The cotton bollworm Helicoverpa armigera occurs as a major pest in many economically important crops, including cotton, pigeon pea, chickpea, cowpea, sunflower, tomato, sorghum, pearl millet and other crops. Intestinal microorganisms play role the degradation of diet components insects. In order to know gut bacteria insecticide resistance five insecticides Chlorpyriphos (20% EC), Cypermethrin (...

Combinations of winter and fall cover crops were evalu­ ated for the management of plant-parasitic nematodes. The winter cover crops examined were rye (Secale cereale) and narrow-leafed lupin (Lupinus angustifolius) and the fall cover crops were soybean (Glycine max), cowpea (Vigna unguiculata), sorghum-sudangrass (Sor­ ghum bicolor x S. sudanense), sun hemp (Crotalaria juncea), and corn (Zea m...

This study was conducted to evaluate the effect of varying levels of urea treated and untreated cowpea husk on the performance of weaned rabbit. Sixteen (16) breed weaner rabbits of both sexes, 6-8 weeks old with an average initial weight of 833g were randomly distributed to four dietary treatments with 4 rabbits per treatment. The experiment lasted for a period of six weeks. Two diets were for...

Abstract Wheat ( Triticum aestivum L.) production in Texas depends heavily on conventional tillage (CT) and a long summer fallow period, which contributes to soil degradation. This study compared the impact of reducing intensity (CT, no‐tillage, strip‐tillage) combined with cropping CT–summer wheat establishment, grain production, herbage mass from 2016 2020 three ecoregions (Coastal Plains, So...

1.1 Prevalence of abiotic stresses in SAT agriculture The semi-arid tropics (SAT) include parts of 48 countries in the developing world: in most of India, locations in south east Asia, a swathe across sub-Saharan Africa, much of southern and eastern Africa, and a few locations in Latin America (Fig 1). Semi-arid tropical regions are characterized by unpredictable weather, long dry seasons, inco...

In the present study the mould incidence, ergosterol and aflatoxin B1 (AFB1) contaminations were evaluated in different food based seed samples viz., chickpea, cowpea, green gram, groundnut, Indian bean, maize, sorghum, soya bean and sunflower collected from different agro-climatic regions of Karnataka (India). The agar plate and standard blotter methods were employed for determination of the f...

The seeds of parasitic plants of the genera Striga and Orobanche will only germinate after induction by a chemical signal exuded from the roots of their host. Up to now, several of these germination stimulants have been isolated and identified in the root exudates of a series of host plants of both Orobanche and Striga spp. In most cases, the compounds were shown to be isoprenoid and belong to ...

Since the 1980s cowpea has become an alternative cash crop in northern Senegal. However, in 1997, surveys showed that farmers often sold their crop at unprofi table prices. The hypothesis was that farmers could improve selling prices if they produced cowpea with the characteristics demanded by consumers. To identify those characteristics, data were collected in six markets from January 1998 to ...
