Intelligence is a general mental capability that involves the ability to reason, plan, think abstractly, comprehend ideas, language, and learn things. Being excellent in general intelligence (IQ) alone will not guarantee success in a student's life. Emotional intelligence is an important element in enhancing an individual's ability and skills in communication and interpersonal relations. 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. Findings of this study revealed that more than sixty percent (67%) of the respondents had a medium level of emotional intelligence and sixty-seven percent of respondents were under the moderately socialized category.
智力是一种一般的心理能力,包括推理、计划、抽象思考、理解思想、语言和学习事物的能力。仅仅拥有优秀的综合智力(IQ)并不能保证学生一生的成功。情商是提高个人沟通和人际关系能力和技能的重要因素。社交智力包括识别关键的互动技能,然后对其进行行为评估。情商和社会智力在学生的学业和社会生活中发挥着重要作用。本研究试图测量泰米尔纳德邦农业大学农业研究生的情绪智力和社会智力水平。采用比例随机抽样的方法,138名学生(52名男生和86名女生)被认为是本研究的受访者。采用Wong and Law的情绪智力量表和Tromso的社会智力量表来评估被调查者的情绪智力和社会智力水平。本研究结果显示,超过60%(67%)的受访者具有中等水平的情绪智力,67%的受访者属于中度社交类别。

The biochemical factors can provide a source of resistance and chemical stimuli play a vital role in host plant selection by feeding and oviposition. The development of genotypes/varieties resistant to melon fruit fly is an essential component of Integrated Pest Management. Field experiments were conducted during 2018-19 in farmer’s field at Ellamanam village and laboratory studies were conducted at the Department of Plant Protection, Anbil Dharmalingam Agricultural College and Research Institute, Tamil Nadu Agricultural University, Tiruchirappalli District. A screening of 12 accessions/varieties (2 resistant, 6 moderately resistant, 3 susceptible, and 1 highly susceptible) was selected for y- tube olfactometer studies to confirm resistance. The behavioral response of fruit fly, Z. cucurbitae, to kairomone compound emitted from bitter gourd leaves and fruits were extracted using different solvents viz., hexane, dichloromethane, and distilled water. The result concluded that hexane and dichloromethane leaf and fruit extract of TCR 393 showed high duration for fruit fly attraction and lower attractancy, followed by Musiri local-1, MC-10, Ucha small, Bikner -2 , Musiri local-2, and CO-1 and if identified kairomone compound may be useful for monitoring and managing of Z. cucurbitae.

Mutation breeding is an important approach to crop improvement. Identifying beneficial mutagen and its optimum dose are the prerequisites for any successful mutation breeding program. The present study aimed to identify the optimum dose, mutagenic effectiveness, and efficiency of various concentrations of EMS mutagen in proso millet variety ATL 1. Ten treatment concentrations 10 to 100 mM and control were evaluated using germination paper, tray, and field method to estimate the effect of the mutagen on seedling growth and survival in M1 generation. 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. The mutagenic effectiveness was the highest at 50 mM and mutagenic efficiency was the highest at 40 mM. Broad-spectrum of viable mutants was identified in M2 generation that could be utilized to develop improved cultivars in the crop.

The food retail industry is represented as a sunrise industry in the world because of its large potential for growth and socio-economic impact. Because of the critical linkages and synergies, it fosters between the two pillars of our economy, industry, and agriculture, the food retail industry is extremely important to India’s development. Britannia Industries Limited, Heritage Foods Limited, Kwality Industries Limited, KRBL Industries Limited, ITC Limited, and PepsiCo India Holdings Pvt. Ltd was chosen for the study based on financial ratio analysis. From 2015 to 2019, the research was conducted across five years. Britannia Industries Limited, KRBL, and Kwality Industries’ current ratios are 1.94, 1.86, and 1.51, respectively, approaching 2:1. It shows that all three companies have sufficient current assets to cover their current liabilities. ITC’s current ratio is 3.64, indicating that the company is more liquid, which could affect profitability in the long run. The quick ratios of Kwality Industries and Britannia Industries are both good at 1.08 and 0.61, respectively. These two companies have adequate liquidity to meet their short-term obligations. ITC, Britannia, and PepsiCo have debt-to-equity ratios of 0.002,0.07, and 0.02, correspondingly. It implies that their primary source of funding is from their own money rather than loan capital, which causes an increase in the cost of capital and, in turn, affects their profitability in the long run.

