Effects of single basal application of coated compound fertilizer on yield and nitrogen use efficiency in double-cropped rice

Abstract

Fertilizer plays an important role in increasing rice yield. More than half of all fertilizer applied to the field is not taken up, resulting in environmental damage and substantial economic losses. To address these concerns, a low-cost, coated compound fertilizer named “Xiang Nong Da” (XND), requiring only a single basal application, was studied. A two-year field experiment was conducted to test the effects of XND application on rice yield and nitrogen fertilizer use efficiency. An ordinary uncoated compound fertilizer (UNCF), with 20% more nutrients and split application was selected as the control. The yield of XND-treated rice was only 3.1% lower than that of the control, an insignificant difference. There were no significant differences between N use efficiency indices of the two fertilizer treatments except for N partial factor productivity (PFP N). PFP N of XND treatment was 19.7%–23.2% higher than the control, a significant difference. This result indicates that a 20% decrease in N application rate is possible with XND without yield reduction and with savings in both labor and time.

Life Hack for Plant Science: How To Make Leaves Flat to Measure Leaf Area

Simple answers to really difficult practical questions in agriculture and ecology. Surely, with Petiole :).

If you have ever tried to measure leaf area of wheat, soybean or pear, share your experience with us! We suggest you can tell how “easy” it was to make the surface of leaves flat and not curvy. Considering our hands-on experience, it is almost impossible particularly in wheat and rice, on the early stage of vegetation!

There are many life hacks on how to glue these leaves or stick them. However, after such manipulations, these leaves are not acceptable for any other further measurements or research.

Hence, we found an elegant solution to this problem. It is applicable for almost any type of leaves (cereals, fruit or vegetables). It makes their surface completely flat and ready-to-measure. Do you want to try it :)?
