Effects of irrigation regimes at different growth stages on seed yield and yield components of two soybeans (Glycine max L. (Merr.)) varieties in semi-arid conditions
Water stress is the most limiting abiotic stress factor for soybean growth, development and production in semi-arid regions. The development of new soybean cultivars with high efficiency and ability to drought resistance is very important. Field experiment was conducted to investigated the impact of irrigation regimes at different growth stages (Full irrigation, irrigation regimes at vegetable growth, flowering, and pod...

Effect of biochar on soil physical properties, growth parameters and yield of soybeans on a five-year fallow
The potential of biochar as a soil amendment in agricultural fields is a recently recognized and yet underutilized technology. The objective of this study was to investigate the mid/long-term effects of a single biochar application on soil physical properties, growth parameters and the yield of soybeans in a sandy clay loam. Biochar was added to a highly weathered tropical soil at rates of 40 tons ha-1 five years prior...

Agronomic efficiency and grain yield response index of wheat varieties as influenced by nitrogen rates in semi-arid zone of southern Niger
Wheat productivity in southern Niger is hampered by the utilization of local wheat varieties that exhibit a low response to fertilizer. A field experiment was conducted over two dry seasons in Djirataoua to investigate the efficiency and responsiveness of four wheat varieties under four nitrogen doses (0, 100, 150 and 200 kg N ha-1). The experiment followed a split-plot design with three replications. Results revealed...

Screening sorghum local landraces for potential drought tolerance stay-green quantitative trait loci (QTLs) sources in Burkina Faso
Sorghum serves as a staple food for rural populations in Burkina Faso, but its cultivation faces limitations due to post-flowering drought stress. Consequently, there is a need for improvement to enhance resilience to moisture stress. The current investigation aims to identify drought-tolerant germplasm to enhance local susceptible elite varieties. One hundred and ten accessions, comprising improved and exotic...

Growth promotion and yield attribute improvement of five groundnut (Arachis hypogaea L.) varieties by the application of plant growth promoting rhizobacteria
The aim of this investigation was to evaluate the symbiotic performance of a collection of ten plant growth-promoting rhizobacteria (PGPR) strains on the growth and yield attributes of five groundnut varieties. The screening was conducted in the greenhouse using seeds of the varieties Essamay, Amoul Morom, 55-437, Fleur 11 and Sunu Gaal grown in 1.5 kg pots with Sangalkam soils. Leaf chlorophyll content, plant height,...
