Abstract Various winter crops can be produced before soybean [ Glycine max (L.) Merr] in the Southeast United States, however effect of these on productivity and optimum maturity group to use following various remains unknown. This experiment was conducted five environments across North Carolina 2019 2020 understand crop (MG) productivity. Winter investigated included cereal rye ( Secale cereal...

in order to study the characters affecting grain yield of lentil, a randomized complete block design with three replications conducted at dryland research station of northern khorasan (shirvan) in year 2002-2003. during the growth season and after harvesting, number of days to emergence, days to 50 percent flowering, days to maturity, number of primary and secondary branches, small and big diam...

in order to study the effect of planting date, row spacing and seed rate on grain yield and protein yield of faba bean (vicia faba l.), a split factorial experiment based on the complete randomized block design with three replications was conducted at research station of rice research institute of iran (rasht) during 2008-2010 for two years. experimental treatments were planting date in three l...

Nitrogen balance in agroecosystems provides a quantitative framework of N inputs and outputs and retention in the soil that examines the sustainability of agricultural productivity and soil and environmental quality. Nitrogen inputs include N additions from manures and fertilizers, atmospheric depositions including wet and dry depositions, irrigation water, and biological N fixation. Nitrogen o...

to study the effects of applied nitrogen levels and wild mustard densities on the growth of wheat and wild mustard, a field experiment was conducted at re-search and experimental field of islamic azad university of ahvaz-iran. the effects of three nitrogen levels namely 90, 150 and 210 kg.ha-1 and four wild mustard densities such as 0, 5, 10 and 15 plants.m-2 were evaluated in split plot arrang...

Gluconacetobacter diazotrophicus PAL3 was grown in a chemostat with N(2) and mixtures of xylose and gluconate. Xylose was oxidized to xylonate, which was accumulated in the culture supernatants. Biomass yields and carbon from gluconate incorporated into biomass increased with the rate of xylose oxidation. By using metabolic balances it is demonstrated that extracellular xylose oxidation led N(2...

Bioenergy related land use change would likely alter biogeochemical cycles and global greenhouse gas budgets. Energy cane (Saccharum officinarum L.) is a sugarcane variety and an emerging biofuel feedstock for cellulosic bio-ethanol production. It has potential for high yields and can be grown on marginal land, which minimizes competition with grain and vegetable production. The DayCent biogeoc...

Application of inadequate quantities of fertilizers limits maize yield in Ghana. Experiments were conducted to determine the effect of Mucuna pruriens, Canavalia ensiformis, and soybean (Glycine max (L.) Merrill) on maize (Zea mays L.) grain yield under 4 mineral fertilizer N levels in a rotational system. The legumes were established in April of 1996 and 1997 at Ejura in the forest-savanna tra...
