) and on the number of leaves, the result for 6 weeks was not significant (P≥0.05) while that of 8 weeks was significant (P≤0.05). On the number of cobs, 1000 seeds and weight of grain after shelling were also significant (P≤0.05). The solid (granular) fertilizer showed to be more effective than liquid (foliar) fertilizer and should therefore be recommended for the growth and yield of maize in the area.

“…Demand for maize in developing countries is projected to surpass both wheat and rice by 2020 (Akinbola et al, 2009). If care is not taken, this may not be actualized, and this is because in 2003, the projected output for maize production in Nigeria was 9.88 million metric tonnes, but the actual output realized was 7.02 million metric tonnes (Eleweanya, et al, 2005); a reduction of the expected output by 2.84 million metric tonnes.…”

Field trials and a pot experiment were conducted during the 2005 and 2006 cropping seasons at Michael Okpara University of Agriculture, Umudike, Nigeria, to assess the effect of various agricultural wastes ash on nutrient concentration, growth and yield of maize in a Haplic Acrisol. The treatments comprised palm bunch ash, kitchen residues ash, cocoa pod husk ash, saw dust ash, calcium carbonate, oyster shell ash and a control. Each of the ash was applied at five levels: 0, 2, 4, 6 and 8 tonnes per hectare. They were replicated three times in a split plot completely randomized design for the pot experiment and randomized completely block design for the field trials. The effects of the treatments were measured on nitrogen, phosphorus, potassium, calcium, and manganese and iron concentration in maize crop. Other plant parameters measured were maize height at 8 weeks after planting, stem diameter, stover weight and grain yield weight in the field trails. The results obtained showed that all the agricultural wastes significantly (P < 0.05) increased the concentrations of nitrogen, phosphorus, potassium and calcium. They also significantly (p<0.05) reduced the concentration of iron and manganese in the plant. The wastes applied significantly increased the plant height at 8 WAP, maize stem diameter, stover weight and grain yield. Among the treatments tested, 6t/ha of cocoa pod husk ash significantly (P<0.05) increased nitrogen concentration in the maize from 0.49 in the control to 5.17%. Plant height, stem diameter and stover weight were also increased by the application of 6t/ha of cocoa pod husk ash. While 4t/ha of kitchen residue ash, 4t/ha of oyster shell ash and 4 t/ha of cocoa pod husk ash significantly (P<0.05) increased the concentration of phosphorus from 1.01% to 4.98%, calcium from 0.4% to 6% and potassium from 0.19% to 0.42% respectively. The soil pH correlated negatively with iron and manganese concentration, positively with phosphorus and calcium concentration. These results show that maize can be grown successfully on Haplic Acrisol of the Southeastern Nigeria using waste from agricultural products.
