Climate variability and difficult economic conditions are pressuring farmers to produce higher (maize) yields with fewer inputs, per hectare. The remote sensing of crop specific structural parameters are essential in identifying the particular growth stages of the maize crop which require specific tasks...
AMMI analysis of grain yield for drought-resilient maize hybrid selection The average grain yield differences of the experimental hybrids varied widely, ranging from 8.46 to 15.94 ton per hectare. Table 3 displays the two-year grain yield of the 20 maize hybrids across three environments in Inner...
Permanent Secretary in the Ministry of Lands, Agriculture, Fisheries, Water and Rural Development, Dr John Bhasera, said smallholder farmers using the farming technique achieved an average yield of 5,3 tonnes per hectare in 2020-2021 season against the average small-scale farmer yield of 1,16...
Maize is the most important cereal cultivated in Ethiopia as it ranks second after teff in area coverage, first in total national production and yield per hectare (CSA 2015). The national maize yield average is of 2.95 t/ha (CSA 2012). This is far below the world’s average which is ab...
As a result the yield was only 0.76 tonnes per hectare (t/ha), 40% below the long term average27. This equated to 57% of the national food requirement and left 5 million people requiring food aid27. To mitigate these impacts, in the mid-2000s, the Government of Malawi (GoM) ...
and Zimbabwe between 2016 and 2019. The results demonstrate that FNP hybrids deliver an average yield increase of 200 kg per hectare, representing a 10-20% increase at current sub-Saharan Africa yield levels where farmers face frequent drought and sub-optimal soil fertility. The FNP yield advanta...
Thus, the best maize grain yield performances were obtained with treatments T11; T13; T14; T10 and T12 with respective values of 3.08 ± 0.07; 3.07 ± 0.04; 3.05 ± 0.04; 3.04 ± 0.04 and 3.03 ± 0.01 tonne per hectare (t/ha). Classification of Treatments...
It would seem, therefore, that yield gains of U.S. maize since the mid-1980s cannot be attributed to application of increasing amounts of nitrogen fertilizer on maize plantings. Plant density—the number of maize plants per hectare—also increased steadily through the years following World War...
Of the three cereals, maize had a yield increase of nearly 2 tons over the 25-year period (up from 3.9 tons/ha, i.e., an increase of 76 kg/ha/yr or a simple average of 2.0% per annum [pa]), compared to increases of 1 ton for rice and wheat (increases of 39 and 40 kg/ha...
Similar to previous studies in Ghana and Africa south of the Sahara, the results show that there is a statistically significant maize yield response (that is, 1 kilogram of nitrogen leads to a yield increase of 22 kilograms per hectare)....
