Effect of pesticides on Exopolysaccharide (EPS) production, antibiotic sensitivity and phosphate solubilization by Rhizobial isolates from Sesbania bispinosa in Bangladesh
Rhizobium spp. retains a symbiotic relationship with leguminous plants including Sesbania bispinosa by fixing N2 through nodule formation. Several researches suggest that Exopolysaccharides (EPSs) are required for nodule formation. Rhizobial growth parameters as well as the EPS production are affected by the presence of pesticides. The present investigation was performed using three different pesticides which were...

Entomocidal activity of some plant extracts against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae)
Entomocidal activity of ethanolic leaf extracts of four plant species namely Euphorbia balsamifera Aiton, Lawsonia inermis L., Mitracarpus hirtus (L.) DC. and Senna obtusifolia L. were evaluated in order to assess their protectant ability to stored sorghum against Sitophilus zeamais Motsch. The botanicals were applied to 20 g of sorghum grains at the rate of 25, 50 and 100 mgml-1, while no extracts was added to the...

Dynamics of weed biomass on yield and yield component stability of maize under various weed management strategies
Weed is a very significant enemy of crop production. Its density, diversity and the interaction complexes on the yield and yield component of maize cv “Quality protein” were investigated in the present study. The experiment was laid out in randomized complete block design (RCBD) containing five weed management strategies and a weedy check as treatments in 2015 and 2016. Data were collected on weed density,...

Genotype×environment interaction and stability analysis of soybean genotypes for yield and yield components across two locations in Nigeria
A multilocational evaluation of 20 soybean genotypes was conducted in two distinct locations (Nsukka in Derived Savanna agro-ecology and Jalingo in northern Guinea Savanna) of Nigeria in 2015 and 2016 cropping seasons. The main objective of this study was to assess the genotype-by-environment interaction (G x E) for specific traits such as number of pods, pod weight, seed yield and yield stability. The results revealed...

Evaluation of yield and yield components of some groundnut genotypes under rainfed condition in Mali using biplot analysis
Sixteen groundnut genotypes were evaluated under three different environmental conditions of Mali during 2015/2016 rainy season. The environments were Tioribougou, Djijan and Samanko affiliated at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). The experiments were conducted in a 2×8 alpha lattice with three replications. Within the environment, the main effect of a genotype was...

Biochemical characterization of four less exploited edible fruits in Congo-Brazzaville: Passiflora edulis f. flavicarpa, Aframomum alboviolaceum, Saba comorensis and Clitandra cymulosa
The aim of this study was to determine the biochemical characteristics (moisture, crude protein, crude lipids, ash, pH, titrable acidity, minerals and free sugars) of four popular edible fruits (Passiflora edulis f. flavicarpa, Aframomum alboviolaceum, Saba comorensis and Clitandra cymulosa), but less exploited. The pulp and seeds of P. edulis f. flavicarpa and A. alboviolaceum was also investigated in order to identify...
