Abstract This paper presents a preliminary study of the Middle Palaeolithic lithic industries recovered at six selected open-air sites in Latium region (central Italy), part regional cultural complex known as “Pontinian”. The pedo-stratigraphic analysis combined with 40Ar/ 39Ar age constraints on permits us to provide for first time geomorphological and chronological (300–40 ka) framework sever...
Nitrogen pedo-transfer functions were developed for different land use types, soil depths and agro-ecologies across eight states in Nigeria. The results showed that total nitrogen had a good relationship with the organic carbon; therefore, based on between carbon as other parameters (pH, particle size distribution) little contribution no significant correlation (p>0.05) nitrogen. Correlation...
The field experiment was carried out at the Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj during Rabi season 2021-22 on Mustard crop. performed in randomized block design with ten treatments three replication. soil experimental plot sandy loam texture, nearly neutral reaction (pH 7.1), low organic carbon (0.36%), availabl...
A crop can be represented as a biotechnical system in which components are either chosen (cultivar, management) or given (soil, climate) and whose combination generates highly variable stress patterns and yield responses. Here, we used modeling and simulation to predict the crop phenotypic plasticity resulting from the interaction of plant traits (G), climatic variability (E) and management act...
Cover crops have a high potential to manage weeds through competition for shared resources in tropical agrosystems. Assessing the abilities of large number different plant species compete with requires experiments pedo-climatic environments. Our study was based on set 10 trials including 46 cover performed from 2016 2018 three sites Reunion Island. aim identify and measure traits that maximize ...
The paper analyzes the influence of soil type and its agrochemical characteristics on morphological productive parameters different yarrow (Achillea millefolium L.) populations. At 8 locations following fertility were analyzed: pH (H2 O), (KCl), CaCO3 (%), humus total N available P2 O5 K2 O (mg 100 g-1 soil). From parameters, measured: plant height, number leaves, diameter head, from fresh abov...
