Book chapterItem Open Access Agronomic Packages for Enhancing Cereal and Legume Fodder Production(TANUVAS, Chennai, 2014) Murugan, P.; Suganthi, M.; Kumaravel, P.In India where over 75% farmers are small and marginal holders, livestock is the main source of livelihood for a majority of the rural population.ArticleItem Open Access Economics of Feeding Hydroponic Maize Fodder in Madras Red Sheep(TANUVAS, Chennai, 2021-01) Pasupathi, Karu.; Jeichitra, V.; Suganthi, M.; Balasubramanyam, D.; TANUVASAn experiment was conducted to assess the growth performance of Madras Red sheep on hydroponic maize fodder replacing Bajra Napier grass Co(CN)-4 at 50 and 100 per cent level. Madras Red ram lambs of about 4 months of age (33 Nos.) were randomly divided into three groups. All the lambs of three groups were fed with concentrate feed @ 100 g/ day. In addition, Group-1 lambs were fed with 100 % Co(CN)-4; group-2 lambs were fed with 50 % Co(CN)-4 and 50 % hydroponic maize fodder and group – 3 lambs were fed with 100 % hydroponic maize fodder to meet out their dry matter and nutrient requirement. The trial was conducted for three months. During the trial period the data collected were initial body weight, monthly body weight, final body weight, feed intake, and cost of feeding. No significant differences were observed in the average weight gain, dry matter intake and feed conversion ratio among the treatment groups. Cost of feeding per kg live weight gain was found higher as the inclusion level of hydroponic fodder included increased in the ration. Hence, hydroponic fodder can be recommended when acute fodder deficiency occurred especially during summer.ArticleItem Open Access Effect of Different Weed Management Practices on Growth and Yield of Direct Seeded Puddled Rice in North Eastern Zones of Tamil Nadu(IJPSS, 2022-08) Suganthi, M.; Mynavathy, V.S.; Murugan, M.; Balasubramaniyam, D.; TANUVASThe field experiment was conducted at Post Graduate Research Institute in Animal sciences Kattupakkam Tamil Nadu, India during Rabi (Oct-Mar) seasons of 2016-17 to study the effect of different weed management techniques in direct seeded puddled rice variety ADT 43. The experiment was laid out with unpaired t test design. The treatment of chemical weed management technique (pre - emergence application of pretilachlor) was compared with two time manual weed management technique (control) in direct seeded puddled rice. Among the weed management techniques, chemical weed management technique significantly influenced the growth and yield characters and yield of direct seeded puddled rice. The maximum plant height, number of tillers /hill, grain yield, straw yield and cost benefit ratio were recorded under chemical weed management technique during Rabi. The lowest grain yield, straw yield were recorded under control treatment.ArticleItem Open Access Management of Soil Physical Constraints – A Review(2017-04) Suganthi, M.; Muthukrishnan, P.; Chinnusamy, C.; Subramonian, B. Suresh; TANUVASThe enhanced soil productivity and assured sustainability are the two major issues of concern in order to feed the increasing population of the world. The alleviation of soil physical constraints limiting crop production is considered important to increase agricultural production and sustaining the productivity of soils. The major soil physical constraints include high soil permeability, soil surface crusting, sub-surface mechanical impedance and soil hardening. Studies indicated that management of highly permeable soils such as by compaction increased yields of various crops. Soil surface crusting could be managed by application of FYM on seed lines at the rate of 4 t/ha. Application of tank silt has improved the physical properties of soil like reduces the bulk density and improved the water holding capacity of the soil. The objective of this paper is to present the various results of several field experiments conducted during the last two and a half decades to identify soil physical constraints limiting crop production and different options for their management.ArticleItem Open Access Phytostabilisation for Contaminant Containment – Review(2017-07) Suganthi, M.; Muthukrishnan, P.; Chinnusamy, C.; Gopi, H.; TANUVASPlants represent a more environmentally compatible and less expensive method to site restoration compared to physico-chemical approaches, even if the time scale required to reach the target end-points is often a limiting factor. Plants are already cleaning our environment constantly, everywhere, acting as “green livers”, even if we do not recognize or know it. Phytoremediation is the in situ use of plants and their associated microorganisms to decontaminate a polluted site. The processes for the phytoremediation of organic pollutants, petroleum hydrocarbons in particular, are primarily by Phytodegradation, Phytostimulation, Phytovolatilization and Phytostabilization. In phytostabilization process plants are used to stabilize the soil and the contaminant resulted in clean environment.Book chapterItem Open Access Suitability of Fodder Production in Different Type of Soils and Fodder Seed Production(TANUVAS, Chennai, 2014) Suganthi, M.; Murugan, P.; Kumaravel, P.India is basically an agricultural country. Nearly 70 percent of country’s population lives in rural areas.ArticleItem Open Access கம்பு நேப்பியர் ஒட்டுப்புல்லில் நீர்பாசன நாள் பற்றிய ஆய்வு(Naam Thamizhar Pathippagam, Chennai, 2019-02) Suganthi, M.; Elango, A.; Selvan, S.T.; TANUVASஆய்வானாது கோடைகாலத்தில் (பிப்ரவரி– ஜூன்- 2016) கால்நடை முதுகலை அறிவியல ஆராய்ச்சி நிலையம் காட்டுப்பாக்கத்தில், நீர்பாசன வசதியுள்ள நிலத்தில் மேற்கொள்ளப்பட்டது. நிலமானது செம்மண் கலந்த களிமண் பூமியாகும். மேலும் மண்ணானது நடுநிலை கார அமிலதன்மை (PH-7.6) குறைவான தழைச்சத்து (90 கிலோ/ஏக்கர்) அதிக மணிச்சத்து (15.2கிலோ/ஏக்கர்) மற்றும் நடுநிலை சாம்பல் சத்து (57.2 கிலோ/ஏக்கர்) ஆகியவற்றைக் கொண்டது. ஆய்வின் முடிவில் நான்கு நாட்களுக்கு ஒருமுறை நீர்பாய்ச்சுதல் மற்றும் ஆறு நாட்களுக்கு ஒருமுறை நீர்பாய்ச்சுதல் ஆகியன அதிக விளைச்சலைக் கொடுத்தது. மேற்கண்ட இரு ஆய்வுக் கூறுகளும் ஒன்றுடன் ஒன்று ஒப்பிடும்படியாகவும் இருந்தது.ArticleItem Open Access வேறுபட்ட பருவக்காலத்தில் கலப்பினக் கறவை மாடுகளின் ஆரோக்கிய மற்றும் நஞ்சுக்கொடி தேக்கத்தில் தாது உப்புக்களின் அளவு(Veelan ariviyal tamil iyakkam, Newdelhi, 2016) Usha, S.; Muthusamy, N.; Suganthi, M.
