A Field Experimental Thermal Evaluation of Green Facade using Different Native Plant Species for Hot &Humid Climate of Chennai

Paper ID- AMA-08-12-2022-11872

The destruction of horizontal greenery has resulted in the development of an innovative technique called verticalgreening. It is a technique to bring back the lost greenery on the facades of the building for its numerous benefits in building and urban scale levels. However, due to lack of awareness and technical knowledge, its adoption is restricted, with the majority of its application for aesthetic purpose. Though there are numerous researches conducted to evaluate the thermal performance of vertical greening across the globe, there are only few researches performed to examine the thermal performance of vertical greening in hot and humid climate of Chennai using native edible and herbal plants. Vertical greening is of two types, Greenfaçade and Living wall. In Green facade, vines grow using simple support system to cover the entire wall from the growing medium placed at the base level. In living wall, a complex structural system holds the growing medium and the plants parallel to the wall. The temperature reduction of the green facade is directly dependent on the leaves size, thickness and density while in the case of livingwall, temperature reduction is influenced by multiple factors such as the soil medium, supporting structure, and varieties of plantsused. Even though researchers have proved that living wall reduces more temperature than Green facade, this research aims to establish that temperature reduction of the green facade depends on the type of plant species and its foliage density. This research aims to explore the thermal performance of Green facade using two different plant species with different physical parameters. An experimental methodology was used to measure the surface temperature behind the Green facade along with which the indoor temperature and humidity was measured. The experiment was conducted on the terrace of a residence located in Tambaram, Chennai for three days from 22 -24th September 2022. Three small-scale test boxes were used. Two test boxes were treated with two different plants while one box was kept as a bare model (Benchmark) for the comparison. The study plants are Clitoria ternatea (butterfly pea) and Basella rubra (Indian spinach), both of which are native to India and most commonly seen in Chennai. These plants are chosen for their longer lifespan, low maintenance, fast growth, and heattolerance. The analysis and the findings of the research showed that the surface temperature behind the Basella rubra and Clitoria ternatea was reduced by 7deg c and 4 deg c. The maximum indoor temperature reduction for Basella rubra and Clitoria ternatea was 3.6 deg c and 2.4deg c proving that the thermal performance of Green facade in reducing the surface and indoor temperature differs depending on the plant species used. Denser the foliage with succulent leaves of Basella rubra showed more temperature reduction than Clitoria ternatea which had smaller leaves with thin foliage coverage.

Influence of Forage Radish Cover Crop on Growth and Yield of Vegetable Crops in an Intensive Vegetable Cropping System

Paper ID- AMA-07-12-2022-11871

Radish mostly forage radish (Raphanus sativus L.var. longipinnatus) cover crop (CC) being a short-duration crop can be easily incorporated into the vegetable cropping system for sustainable production of vegetable crops. In the present experiment, the incorporation of forage radish CC biomasses before and after the harvest of vegetable crops provided numerous benefits. Vegetative growth and yield attributing parameters in terms of plant height, branch number, average fruit number, average fruit weight, stem diameter etc. of okra, bitter gourd, chilli, dolichos bean, amaranthus and cowpea were found to be higher in CC treatment compared to bare fallow control devoid of CC. Among the different levels of CC used complete ground cover with cent percent CC recorded better in terms of growth and yield attributes compared to 75 and 50 percent surface cover. The yield of vegetable crops in the cropping system was found to be positively influenced by the levels of forage radish CC compared to the non-adoption of CC in the control. The crop duration of the vegetable crops was also enhanced by the use of CC compared to control devoid of CC, and the harvesting duration of vegetable crops was prolonged due to the use of CC. For sustainable vegetable crop production with 200% vegetable cropping intensity in the sandy soil of Gossaigaon, Assam, India forage radish CC (Raphanus sativus var. longipinnatus), syn. Daikon or Japanese radish can be used as CC before sowing spring-summer and summer season vegetable crops.

