The vermicompost using earthworms (Eisenia Fetida) was produced from food waste and chemical parameters (EC, pH, carbon to nitrogen contents (C/N)) and germination bioassay was examined in order to assess the stability and maturity indicators during the vermicomposting process. The seed used in the germination bioassay was cress. The ranges of EC, pH, C/N and germination index were 7.5-4.9 mS/c...

The timing of harvest is a major factor affecting seed quality in soybean, particularly in Midsouthern USA, when rain during harvest period is not uncommon. The objective of this research was to evaluate the effects of time of harvest on soybean seed quality (seed composition, germination, seed coat boron, and lignin) in high germinability (HG) breeding lines (50% exotic) developed under high h...

This study investigated the effects of applying psychrotrophic cellulose-degrading fungi on cellulase production, fungal community structure, and maturity pig manure (PM) compost under low-temperature conditions. Three strains were isolated identified, after cold-active production conditions optimized, they inoculated into PM compost. While control (CK) temperature failed to reach thermophilic ...

conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...

The goal of this study was to apply artificial neural networks to predict rain-fed wheat yield using meteorological data a few days to few months before harvesting. The climatic observation data used; were mean of daily minimum and maximum temperature, extreme of daily minimum and maximum temperature, sum of daily rainfall, number of rainy days, sum of daily sun hours, mean of daily wind speed,...

This study was undertaken with the objective of standardizing the protocol for the micropropagation of Albizia lebbeck (L.). Seeds were collected from three different colored pods (yellow, dark yellow and brownish yellow) harvested from field grown Albizia tree from November to January and were surface sterilized using different concentration of mercuric chloride (0.050.15 % w/v) for different ...

Limited information is known on the basic biology of the recently described Phytophthora kernoviae that produces homothallic oospores. In this study, different P. kernoviae isolates were used to investigate oospore maturity, germination, and infection. All isolates produced oospores in V8 broth at 20°C in the dark by 6d. Oospores also formed at 10 and 15°C, but did not form at 25 and 28°C. Cont...

A study of two cultivars of ‘egusi’ melon [Citrullus lanatus (Thunb.) Matsun and Nakai] known as bara and serewe, was undertaken at the Teaching and Research Farm of the University of Agriculture Makurdi in 2010. The aim was to study the effects of variable developmental stages and position of fruits on the mother plant on seed quality. Bulk crop was raised and fruits that developed from date t...

Introduction. Low seedbed temperatures at the planting and direct sowing method can reduce sweet corn germination. Transplanting may offer optimum environmental conditions for seed germination, early crop maturity, increase (Zea mays L. group saccharata) productivity. Boron deficiency depresses yield through male sterility. Objective. To evaluate effect of transplanting addition boron in produc...

Introduction. There is a practical interest in biofuels production from bioomass of perennial cereal grasses such as switchgrass, which characterized by relatively high yields, low water and fertilization demand, reliable productivity wide geographical area, reduced soil erosion, carbon sequestration improved wildlife habitat. The crop propagated mainly seeds, long dormancy period, leads to fie...
