The mean crop yields range from a low of about 346.33 kg/ha for sorghum to a high of about 5,342.36 kg/ha for cassava as shown in Table 1.
This means that crop yield and nutrients uptake are influenced by rainfall in a moisture stress condition.
For farmers without access to N fertilizer, the low NUE means reduced crop yield leading to poverty and malnutrition.
To say that yields decline in the Sahel does not mean all crop yields in all of the Sahel.
Which is why we are all here: researchers last year confirmed that the simple existence of earthworms in the soil means that crop yields may increase on average by 25% and the weight of all foliage above ground by 23%.
The inefficiency of farms meant low crop yields, high prices, limited choice, and uneven quality.
The aim of this paper was to derive agroclimatic regions of Ireland using hydro-thermal climate (as expressed by climographs using mean monthly rainfall and temperature) in conjunction with a statistical clustering technique (k-means clustering) to relate crop yield, estimated using mathematical simulation models for grass, barley, maize, potato and soybean to hydro-thermal climate data.
On the other hand, with the exception of block W, out of the three crop types, maize, beans and sweet potato, maize would be the only viable crop to be cultivated in the rest of the irrigation blocks, as it would still yield 90% of optimal maize crop yield even with a mean ECe of 5.9 dS/m.
Biochar application to soil is currently being widely posited as a means to improve soil quality and thereby increase crop yield.
The relationships between black cumin seed yield, Nigellone volatile oil content and seasonal mean crop water stress index values were primarily linear.
