Capacity for research and outreach on climate change agricultural adaptation in the Faculties of Agriculture of Universities in southeast Nigeria

The study examined research and outreach capacities on climate change agricultural adaptation in the faculties of agriculture in southeast, Nigeria. One hundred and twenty (120) randomly selected academic staff of faculties of agriculture were used. Data were collected using questionnaire and analyzed by descriptive statistics. The results show poor investment in equipment (18.7%) and human capacity building (25.8%);...

Genetic characteristics and path coefficient analysis in ten groundnut varieties (Arachis hypogaea L.) evaluated in the Guinea Savannah agro-ecological zone

Nine improved varieties of groundnut developed at the Institute of Agricultural Research, Samaru and one locally cultivated variety were evaluated for their breeding potentials in the Guinea Savannah agro-ecological zone. Considerable variability was observed for basal stem diameter, biological yield, days to first and 50% flowering, plant height, number of leaves/plant, branches/plant and100-seed weight, showing a wide...

Evaluation of substrates for multiplication of bio-agent, Trichoderma viride

An experiment was conducted using locally available substrates to mass multiply Trichoderma viride on different substrates. Experiment was conducted during June to August for 2 years (2011 and 2012). Result revealed that sporulation was observed after 5 days of incubation in cowdung, followed by all other substrates after 7 days of incubation. Maximum sporulation (51.50 × 108 cfu g-1) was observed in cowdung on...

A case study of rooftop rainwater harvesting of Renavi village in Sangli District of Western Maharashtra: New approach of watershed development in India

The population in India is expected to stabilize around 1640 million by the year 2050, as a result, gross per capita water availability will decline from 1820 m3/year in 2001 to as low as ~ 1140 m3/year in 2050. Thus, the growing concern about water scarcity challenges us to think of alternative solutions to avoid the current problem of water scarcity. The micro-watershed development, which ensures availability of water...

Allelopathic impact of aqueous extracts of Eclipta alba L. on germination and seedling growth of Melilotus alba Medik.

Allelopathy refers to the beneficial or retardatory effect of one plant on another plant through the release of chemicals from plant parts by leaching, root exudation, volatilization, residue decomposition and other processes in both natural and agricultural system. Allelochemicals concentration in the producer plants may vary from each part. Allelopathic effect of different parts extract of Eclipta alba L. on seed...

Characteristics of a manganese-rich soil and metal accumulation in edible parts of plants in the region of Moanda, Gabon

Moanda region in Southeastern Gabon is rich in manganese (Mn) ores. This study aimed to determine the physico-chemical properties of cultivated and uncultivated soils and the metal content in edible parts of 9 plants cultivated in this area. The studied soils had a sandy loam clay texture. Cultural practices induced a significant acidification, decrease in fertility and loss of metals from soils. Mn contents in soils...

Comparison of site selection of suitable lands for performance of pressurized irrigation by geography information system (GIS) in Kerman Plain, Southeast of Iran

The different parameters such as water, soil and climate have an important effect in the decision making and performance of pressurized irrigation systems. The underground and surface water resources in per region have no unique quality and quantity. The Kerman Plain, which has about 7500 km2, is located in the Kerman Province. The irrigation of this plain is done with using the underground water resources which are...

Effects of soil types and nutrient levels on early leaf development of maize, bean and sunflower crops

Leaf area development at early stages of plant growth affects dry matter production because the former is the determinant for the amount of light intercepted, which then is used for photosynthesis. A pot experiment was conducted in a glasshouse to investigate the interacting effect of soil types and nutrient levels on leaf area and leaf dry weight at early development stages of maize, bean, and sunflower. The experiment...

Effects of fermented Indigo-Leaf (Indigofera tinctoria L.) extracts on yield and pest control in Chinese mustard and sweet basil

The purpose of this study was to investigate the impact on yields and pest control of extracts from fermented Indigo leaves (Indigofera tinctoria L.) on Chinese Mustard (Brassica chinensis Jusl var parachinensis (Bailey) Tsen & Lee) and Sweet Basil (Ocimum basilicum L.)  For Chinese mustard, comparing crop yields revealed that fermented indigo-leaf extracts of mixed (tea-coloured and blue), tea-coloured and...

Hydrogen peroxide pre-treatment for seed enhancement in Cotton (Gossypim hirsutum L.)

Seed germination and plant stand is a major problem in cotton especially under rain-fed cultivation. Various seed hardening treatments have been recommended in cotton for combating the moisture stress during germination. The role of H2O2 as a seed treatment for enhancing cotton seed performance has not been determined. The present study was therefore undertaken to study the effect of H2O2 on germination under moisture...

Reduction of soil water content fluctuations and soil temperature variations under retrievable drip irrigation

Wide soil water content and temperature variations affect crop yields for reasons ranging from rate of seed germination, seed development, to plant growth. This study aimed at evaluating the extent to which drip irrigation can reduce soil water content and temperature variations. An experiment was carried out in a 154 m2 glasshouse with Tottori dune sand of Japan. Two irrigation levels of 60 and 100% of...
