Review of the pre and post harvest handling methods of apple fruit (Malus domestic)

Apple (Malus domestica) is a tree and its pomaceous fruit, of species Mauls domestic a Borkhin therose family Rosaceae, is one of the most widely cultivated tree fruits. The main objective of this reviewis to review postharvest handling of apple fruit with the following Specific objectives: to review preharvest factors that affect postharvest quality of apple fruit and review postharvest factors that affectquality of apple fruits. The factor that causes postharvest losses of apple fruits are ...

Effect Of Chickpea (Cicer Arietinum L.) And White Lupin (Lupinus Albus L.) On Phosphorus Mobilization From Minjingu Phosphate Rock, Soil Available N And Sorghum Yields In Various Cropping Sys

ABSTRACTSmallholder farming systems in Njoro are characterized by the application of sub- optimal rates or non-utilization of inorganic fertilizers due to their exorbitant prices vis-à-vis low financial returns from crops. Efficient application of natural materials in agro ecosystems, viz. the use of Minjingu phosphate rock (MPR) as a fertilizer is an attractive alternative to inorganic fertilizers, however, releases phosphorous slowly due to its low solubility. The use of the legumes apart ...

Factors Influencing Pig Production In Embu West, Embu County, Kenya

ABSTRACTTraditional/backyard pig production systems are found in the larger Western Kenya while commercial systems are predominant in Eastern and Central Kenya including Nairobi. The pig holdings in Coast and few in North-Eastern are commercial systems. The expansion and improvement of the market for pigs and pig products generally in Kenya may explain why pig- keeping is beginning to be found outside traditional pig-keeping areas.The objectives of the study were: 1) To characterize pig produ...

Characterisation Of Livestock Production Systems And Its Contribution To The Food Security In Kitui County, Kenya

ABSTRACTLivestock production is critical in poverty reduction through food security improvement and rural development. Demographic characteristics, agro-ecological zone and market structure influences the the different livestock production systems. In order to plan for suitable interventions by Kitui County to enhance livestock production, this study aims to identify and document existing livestock production systems,and assessed household vulnerability to food insecurity in identified livest...

Effects Of Intercropping Maize (Zea Mays) With Butternuts (Cucurbita Moschata) At Varying Butternut Population Levels On Maize Growth, Yield And Weed Supression

ABSTRACT Intercropping is a cultural technique which gives crops a competitive advantage on weeds therefore contributes to weed management. There is need to choose the plant population which results in weed suppression whilst not negatively affecting the component crops yield. The experiment was set in a Randomised Complete Block Design with 5 treatments which are sole maize crop, maize-butternut intercrops at butternut densities of (30%, 40% and 50% of maize population which is 111...

Response of Onion (Allium cepa L.) to Bulb Size at Planting and NPK 15:15:15 Fertilizer Application Rate in the Guinea Savannah Agroecology of Ghana

Studies were conducted during the 2013 and 2014 cropping seasons at the research field of the University for Development Studies, Nyankpala in the Northern Region of Ghana to determine the effects of bulb size at planting and NPK 15:15:15 application rate on growth and yield of onion. The NPK 15:15:15 was applied at the rate of 0 (control), 80, 165 and 250 kg/ha. Three different bulb sizes: small (2.5-3.5 cm), medium (4.5-5.5 cm) and large (6.5-8.5 cm) were used. The treatment combinati...

Comparative Study of the Emergence and Growth of Young Seedlings of Five Varieties of Pistachio (Pistacia Vera L.) of Syrian Origins

The present work is to study the emergence and growth of seedlings of five pistachio varieties that are: Batouri, Achouri, Neb-Djemel, Adjmi and Bayadhi. The study was conducted in a greenhouse temperature and photoperiod were controlled. The seeds are germinated in pots filled with peat without going through the damp cold stratification at a temperature of 4ºC. The results obtained showed that growth parameters (length and diameter of the plants) revealed significant tests while other p...

EVALUATION OF THE POWDER OF Piper guineense AND Pirimiphos-methyl FOR THE CONTROL OF COWPEA STORAGE WEEVILS (Callosobruchusmaculatus)

ABSTRACTThe insecticidal effects of Piper guineense and Pirimiphos-methyl was evaluated on cowpea. The treatments used were P. guineenseat 0.2, 0.4, 0.6, 0.8, and 1g as well as Pirimiphos-methyl at 0.1g per 20g of cowpea seeds, each laid out in Complete Randomized Design (CRD) in the laboratory. Results indicated that P. guineense at 1g   concentration   significantly   (P
