Aim: To know the adaptation strategies undertaken by the respondents to deal with climate-smart agriculture.

Study Design: An expost facto research design was employed to analyse the level of adoption by the rice farmers.

Place and Duration of Study: The study was conducted during 2018-19 in Dharwad district of Karnataka state. From Dharwad district two villages namely Mummigatti from Dharwad taluk and Jodalli from Kalaghatagi taluk were selected.

Methodology: A total of 60 respondents were randomly selected and personally interviewed.

To elicit the required information from the respondents, a structured interview schedule was prepared. Through informal discussions and interviews, data was collected from the respondents. The collected data was analysed with the help of suitable statistical tools like frequency, percentage, mean, standard deviation and t-test.

Results: The results of the study revealed that majority of the respondents from Mummigatti (86.67%) and Jodalli (66.70%) had medium level of awareness regarding climate-smart agriculture. Majority of the respondents from Mummigatti (80.00%) and Jodalli (73.30%) were found in medium adaptation category. Equal percentage (20.00% each) of the respondents from both the villages belonged to the high adaptation category. The study also reveals that cent percent of the respondents from both the villages were faced constraints likelack of knowledge about adaptive practices, lack of awareness about climate change issues, non-availability of inputs in time, lack of financial resource, poor support of local and national authorities with the climate-related issue and higher cost of the agricultural inputs to cope with climatic variability.

Conclusion: From the study, it can be concluded that providing information and local support from the authorities will be of immense use in the proper adaption of site-specific climate-smart practices. The study also suggests that suitable policies and strategies should be taken to deal with non adaptation of climate-smart practices in the villages.

An investigation was undertaken to identify sugarcane clones suitable for the identification of early maturing genotypes for higher sugar yield at Research Farm of DRPCAU, Pusa, Samastipur, Bihar in Randomized Block Design with three replications during spring season 2018-19. Variability, correlation, and path analysis in twelve early maturing clones of sugarcane for twenty-one different morphological and juice quality characters were studied in relation to the checks viz. CoLk94184 and CoSe95422. Analysis of variance revealed highly significant differences for all characters studied. Genotypic and phenotypic coefficient of variation was highest for Sugar yield (CCS) at harvest (t/ha) among the early maturing clones. The highest heritability was obtained for Brix at 8-month stage, Pol in juice at 8-month stage and Brix at 10-month stage. Genetic advance as per cent of mean was found to be highest in sugar yield (CCS) at harvest, cane yield and single cane weight indicating effectiveness of selection due to preponderance of additive gene action and breeder may consider these traits as main selection criteria.

DOI: 10.9734/cjast/2020/v39i2630899

Background: Since the confirmation of the index case of Covid-19 on the 27th of February in Nigeria, the spread from Lagos to other parts of the country has been on the climb without a plateau in sight.

Objective: To characterize and present epidemiological trends of Covid-19 pandemic in the first three months of index confirmation in Nigeria.

Methods: A descriptive epidemiological study involving a review of the first three-month Covid-19 situation reports and updates in Nigeria using primary data was analyzed by Spatio-temporal analysis with categorical variables reported in percentages and numbers.

Findings: Retrospective analysis revealed 8344 confirmed cases in 35 of the 36 states (with the federal capital territory inclusive), 249 fatalities, 2385 discharged cases, 48544 laboratory testing, 5710 total active cases, a mortality rate of 0.12 per 100,000 population, and a Case Fatality Rate (CFR) of 3. It further showed an increased number of confirmed cases in densely populated states. Transmission via contact with infected persons accounted for 23% of a confirmed case. Additionally, 17% (circa) of the tested population were confirmed positive.

Conclusion: Causation and spread are attributed to travel and contact risk factors. Early epidemiological patterning occurred along population density and outdoor exposure lines. Aggressive and continuous testing would reveal more cases especially asymptomatic cohorts in the population.

