ABSTRACT Cadmium (Cd) is one of the most dangerous of soil pollutants because this heavy metal may easily move from soil to food plants through root absorption, and fairly large amounts can accumulate in their tissues without showing stress. The CEC increase from 175.554 to 105.331 and 95.502 respectively for decrease in concentration of cadmium metal, this is due to isomorphic substitution of the cadmium from the metal in cation exchange capacity (Ca, Mg, K and Na). Nitrogen also decreases b...
ABSTRACT Smallholder farmers are the major players in agricultural production and food supply systems in Africa. However, poor access to market limits their productivity growth. This brings into focus the need to support smallholders to become less subsistence-based and more entrepreneurial by tailoring production to market forces. Agriculture is one of Ghana's most important economic sector, employing almost half the population on a formal and informal basis and accounting for about 20% ...
Soil organic matter is the decomposed and partially decomposed remains of plants and animals in the soil and this help in nutrient recycling. This work evaluated the effect of compost types on various organic carbon fractions and microaggregation. Soil samples collected at 0-20 cm depth were analyzed for total organic carbon (TOC), free particulate organic carbon (fPoC), occluded particulate organic carbon (oPOC), acid-hydrolzable organic carbon (AHOC) and non-acid hydrolysable organic carbon...
The present study evaluated the silage characteristics and nutritive quality of panicum maximum ensiled with or without browse seeds. The study was a 7 x 2 factorial experiment, constituting of panicum maximum harvested at different maturity stages ensiled with two browse plant seeds (Enterolobium cyclocarpum and albizia saman) at different proportions(100:0, 75:25, 50:50, and25:75).Data o pH, Temperature and physical characteristics of the silage were recorded. There no significant (p
ABSTRACT A Field experiment was carried out to evaluate seventeen cowpea genotypes for yield components of seventeen cowpea genotypes that comprised of thirteen advanced breeding lines; IT99K-1060, IT97K-499-35, IT07K-299-6, IT99K-216-24-2, IT04K-333-2, IT98K-491-4, IT855K-643-1, IT89K-288, IT04-334-2, IT95K-2011-11, IT97K-573-1-1, IT0K-973-6, IT99K-1122 and four local accessions; Dan Cameroon, Dan Bauchi, Dan Wuri, Achishiru. The trial was conducted at teaching and research farm, Abubakar T...
ABSTACT This experiment was carried out at Bunda College Crops and soil Science Students’ Research Farm in the 2010/2011 cropping season with the objective to assess genotype improvement in terms of productivity and protein content in different soy bean genotypes. There were 12 inbred lines i.e., UG-5, TG X 1937-1F, TG X 1954-1F, TG X 1485-1D, TG X 1019-2EB, TG X 1830-20E, TG X1885-10E, TG X 1440-1E, TG X 1904-6F, TG X-1908-8F, TG X 1019-13F, TG X1019-14F and 4 cultivars i.e. Magoye, Naso...
ABSTRACT The impact of short term no-till cultivation on infiltration rate and dry aggregate stability in mararraban daware, Girei local government area, Adamawa state were evaluated to compare some soil properties as affected by some tillage operations. The no-till cultivation was started in June 2015 and in January 2017 measurements of soil infiltration rate, dry aggregate stability, pH (soil reaction), organic carbon, electrical conductivity (EC), and soil texture were made. Sixty (60...
Identifying genetic variation among some varieties of cassava for varied uses.
ABSTRACT A study of the effect of biochar (charcoal) on microbial colonization and heavy metal concentration in polluted soil was conducted for eighth (8) weeks between September to October, during the cropping season of 2018, at the faculty of Agriculture, Kogi State University, Anyigba. The aim of the study was to determine the effect of biochar on microbial colonization and heavy metal concentration in a polluted soil. The experiment was laid out in a completely randomized design (CRD) ...

The literature suggests there is ~0.3 percent chance per year of full-scale nuclear war. This event would have ~20 percent probability of causing U.S. mass starvation due to collapse of conventional agriculture from smoke blocking the sun. Alternate foods exploit fossil fuels (e.g. methane digesting bacteria) and stored biomass (e.g. mushrooms growing on dead trees) and are technically capable of saving all Americans from starving. However, current awareness is low and the technologies need t...
The sun could be blocked by an asteroid impact, supervolcanic eruption, or nuclear winter caused by burning of cities during nuclear war. The primary problem in these scenarios is loss of food production. Previous work has shown that alternate foods not dependent on sunlight, such as bacteria grown on natural gas, calories extracted from killed leaves, and cellulose turned into sugar enzymatically, could feed everyone in these catastrophes and preparation for these foods would save lives high...
This study was designed to establish farmers’ perception on climate change and weather variability and its impacts on input investments, crop yields and food security. The study was conducted in the Middleveld of Swaziland were three constituencies were selected within the region. Three communities were selected spatially from each constituency. Purposive sampling was used to select 30 households from each community to make a sample size of 270 households. Information was collected from hea...
This study was done to establish the appropriateness of government and NGOs strategies to improve food security through the production of drought resistant crops in Swaziland. To determine this, analysis was done on the current rural Swazi livelihoods, strategies used by subsistence farmers to cope with hunger, priorities of both subsistence farmers and change agents and the approach used by change agents to fight hunger. Sithobela community was picked as a case study and a total number of 72...
Several catastrophes could block the sun, including asteroid/comet impact, super volcanic eruption, and nuclear war with the burning of cities (nuclear winter). Previous work has analyzed alternate food supplies (e.g., mushrooms growing on dead trees, bacteria growing on natural gas). This was shown to be technically capable of feeding everyone with macronutrients (protein, carbohydrates, and lipids) and minerals, although economics and politics remain uncertain. The present work analyzes vit...
