SCREENING OF GROUNDNUT VARIETIES/ GENOTYPES FOR RESISTANCE AGAINST APHID APHIS CRACCIVORA AND LEAFHOPPER EMPOASCA KERRI
The field experiment was conducted for two consecutive years 2020 and 2021 during the Kharif, season at Agronomy Farm, S.K.N. College of Agriculture, Jobner (Rajasthan). Out of fifteen genotypes of groundnut screened against aphid and leafhopper four genotypes viz., RG-632-1, RG-559-3, Girnar-4 and RG-633 were categorized as least susceptible against both the insect. Whereas, RG-622-5, RG-382, RG-638, RG-628, RG-621, TG-37-A and RG-639 as moderately susceptible and RG-624, RG-425, RG-510 and RG-578 as highly susceptible to aphid infestation. Eight genotypes viz., RG-382, RG-638, RG-622-5, RG-628, TG-37-A, RG-639, RG-425 and RG-621 were moderately susceptible and three genotypes viz., RG-624, RG-510 and RG-578 were highly susceptible to leafhopper infestations.
Studies on Iron fractions under P × Fe interaction in Maize
Both in light and heavy textured soil, the exchangeable-Fe was decreased significantly with increasing level of P application over control as well as at each successive level of P application. The exchangeable-Fe is the least amongst the inorganic Fe fractions extracted and, on an average, constituted only about 0.02% of total-Fe extracted from the soil irrespective of soil texture. The carbonate-Fe was increased significantly with increasing level of P application up to its highest level over control and also at each successive level. With respect to Fe application, the carbonate-Fe fraction was also found to increase significantly with increasing level of soil application of Fe while foliar spray of Fe did not show any significant influence on carbonate-Fe fraction. This fraction also accounted about 0.02% of total-Fe extracted. With regard to P application, Fe-Mn oxide fraction of light and heavy textured soils was increased significantly with increasing level of P application over control. This fraction constituted on an average 2.6% of total-Fe extracted from the soil. In both light and heavy textured soils, the OM-Fe content decreased significantly with increasing level of P application over control. On an average, this fraction accounted 1.25% of total-P fraction extracted irrespective of soil texture. There was no significant effect of P and Fe application on residual-Fe fraction of light and heavy textured soils. This fraction constituted 2.7% of total-P extracted from soil without consideration of soil texture. Over all study endorse a negative interaction of phosphorus and iron.
Studies on Phosphorus fractions under P × Fe interaction in Maize
Limited information is available on the impact of phosphorus and iron interaction. Therefore, a study was undertaken on sandy loam (light textured) and clay loam (heavy textured) soil in a screen house taking maize as a test crop. In both light and heavy textured soils, Saloid-P content of soil was increased up to highest level (40 mg kg-1) of P application. Application of various levels of Fe either as soil or foliar spray did not influence significantly the Saloid-P content of both type of soils. In light textured soil, application of phosphorus significantly affected the Al-P in the soil up to the highest level. Application of Fe either as soil or foliar spray did not improve Al-P fraction significantly, rather, numerically it was decreased as compared to control. There was an increase in Al-P content of heavy textured soil with increasing level of P application. The results did not show any significant differences in Al-P as a resultant of Fe application either as soil or foliar spray. Under both light and heavy textured soils, there was numerically increase in Fe-P with the increase in P level over control, while Fe application resulted in decrease in its fraction with increase in Fe level. With the increasing rate of P application in light and heavy textured soils, Ca-P fraction was also increased. Non-significant effect of Fe application either as soil or foliar spray was observed for Ca-P content. It decreased with increasing level of Fe application over their respective controls under both light and heavy textured soils. Phosphorus and Iron are found to be negatively interacting at higher level of application of iron.
An experimental comparison of meter calibration used in a photovoltaic water pumping system installed in an arid environment
Energy and water are crucial for humans in all their activities. In rural areas, irrigation is a surviving key where sustainable approaches like solar water pumping systems are required to meet this demand. One of the crucial challenges in the hydraulic field is the flow rate measurement with high accuracy. The exact estimation of the water flow rate pumped using a solar photovoltaic water pumping system is essential to evaluate the system's performance. This paper presents an analytical method to study a comparative analysis of the results of the system measurement errors. The experimental data are collected from our pumping system located in Adrar city (Algeria). The performance is analyzed using the measured water flow rate data using three different meters, one ultrasonic and two turbine meters, where a turbine meter is used as a standard meter. The test was done in May 2019.
Interactions between domestic income and Sectoral transformation: A time series analysis of carpet industry in the Union territory of Jammu and Kashmir
Jammu and Kashmir is known to the world for its cultural heritage and shares much resemblance to the Middle Eastern countries like Iran. The cultural richness of the valley is showcased through various mediums and carpet is one the main reflections of it. The study attempted to analyze the impact of domestic income, horticulture output, political conflict and population growth on the carpet industry of Jammu and Kashmir. Taking annual time series data from 1990 onwards, the autoregressive distributed lag (ARDL) model is employed to estimate the long run and short run results. The empirical results indicate that domestic income negatively affecting the output of the carpet industry both in the long run as well as in the short run. Further, some sort of structural shift from primary commodities to secondary and tertiary sectors is visible from the econometric results. It is also revealed by the results that during political upheaval and lockdowns, the carpet industry provides a lifeline to support the local employment. The paradoxical findings arise due to fact that clampdown and terror has forced the people to look for safer jobs and at the same time to be closer to their families and relatives. The horticulture activities compliment the carpet output by releasing the labor in slack seasons. The whole diagnostic testing deducts that our model is robust and statistically significant. The theoretical properties driven out of this study can be used for policy analysis.