The effects of heat sources (oven, charcoal and stove) on roasted mackerel fish was investigated on proximate composition and sensory evaluation of roasted mackerel fish (Scromber scombrus). The fish sample was thawed, cut, eviscerated, washed with brine solution and roasted at a temperature of 75°C for 5 hours using oven, charcoal and stove as heat sources. Minor variations were obtained in crude protein, ash, fat, moisture and crude fibre contents amongst the roasted fish samples, while significant variation (p<0.05)was observed between the raw and roasted samples. The nutritive value of roasted fish improved as a result of the smoking process. In all the treated samples, the percentage of total protein, lipid and ash contents increased due to water loss during smoking. High value of ash was seen in experimental charcoal and stove heat sourced fish (15.86 & 14.56% respectively). Protein was retained better in oven sourced (49.17%) fish more than other sources used. The result of the sensory evaluation shows clearly that there was no significant difference in the level of acceptability of the three samples. The mean scores showed that all the characteristics of the products were moderately liked. Mean scores for overall acceptability indicates that the products were generally well accepted. Although the oven heated sample was more acceptable than other heat sources.

DOI: 10.9734/cjast/2020/v39i2630901

In this work a new representation of quantum mechanics, that is, the electromagnetic field representation, is proposed, which is different from the Schr dinger`s equation and Heisenberg`s Matrix. It is pointed out that even though the results from Schr dinger`s equation, Heisenberg`s Matrix and electromagnetic field representation in describing the quantum system are the same, the principles and procedures in describing the quantum system are totally different. The further result regarding the application of the electromagnetic field representation of quantum mechanics to different atomic and molecular systems will be presented later.

The present investigation for various genetic parameters was done for twenty-two lowland rice genotypes in R.C.B.D. with three replications at Rice Breeding Section, Pusa Farm, Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. Analysis of variance revealed significant differences (P-value =0.01) among genotypes for all the characters. Brasali was the highest yielder suggesting that it can be used for crossing programme for improvement in yield. The phenotypic variance was higher than corresponding genotypic variances for all the characters studied. Genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were highest for grain yield per plant followed by1000 grain weight, plant height, number of panicles, root volume, leaf length and days to 50 % flowering revealing that sufficient variability was present in the gene pool for these characters. Thus, there is ample scope for genetic improvement of these traits through selection. The broad sense heritability ranged from 23 % (panicle length of main axis) to 97% (1000 grain weight). High heritability was obtained for most of the characters except for panicle length of main axis and kernel width. High heritability accompanied with high genetic advance as percent of mean was recorded for days to 50% flowering, plant height, root volume, number of panicles, 1000 grain weight, leaf length and grain yield per plant. High values of GCV, PCV, heritability and genetic advance as percent of mean observed for various characters indicate that these traits can be used as selection indices for yield improvement.

Timely sowing is a critical factor in realizing the yield as it ensures the vegetative growth to crop up during a period of satisfactory temperatures and fits the cultivar maturity length and growing season. In the present investigation, 38 cold tolerant rice genotypes were studied under delayed sowing conditions at College Farm, Professor Jayashankar Telangana State Agricultural University, Hyderabad. The genotypes were evaluated for yield attributing traits with a view of understanding the extent of variability and diversity present among the genotypes that could be suitable for delayed sowing conditions with cold tolerance. Analysis of variance (ANOVA) indicated significant differences for all the characters with high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values for tillers per plant, spikelet fertility, filled grains per panicle and seed yield per plant. High heritability coupled with high genetic advance as percent of the mean was observed for plant height, spikelet fertility, filled grains per panicle with higher variability indicating the presence of fixable gene action which may suggest a reliable crop improvement through selection of these traits. As association analysis could help the breeder to design selection strategies to improve grain yield, correlation studies were carried out which revealed the trait to be having positive relation with all the traits except panicle exertion and panicle length. Path coefficient analysis showed all the traits except panicle exertion and test weight to be exhibiting a direct positive effect on yield, selection for which should be emphasized on these positively associated traits for yield enhancement. Principal component analysis and D2 analysis together determined plant height, grain yield, panicle exertion, panicle length and yield per plant having higher contributions to the total variability, which could be taken into consideration in rice breeding programmes for further improvement in production.

