Heifer performance, diet composition, and forage composition were compared during rotational and continuous grazing of mixed pasture (alfalfa, tall fescue, orchardgrass). One hundred eighteen yearling heifers were used to compare the three grazing systems during 2 yr. Treatments included continuous (CONT), 6-paddock rotational (6-PADD), and 11-paddock rotational grazing (11-PADD). Rotational pa...

A web-based model was used to simulate the impact of aeration on population growth of the lesser grain borer, Rhyzopertha dominica (F.), and the rice weevil, Sitophilus oryzae (L.), in stored rough rice, Oryza sativa L., at Beaumont, TX. Simulations were run for each of 10 yr with 1 August as the start date; 31 December as the end date; beginning populations of 2.5 adults per metric ton (1000 k...

In organic potato cultivation technologies, various biopreparations are used, which have a considerable impact on both the growth and development of crops, soil fertility indicators, is especially important for sod-podzolic soils characterised by low potential fertility. The purpose study to establish changes in humus content mineral nitrogen sod-mediumpodzolic loam under influence decompositio...

Several studies have suggested that geostatistical techniques could be employed to reduce overall transactions costs associated with contracting for soil C credits by increasing the efficacy of sampling protocols used to measure C-credits. In this paper, we show how information about the range of spatial autocorrelation can be used in a measurement scheme to reduce the size of the confidence in...

Biofuels derived from low-input high-diversity (LIHD) mixtures of native grassland perennials can provide more usable energy, greater greenhouse gas reductions, and less agrichemical pollution per hectare than can corn grain ethanol or soybean biodiesel. High-diversity grasslands had increasingly higher bioenergy yields that were 238% greater than monoculture yields after a decade. LIHD biofuel...

In the present study, we assessed the agro-industrial performance of 22 sugarcane genotypes adaptable to edaphoclimatic conditions in production microregions in the State of Pernambuco, Brazil, and we recommended the commercial cultivation of select genotypes. The variables analyzed were as follows: sucrose percentage in cane juice, tonnage of saccharose per hectare (TPH), sugarcane tonnage per...

The inherent problems associated with inorganic fertilizer such as scarcity and high cost informed the invention of cocoa pod husk based organic fertilizer. The impact of the fertilizer on cocoa output is hereby investigated in this study. The study was conducted in Cross-River State, Nigeria and purposive random sampling technique was used to select fifty cocoa farmers including the user and n...
