Induced resistance in the nematodes control

Nematodes are serious problem, parasitizing plants and impairing the yields of various plant species, especially in tropical countries. Control of these organisms is complex and usually demands integrated management practices. One strategy that has attracted the interest of researchers is the use of resistance inducers. Resistance inducers or elicitors can take the form of a chemical compound or a live organism, whose...

A review of innate immunity of silkworm, Bombyx mori

Bombyx mori is an important economic insect for silk production. However, many kinds of pathogens cause serious economic loss every year during sericulture. B. mori lack an acquired immune system but have a sophisticated innate immune system against foreign microorganisms. The innate immunity system of B. mori is composed of humoral and cellular immune reactions, including production of antimicrobial peptides (AMPs),...

Nutritive values of the drought tolerant food and fodder crop enset

Enset (Ensete ventricosum) is a drought tolerant crop, traditionally grown in Ethiopia. It has many usages: food, fodder, fibres and traditional medicine. Being perennial, enset improves local climate and soil conditions. It could contribute to improved food security in several drought-prone parts of the world. The aims of this study were to reveal the amino acids of enset corm, which can be cooked as a root crop, and...

Quality of coffee produced in the Southwest region of Bahia, Brazil subjected to different forms of processing and drying

Coffee quality is vital for quoting prices, marketing and for the acceptance of the final product by the consumer market. Many factors can interfere with the quality of the coffee beans, especially those related to the stages of post-harvest, such as processing and drying. The objective of this study was to evaluate the influence of dry (natural) and wet (washed) processing, dried in an earthen yard and in a cement...

Tillage depth effects on nodulation, nitrogen fixation and yield of three soybean varieties in the Northern Savanna zone of Ghana

Most of the farmers in the Northern Savanna zone of Ghana cannot afford the required quantities of synthetic fertilizers to apply to their crops to increase their yields. The inclusion of legumes such as soybean in the cropping systems of the zone has been found to be one of the alternatives. In order to assess the yield and Nitrogen (N) fixed by three varieties of soybean as affected by four tillage depths, a field...

Growth of Pleurotus ostreatus in culture media based on formulated straw or grass

Mycelial growth strains of POS 98/38, POS 09/100, POS 09/101, and POS 09/102 of Pleurotus ostreatus were evaluated in culture media with various compositions based on extracts of substrates formulated with sugar cane bagasse together with straws and grasses, and with or without nitrogen supplementation. The evaluation was performed during incubation regularly with a ruler graduated in millimeters until total...

Effects of seasonal change in Osinmo reservoir on arginase and rhodanese activities in Clarias gariepinus Burchell and Heterotis niloticus Cuvier

This work reports the seasonal change and variation in the physico-chemical properties of the water in Osinmo reservoir in Southwestern Nigeria and the effects on tissue distribution of the metabolic enzymes, arginase and rhodanese are the two fish species (Clarias gariepinus and Heterotis niloticus) collected from the reservoir. This study was carried out to correlate the activities of the enzymes with...

Effect of pulsing with sucrose and silver thiosulphate complex on keeping quality of cut peony (Paeonia lactiflora Pall.) cv. “Sarah Bernhardt”

An experiment was carried out on cut flower Peony cv. “Sarah Bernhardt” to study the effect of pulsing with sucrose and silver thiosulphate on vase life and other parameters. In the trial, sucrose at 3 levels of concentration (0.00, 2.00 and 4.00%) and silverthiosulphate (STS) at 4 levels (0.00, 0.50, 1.00 and 2.00 mm) were tested alone as well as in combination. The experiment was laid out in completely...

Performance of Arsi-Bale kids supplemented with graded levels of pigeonpea in dry season in Mid Rift valley of Ethiopia

Free grazing/browsing Arsi-Bale kids in dry season were supplemented with different levels of dried pigeon pea (Cajanus cajun) leaves to study its effect on weight gain. Kids browsed freely (PP0), and/or supplemented with 66 g (PP66), 99 g (PP99) and 132 g (PP132 PP) of sun dried pigeon pea leaves. Supplementation significantly (P<0.05) increased average daily gain of kids but there was no significant...

Irrigation withholding time management in four rice varieties at Guilan paddy fields (North Iran)

In order to determine the best irrigation withholding time in four varieties of rice, an experiment in factorial statistical format based on complete randomized block design was conducted. This experiment took place in National Rice Research Institute situated in Rasht township (Guilan province, North Iran) in 2008. First factor included four rice varieties (v1 = Khazar, v2 = Sepeed Roud, v3 = Hassani,...

Variability and trait association in culm and grain yield characteristics of recombinant inbred lines of Eragrostis tef × Eragrostis pilosa

A study was conducted to assess variability and association in some culm and grain yield characteristics of recombinant inbred lines of a cross between Eragrostis tef and Eragrostis pilosa. A total of 81 lines were evaluated using randomized complete block design at Akaki and Debre Zeit, Ethiopia in 2007. Analysis of variance indicated that there exists difference among the recombinant inbred lines of...
