FACTORS INFLUENCING OLIVE PRODUCTION FOR SUSTAINABLE DEVELOPMENT IN ARID ENVIRONMENTS OF ALGERIA
This study delves into uncovering the intricate correlations between diverse factors and olive production yields within the El Oued region, focusing on two distinct time frames : 2000 to 2010 and 2011 to 2021. Employing Pearson correlation coefficients as the analytical tool of choice, we explored the interrelationships between key variables namely, the average agricultural land area, land area specifically allocated for olive cultivation, quantities of utilized manure and fertilizer, average counts of temporary and permanent workers, and the average irrigated agricultural land area—against the backdrop of the average yield of olive cultivation. The outcomes of our investigation unveiled a spectrum of correlation strengths, encompassing both positive and negative associations, for each respective time period. These revelations underline the dynamic nature of the relationships between the examined factors and olive production yields, shedding light on potential influences shaping these agricultural outcomes. To unravel the complex interplay between these variables further, this study employed advanced statistical techniques. Multiple linear regression models were developed to tease apart the contributions of individual variables and their collective impact on olive yields. In parallel, a sophisticated random forest model was also harnessed, offering a comprehensive understanding of intricate interactions within the dataset. The culmination of our efforts yielded invaluable insights into the multifaceted determinants underpinning olive production within the El Oued region. By discerning the nuanced relationships between these factors and their cumulative effects on yields, our findings hold significant promise for enhancing agricultural practices and elevating productivity levels. This research contributes not only to the theoretical realm of agricultural science but also holds practical implications, potentially guiding future strategies to optimize olive cultivation in the El Oued region.
Role of Kangayam cattle towards the livelihood of the farmers of Western agro – climatic zone of Tamil Nadu.
The present study was conducted in Western agro – climatic zone of Tamil Nadu with an objective to study the role of Kangayam cattle towards the livelihood of the farmers. Snowball sampling technique was pursued to select 200 Kangayam cattle farmers as respondents for the study. The contribution of Kangayam cattle towards the livelihood of the farmers were ascertained using semi – structured interview schedule supported with informal discussion and non –participant observations and the data thus collected was analyzed by using appropriate statistical methods. Results revealed that majority of the respondents (69.00 per cent) earn income through sale of milk produced by their Kangayam cow, one - third of the respondents (33.00 per cent) did not utilize their Kangayam cattle for work purpose and all the respondents (100.00 per cent) earned income through sale of farm bred Kangayam cattle. Nearly one - half of the respondents (47.50 per cent) had an annual income between Rs.58, 001 to Rs.83, 000 from their Kangayam cattle and fell in medium category and one - half of the respondents’ family (44.50 per cent) had consumed medium quantity (1000 ml –1750 ml) of Kangayam cow milk thereby consuming medium quantity of milk protein (32.80 g – 57.40 g), milk fat (41.00 g – 71.75 g) and milk calcium (1200 mg – 2100 mg). With respect to quantity of farm yard manure obtained from the Kangayam cattle, more than one-half (50.50 per cent) of the respondents was found to be in low category with nutrient contribution of Kangayam cattle to the farm land (1.82 tons to 5.77 tons per year), quantity of Nitrogen (14.56 kg to 46.16 kg per year), quantity of Phosphorus (7.28 kg to 23.08 kg per year) and quantity of Potassium (29.12 kg to 92.32 kg per year. On an average 235.425 employment days were generated through rearing Kangayam cattle in a respondent’s family per annum. The Kangayam cattle played an important role in the livelihood of most of the respondents (81.50 per cent) as a means of security during the economic crisis conditions like crop failure, hospital expenditures, educational need, marriage, repayment of loans etc., either through draught power or sale of milk or through sale of cattle mainly male calves, bullocks / bulls in the local markets to generate income. Since, Kangayam cattle play an important role in the livelihood of farmers and substantially contributing to the household income, nutritional status, fertilising their agricultural field, satisfying their prestige and status and acts as a security measure during uncertainties. Hence, promoting Kangayam cattle farming as a viable economic enterprise not only improves the economic and social status but also improves the soil fertility and agricultural productivity.
