The open-pollinated corn (Zea mays L.) cult Gaspé Flint and three hybrids, Guelph GX122, Harrow 691, and Pioneer X306, were selected to examine the effects of photoperiod and temperature on the number of days to tassel initiation. The range of maturity of this material varied from extremely early to subtropical. The experiments, conducted in growth cabinets, examined photoperiods of from 10 to 20 h in 21/2-h increments. Constant day–night temperatures examined were 20, 25, and 30 C. Photoperiod and temperature affected number of days to tassel initiation. The response was not consistent for each genotype. As daylength increased from 10 to 20 h all but the earliest genotype, Gaspé Flint, took longer to reach tassel initiation. The latest hybrid, Pioneer X306, was affected relatively more by photoperiod. The delay in tassel initiation with longer photoperiods was apparent at all temperatures; however, the magnitude of the response was less at the high temperature. With longer photoperiods, there was an increase in the amount of vegetative growth and development prior to tassel initiation. This was apparent from the greater number of emerged leaves, the longer stem length, and the greater plant dry weight at tassel initiation.

Different Doses

Sweet corn has a sturdy and strong stem growth and is very suitable for cultivation in tropical climates. Research on the effect of horse manure compost combined with NPK fertilizer on the growth of sweet corn has been done with the aim of obtaining information: (1) the effect of different doses of horse manure compost on the growth of sweet corn, (2) the effect of different doses of NPK fertilizer on the growth of sweet corn, (3) The interaction effect of horse manure compost and NPK fertilizer on sweet corn vegetative growth. The application of NPK fertilizer was carried out with 4 treatment doses while the application of horse manure compost was carried out with 5 treatment doses. In this study, information was obtained (1) the application of NPK fertilizer increased the growth of sweet corn, (2) the application of horse manure compost increased the growth of sweet corn, (3) There was no increase in growth of sweet corn due to the combination treatment of NPK fertilizer and horse manure compost

This study highlights the effect of a biostimulant based on Trichoderma, indigenous antagonistic fungus from the region of Touggourt, on the development of a local variety of corn. This study was conducted at the experimental station of National Institute of Agronomic Research (Sidi Mehdi, Touggourt) as a complete randomaize block designe. The examined agro-morphological parameters showed that the application of this bioproduct stimulates vegetative growth of the plant. Besides, better germination and earliness of seeds. The results showed more interesting values were obtained in the treated plots (height = 135.9 cm, diameter = 28.9 mm, surface of leaves = 318 cm2, Pan = 10.2 panicles/plant) compared to those of the controls (height = 98.6 cm, diameter = 23.7 mm, surface of leaves = 260.4 cm², Pan = 7.4 panicles/plant). Statistical analyzes confirmed the existence of a very highly significant difference between treated and control subjects.

SUMMARYMaize was grown for six years on two soil series in annual rotation with groundnuts, soyabean, lab-lab and sunflowers, and for up to four years after two year crops of pigeonpea. Nitrogen left by the annual legumes was estimated to vary from 0.0 to 52.2 kg ha−1 depending on year, soil and species. Summed over three successive maize crops, nitrogen left by two year crops of pigeonpea varied from 23.5 to 109.6 kg ha−1. Vigorous vegetative growth and low seed yield in the legume were associated with increased residual nitrogen. Groundnuts left more nitrogen on the more fertile soil. High rainfall at the beginning of the maize cropping season was associated on one soil series with the complete disappearance of residual nitrogen from the immediately preceding legume crop.

A field experiment was carried out to evaluate the effect of the application of poultry manure and wood ash on the growth and grain yield of maize (Zea mays L.). The poultry manure was applied two weeks prior to planting to allow for proper decomposition. Wood ash was applied a day before planting. There were three treatments in all including the control and the treatments were arranged in a randomized complete block design (RCBD) with three replicates. Plant height and leaf area were taken at three weeks after planting to nine weeks after planting with an interval of two weeks. The grain yield was taken at eleven weeks after planting and was dried, weighed and recorded. The results showed that poultry manure significantly increased plant height (192.0 cm) and grain yield (4.83 t/ha) but has no significant effect on the number of leaves and leaf area with 12cm and 3403.6cm2 respectively. The values of plant height and leaf area of the control were relatively high compared with other treatments. This can be attributed to the availability of Nitrogen in the soil. The wood ash was found to give the lowest values for nitrogen as well as vegetative growth of maize, this could be attributed to the fact that nitrogen tends to volatilize when in contact with alkaline mediums and consequently affect vegetative growth of maize.
