Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool season perennial grass that fills a critical forage produc-tion gap in the Southeast and is the predominant forage crop in much of the U.S. In fact, this species is the most widely used grass in improved U.S. pastures, occupying more than 36 million acres. Its popularity is related to establishment ease, drought tolerance, excellent graz...
The problem of concern in this project is that in the dry season following a lowland rice (Oryza sativa L.) crop, yields of post-rice crops are generally low, despite adequate water commonly being available in the soil pro®le to grow a potentially high yielding dry season (DS) crop without irrigation. Maize (Zea mays L.) yields are as low as 1 Mg haÿ1 or less, soybean (Glycine max L. Merr.) and...
Determination Of Amount Of Phosphate And Sulphate In Soil Samples From University Of Cape Coast Farm
The soil test analysis conducted by research on variety of crop growing soil gave values of 1220ppm of Phosphate which is regarded to be adequate for plant establishment and production. In the case of Sulphate, the experimental results obtained were as follows: virgin land (14.8ppm), tomato land (20.9ppm), cassava land (43.3ppm). Soil test analysis gave standard sulphate values required for gro...
The objective of this work was to evaluate the effect cover crops and fallow duration on onion crop planted in direct sowing trials carried out for three years. In year 2013, two field were sites. Two (oats millet) one uncovered control evaluated at planting dates. studied variables establishment dry matter cover. performed 2014 2015 length chemical oats evaluated. also laboratory Petri dishes....
Crop insurance is a viable solution to reduce the vulnerability of smallholder farmers to risks from pest and disease outbreaks, extreme weather events, and market shocks that threaten their household food and income security. In developing and emerging countries, the implementation of area yield-based insurance, the form of crop insurance preferred by clients and industry, is constrained by th...
Effect of seed ageing on stand establishment, growth and yield of three soybean varieties was studied. Treatments consisted of three varieties viz. Shohag, Bangladesh soybean 4 and BARIsoybean-5 with four levels of seed ageing viz. 20, 12, 8 and 2 months aged seed. Seed germination and field emergence percentage decreased but electrical conductivity of seed leachate increased with increasing se...
The study was conducted to evaluate the performance of thirty-six Basmati rice genotypes for yield and its related traits under direct-seeded (DSR), system intensification (SRI), chemical-free cultivation (CFC), conventional transplanted (TPR).The were evaluated two years at locations in randomized block design with three replications. Genotype Pusa 1121 scored highest ~22% increase method over...
Infection of crop species by parasitic plants is a major agricultural hindrance resulting in substantial crop losses worldwide. Parasitic plants establish vascular connections with the host plant via structures termed haustoria, which allow acquisition of water and nutrients, often to the detriment of the infected host. Despite the agricultural impact of parasitic plants, the molecular and deve...
