Background: Soybean [Glycine max (L.) Merrill] is an annual herbaceous leguminous grain crop which cultivated mainly for its oil and protein. The objective of the study was to determine effects plant density zinc added phosphorus fertilizer sources on soybean yield performance under different environmental conditions. Methods: A field trial executed in two sites during 2018/19 2019/20 summer pl...
Crop yield is a highly complex quantitative trait. Historically, successful breeding for improved grain yield has led to crop plants with improved source capacity, altered plant architecture, and increased resistance to abiotic and biotic stresses. To date, transgenic approaches towards improving crop grain yield have primarily focused on protecting plants from herbicide, insects, or disease. I...
MOUSSA, H. R., 2011. Low dose of gamma irradiation enhanced drought tolerance in soybean. Bulg. J. Agric. Sci., 17: 63-72 Drought stress is the main limiting factor of soybean production. However, no work has been done on how application of low-dose of gamma rays could help to overcome water deficits during critical stages of soybean development. Gamma rays at doses 0.0 and 20 Gray (Gy), from a...
Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...
Clavulanic acid is a ß-lactam antibiotic which has a potent ß-lactamase inhibiting activity. In order to optimize its production by the new isolate Streptomyces DAUFPE 3060, the influence of two independent variables, temperature and soybean flour concentration, on clavulanic acid and biomass concentrations was investigated in 250 mL-Erlenmeyers according to a 2(2) central composite design. To ...
Salt stress inhibits soybean growth and reduces gain yield. Genetic improvement of salt tolerance is essential for sustainable soybean production in saline areas. In this study, we isolated a gene (Ncl) that could synchronously regulate the transport and accumulation of Na(+), K(+), and Cl(-) from a Brazilian soybean cultivar FT-Abyara using map-based cloning strategy. Higher expression of the ...
Native strains of Bradyrhizobium japonicum were tested for their effectiveness on nodulation, crop yield and nitrogen fixation in soybean (Glycine max). B. japonicum strains were isolated from soybean root nodules collected from different agro-climatic regions of Far Western Nepal, viz. Dipayal (607 m asl), Dadeldhura (1097 m asl), Silgadhi (1209 m asl) and Bajura (1524 m asl). The strains were...
The present study was a part of a long time screening experiment that includeda high number of wheat landraces (Triticum aestivum L.) cultivated in Greece, andfocused on the agronomic point of view and the drought adaptation for some ofthese landraces. One of the most acceptable ways for the assessment of droughtresistance is the examination of yield and yield components in different waterregim...
The effect of tillage, crop establishment and weed management was studied on theperformance of wheat grown after soybean at New Delhi, India during 2010-11 to 2011-12.Sixteen treatment combinations involved 2 tillage, viz. conventional tillage (CT) and zero tillage(ZT), two crop establishment practices, viz. raised-bed and flat-bed and four weed management,viz. isoproturon + hand weeding, mesos...
salinity is one of the abiotic stresses and exploitation of heterosis could increase the crop yield and extend the stress tolerance, especially in salinity stress. in this research, a set of full diallel design involving 7×7 crosses from cultivars including flat, bam, ghods, roshan, arg, kavir and pishtaz were conducted in a randomized complete block design with three replications under both no...
