Weather forecast interpretation for improved agro-advisory for Cauvery Delta Zone of Tamil Nadu, India
Cauvery Delta Zone in Tamil Nadu is a significant area used for agricultural production, and its productivity is prominently influenced by weather. Farmers would find agro-services based on meteorological indicators to be beneficial. Interpretation and verification of weather forecast for Cauvery Delta Zone is the main subject of this study. Based on weather forecasts from the India Meteorological Department, advisory services were provided to seven districts in the Cauvery Delta Zone. Actual weather data collected at the Agrometeorological observatory of the Tamil Nadu Rice Research Institute, Aduthurai, was analysed to confirm the accuracy and validity of the weather forecast for 2022. Both qualitative and quantitative methodologies were used to analyse the anticipated weather factors. Simple success probability analysis of rainfall forecast, 2022 indicated that in all districts more than 90 % success rate was registered during winter and summer. Minimum success rate was registered during NEM in most districts. Maximum temperature probability analysis indicated that higher success percentage was registered in most districts during winter, 2022. During summer highest success rate was recorded in Thajnavur district. Monsoon season (both SWM and NEM) registered less success rate than the winter and summer season. Forecast accuracy of wind speed is very poor in all districts for all season. This indicates clearly that there is a need to improve forecast accuracy for wind speed. Results confirm that weather forecast is useful for the farmers but further improvement of forecast accuracy is needed.
Effect of different shade nets on growth, yield, and quality of Palak (Beta vulgaris var bengalensis)
A research experiment was conducted at Vegetable Research Farm, Punjab Agricultural University, Ludhiana during the summer and rainy seasons of 2021-2022 to study the effects of colour shade nets on different parameters of palak (Beta vulgaris var bengalensis). The experiment was set up in a split-plot design, with three replications, utilizing seven different coloured shade nets (red, blue, black, white, green with 50% and 70% shade level and open condition) in the main plot and seven distinct sowing times at monthly intervals from mid-April to mid-October in the sub-plot. From the results, it was examined that air temperature and light intensity were significantly lower under the various coloured shade nets in comparison to open conditions. The palak exhibited varying characteristics based on the conditions of shade nets. Specifically, the duration for germination (4.2 days), plant height (31.8 cm), leaf length (21.6 cm), leaf area (47.1 cm2), and overall yield (134.0 q/ha) were most pronounced when a green shade net with a 50% shading level was used. Whereas, dry matter content (10.5%) and chlorophyll concentration (8.75 mg/100g), showed improved results when a white shade net and red shade net were employed, respectively. The maximum cost-benefit ratio of 3.28 was achieved specifically in crops sown in August under a green shade net with a 50% shade level. Overall, it was observed that green colour shade net with 50% shade level may be recommended palak cultivation during summer months in Punjab conditions.
Empirical Study on the Factors of Agriculture Production Function in Algeria
Identifying key factors of the production function in agriculture allows better management of resources, promotes growth, and contributes to the development of effective economic policies. Thus, the objective of the study is to identify the key elements of the production function in agriculture, focusing on Algeria between 2000 and 2022. In order to achieve that, the Cobb-Douglass functional form is used. Also, the assessment of factor elasticities is carried out using multiple regression models. The study shows that agricultural production in Algeria depends on several factors. The multiple regression's final results indicate that the factors relating to the following account for 76% of the total agricultural production: employment, number of machines, agricultural budget, imports, foreign direct investment and renewable energy consumption. The variables used in the final model are significant at the 1% and 5% thresholds. When analysing the elasticities of selected factors, the study found increasing returns of scale during the analysis period.
Analysis of relations between Agriculture, Economic Growth and Environment in Algeria, Empirical Study (2000-2022).
The objective of this contribution is to analyze the existing relation-ships between agriculture, economic growth and greenhouse gas emissions in Algeria during the period 2000-2022. A Principal Component Analysis (PCA) was applied to the study data in order to assess the possible positive role of agriculture (as a brake on climate change) in reducing CO2 emissions. The results indicated that both agricultural land and forest area contributed more to the increase in CO2 than to its reduction. The Granger causality test was adopted to test the causal relationships between agricultural production and economic growth, and between agricultural production and greenhouse gas emissions (all gases combined). The results revealed the existence of a unidirectional relationship between agricultural production and greenhouse gas emissions, and the absence of a bidirectional relationship between agricultural production and economic growth. Algeria should develop sustain-able agricultural policies that reconcile economic growth with the reduction of greenhouse gas emissions.
Impact of Various Edible Coatings on the Physical Parameters of Guava (Psidium guajava L.) Fruits over Different Storage Periods
The research was conducted to extend the shelf life of guava fruits through individual and combined application of different edible coatings viz,: olive oil (100%), sesame oil (100%), tulsi leaf extract, aloe vera gel (100%), chitosan (2%), calcium gluconate (2%) and sodium alginate (2%) during 2020-2021 to 2021-2022. To evaluate the effect of different edible coatings on physical parameters on guava fruits during different storage period. The experiment was laid out in completely randomized block design comprised of 20 treatments with 3 replications. The result showed that all the edible coatings were significantly effective for enhancing the shelf life of guava fruits in both the year as well as pooled data over to control. Among the treatments, olive oil 100% + chitosan 2% was recorded significantly minimum physiological weight loss (1.43, 2.98, 5.54, 9.13, 11.02, 13.17 and 16.46 %), Decay/ Spoilage (1.78, 9.37, 13.77 and 16.10 %) and Marketable fruit retained (98.23, 90.64, 86.24 and 84.76 %) at 2, 4, 6, 8, 10, 12 and 14 days after storage respectively, which was at par with olive oil 100% + sodium alginate 2% and olive oil 100% + calcium gluconate 2 % as compared to other treatments in pooled analysis. Therefore, it is concluded that the edible coatings have to potential to extend the shelf life.
