Download Corn Crop Production: Growth, Fertilization and Yield by Arn T. Danforth PDF

By Arn T. Danforth

Corn or maize is a crop that originated in Mexico and has unfold around the world as a big nutrients crop. Sustainable construction of a corn box crop as grain corn for feed, nutrition and biofuels, in addition to candy corn for clean marketplace or processing, and as silage for top strength assets, calls for clinical administration of food besides numerous different crop administration practices resembling right plant inhabitants density, well timed seeding and harvesting, soil water, weeds and pests keep watch over. Corn has turn into the key merchandise within the vitamin of many tropical humans, the most grain used for animal feed in temperate areas, in addition to new shares for plenty of different reasons together with lately used as feedstock for biofuels. speedy growth of grain established ethanol creation in North the US, has already prompted problem approximately destiny meals and feed offers. this significant publication gathers the most recent examine from worldwide during this dynamic box.

Subedi and B. L. Ma per plant or per unit area, presumably by increasing the rate of differentiation of spikelets (Pearson and Jacob, 1987). Knowledge of both soil factors and crop N requirement is a prerequisite to the development of management strategies to maximize the yield response to fertiliser N (Muchow, 1998). The critical timing of N requirement is important to know because N amendment decisions can be made so that irreversible yield loss can be avoided. There are, however, inconsistent reports about the critical timing of N requirement and N uptake by a corn plant.

1985) reported that post-anthesis N nutrition affected the composition of the vegetative growth, but had no effect on yields or N accumulation in the grain. Under low N conditions, however, Worku et al. (2007) observed that post flowering N-uptake and utilization contributed to the improved performance in a set of tropical corn varieties whereas N uptake before anthesis was of little relevance. Figure 3. Relationship between nutrient supply, corn yield and nutrient concentrations in earleaf tissue.

D. Subedi and B. L. , 1992). This test helps in N management in the coming season but not for in-season correction for N - deficiency. Wilhelm et al. (2004) observed that NO3concentration of the individual sample varied greatly from <100 to >8000 mg NO3--N kg-1 DM, and increased downwards the stalk from ear level to the aboveground level. Moreover, the range of NO3--N concentration for grain corn will not be applicable for sweet corn or silage corn because these crops are harvested earlier than the grain crop.
