Analysis of relations between Agriculture, Economic Growth and Environment in Algeria, Empirical Study (2000-2022).

Paper ID- AMA-26-11-2023-12742

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

Paper ID- AMA-24-11-2023-12741

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.

Suppressive effects of maize rhizospheric fungi on Rhizoctonia solani f. sp. sasakii inciting banded leaf and sheath blight

Paper ID- AMA-16-11-2023-12733

We employed the classical microbiological methodology to isolate endophytic fungi inhabiting the rhizosphere of maize (Zea mays L.). Identification of these endophytic fungi was carried out using ribosomal DNA sequencing, aiming to uncover distinct distribution patterns of these organisms that persist asymptomatically within the healthy root tissues of maize plants. The dominant fungal species associated with the roots of the maize hybrid PHM-1 were Aspergillus niger, Aspergillus terreus, Cladosporium cladosporidies, Penicillium oxalicum, and Penicillium raperi. To assess their potential impact, an in vitro assay was conducted to evaluate these isolates against Rhizoctonia solani f. sp. sasakii, the causal agent of banded leaf and sheath blight (BLSB). This disease is particularly prevalent in tropical regions worldwide and poses a significant threat to maize cultivation. Notably, the Aspergillus and Penicillium complexes found in the maize rhizosphere exhibited promising efficacy in inhibiting this soil-borne disease affecting maize plants.

Influence of anther pretreatment on the efficiency of haploid production in marigold (Tagetes erecta L.)

Paper ID- AMA-15-11-2023-12731

Varied types of pretreatments cause stress on microspore bearing anthers which induces change of the development pathway of microspore from gametophytic to sporophytic which in turn leads to the production of haploids. In our experiments different pretreatments were given to anthers of marigold before in vitro culturing of male gametophytes. Flower buds (of size 2-2.5cm) in which a majority of microspores had reached the mid- or late-uninucleate stage were tested with regard to the effect of cold pretreatment at 4°C for 3, 6, 9 and 12 days and starvation in 0.3 M mannitol solution for 2, 4, 6 and 8 days. Chilling at 4°C for 9 days resulted in highest percent of responding anthers (91.5%), highest percent caulogenesis (54.7), highest number of shoot buds per anther (7.2), highest number of regenerants per anther (5.5), lowest number of days taken for callusing (12.25) and lowest number of days taken to shoot bud induction (15.75). while starvation of anthers by using 0.3M mannitol solution for 4 days resulted in highest percent of responding anthers (81.75%), lowest number of days taken for callusing (11.75), highest percent caulogenesis (66.5%), lowest number of days taken to shoot bud induction (15.25), highest number of shoot buds per anther (7.25) and highest number of regenerants per anther (5.75). Among the two pre-treatments evaluated, cold pretreatment showed better results in terms of percent responding anthers while mannitol starvation was found best for percent caulogenesis.

Crop establishment method and weed management practice influences weed prevalences, crop growth and yield of maize in maize-wheat-greengram cropping system

Paper ID- AMA-15-11-2023-12726

Weeds are considered to be a major biotic constraints in crop production. Under conservation agriculture (CA), non-inversion of soil, retention of previous crop residues, and crop diversification alter the weed dynamics. Although, it supports sustainable crop production by enhancing soil health. Long-term adoption of CA may help in establishing perennial weeds. Therefore, a field experiment was carried out to assess the feasibility of crop establishment methods and weed management practices in maize during the rainy season of 2021 and 2022. The experiment was laid out in a split-plot design with three replications. The main plot comprised two crop establishment methods, conventional tillage (CT) and zero tillage (ZT) and four weed management practices [weedy check, recommended herbicide (RH), integrated weed management (IWM), herbicide rotations (HR)] in maize-wheat-greengram cropping system. The results revealed that ZT exhibited lower weed density (89.5 and 72.9 no. m-2, respectively) and biomass (62.6 and 42.9 g m-2, respectively). Among the weed management practices, HR recorded the lowest weed density (43.8 and 29.8 no. m-2, respectively) and weed biomass (34.1 and 19.4 g m-2, respectively). Lower weeds under ZT, encourages plant growth and it became (1.9 and 2.7%, respectively) taller and (22.2 and 18.9%) heavier over CT. Imposition of herbicides in rotation also provided good weed control, thus, obtained taller and heavier plants in both the years. The findings also showed a strong negative linear relationship between weeds and grain yield. Regression analysis between yield attributes and yield showed a positive linear relationship. Growing maize under ZT obtained higher grain and straw yield with 6673 kg ha-1 in 2021 and 5765 kg ha-1 in 2022, while straw yield was 11366 kg ha-1 and 9319 kg ha-1, respectively. Imposition of weed management with rotating herbicides exhibited significantly higher grain yield (7815 and 7031 kg ha-1, respectively) during both the years, however, straw yield was higher in HR (12163 kg ha-1) in the first year, and in the second year it was higher with IWM (10587 kg ha-1). Based on the experimental findings, maize can be grown under ZT with either HR or IWM for effective weed control, better crop growth, and higher yield in maize-wheat-greengram system.
