Evaluation of highland maize at Bule hora District of Southern Oromia, Southern Ethiopia

In order to evaluate the performance of highland maize, an experiment was conducted at Bule hora district of southern Ethiopia by introducing five highland maize from Ambo Plant Protection Research Center and Bako Agriculture Research Center, during the main cropping season of 2010 and 2011. The experiment was carried out in a randomized complete block design with three replications. The data were recorded on plant...

Sunflower seed treatment with growth inhibitor: Crop development aspects and yield

Sunflower is one of the most important oleaginous crops designated for edible oil production in the world. However, Brazilian growers still do not have enough knowledge, and technical expertise, for expanding the sunflower crop yield through the adoption of new technologies, like the utilization of plant growth regulators (paclobutrazol). The aim of this work was to evaluate the effects of different doses (0, 50, 100,...

Nitrate and potassium leaching and the response of the common bean to different irrigation blades

The aim of this study was to determine the effects of increasing irrigation levels on the movement of nitrate and potassium in clay soil and on crop yields for the common bean irrigated by central pivot under Brazilian Cerrado conditions. The experiment was conducted in Urutaí, Goiás, Brazil, in Dystrophic Oxisol clayey soil in 2014. Four irrigation regimes were tested, which were equivalent to 50, 100,...

Performance of a water ram built with disposable bottles

The hydraulic ram is a device that makes use of the energy of a “water fall” to raise part of the water flow to a higher elevation by merely using the energy of the water hammer. Even though a small water volume is compressed, the device may be a solution for water supply on family farms, for home use, animal drinking troughs and watering of vegetables. Current study evaluated the performance of a hydraulic...

Estimation of the flower buttons per inflorescences of grapevine (Vitis vinifera L.) by image auto-assessment processing

The aim of this research is to develop a reliable tool by a special method, combining image processing based on watershed algorithm, and a predictive model to estimate automatically the flowers number per inflorescence. Eighty images of Vitis vinifera L. inflorescence (the Cardinal cultivar) were processed. Watershed algorithm was used for the image processing and this was followed by statistical analysis that provides...

Induction of genetic variability and plant development in palisade grass evaluated in M2 mutants

The objective of this study was to evaluate the induction of genetic variability and plant development of palisade grass (Urochloa brizantha L.) M2 mutants in acclimatization to subtropical climate condition. The mutagenic agent methyl methanesulfonate (MMS), at a dosage of 0.5%, was used to induce mutation in 4,000 seeds of the cultivar Marandu. Thirty five plants survived after the induction of MMS mutagen agent....

Physical and hydraulic properties of a Latosol influenced by land use and management changes

Changes to soil use can modify the soil’s physical and hydraulic properties, affecting its potential for productivity. This study aimed to characterize the physical and hydraulic properties of a clayey Dystroferric Red Latosol under the following land uses: conventional tillage (CT), direct drilling systems (DD), and native forest (NF). The study was conducted in Londrina (PR), Brazil, (23°23′ S,...

Economic evaluation of milk production in family farm, with cattle feed with soybean meal

Accounting can play an important role as a management tool, through information to enable planning, control and decision making, turning farms into companies with the capacity to monitor the evolution of the sector, especially with regard to the objectives and functions of financial management, cost control, crop diversification and comparison of results. Soybean meal, half-whole can be an excellent alternative to...

Nutritional status of soil and plant and nutrient discrimination factor of some irrigated olive orchards at the North West of Egypt

A study was conducted during 2014 to 2015 seasons on olive orchards; cultivars (Koroneki, Dolce and Manzanillo) grown on sandy soil under drip irrigation and irrigated with different levels of water salinity from 0.95 to 4.3dS/m-1, in various locations in Cairo-Alexandria road, to evaluate the nutritional status through soil testing and leaf analysis. The soils had very high pH and low organic matter, potassium, iron...

Yield and vigor of corn seeds under the influence of flooding periods

The aim of this work was to characterize the physiological performance and some of the yield attributes of maize seeds in response to periods of temporary flooding. The study was conducted in an experimental design of randomized blocks, with four treatments composed by four replications, being evaluated the germination, the first count of germination, the germination speed index, the thousand seed weight, the number of...

Forage yield components of various alfalfa (Medicago sativa L.) cultivars grown on salt-affected soil under rainfed and irrigated conditions in a Mediterranean environment

In Algeria, the area allocated to crop fodders in particular, the alfalfa (Medicago sativa L.) is very limited as compared to other crops. Some obstacles hinder the development of crops especially in irrigated perimeters. A field experiment was conducted to highlight the adaptation of sixteen (16) alfalfa varieties from different origins (Algeria, Australia, France, Italy, Morocco, Tunisia and USA) to drought, soil...

Agroclimatic risk of development of Diaphorina citri in the citrus region of Nuevo Leon, Mexico

Diaphorina citri is the insect vector of the disease, Huanglongbing (HLB) which is the most devastating citrus disease worldwide. It is necessary to identify potential risks; this can be done based on favorable thermo-pluviometrical conditions for the vector. The present study aims to identify potential risks in the Nuevo Leon citrus region in areas, which have not yet been devastated by the citrus disease. The presence...