Exploring FTIR Spectroscopy as promising tool for Analyzing Cancer Biomarkers: A Comprehensive Review
Fourier Transform Infrared Spectroscopy (FTIR) has emerged as a powerful tool in the analysis of biomolecular changes associated with various types of cancer. This article provides a theoretical overview of the principles of FTIR spectroscopy, its application to the analysis of cancer biomarkers, comparison between healthy and suspected individuals available in the literature, methodological considerations, clinical implications, and future directions. Here we highlight the importance of early cancer detection using FTIR spectroscopy, with emphasis on the different biomarkers that can help in the detection of different types of cancer. We focus in this study on key biomarkers such as EGFR, ALK and ROS1.
GROWTH AND VIGOUR ASSESSMENT IN SEEDLINGS OF LESSER KNOWN TREE SPECIES- Mallotus philippinensis (Lam.) Mull. Arg. OWING TO BIOFERTILIZERS
Biofertilizers were used in the present trial to assess the influence on seedling growth, vigour and survivability of Mallotus philippinensis. M. philippinensis is a lesser known tree with numerous commercial benefits. The production of quality planting materials of the tree species in short duration is a genuine problem due to seed dormancy, very slow growth rate and survivability of seedlings in the early stage. For the production of quality seedlings in a shorter period, the present investigation was carried out, which comprised of seven treatments with biofertilizers (applying @ 10 ml plant-1) viz., Control, Azotobacter, Azosprillum, Acetobacter, Pseudomonas, PSB and VAM, laid out in completely randomized design. Among the various biofertilizer treatments, maximum shoot height (21.47 cm), collar diameter (4.91 mm), number of leaves (4.23) and total leaf area per plant (150.20 cm2) were recorded in Pseudomonas, Acetobacter, Azotobacter and Azospirillum respectively. Moreover, PSB recorded at par value for shoot height with Pseudomonas, for collar diameter with Acetobacter and for number of leaves with Azotobacter. Additionally, maximum total fresh weight of plant (5.75 g) and dry weight of plant (2.29 g) were recorded in PSB. In the seedling vigour attributes, the lowest sturdiness quotient of 4.23 was observed in control treatment and the maximum root: shoot ratio of 1.88 was recorded in pseudomonas. The important vigour index, seedling quality index recorded highest of 0.46 with maximum survivability percentage of 94.70 per cent in PSB. Thus PSB @ 10 ml plant-1 treatment was the overall better performer in growth, vigour and survivability of seedlings of lesser known but commercially important tree species M. philippinensis and can be utilised for production of quality seedlings in large scale.
Study the structure of cork oak forests and macroscopic characterization of cork in thePark National of Theniet-El-Had(North-WestAlgeria).
The cork oak forest, a defining feature of the Mediterranean region, is renowned for its cork production, a commodity of substantial industrial significance. This study aims to elucidate the structure of cork oak stands in Theniet-El-Had National Park and to characterize the cork they produce. To achieve this, 40 temporary plots were established, facilitating the sampling of 390 cork oak trees across two cantons (Sidi Abdoun and Ourten). Analysis of the distribution of various dendrometric measurements reveals that these cork oak forests form stands with an irregular structure. The growth in circumference and height varies significantly with concave topography, which allows for better water accumulation, and moderately inclined terrain, which provides improved drainage. Additionally, the characterization of cork growth from the sampling units (60 calas) reveals an average increase of 2.58 mm/year. The results of the cumulative growth study show that approximately 48% of the samples reached a thickness of 27 mm after 12 years, a satisfactory period considered as the rotation for the cork oak forest of Theniet-El-Had. Furthermore, the shape of the average cork growth curve is a regressive polynomial type, indicating a regular decrease and reflecting high-quality cork. The highest growth rates are recorded during the first three years, exceeding 3 mm/year. Beyond this period, the average growth rate falls below 2 mm, reaching 1.5 mm at the end of the eleventh year of growth. This study provides foresters with restoration, regeneration methods, and cork exploitation management tools.
