An orchard survey was conducted to assess the nutrient status of nectarines in Lapseki district in Turkey. For this study, leaf and soil samples were collected from 28 nectarine orchards and necessary information was obtained about yield and fertilization. Soil samples were taken once a year at two depths of 0-20 and 20-40 cm. In view of the findings based on soil analyses the results are summarized below:

Agriculture sector contributes significantly to the national economy and S&T has played a significant role in increasing agricultural productivity over the years. An extensive agricultural research system with a widespread extension machinery and government policy has enabled the agriculture sector to respond to the increasing demand for agricultural produce. However, in recent decades the agricultural scenario has witnessed several challenges like declining farm profitability, depletion of natural resources, resurgence of new pests and diseases, global warming and climate change.

An original polarimetric experimental setup is used to pump and probe photosensitive films. Photo-induced behavior of Azobenzene Disperse one (AZD1) doped Poly(Methyl MethAcrylate) (PMMA) using both linear and circular polarized light is studied. The anisotropy is not erased by the circular polarization light. The circular polarization light combined with relatively long lifetime of the cis state in doped polymers appears as if it activate all transverse directions of the angular hole burning through the film inducing anisotropy.

The focus of attention has become a capricious area of research in educational science. It has become a standing concern in the field of academics, sports and life skills.  To cater to the need of the day, the in-hand study was taken up to re-emphasize and re-establish the validity of the numerical value of focus factor as assessed by Cognitive Ability Test which is already developed and standardized.  The research was carried in and around Chandigarh.

Jamun (Syzygium cumini Skeels.) is an under exploited indigenous fruit tree of India.The variations act as an important source and are a prerequisite for a tree breeder in breeding methods to improve a species. To collect the variability with the aim of selecting some superior types/strains a survey was carried out in Amritsar, Gurdaspur and Pathankot Districts, in which 25 seedlings of jamun were evaluated for their physical characteristics and biochemical composition during 2015-2016 respectively.

Hearing loss and deafness can develop during infancy or childhood or adolescence or during old age. Congenital hearing loss is relatively frequent and has serious negative consequences if it is not diagnosed and treated. Worldwide 360 million people living with disabling hearing loss. In this 32 million of these are children (<15 years of age). Children whose hearing loss is > 90 dB are considered deaf for the purposes of educational placement.

Participatory evaluation of seven desert banana varieties were carried out in Dello Menna district of Bale zone, South Eastern Ethiopia. The purpose of the study was to test the adaptability of different banana varieties in the study area. The study was undertaken in four sites, with treatments arranged in randomized complete block design with three replications. Both agronomic data and farmers preferences toward the varieties were collected and analyzed using Genestat statistical software and matrix ranking respectively.

The productivity of livestock in Ethiopia is low due to scarcity and fluctuating quantity and quality of feed resources. Identify and use of new potential feed resources such as indigenous fodder trees and shrubs (IFTS) could bridge the gap.  The present study was aimed to identify and evaluate agro-ecological and seasonal variations of nutrients as well as to estimate potential biomass yield of IFTS collected from low and mid altitude of Gambella region, south-western of Ethiopia.

The study was designed to test the effectiveness of the linkages between the main actors in the extension delivery system in Delta State. The study sampled 120 farmers. Two cells were selected from five extension blocks making a total of 10 cells and six each from contact and non contact farmers were randomly selected from each of the ten cells. All the 81 extension Administration operating in the Delta North ADP zone were sampled, while Ten (10) administrators were randomly sampled from two innovation centres at five per centre. Descriptive statistical tools were employed in the study.

Decisions on containment of potential Cu toxicity require an understanding of its behaviour in the soil. Two experiments arranged in a Randomized Complete Block Design (RCBD), with four replications, were carried out separately, to assess the distribution of Cu. The treatments were 0.00, 12.33, 18.50 and 24.70 g/m2. Two different soils, Gleyic Arenosol (Nta series) and Eutric/Dysteric Gleysol(Temang series) were used for the studies. The study showed Cu sorption increased with increasing soil organic matter (SOM) content.
