Therefore, the present experiment was conducted during the special season of 2020-2021 at Sugarcane Research Station, Cuddalore, Tamil Nadu this experiment was conducted to study the influence of combining different mediums like Cocopith, Vermicompost, Pressmud, Farm Yard Manure (FYM) on seedling vigour of sugarcane under Sustainable Sugarcane Initiative (SSI). The experiment was laid out in CRD replicated thrice with 8 treatments using CoC 13339 as test variety. The treatments consisted of combinations different combinations of cocopeat, vermicompost, compost pressmud and farmyard manure along with growth regulators. The germination percentage, root shoot ratio, seedling vigour and chlorophyll content were observed. It was concluded that pre-plant treatment of sugarcane bud chips with plant growth promoters NAA 1mM and CaCl2 1mM and 75% coirpith along with 25% vermicompost improved sprouting percentage and seedling establishment. Hence, it improved the performance of novel bud chip technology for producing vigorous seedlings.

Optimization of wholesome composite cereal and fruit-based smoothie employing Response Surface Methodology

Paper ID- AMA-09-12-2022-11876

Smoothies are characterized as beverages having better nutritional and functional properties due to inclusion of variety of ingredients. These can be further categorized as dairy and non-dairy, on the basis of choice of ingredients utilized. In the present study, the milk-based smoothie fortified with vital cereal (constituting oats, chia seeds) and fruits-based ingredients (antioxidant-rich fruit-the blueberries) was developed. To start with, various preliminary trials were conducted to select the range for major ingredients which has major influence on the sensory parameters of the beverage. However, to further narrow down these ranges and visualizing minor effect of these entities on sensory & physico-chemical properties, modern mathematical optimization tool of response surface methodology (RSM) was utilized. To bring out a uniform composition, concentration of chia seeds, and milk composition was remained constant. The estimation of a comprehensive quadratic model with interaction effects was made possible by using a Box-Behnken experimental design with three levels on the three most important parameters. It was observed that the concentration of all parameters (oats, honey and blueberries) had significant effect on the sensory attributes (P≤0.05). The optimization exercise brought a composition of 1.5, 6.5 and 6.0 percent oats, honey & blueberries with maximum desirability of 0.923, approaching to 1. Examined models effectively demonstrated the significant influence on different process parameters indicating significant regression of coefficients (R2>85%). Non-significant results difference between predicted and observed values validated the authenticity of optimization applied.

Productivity of Groundnut Influenced by Heat Units (Growing Degree Days)

Paper ID- AMA-09-12-2022-11875

Meteorological indices viz. growing degree days (GDD), helio thermal unit (HTU), and photo-thermal unit (PTU) based on air temperature are used to describe changes in phenological behavior and growth parameters. Plants have a definite heat requirement before they attain certain phenophases. A change in temperature during phenophases of a crop adversely affects the initiation and duration of different phenophases and finally the economic yield. Among the different management factors, sowing time plays a key role in obtaining higher yield. The objective of this study was undertaken to find out the optimum sowing window and the amount of heat units required to change their phonological development for groundnut variety VRI 2. A field experiment was conducted at experimental farm of Agricultural College and Research Institute, Eachangkottai during Margazhi pattam 2019 and 2020. The experiment was conducted in Randomized Block Design with four replication. Different morphological indices were observed like plant height, number of branches, dry matter and number of pods and yield attributes and yield of groundnut VRI-2 was recorded. The heat unit concept of Growing Degree Days also worked out for individual sowing windows. Among the sowing dates, Fifth January, recorded essential GDD of 1651.3°C and higher growth attributes, yield attributes and yield of groundnut (2370 kg ha-1).

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.
