Gross Primary Production Estimation in Crops Using Solely Remotely Sensed Data

Agronomy Journal, 2019
Gross primary production (GPP) is a measure for crop productivity, indicating yield and expressing C exchange of agro‐ecosystems. A multitude of satellite sensors at varying spatial and spectral resolution brings a possibility to use remotely sensed data for regional and global GPP estimation.

The comparison of nitrogen use and leaching in sole cropped versus intercropped pea and barley

Nutrient Cycling in Agroecosystems, 2003
The effect of sole and intercropping of field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.) and of crop residue management on crop yield, NO3- leaching and N balance in the cropping system was tested in a 2-year lysimeter experiment on a temperate sandy loam soil.

Effects of Delayed Hand Weeding on Sole-crop Cassava in Sierra Leone

Experimental Agriculture, 1978
SUMMARYThe effects of delayed hand weed control at 30-, 45-, 60-, 90-day intervals, and no weeding, on sole-crop cassava, was studied in two experiments on the upland soils of Sierra Leone. Timing and frequency of weeding were important in influencing root number and root yield, and delayed weed control depressed both attributes. The critical period of

The role of intercropping and sole cropping across environments of contrasting level of productivity in Ethiopia

2016
Intercropping is a common practice in traditionally low productivity smallholder farming across Africa. However, as technological improvements and farmers’ investments increase the level of crop productivity, whether intercropping or sole cropping systems remain the best option, is not known.
