Nutrient Management Techniques for Organically Grown Finger Millet

Madras Agricultural Journal (2020)

E. Somasundaram K. Ganesan R. Ganesh R. Sunitha Udhaya Nandhini D

Field experiments were conducted at TNAU, Coimbatore during 2019 and2020 for developing organic nutrient package for finger millet (Ragi) usingthe variety CO (Ra) 15. Treatments included twelve combinations of weedcompost, enriched vermicompost, enriched farmyard manure (EFYM) as soilapplication along with panchagavya, effective microbes (EM), vermiwash, eggamino acid as foliar spray. The experiment was laid out in RBD with threereplications. The results showed that application of enriched vermicompost@ 1t ha-1 applied in two equal splits on 25 and 40 DAT along with foliarapplication of egg amino acid @ 5% on 30 and 45 DAT was found to be thebest nutrient management package for organic finger millet based on thegrain yield (2746 kg ha-1). However the maximum net return (Rs. 31,477)and BCR of 1.94 was recorded under basal application of EFYM @ 750 kgha-1 along with foliar spraying of EM @ 5% on 30 and 45 DAT thus proving asan economically viable nutrient package for organic finger millet production.

Developing an Economically Viable Nutrient Management Package that Sustains Growth, Yield and Quality of Chilli (Capsicum annuum L.)

Madras Agricultural Journal (2023)

R. Sunitha R. Ganesh M Suganthy S Manickam

The field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during 2021 to develop an economically viable nutrient management package for chilli that sustains growth, yield and quality of the produce at the same time. The experiment was laid out in randomized block design with six treatments and five replications. The treatments consisted of organic, inorganic and combined nutrient management practices. The results revealed that the state recommended practices (Farm yard manure @ 25 t ha-1 + Azophos @ 2 kg ha-1 + recommended dose fertilizers (RDF)) registered the highest plant height (71.7), number of branches per plant (24.7), leaf area (22.5 cm2), number of fruits per plant (79.4) and yield per hectare (16589 kg). However, interms of economics the organic nutrient management practices performed well with 50 % N requirement through organic manures (50 % FYM + 50 % Vermicompost) + seedling treatment with Beejamrit + Ghanajeevamrit @ 250 kg ha-1, Jeevamrit @ 500 litres ha-1 time-1 twice a month with irrigation water fetching higher benefit cost ratio (2.40). The quality parameters like total soluble solids (TSS) and ascorbic acid content were also higher (5.84 °brix and 127.46 mg 100 g-1 respectively) under 50 % N requirement through organic manures (50 % FYM + 50 % Vermicompost) + seedling treatment with Beejamrit + Ghanajeevamrit @ 250 kg ha-1, Jeevamrit @ 500 litres ha-1 time-1 twice a month with irrigation water applied plots compared to other nutrient management practices. It can be concluded that the application of state recommended management practices had a positive effect on growth and yield. However for getting economically sustainable and quality chilli, the organic package – 50 % N requirement through organic manures (50 % FYM + 50 % Vermicompost) + seedling treatment with Beejamrit + application of Ghanajeevamrit @ 250 kg ha-1, Jeevamrit @ 500 litres ha-1 time-1 twice a month with irrigation water can be suggested.

Evaluation of Traditional Varieties of Rice (Oryza sativa L.) for Yield under Organic Production System

Indian Journal of Agricultural Research (2022)

Sivakumar Manickam M. Suganthy R. Sunitha R. Jansirani R. Krishnan

Background: Organic farming seems to be one of the best options to offer healthier food and environment in the present situation. However, non availability of promising varieties is a major constraint which inevitably makes us to shift towards traditional varieties. Rice being the major crop grown and consumed in Tamil Nadu, an attempt was made to study the yield potential of different traditional varieties of rice under organic cultivation. Methods: The experiment was conducted during rabi season of 2020-2021 at wetland farms of Tamil Nadu Agricultural University, Coimbatore. The experiment was laid out in RBD with twelve varieties replicated thrice under SRI method. The treatments consisted of twelve traditional varieties viz., Athur Kichili samba, Garudan samba, Illuppaipoo samba, Milagu samba, Poonkar, Sorna masuri, Thooya malli samba, Thanga samba, Kuzhiadichan, Kullakar, Anaikomban and Thulasi vasa samba. Result: The investigation revealed that significantly higher plant height, number of productive tillers, panicle weight, panicle length, fertility percentage were observed in Kuzhiadichan and Anaikomban which eventually led to higher grain and straw yield. The aforementioned varieties have also fetched higher net returns of Rs. 96,476 ha-1 and Rs. 73,893 ha-1, respectively indicating their suitability under organic production system.

Performance Estimation of Self-Circulating Fluidized Bed Gasification with mixtures of Biomass

Journal of Physics Conference Series (2024)

M. Selvaraj R. Jaganraj R. Ganesh N. Srinivasa Rao A. Pradeep

Abstract The thermochemical conversion method is a well-proven technology for producing synthesis gas. Mixture of biomass in varied ratios is a novel strategy that has been tested in Self-Circulating Fluidized Bed gasification (SFBG). SFBG is designed and tested using the aforesaid biomass at a mixture ratio of 75%-25% for equivalency ratios of 0.3, 0.4, and 0.5. The gasification system’s overall effectiveness was assessed by considering crucial factors, including gas production, the heating value of the generated gas, carbon conversion, and the efficiency of the system in producing cold gas.

A Step into Future Fuel Industrial Effluents into Bioethanol: A Review

International Journal of Environment and Climate Change (2023)

R. Ganesh R. Parimala Devi Desikan Ramesh Subburamu Karthikeyan D. Murugananthi

Industrial revolution in agro based industries with improved technologies, machineries, etc. has resulted in the ease of operation, availability of increased number of value added products in the field of agriculture, effective labour management, etc. Agro industries are one of the major contributors for environmental pollution and accounts for about 10-15% for pollution. As the wastes generated from agro-industries are of biological origin, they can be effectively reused; if their alternate uses are explored. As these industrial effluents contain lignocellulose, cellulose, and hemicellulose, which are rich sources of lignin, and cellulose, it is possible to use these materials as a substrate to produce bioethanol. Our current review focuses on bioethanol production from different industrial effluents and Bio-microbial based fermentation.

Constrains in Biofertilizer Development and Environmental Factors Influencing its Survival in Soil: A Review

Agricultural Reviews (2022)

R. Ganesh Maneesh Kumar J Kavipriya R. Krishnamoorthy

Bio-inoculants (Biofertilizer) are an agricultural input that helps to keep the environment clean. By definition biofertilizers are efficient strains of isolated microorganisms that help plants grow in a variety of ways, both directly and indirectly. Biological nitrogen fixation, phosphate solubilization, phosphate mobilisation, siderophore generation and phytohormone production are some of the direct methods. The majority of efficient bio-inoculants perform better in laboratory conditions but fail to achieve the same results in the field. Due to the poor performance of bio-inoculants in field conditions, biofertilizers are not widely accepted by the farming community. Soil pH, temperature and chemical residues are considered as important abiotic stress. The key soil biotic elements are native microflora, predatory organisms and virus. Some bacteria are able to live despite the stress, but the total efficacy of the applied biofertilizer is diminished. Bio-inoculants must resist a variety of biotic and abiotic stresses in the soil, depending on the circumstances. We look at the obstacles that bio-inoculants confront in terms of survival and performance in the field.
