623 Lowbush Blueberry Response to Phosphorus Fertilizers with Different P: N Ratios

Pollination Reservoirs in Lowbush Blueberry (Ericales: Ericaceae)

Pollinator-dependent agriculture heavily relies upon a single pollinator-the honey bee. To diversify pollination strategies, growers are turning to alternatives. Densely planted reservoirs of pollen- and nectar-rich flowers (pollination reservoirs, hereafter "PRs") may improve pollination services provided by wild bees. Our focal agroecosystem, lowbush blueberry (Vaccinium angustifolium Aiton),...

Anisotropic photocurrent response at black phosphorus-MoS2 p-n heterojunctions.

We investigate the photocurrent generation mechanisms at a vertical p-n heterojunction between black phosphorus (BP) and molybdenum disulfide (MoS2) flakes through polarization-, wavelength-, and gate-dependent scanning photocurrent measurements. When incident photon energy is above the direct band gap of MoS2, the photocurrent response demonstrates a competitive effect between MoS2 and BP in t...

Growth response and ion distribution of two canola varieties to different potassium to sodium ratios

Rapeseed (Brassica napus L.) is a crop relatively tolerant to salt. The effect of different ratios of NaCl/KCl was studied in two cultivars (Hyola308 and Kristina) of Rapeseed in 2002. Canola seedlings were grown in Hoagland’s solutions, which were salinized by different ratios of NaCl/KCl. The treatments or KCl:NaCl ratios were 0:0 (control);10:10; 20:0 (Total Added Salt or TAS=20 mol.m-3), 0:...

Growth and Yield Response of Maize (Zea mays L.) to Different Rates of Nitrogen and Phosphorus Fertilizers in Southern Nigeria

The effect of twelve different rates of nitrogen and phosphorus fertilizers on growth and yield of maize (Zea mays L.) in southern Nigeria was evaluated between June and October, 2007. The results of the study showed that application of 120kgN/ha + 0kgP/ha and 60kgN/ha + 40kgP/ha significantly increased the growth of maize than other treatments. The application rate of 120kgN/ha +40kgP/ha signi...