A field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore during 2020 to evaluate the efficacy of various sources of nutrients on the growth, quality, yield and economics of tomato (Solanum lycopersicum L). 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.
本试验于2020年在哥印拜陀泰米尔纳德邦农业大学(Tamil Nadu agriculture University)开展,采用随机区组设计(5个重复),采用有机、无机和复合营养源6种养分管理方式,评价不同营养源对番茄生长、品质、产量和经济效益的影响。在这些做法中,国家推荐的养分管理做法(农家肥(FYM) @ 25 t ha-1 +偶氮磷@ 2 kg ha-1 +肥料推荐剂量(RDF))在株高(88.7)、每株一次枝数(49.8)、每株果数(11.6)和每公顷产量(25,794 kg)方面表现良好。然而,有机养分管理(通过有机肥料(50% FYM + 50%蚯蚓堆肥)满足50%氮需求+ bejamrit + Ghanajeevamrit @ 250 kg ha-1, Jeevamrit @ 500升ha-1次-1,每月两次,灌溉水)在总收益(299288 ha-1),净收益(183844 ha-1)和效益成本比(2.59)方面表现良好。有机营养源的抗坏血酸含量、总可溶性固形物(TSS)和可滴定酸度等品质参数也高于单纯化学或综合营养源。结果表明,在国家推荐的营养管理措施(FYM @ 25 t ha-1 +偶氮磷@ 2 kg ha-1 + RDF)下,番茄产量较高。然而,为了获得高利润和优质的番茄生产,建议采用有机包装-通过有机肥料(50% FYM + 50%蚯蚓堆肥)要求50%的氮+ Beejamrit苗木处理+ Ghanajeevamrit @ 250 kg hm -1, Jeevamrit @ 500升hm -1,每月两次,并使用灌溉水。

The present study was conducted to assess the gene interaction for grain yield and its attributing traits towards the increase of grain yield in sorghum. In F3 generation, symmetrical distribution, positive skewness and negative skewness were observed for 14 traits in various crosses. Symmetrical distribution indicates the presence of segregating genes that gives wider variation in F3 populations. Significant and positive skewness indicates the complementary type of gene action hence the expected genetic gain is slower with mild selection and faster with intensive selection for that particular trait. Significant and negative skewness denotes the presence of duplicate epistatic gene action therefore the gain is faster with mild selection and less rapid with intense selection. In kurtosis, leptokurtic and mesokurtic nature was observed which indicate that the traits are under the control of few segregating genes and the next indicates the nonsignificant of kurtosis respectively. The intensive selection of these characters in F3 generation paved the way to achieve the gain faster

An experiment was conducted to document the population dynamics of wood-boring bostrychid beetles collected from different wood yards at Mettupalayam, Tamil Nadu. The abundance of wood boring beetles showed that out of 455 individual beetles collected from different wood pieces, 319 beetles belonged to the family bostrychidae. Sinoxylon sp. (Coleoptera: Bostrychidae) was the dominant species accounting 76.70 percent. Diversity indices were calculated for the wood-boring beetles recorded as Shannon Diversity Index (H) (1.34), Species richness (Margalef) (0.43), Species Diversity (D) (3.67) and Pielou’s Species Eveness (0.97). The number of exit holes were evaluated, which showed that the wood samples from sites 3, 4 and 5 had significantly higher number of exit holes than those recorded at sites 1 and 2. The size of exit holes bored by beetles showed that the wood samples of teak, silver oak, neem and eucalyptus have the maximum number of exit holes with 1.1-2.0 mm

The present investigation was carried out with five segregating populations in sorghum to assess the association between grain yield and its correlated traits. In correlation coefficients, three crosses viz., Cross 1, Cross 3 and Cross 5 showed significant positive association of grain yield with flag leaf length, flag leaf width, harvest index, plant height, number of leaves per plant, leaf chlorophyll index, stem girth, test weight (Cross 5), panicle weight, panicle length (except Cross 1) and biological yield and inter association of such traits were almost positive. Hence these three crosses could be exploited simultaneously for grain yield and other correlated traits by selection. From path coefficient analysis, it is concluded that the biological yield and harvest index had high positive direct effect on single plant yield in all crosses evaluated in the study. They also exhibited high indirect contribution on yield through yield components traits that could be used as yield determinants for further improvement in the population.

