Research on the effect of split nitrogen application on wheat grain yield and quality under conservation agriculture. The study was conducted during the 2016-2017 and 2017-2018 fall-winter cycles in the Bajío region of Guanajuato. The effects of study locations, wheat varieties, nitrogen fractionation, and their interactions were evaluated.
This database contains data on grain, biomass, protein, and calorie yields from on-station trials in Zimbabwe, conducted at the Domboshava Training Centre (DTC) (17.62°S, 31.17°E) and the University of Zimbabwe farm (UZ) (17.73°S, 31.020°E), characterized by different soil types. The trials tested maize monocropping, maize-legume rotations, and intercropping with various layouts (traditional intercropping and double-row strip cropping), with and without fertilizer application. Two contrasting legumes, cowpea and pigeon pea, were included in the cropping systems. The experiment was established during the 2019/2020 growing season, but data were collected from the 2020/21 to 2022/23 seasons to allow the rotations to develop. It was carried out under Conservation Agriculture and rainfed conditions. The dataset is divided into three parts: 1) Field measurement, including treatments, grain yields, and crop biomass; 2) Calculations at the cropping system level (total biomass, calories, and proteins); 3) Processed data used to evaluate the stability of each cropping system, as shown in a radar plot presented in the related paper.
This database contains grain, biomasss and nutritional yield data from on-farm trials in Kasungu, Mchinji, and Lilongwe districts of central Malawi, conducted over three cropping seasons (2014–15 to 2016-17). The trials tested sustainable and resilient cropping systems, including Conservation Agriculture (CA) with minimum tillage, glyphosate herbicide, and maize-legume rotations, compared to conventional ridge-and-furrow sole maize (True farmer practice). The experiments were conducted on 24 farms, with each farm serving as one replicate. Data collected included grain yield, biomass, protein, and energy yields, providing insights into system performance and sustainability.