The productivity of chickpea has declined considerably during the last three years in rainfed black soils of western part of Kurnool district due to the aberrations in the rainfall pattern, high cost of cultivation, pest & disease incidence and wild deer problem. To overcome these production constraints Cluster Frontline Demonstrations in safflower played major role with introduction of new safflower variety ISF-764.Cluster Frontline Demonstrations were conducted in safflower in 30ha area in 2017-18 and 40 ha in 2018-19 by Krishi Vigyan Kendra Banavasi. ISF-764 (T3 demonstration) performed better even in dry spell conditions compared to chickpea .Cost of cultivation in both ISF -764 (demonstration) and PBNS-12 (T2check) was low (18,300 Rs/ha) compared to chick pea (35,500 Rs/ha) variety JG-11(T3farmers Practice). Chickpea equivalent yields of safflower was 1339 and 803 (kg/ha) in demonstration and check and 720 kg/ha in farmers practice with 86 and 11.6 % improvement in yield. Extension gap for ISF 764 and PBNS-12 were 619 & 83 kg/ha respectively. The technology index was lowest in ISF-764 (21.8) as compared toPBNS-12 (57.12) and JG -11 (58 .8) which indicates the highest feasibility of the demonstrated technology. The net returns (37,950 Rs/ha) and benefit cost ratio (3.07) were highest in ISF -764. Hence Safflower variety, ISF 764 is highly suitable for rainfed black soils of Kurnool district of Andhra Pradesh.

Climate variability has been and continues to be, the principal source of fluctuations in global food production in countries of the developing world and is of serious concern. Agriculture, with its allied sectors, is unquestionably are highly dependent on weather conditions, any weather aberrations cause atmospheric and other forms of stress and in turn, will increase the vulnerability of these farmers to economic losses. Process-based models use simplified functions to express the interactions between crop growth and the major environmental factors that affect crops (i.e., climate, soils, and management), and many have been used in climate impact assessments. The climatic scenario from A1B scenario 2011-2090 extracted from PRECIS run shows that overall maximum and minimum temperature increase by 5.39°C (±1.76) and 5.08°C (±1.37). A decrease of about 20 quintals was recorded when maximum temperature was enhanced by +4°C and about 10 quintals decreased at +2°C. Enhancement of minimum temperature by +3°C shows a decrease of about 16 quintals in tops weight. Combination of both minimum and maximum temperature remarkably decreased grain yield at (maximum & minimum +2°C) up to 25.41%. Max. temperature lead to staggering in the irrigation water productivity, however, a consistant increase in the irrigation water productivity was realised with an increase in minimum temperature. Dry matter productivity of 50 kg DM /ha/mm [ET] was observed with the increase of 1°C in both Max. and Min. temperatures and  the lowest value of (16.7 kg DM /ha/mm[ET]) was recorded when the crop is supposed to grow at enhanced level maximum temperature by +4°C both maximum and minimum temperature. Increase in the both max and minimum temperature by +1°C lead to maximum irrigation water productivity of 22.4 (kg[yield]/ha/mm[irrig]) and the lowest irrigation water productivity of 16.7 (kg[yield]/ha/mm[irrig]) was registerd when both max. as well as min. temp. was raised by +4°C minimum temperature.

The K-status in soils and its availability to plants has close relationship with field capacity or saturated conditions. Hence, there is a need to know the available K status through saturation extract and other parameters governing K-availability which bears close relation to normal field situation under which plants are grown. To improve the efficiency of ammonium acetate method by saturation extract method, saturation extract parameters were studied in vegetable growing soils of Ranga Reddy and Mahaboobnagar districts of Telangana and are correlated with forms of potassium, soil physical and chemical properties to know the importance of these parameters in release and availability of K to plants. The saturation extract obtained from the soils was analysed for available potassium and Ca + Mg values. Different parameters of the saturation extract viz., CRK, BCK and USQI factor were calculated to know the availability of potassium to plants. Results of correlation between BCK and USQI with exchangeable and non exchangeable K showed that these parameters influence the release and availability of K to plants and also the correlation with soil characteristics clearly indicate that the  quantity factor Kam, KL and intensity factors PBCK, BCK  are important to assess available K status. These parameters derived from K extracted by NN NH4OAc and concentration ratio of K in the saturation extract of soil i.e. BCK and USQI factor served as better indices for assessing the K supplying status of soils than K extracted by different chemical methods.
