ข้าวโพดจะให้ผลผลิตสูงเมื่อได้รับธาต

Corn yield will be high when it receives adequate and balanced trace elements by yongyuth and faculty (2551) describe the main nutrient requirements for growth and yield of corn. Nitrogen (N) play an important role in the growth of corn, since the first stage until the creation of the seed. Corn requires nitrogen distance is the length of time that corn flowering male and female flowers are in the age range of 18-30 days and 39-65 days after planting with corn nitrogen uptake by up to 7 kg/Rai and 50 respectively, so. If during the life of such growth. Soil nitrogen content is not sufficient to affect the growth and yield of maize (Department of agriculture, 2548)

Corn yield is higher when given adequate and balanced elements. By Yongyutt et al (2551) described the need macronutrients on the growth and yield of corn on the nitrogen (N) plays an important role in the early growth of corn to create seeds. In the Corn Nitrogen is the most preferred maize flowering period male and female flowers. In the age of 18-30 days and 39-65 days after planting. Corn Nitrogen Uptake of up to seven and 50 kg / ha, respectively, if during the period of such growth. The amount of nitrogen in the soil is not enough. Will affect growth. And yield of corn (Department of Agriculture, 2548).
