Socio-personal characteristics of the respondents viz- age, education, farm experience, Size of family, herd size, land holding, annual income, extension participation, source of information, risk orientation, economic motivation was studied. A multistage, purposive and random sampling technique was selected for the study. The present investigation was carried out in North Gujarat. Three districts of North Gujarat viz., Banaskantha, Sabarkantha and Mehsana were purposively selected for the study.

The present study entitled “An Economic analysis of mushroom cultivation in Punjab” was conducted in Dehriwal and Tarsikka blocks of Amritsar district. The present study was planned to examine the cost-return structure of white button mushroom in Punjab. A total of 80 mushroom growers were interviewed randomly from Dehriwal and Tarsikka. Mushroom growers were divided into three categories on the basis of bed area spawned i.e., small (26), medium (40) and large (14) mushroom growers.

Rice, scientifically known as Oryza sativa, serves as a staple food for 17 countries in Asia, providing 20% of the world's dietary energy supply. Rice productivity is limited by biotic and abiotic constraints in India (Pathaket al. 2021). Among biotic stresses, rice blast disease caused by Magnaporthe oryzaeis the most important fungal rice disease causing enormous yield losses in different parts of the world (Annegowdaet al.2021). It can infect the rice crop at all stages of its growth, from nursery to grain filling stage under conducive environmental conditions (Panda et al.

A halitose está presente em uma grande parte da população, onde revela vários desafios e expectativas para os profissionais de saúde bucal. Este estudo teve como objetivo realizar uma revisão de literatura sobre o tema proposto baseados em artigos científicos.

Wheat (Triticumaestivum L) is second most important cereal crop of India after rice and it grown throughout the country. It is a major staple crop of India and their quality of grain is reduced through infection of different diseases, among them Karnal bunt (Neovossiaindica) is one of major pathogen. It is of high quarantine importance which restrict global trade of wheat between different countries.

Considering that the genetic improvement of orange trees usingdifferent scion-rootstock combinations requires extensive research, we aimed to evaluate the agronomic performance and fruit quality of32 native clones of sweet orange grafted onto ‘Cravo’lime and grown on for eight years. The cultivar ‘Aquiri’ orange was employed as control since it is currently recommended by Embrapa for cultivation in Acre.

The present study entitled “Studies on epidemiological parameters on disease development of purple blotch of onion [Alternariaporri (Ellis) Cifferi]” was conducted in the Division of Plant pathology, P.G. Department of Agriculture, Khalsa College Amritsar, Rabi 2022-23.Onion (Allium cepa L.) is major vegetable crop cultivated primarily as food and export worldwide.It contains various anti-inflammatory, anti-cholesterol, anticancer and antioxidant properties with phytochemicals such as ‘quercetin’.

Croplands contribute significantly to the global nitrogen oxide (NOx) emissions, ammonia (NH3) volatilization, as well as nutrient pollution in water bodies, which is directly related to global warming and affects water and air quality. This study investigates the nitrogen (N) balance of croplands used for wheat-maize rotation farming using field free-drain lysimeters and incubation experiments.

The field experiment entitled “Effect of sources and levels of silicon on growth and yield of garlic cv. Phule Nilima was conducted during Rabi with a view to study the effect of sources and levels of silicon on growth, and yield of Garlic. The present investigation was carried out in Factorial Randomized Block Design (FRBD). Fifteen treatments comprised of five levels of silicon (0, 50, 100, 150 and 200 kg Si ha-1) through three sources of silicon viz. Diatomaceous earth, calcium silicate and bagasse ash.

The response to the harmful effects of the droughts of the 1970s was effective by the Nigerien authorities and development partners. The latter have carried out actions aimed at combating environmental degradation in the most affected regions. In Tahoua region, these actions aimed to alleviate the land problem and access to natural resources of households, especially women who suffer from inequalities in inheritance and lack of freedom of action because of customs, traditions and cultures which weighheavy on them.
