Sweet potato is a food and nutrition security crop in sub-Saharan Africa with low yields resulting from soil infertility. We examined the effects of nine fertilizer regimes on growth performance orange-fleshed (OFSP) white-fleshed (WFSP) sweet varieties two agro-ecological zones characterized by Andosol Nitisol soils. The treatments were: NPK20-10-10, NPK6-15-28, rice husk biochar (RHB), fast c...

Loss of neurons that express the neuropeptide hypocretin (Hcrt) has been implicated in narcolepsy, a debilitating disorder characterized by excessive daytime sleepiness and cataplexy. Cell replacement therapy, using Hcrt-expressing neurons generated in vitro, is a potentially useful therapeutic approach, but factors sufficient to specify Hcrt neurons are unknown. Using zebrafish as a highthroug...

In the West African sub-region, intercropping is a critical element in cowpea product profiles. This study aimed to investigate impact of with pearl millet on genetic correlations, heritability, and response selection. Thirty-five genotypes one variety were used create three cropping patterns: sole cowpea, 1:1 (one row cowpea), 2:4 (two rows four cowpea). Split-plot experiments conducted for tw...

in order to indicate the effect of duck's presence, anas platyrhynchos in paddy fields on rice (oryza sativa l.) yield, yield components and its effect on weed density, an experiment was carried out in baz ghaleh dezh village, located in sangar, guilan, iran in 2013. this experiment was performed based on factorial split-plot analysis conducted in a randomized complete block design (rcbd)....

Drought is an important yield-reducing factor for corn and soya bean which are the two major crops in the Delaware, Maryland and Virginia (Delmarva) region of the United States. Cowpea (Vigna unguiculata L. Walp.) is primarily grown in drier regions of the world where it is one of the most drought-resistant food legumes. Field experiments were conducted in which 10 genetically diverse cowpea ge...

Nitrogen (N) plays a vital role in the productivity of maize (Zea mays L). To investigate fertilizer effects N on yield and growth hybrid variety (Gorilla), experiment was carried out at research farm University Swabi, Pakistan, during summer 2017-18. Four levels (Urea, Urea + Farm Yard Manure (FYM), Compost, Poultry (PM)) were set present study. Randomized complete block design (RCBD) used wit...

The relationship between the sowing patterns and yield performance is a valuable topic for food security. In this study, novel belt uniform (BU) pattern was reported, field experiment with four winter wheat cultivars carried out over three consecutive growing seasons to compare dry matter accumulation, harvest index (HI), grain components under BU line dense (LD) [BU narrow (15 cm) spacing; wid...

Abstract Crop yield improvement during the last decades has relied on increasing ratio of economic organ to total aboveground biomass, known as harvest index (HI). In most crop models, HI is set a parameter; this empirical approach does not consider that only depends plant genotype, but also affected by environment. An alternative simulate allocation mechanistically, in LPJ-GUESS model, which s...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...
