The productivity of groundnut farming is currently declining due to pest and disease attacks, use of old and traditional low-yielding varieties. To tackle the issues demonstrations on cluster mode are essential. Cluster Frontline Demonstration (CFLD) is conducted by Subject Matter Specialists (SMSs) and scientists in a systemic manner on selected farmers field to spread the new variety and groundnut production technologies. The ICAR- KVK, Tindivanam had organized CFLDs on groundnut crop in two villages viz., Nolambur and Kilmavilangai. Therefore, the study aimed to know the profile characteristics of CFLD beneficiary farmers and to encounter the major constraints faced by groundnut growers. To get an adequate sample size, 60 CFLD beneficiaries were selected randomly for the present study. The data were collected by using a pre-tested interview schedule. Garrett’s ranking technique and percentage analysis were used to analyze the data for meaning interpretation. The majority of beneficiaries belonged to middle age category (61.66%), majority of male beneficiaries (80.00%), educated upto middle school (40.00%), land holdings of 1 to 2 ha (68.33%) as small land, 20- 30 years of farming experience in oilseeds (80.00%), participated in one training (66.67%), medium level of extension agency contact (66.67%) and mass media exposure (56.67%), 55 per cent of farmers were adopted new practices after the successful adoption of other members. The major constraints include poor labour availability, poor transport facilities, lack of proper marketing channels and lack of technical knowledge. Hence, CFLD showed that medium to high level profile characteristics and improved adoption of new technologies.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135688558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its ability to grow on soil of low organic content and produce high yield, it is considered a food security crop in African countries. Now it became the industrial crop since it is raw material for the production of starch, energy and live stock feed. In Tamil Nadu, it is grown in Salem, Namakkal, Erode, Cuddalore, Dharmapuri and Kanyakumari districts, both in irrigated and rainfed condition. Recently , the major constraint in cassava production are mealybug damage. The invasive mealybug species, Phenococcus manihoti Matile-Ferrero (Pseudococcidae) was first reported from Salem district and its occurrence was found associated with other species of mealybug. The nymphs and adult of mealybugs were collected from farmer”s field in Namakkal, Salem and Tiruppur district and morphological characters were observed to identify the key characters of mealybug species. Among the specimens collected, the species identified with colour, wax coating and body filaments were Ferrisia virgata, Pseudococcus jackbeardsleyi and P. manihoti. P. manihotidifferentiated from the other species with its distinct symptom of distortion of leaves at tip (Bunchy top) and extensive honey dew secretion.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90221647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, pigmented traditional rice varieties have become popular among the consumers due to its dark pigmented pericarp having nutritional value. This type of rice variety is important in determining the digestibility of starch and its Glycemic index (GI). The digestibility of the rice depends on the properties of starch, including its crystallinity and amylose: amylopectin ratio. Hence, the study focuses on the analysis of phyto nutrients in the selected traditional and TNAU released rice varieties to identify the low GI lines. Nutritional analysis of the selected traditional rice genotypes namely Karuppu kavuni, Karun kuruvai (black), Kaattuyanam, Mapillai samba and Kuruvai kalanchiyam and five ruling TNAU released rice varieties (ADT 52, TKM 9,TKM 13, ASD 16 and CO51) has been carried out. Among the selected traditional and TNAU - released rice varieties, Mapillai samba showed the strongest alpha-amylase inhibition (IC50 = 23.15 μg/mL), maximum anthocyanin content (48.37 mg/100g), and phenolic content (45.8 mg/100g), highest total antioxidant activity (51.8% DPPH scavenging activity.

An impact study seeks to understand how well a program or course, achieves its intended objectives and how it affects the participants, the institution, and the broader community. Sericulture, the art, and science of making silk, has played a significant role in human culture for many years as a source of luxury, wealth, and employment in rural areas. In response to this demand, Tamil Nadu Agricultural University is offering Sericulture certificate programmes in distance mode. It has arisen as a potential way to educate and enable people from every aspect of life, particularly those living in rural regions, to engage in this lucrative industry. Sericulture course was chosen among 41 certificate courses and responses were collected from the successfully completed learners. This paper attempts to explain the impact of the course concerning eight various dimensions that describes the level of impact attained by Sericulture certificate course among learners. As, the study investigates the impact obtained by past learners, the research design Ex post facto design was utilized to conduct the study. The sample for the study was successful learners who had completed their certificate course during the year of 2019 (55) and 2020 (32) as total 87 successful learners were taken for the study from various districts in Tamil Nadu. Chi square test revealed that there is significant association between Geographical distance (0.016), Job aspiration (0.057*), Experience in Sericulture (0.009), Attitude towards Entrepreneurship (0.007) and Motivation (0.056*) with Impact of Sericulture certificate course.

Crop management input in the model was based on the recommended practices of UAS, Dharwad, across four dates of sowing from 1st October to 15th October at quarterly intervals on black clay soil. The simulated outputs were analyzed at decadal interval for both past (1991-2020) and projected climate (2021-2050). Under past climate, two irrigation was simulated i.e., one irrigation at 40-45 days after sowing (DAS) and another at pod filling stage (70 DAS). The number of irrigations decreased by one under projected climate i.e., only one irrigation at 45 DAS. Yield reduction in rainfed conditions on black clay soil under past climate was 31.6 %, which in contrast, decreased by 16.4 % under projected climate and is presented against spatial distribution across NIK. Sowing early i.e., on 01st October under projected climate (2021-2050) simulated the lowest yield reduction (rainfed) and require fewest irrigations across 12 districts of NIK.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90354841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