Pathogenicity and Toxicity of Metarhizium anisopliae (Metchnikoff) Sorokin against Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) under in vitro conditions

Paper ID- AMA-07-12-2022-11870

The Helicoverpa armigera, Hubner (Lepidoptera: Noctuidae), is the most important economic pest. In the larval stage, the pest feeds on tomato fruits and seriously damages the fruits. Therefore, to reduce the overuse of chemical pesticides in tomato crops, microbial control is a key ingredient for sustainable crop production. Most toxic substances produced by microbial pathogens have been identified as peptides, but they are very different in terms of structure, toxicity and specificity. Therefore, the objective of the present investigation was to determine the bioefficacy of the entomopathogenic fungus, 12 Metarhizium anisopliae (Metchnikoff) Sorokin, isolates against 2nd instar larvae of the tomato fruit borer Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) under in vitro conditions. In vitro studies an bioefficacy of 12 Metarhizium anisopliae (Metschnikoff) (Sorokin) isolates (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11 and M12) at four different concentrations of 1x1010, 1x109, 1x108, 1x107 against 2nd instar Helicoverpa armigera (Hubner) larvae revealed that all the strains were pathogenic to the target pest at all spore concentrations. However, among them isolates M3 and M7, were most effective and recorded 95 and 85% larval mortality with LT50 value of 47.82 and 56.75 hours at the lowest spore concentration (1x1010 spores ml-1) and LC50 values of 5.06x105 and 2.29x107 spore ml−1, respectively. The lowest mortality (62.50%) was recorded in isolate M4 at 5 days after inoculation. These findings suggested that the adverse effect of most virulent M. anisopliae isolates M3 and M7 were compatible and most virulent to the target pest and that the simultaneous use may be helpful for managing H. armigera, 2nd instar larvae.

Role of Potash nutrient in the management of Cassava Mosaic Virus Disease caused by Cassava Infecting Geminiviruses (CIGs)

Paper ID- AMA-07-12-2022-11869

Cassava (Manihot esculenta Crantz.) is one of the major tuber crops in tropical and sub-tropical Africa, Asia and Latin America where it is the basic staple crop for 500 million people. The major constraint in cassava production in India and Africa is Cassava mosaic disease (CMD) caused by Cassava infecting geminiviruses (CIGs) belonging to the family of Geminiviridae and Genus Begomovirus which is transmitted by whitefly Bemisia tabaci Genn. A study was carried out to manage the Cassava Mosaic Disease with graded doses of potash nutrient. In this study, least disease incidence (34.33 per cent), least disease severity (1.21), least concentration of Cassava mosaic virus (0.450), maximum plant height of 117.56 cm and maximum cassava tuber yield of 43.00 t/ ha were recorded in the cassava plants applied with 45:90:320 kg of NPK / ha as basal dose and 45:320 kg of NK / ha during split application at 90 DAP as against control (45:90:0 kg of NPK / ha as basal dose and 45:0 kg of NK / ha during split application at 90 DAP) [95 per cent, 4.53,1.947, 58.94 and 20.35t/ha respectively).

Probiotics are the live microbial food supplements which improves the microbial balance and enhanced rapid cellular growth and development. Commercial probiotics viz., Lactobacillus rhamnosus, Saccharomyces boulardii and Bifidobacterium longum with six different concentrations (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 %) were used to fortify the mulberry leaves, fed to silkworm and studied its impact on gut population, enzymatic activity and economic parameters. Among the different concentrations, 3 % recorded maximum bacterial population, amylase activity and improved economic parameters in all the probiotics treated CSR 2 larvae. Among the three probiotics, Bifidobacterium longum @ 3 % recorded highest gut population of 3.11 x 107 cfu/ml and 3.56 x 107 cfu/ml in fourth and fifth instar larvae. amylase activity (64.79 mg/g) and economic parameters like cocoon weight (1.52 g), Pupal weight (1.20g), shell weight (0.32 g) cocoon weight and shell ratio (21.05 %) respectively. The present findings of the study strongly suggested that fortification of probiotics to silkworm through mulberry feed enhances gut microbes, enzyme activity thereby economic parameters of silkworm.
