Research and Application of Precision Fertilization on Maize
نویسندگان
چکیده
The current precision fertilization technology of maize is still incomplete and unsystematic. In the paper, according to the fact of maize production of black soil zone in Jilin province, spatial variability of soil nutrient is studied, precision fertilization model of maize is introduced, a web-based expert system for maize precision fertilization is developed. Finally, the precision fertilization is implemented by the variable rate fertilizer. The practice shows that, by the program proposed in this paper, the maize yield was increased by nearly 10%,and the fertilizer was saved about 10.5%.Furthermore ,the profit and maize quality was increased and the environmental pollution and input cost was decreased.

Effects of organic and inorganic amendments on weed management in sweet maize
Field experiments were conducted to determine the effects of organic andinorganic amendments on weed suppression in sweet maize cultivation (Zea maysL.). A randomized complete block design was employed with four replicates pertreatment with each organic amendment used at half (x/2), single (x=10 t ha-1) anddouble (2x) rates (organic fertilization: cow manure, poultry manure and barleymulch; syn...
متن کاملEffect of fertilizer management and the application of zeolite on agronomic traits and grain yield of maize (Zea mays L.) hybrids under deficit irrigation conditions
Drought stress is considered as the most important limiting factor for growing of crops such as maize. Under low irrigation conditions, proper nutrition of plants can improve the effects of drought stress. This experiment was carried out in order to investigate the effect of nutrition management along with application of zeolite on agronomic traits of two hybrids of maize under deficit irrigati...

In this study, nitrogen fertilizer was applied to corn (Zea mays L.) at conventional (excessive) and recommended levels, and the growth response was assessed by measuring plant height and stem perimeter. Corn plant maximum height was observed in recommended rates of N fertilizer treatment, and the height without N fertilizer was the same as that receiving excess N fertilizer. Stem perimeter was...
