in order to determine the effects of substitution of barley grain with dried citrus pulp (dcp) on eight lactating holstein cows with average body weight of 550 ± 50 kg and 75 ± 15 days in milk were allocated to 4 dietary treatments, which were diet; the control with 0% dried citrus pulp (dcp) and 15% barley grain, diet 2, 3 and 4 containing 5, 10 and 15% dcp and 10, 5 and 0% barley grain respec...

in rainfed areas of iran, cereal yields are low, variable and mainly as a result of inadequate and erratic seasonal rainfall and associated management factor, such as late sowing date (or late crop germination). in order to investigate the effects of single irrigation and nitrogen on bread wheat (triticum aestivum l. var. sabalan) a field experiment was conducted as split plot arranged in a ran...

Funnell-Harris, D. L., and Pedersen, J. F. 2011. Presence of Fusarium spp. in air and soil associated with sorghum fields. Plant Dis. 95:648-656. Sorghum grain, valuable for feed, food, and bioenergy, can be colonized by several Fusarium spp.; therefore, it was of interest to identify possible sources of conidia. Analysis of air and soil samples provided evidence for the presence of propagules ...

A field trial was performed to investigate the effect of municipal biowaste biochar (MBB) on rice and wheat growth, metal bioaccumulation, and greenhouse gas emissions in a rice paddy in eastern China. MBB was amended in 2010 before rice transplanting at rates of 0 and 40 t ha -1 in a field experiment lasting one cropping year. MBB soil amendment significantly increased soil pH, total soil orga...

Six cowpea genotypes (Danila, IT96D-772, IT90K-277-2, IT95K-1091-3, IT96D-740, IT96D-757) were intercropped with a local millet cultivar using four row arrangements (1:1, 1:2, 2:2 and 2:4 millet to cowpea rows) in a field experiment conducted at Minjibir near Kano in the Sudan savanna ecological zone of Nigeria during the 1999 and 2000 wet seasons. Cowpea genotypes and row arrangement had no ef...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...

Winter wheat is threatened by drought in the Huang-Huai-Hai Plain of China, thus, effective water-saving irrigation practices are urgently required to maintain its high winter wheat production. This study was conducted from 2012 to 2014 to determine how supplemental irrigation (SI) affected soil moisture, photosynthesis, and dry matter (DM) production of winter wheat by measuring the moisture i...

Despite the resurgence of parastatal marketing boards and strategic grain reserves over the last decade in eastern and southern Africa, there is little empirical evidence about how their activities affect smallholder input use and cropping decisions. This paper uses panel survey data from 1997-2007 on Kenyan smallholders to investigate the effect of Kenya’s National Cereal Produce Board activit...

agroecology emphasizes the use of organic materials in agriculture. the organic acids are important sources of organic materials. in order to study the effect of different levels of humic acid on yield and yield components of corn (zea mays l.) an experiment was conducted at research station, faculty of agriculture, ferdowsi university of mashhad, iran, during 2009. the experiment was conducted...
