In Vitro, in Vivo and in Field Sensitivity of Venturia inaequalis to Anilinopyrimidine Fungicides with Different Types of Scab Management and Degree of Control

Riccardo Fiaccadori
The sensitivity of Venturia inaequalis to anilino-pyrimidine (AP) fungicides (pyrimethanil and cyprodinil) was studied on populations sampled from apple trees with different fungicide and APs histories: 1) apple trees in uncultivated areas never exposed to fungicides (wild types), 2) commercial orchards with many years of good scab control with APs (well-controlled); 3) populations in experimental Centre where an initial good acti

DNA Fingerprinting and Assessment of Genetic Diversity among 22 Cowpea [Vigna unguiculata (L.) Walp] Varieties Grown in Ghana

Benjamin A. Danso, Daniel K. Dzidzienyo, Ruth N. A. Prempeh, Marian D. Quain
Identification of varieties based on only morphological traits is limited by the influence of environment on such morphological traits. Deoxyribonucleic acid (DNA) fingerprinting offers an efficient system of identifying varieties at the DNA level without any environmental interference. This work used 20 Simple Sequence Repeat (SSR) markers to characterise twenty-two cowpea [Vigna unguiculata (L.) Walp] varieties for the purposes

Ten Percent Farm Tree Cover

Dickson N. Mukunga
Small scale farmers in arid and semi arid areas are working hard to be able to get output on their farms in the changing climate patterns. These patterns are characterized by short irregular rains and long drought spells. In order to mitigate climate changes there is need to plant trees. Trees trap carbon from atmosphere, trimmed to provide mulch and decompose to become manure. Data were collected through face to fa

Influence of the Use of Capsaicin on the Storage of Rice Grain

Rasoazanakolona Voahanginirina
The storage of milled rice requires monitoring to achieve the goal promoted for its consumption: preserving the quality to feed effectively. Sometimes, however, contamination infiltrates under an atmosphere favoring the formation of weevils. A futile loss is created by the unexpected degradation. The effect of capsaicin on whitened rice Sitophilus o. weevils was

Effect of Foliar Applied Urea on Growth and Yield of Sunflower (Helianthus annuus L.)

Rajesh Kumar Oad, Muhammad Ali Ansari, Jagdesh Kumar, Dilpat Rai Menghwar
A field study was carried out during 2012-13 at Sindh Agriculture University, Tandojam, Pakistan, geographically latitude 25°N and longitude 68°E, to assess the effect of foliar applied urea on the growth and yield of sunflower. The experiment was laid out in a three-replicated Randomized Complete Block Design. Five treatments were tested against sunflower variety Hysun-33 which included: T1

Efficacy and Cost-Benefit Analysis of Indigenous Technical Knowledge versus Recommended Integrated Pest and Disease Management Technologies on Common Beans in South Western Uganda

Peace Kankwatsa
The common bean is the second most important food and third economically important crop after banana and coffee in the South Western Agro-Ecological Zone of Uganda. Farmers’ returns to investment in bean production are consistently negative mainly due to losses resulting from collective effects of insect pests and diseases that cause damages at the various plant growth stages. This research study was carried out to 1) identify the

Effect of Striga Trap Crops and Nitrogen Fertilizer Application on Yield and Yield Related Traits of Sorghum [Sorghum bicolor (L.) Moench] at Fedis District, Eastern Ethiopia

Fikadu Tadesse, Tamado Tana, Jemal Abdulahi, Fuad Abduselam
Striga causes a serious threat to successful cultivation of sorghum in areas of low and erratic rainfall and poor soil fertility. Therefore, to reduce yield losses and severity of Striga, a field experiment was conducted during the cropping season of 2015 on heavily Striga

Submergence Tolerance in Irrigated and Rainfed Lowland Rice Varieties: Agro-Morphological Basis for Rice Genetic Improvement in Southern Benin

Magloire Oteyami, Espérance Codjia, Clement Agbangla, Leonard Ahoton, Carline Santos, David Montcho, Antoine Missihoun
Objective: The study was carried out, on the rice perimeter of Southern Benin, to evaluate the response of irrigated and lowland rice varieties to the complete and partial submergence using agro-morphological traits. Method: Thus, 15 rice varieties were submerged in the field during 60 days according to split plot experimental design with two factors and three replications. Agro-morphological parameters such as plant height, numbe

Effects of Integrated Nutrient Management on Potato (Solanum tuberosum L.) Growth, Yield and Yield Components at Haramaya Watershed, Eastern Ethiopia

Abdulaziz Mohammed, Muktar Mohammed, Niguse Dechasa, Fuad Abduselam
Potato is an important food security and cash crop in eastern Hararghe Zone. However, the productivity of the crop is constrained by low soil fertility and poor fertilizer management practices. Therefore, a field experiment was conducted at Haramaya watershed in Haramaya District, Eastern Ethiopia; during the 2014 off season using irrigation. The main objective of the study was to assess the effects of integrated nutrient manageme
