the aim of the present investigation was to study the growth, yield and yield components of maize (zea mays l.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern iran where this particular crop has not yet been studied in detail. a field experiment was performed in the 2004 5 growing season at the experimental farm of the college of agriculture, shir...

Perennial crops have numerous ecological and agronomic advantages over their annual counterparts. We estimate discrete choice models to evaluate farmers' preferences for perennial attributes of pigeon pea intercropped with maize in central and southern Malawi. Pigeon pea is a nitrogen-fixing leguminous crop, which has the potential to ameliorate soil fertility problems related to continuous mai...

in order to study the competition effects of redroot pigweed (amaranthus retroflexus) and millet (panicum miliaceum) on maize performance under different rates of n fertilizer, a field experiment was conducted in 2009 in the research fields of tarbiat modares university in tehran as a randomized complete block design with factorial arrangement of treatments and three replications. accordingly, ...

MAIZE EAR FASCIATION Knowledge of the genes affecting maize ear inflorescence may lead to better grain yield modeling. Maize ear fasciation, defined as abnormal flattened ears with high kernel row number, is a quantitative trait widely present in Portuguese maize landraces. MATERIAL AND METHODS Using a segregating population derived from an ear fasciation contrasting cross (consisting of 149 ...

A field experiment was carried out to investigate the effects of variety and spatial arrangement on pest incidence, damage and subsequent yield of cowpea in a cowpea/maize intercrop. Two varieties of cowpea (Tvu 13076 and Ife brown) and two spatial arrangements (2:3 maize/ cowpea & 1:1maize/ cowpea intercrops) were investigated. There was Lower population density of Maruca vitrata among the 1:1...

The objective of this article is to apply fuzzy set and interpolation techniques for land suitability evaluation for maize in Northern Ghana. Land suitability indices were computed at point observations using the Semantic Import (SI) model, whereas spatial interpolation was carried out by block kriging. Interpolated land suitability shows a high correlation (R2 = 0.87) with observed maize yield...

The yield and characteristics of Alpha-amylase obtained from some sprouting Nigeria cereals (maize, acha, rice and sorghum) were compared using standard procedures. The result indicated maximum α-amylase yield was attained from 72-120 hours of sprouting cereals). Of all the sprouted cereals, acha gave rise to the highest amylase yield (16.6 ± 0.02x10 and the least was exhibited by maize (11.0±0...

Productivity of maize and soil properties change under alley cropping system consisting of four woody species (Gliricidia sepium, Leucaena leucocephala, Cajanus cajan and Senna siamea) at different nitrogen levels (0, 25, 50, 75 and 100% of recommended rate) were studied in the floodplain ecosystem of Bangladesh. Comparative growth performance of four woody species after pruning showed that L. ...