A pot culture experiment was conducted at the Department of Agronomy, Madras Veterinary College, Chennai, during rabi season 2019 - 2020 to study the influence of organic manures and synthetic fertilizers on the nutrient uptake and green fodder yield of fodder maize (Zea mays L.). An experiment was laid out with two factors and three replications. Four organic manure treatments in main-plots viz., no manure, farm yard manure (25 t ha-1), vermicompost (12 t ha-1) and poultry manure (12 t ha-1) and four fertilizer treatments in subplots viz., No fertilizer, 125% RDF, 100% RDF, 75% RDF. The recommended dose of fertilizer (RDF) for fodder maize is 60 kg N ha-1: 40 kg P2O5 ha-1: 20 kg K2O ha-1. The organic manures were applied as per the N equivalent basis to the inorganic nutrient recommendation. The results revealed that the application of nutrients through poultry manure @ 12 t ha-1 resulted in higher plant uptake of Nitrogen (112.2 kg ha-1), phosphorus ( 19.26 kg ha-1), and potassium ( 117.7 kg ha-1) followed by the application of farm yard manure @ 25 t ha-1 on N equivalent basis. Concerning fertilizers, the application of 75% recommended dose of inorganic fertilizer resulted in higher plant nitrogen, phosphorous, and potassium uptake (104.9, 18.9, 108.54 Kg ha-1 N, P, K, respectively). About the fodder yield, the highest green and dry fodder yield were recorded under the treatment combination of poultry manure along with 75% RDF 31.84 t ha-1 and 5.19 t ha-1 at 60 DAS, respectively).
2019 - 2020年rabi季,在金奈马德拉斯兽医学院农学系进行盆栽试验,研究有机肥料和合成肥料对饲料玉米(Zea mays L.)养分吸收和青饲料产量的影响。设计了一个有两个因素和三个重复的实验。主小区采用4种有机肥处理,即不施有机肥、农家肥(25 t hm -1)、蚯蚓堆肥(12 t hm -1)和禽粪(12 t hm -1);子小区采用4种有机肥处理,即不施有机肥、125% RDF、100% RDF、75% RDF。饲用玉米的推荐肥料用量为60 kg N hm -1: 40 kg P2O5 hm -1: 20 kg K2O hm -1。有机肥料按氮当量基础施用于无机养分推荐量。结果表明:在N当量基础上,施用12 t ha-1的家禽粪比施用25 t ha-1的鸡场粪肥对氮(112.2 kg ha-1)、磷(19.26 kg ha-1)和钾(117.7 kg ha-1)的吸收量更高;在肥料方面,施用75%推荐用量的无机肥提高了植株对氮、磷、钾的吸收量(N、P、K分别为104.9、18.9、108.54 Kg hm -1)。在饲料产量方面,禽粪加75% RDF (60 DAS时分别为31.84 t ha-1和5.19 t ha-1)组合处理的绿料和干料产量最高。

An experiment was laid out with two factors and three replications. Four organic manure treatments in main-plots viz., no manure, farm yard manure (25 t ha-1), vermicompost (12 t ha-1) and poultry manure (12 t ha-1) and four fertilizer treatments in subplots viz., No fertilizer, 125% RDF, 100% RDF, 75% RDF. The recommended dose of fertilizer (RDF) for fodder maize is 60 kg N ha-1: 40 kg P2O5 ha-1: 20 kg K2O ha-1. The organic manures were applied as per the N equivalent basis to the inorganic nutrient recommendation. The results revealed that the application of nutrients through poultry manure @ 12 t ha-1 resulted in higher plant uptake of Nitrogen (112.2 kg ha-1), phosphorus ( 19.26 kg ha-1), and potassium ( 117.7 kg ha-1) followed by the application of farm yard manure @ 25 t ha-1 on N equivalent basis.

In this study, 36 tomato accessions were subjected to variability and correlation analysis based on seventeen yield and quality traits. The traits viz., plant height, number of clusters plant-1 , number of fruits plant-1 , ascorbic acid content and single fruit weight were exhibited a high level of variability, heritability and genetic advance as per cent of mean and these traits are positive and significantly associated with yield, which is clearly indicates that these traits are highly responsive and simple selection is very appropriate. Per cent fruit set negatively associated with earliness and its exhibited moderate level of variability shows the presence of non-additive gene action. Lycopene and β-carotene were not substantially linked with any of the traits but these are highly heritable in nature, to incorporate these two traits into any breeding programme, the parents must be excellent in these particular quality parameters.
