Development of a scale to measure impact of Transfer of Integrated Crop Management Technologies developed by M.P.K.V., Rahuri

Paper ID- AMA-01-01-2023-11929

Scale development and validation are critical to much of the work in the social, and behavioural sciences. For systematic and accurate measurement of impact of Transfer of Integrated Crop Management Technologies developed by MPKV Rahuri under Rashtriya Krishi Vikas Yojana (RKVY) on its beneficiaries the scale was constructed by following the [14] of summated ratings suggested by (citation) Edward. Out of the three phases, in the first phase 163 items were generated for covering all aspects of socio-economic impact of Transfer of Integrated Crop Management Technologies developed by M.P.K.V., Rahuri on beneficiaries collected from the various sources such as literatures, extension personnel’s, scientists from agricultural universities and experts from KVK’s. These were segregated under three sub-headings namely economic impact, social impact and agricultural impact and the validity of their content is assessed. In the second phase, the scale was constructed by item selection, pre-testing the questions, administering the survey, reducing the number of items, and understanding how many factors the scale captures. In item selection 163 items were sent to 100 judges comprising of senior faculties and experts in the field of agriculture. After analysis of relevancy preference score given by expert and were edited by following the 14 informal criteria suggested by [4]. One hundred and thirty-three items having mean score value being equal to or higher than the overall mean score was selected for item analysis. These items selected through judge’s opinion were administered to a random sample of 30 farmers from non-sample area. The items are rated by the farmers on five-point continuum vis-a-vis strongly agree, agree, undecided, disagree, strongly disagree. Based on total individual score, the judges were arranged in descending order. Upper and lower 25 per cent of the judges were used as criteria groups to evaluate the individual statements. The critical ratio i.e., the t-value was calculated, and items were selected on the basis ‘t’ value equal to or greater than 1.75. Ninety-four items were selected after ‘t’ value calculation. In the third phase, we carried out scale evaluation, tested and checked the reliability the number of dimensions and their reliability and validity is assessed. The scale with 94 items thus developed was administrated to the 30 farmers who were neither previously interviewed nor had chance to come in the final sample. After period of 15 days the same 30 farmers undertook the test. Thus, we obtained two sets of scores with a very high correlation (r = 0.95) which indicated that the scale is highly reliable. The content validity of the scale was determined through a group of experts as suggested by [11] and it was ensured that items covered the various aspects of socio-economic impact.

Effect of natural plant extracts on wood degradation and chemical constitute after decay test of Pinus roxburghii wood

Paper ID- AMA-31-12-2022-11928

Development of natural wood preservatives for the protection of wood against to the wood degrading agencies. Present investigation was designed to determine the feasibility of natural plant extracts on wood degradation and chemical constitute after decay test of Pinus roxburghii wood. During the study two plants species were selected for the wood preservation in this contest plant extract was extract with the help of two different solvent methanol and petroleum ether from the Acorus calamus and Parthenium hysterophorus. Wood samples treated with extract at various concentration (0.25%, 0.50%, 1.00%, 1.5%, 2%) and one control and exposed with white fungi (Trametes versicolor) for the three months. Treated wood samples show minimum (13.46%) degradation with methanol extract of P. hysterophorus and 13.63% degradation with petroleum ether of A. calamus treated wood sample and maximum degradation was noticed in untreated wood samples, degradation of wood sample was increase with decrease the plant extract concentration. At the same chemical properties of wood sample were also examine after decay test and find out that the maximum clod and hot water soluble extractives and alcohol benzene soluble extractives, lignin and holocellulose content were notice maximum in treated wood sample and decrease with decreasing in the plant extract concentration. Novelty of the study is selected plats show the antifungal property against to the fungi. It is help full in the wood preservation without effect the environmental health and human being.

Application of Quasi Z-source Multilevel Inverter for Stand-alone PV system

Paper ID- AMA-31-12-2022-11927

This paper elaborates on the application of PV based quasi-Z-source Multilevel inverter(qZMLI) for the standalone system supplying AC loads. qZMLI is a preeminent topology that boost/buck the input voltage using shoot-through state and gained popularity due to its high reliability, low cost and compactness. This paper focuses on the design of the entire PV system interfaced with qZMLI. Determination of power consumption of loads, sizing of panels, sizing of inverter, sizing of battery and sizing of charge controller are elucidated alongwith calculations. The successful testing is carried out and the results are presented.

Impact of weather factor on shoot borer of sugarcane incidence in new cauvery delta region of Tamilnadu and its management.

Paper ID- AMA-30-12-2022-11926

Surveys and surveillance were conducted in sugarcane fields both in plant and ratoon crops distributed in Orthanadu and Vallam block in New Cauvery delta area of Thanjavur dictrict during three consecutive years 2019- 22 with an objective to assess the incidence of Early shoot borer in New Cauvery delta area of Thanjavur dictrict. Fortnightly fixed plot observation was taken. The Maximium and minimum temperature, RH and quantity of rain and rainy days also recorded daily and consolidated on monthly basis and weather parameters were correlated with the incidence of Early shoot borer. The results revealed that the maximum incidence of early shoot borer 36.5 percent. The result shows that the average temperature is positively correlated (r = 0.6690) with incidence of shoot borer and negatively correlated with rainfall (r = -0.7134) and humidity (r = -0.0903). In the field trial combination of Single bud treated with Trichoderma asperellum (TNAU)@ 4 g l-1 + soil application @ 2.5 kg ha-1 along with S4 (Intercropping with sunhemp + installation of sex pheromone traps @ 50 ha-1 (mass trapping) + need based spraying of Cartaphydrachloride @ 1kg ha-1) effectively increases the germination percentage of 85.16 % and decrease the shoot borer incidence by 45 percent which is significantly different from other treatment.

EFFECT OF BIO-FERTILIZERS AND SILICON PRODUCTS IN INDUCING DEFENSE IN RICE AGAINST WHITE BACKED PLANTHOPPER

Paper ID- AMA-25-12-2022-11924

The field experiment was conducted during kharif, 2016 and kharif, 2017 to examine the effect of organic and inorganic products of silicon and bio fertilizers in inducing resistance against white backed plant hopper (WBPH) on rice. It was observed that silicon taken by rice plants in various treatments declined the population of WBPH as compared to control treatment. The treatment RHA+PF+KSB (T8) was the most effective treatment in reducing infestation followed by CaSiO3+PF+KSB (T5) and CaSiO3+KSB (T4), respectively. Silicon content was observed to be more in T5 followed by T8 and T4 treatments. The grain yield was highest in T5 (4475.83 kg/ha) followed by T8 (4173.33 kg/ha) and T4 (4103.17 kg/ha). The treatment T5 contained highest percentage of Si i.e., 7.71 % and 6.89 % at vegetative stage and reproductive stage, respectively. WBPH incidence at both the stages was significantly and negatively correlated to Si content (r= -0.714 and -0.770, respectively).
