Sugarcane is cultivated in an area of 4.5 million ha with an average productivity of 79 t/ha. Sustainable Sugarcane Initiative (SSI) is one of the advanced methods of sugarcane cultivation technique that involves, use of less input like seed sett, water, land, labour and optimum utilization of fertilizers to achieve maximum yield. Removal of mother shoot is one of the main techniques of SSI to get even number of tillers, increase the number of tillers and millable canes per plant. Conventional tool like secateurs, knifes and sickles being used among the sugarcane growers, even after experiencing the less efficiency of tool. In addition, more drudgery is involved, because the agricultural labourers need to bend down and hold the stem to remove the mother shoots in each sugarcane plant. Chances of getting injury to the hands and eyes are more during this operation. Hence, a hand operated tool for removing the mother shoot of sugarcane plants was developed and evaluated in sugarcane crop during 30 to 35 days after transplanting. The tool is manual operated and can be operated in standing posture for a long time. Women labourers can also cuts sugarcane mother shoots easily due to low weight (1.6 kg) of the tool. The tool saves cost and time by 47 per cent and 44 per cent, respectively compared to cutting of mother shoots with sickle. One could cut 1200 shoots/h with the tool. The tool costs Rs. 800/- and cost of operation is Rs.465 per hectare","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"212 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76157273","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}

An experiment has been conducted in 2021 at Western block farm, Horticultural College and Research Institute, Periyakulam under irrigated conditions to study the effect of crop geometries and harvesting heights on leaf yield of moringa var. PKM 1. Treatments combination consists of four crop geometries viz., 1.50m x 0.25m (S1), 1.50m x 0.50m (S2), 1.50m x 0.25m x 0.25m (S3), 1.50m x 0.50m x 0.50m (S4) and three harvesting heights of 30 cm (T1), 45 cm (T2) and 60 cm (T3). The study laid out in a Split plot design with three replications. The growth parameters such as plant height and a number of compound leaves were significantly higher in the closer spacing of 1.50m x 0.25m x 0.25m whereas a number of primary branches and stem girth were significantly higher in the wider spacing of 1.50 m x 0.50 m. Harvesting heights have no influence on the growth parameters. Moringa raised under spacing 1.50 m x 0.25 m x 0.25 m in conjunction with harvesting height of 30 cm (S3T1) significantly influenced the yield parameters such as compound leaf yield, fresh leaflets weight, dry leaf weight, and found maximum.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"832 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91461286","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}

The data of plant height, number of leaves, single leaf area, single-leaf weight, leaf mass area, leaf area index (LAI), leaf angle, yield, and biomass were subjected to analysis of variance that showed significant differences among the genotypes. The genetic variability among the genotypes and the co-efficient of variation was high for all the traits analyzed except leaf mass area with 17.47%. A high coefficient of variation was recorded in the number of leaves and grain yield per plant with 42.68 and 38.55%, respectively. Frequency distribution for these traits showed that the genotypes in the category of 4 to 12 LAI fall in the category of 30 to 90g of grain yield. Most of the traits showed symmetrical skewness and mesokurtic distribution.Besides, the correlation coefficient of LAI had a significantly positive correlation with leaf mass per area, leaf numbers, and biomass, indicating the importance of the leaf area index in determining yield and biomass. Furthermore,single leaf area hada significant positive association with leaf angle, single-leaf weight, and plant heightand a negative correlation with leaf numbers and leaf mass area.The results revealed the highest genetic variability and association between two or more variables among this rice germplasm.

There were six nutrient management practices consisting of organic, inorganic and combined sources of nutrients, which were evaluated, in randomized block design with five replications. Among the practices, the state recommended nutrient management practice (Farm yard manure (FYM) @ 25 t ha-1 + Azophos @ 2 kg ha-1 + Recommended dose of fertilizers (RDF)) performed well with respect to plant height (88.7), number of primary and secondary branches per plant (49.8), number of fruits per plant (11.6) and yield per hectare (25,794 kg). Whereas, the organic nutrient management (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) performed well with respect to gross return (Rs. 299288 ha-1), net return (Rs. 183844 ha-1) and benefit cost ratio (2.59). The quality parameters like ascorbic acid content, total soluble solids (TSS) and titrable acidity were also higher under the organic source of nutrients compared to only chemical or integrated nutrient sources. It can be concluded that the productivity of tomatoes were higher under state recommended nutrient management practice (FYM @ 25 t ha-1 + Azophos @ 2 kg ha-1 + RDF). However for getting highly profitable and quality tomato production, 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 recommended.","PeriodicalId":18154,"journal":{"name":"Madras Agricultural Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90570022","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}

Based on viable mutation frequency in M2 generation, the mutagenic effectiveness and efficiency of the mutagen were determined. The mean lethal concentration (LD50) and mean concentration for 50 per cent reduction in growth (GR50) doses were determined to be 41 mM and 45 mM, respectively based on survival per cent and shoot length reduction over control.

Social intelligence involves identifying key interaction skills and then assessing them behaviorally. Emotional intelligence and social intelligence make an important role in the academic and social life of students. This study attempted to measure the level of Emotional intelligence and Social intelligence of the postgraduate agricultural students of Tamil Nadu Agricultural University. Using a proportionate random sampling method, 138 students (52 boys & 86 girls) were considered respondents for this study. Wong and Law's emotional intelligence scale and Tromso's social intelligence scale were used to assess respondents' levels of emotional intelligence and social intelligence.
