Effect of Vermicompost and Foliar Application of Zinc on Soil Properties and Nutrients Uptake by Groundnut (Arachis hypogaea L)

A field experiment was conducted to investigate the effect of vermicompost and foliar application of zinc on soil properties and nutrients uptake by groundnut (Arachis hypogaea L.) during 2018-19 and 2019-20. The ten treatments in the experiment viz., T1 (N:P:K, 15:60:30), T2 (N:P:K +Vermicompost), T3 (N:P:K +Vermicompost + Soil Zn 100%), T4 (N:P:K + Vermicompost + Soil Zn 75%), T5 (N:P:K + foliar application of 0.25% ZnSO4), T6 (N:P:K + foliar application of 0.50% ZnSO4), T7 (N:P:K + foliar application of 0.75% ZnSO4), T8 (N:P:K + Vermicompost + foliar application of 0.25% ZnSO4), T9 (N:P:K + Vermicompost + foliar application of 0.50% ZnSO4) and T10 (N:P:K + Vermicompost + foliar application of 0.75% ZnSO4) were replicated thrice under randomized block design (RBD). The results of the experiment revealed that the treatment receiving N:P:K (15:60:30) + Vermicompost (5 t ha-1) + Soil Zn 100% (T3) had significantly higher values of organic carbon (0.56 percent), available nitrogen (156.59 kg ha-1), available P2O5 (50.39 kg ha-1), available K2O (183.14 kg ha-1), Zn (0.65 mg kg-1), lower values of pH (7.34), EC (0.22 dSm-1) and higher values of nutrients uptake over control (T1), while at par with the application of N:P:K + Vermicompost + Soil Zn 75% (T4), N:P:K + Vermicompost + foliar application of 0.25% ZnSO4 (T8), N:P:K + Vermicompost + foliar application of 0.50% ZnSO4 (T9) and N:P:K + Vermicompost + foliar application of 0.75% ZnSO4 (T10)

Insulin resistance in euglycemic cirrhosis

Abstract Background Insulin resistance (IR) is associated with hepatic fi brosis and cirrhosis, regardless of its etiology but the mechanism of hyperinsulinemia in cirrhosis is still unclear. Th e current study was designed to assess hyperinsulinemia and pancreatic β-cell function in euglycemic cirrhosis of varied etiology

An electromagnetic extension of the Schwarzschild interior solution and the corresponding Buchdahl limit

We wish to construct a model for charged star as a generalization of the uniform density Schwarzschild interior solution. We employ the Vaidya and Tikekar ansatz (Astrophys Astron 3:325, 1982) for one of the metric potentials and electric field is chosen in such a way that when it is switched off the metric reduces to the Schwarzschild. This relates charge distribution to the Vaidya–Tikekar parameter, k, indicating deviation from sphericity of three dimensional space when embedded into four dimensional Euclidean space. The model is examined against all the physical conditions required for a relativistic charged fluid sphere as an interior to a charged star. We also obtain and discuss charged analogue of the Buchdahl compactness bound

Effect of Vermicompost and Foliar Spray of Zinc on Growth, Quality and Productivity of Groundnut (Arachis hypogaea L.)

A field experiment was conducted during 2018-19 and 2019-20 to study the effect of vermicompost and foliar spray of zinc on growth, quality and productivity of groundnut (Arachis hypogaea L.) The experiment comprising of ten treatments viz., T1 (NPK), T2 (NPK +VC), T3 (NPK +VC+ Soil Zn 100%), T4 (NPK + VC+ Soil Zn 75%), T5 (NPK + foliar spray of 0.25% ZnSO4), T6 (NPK + foliar spray of 0.50% ZnSO4), T7 (NPK + foliar spray of 0.75% ZnSO4), T8 (NPK + VC + foliar spray of 0.25% ZnSO4), T9 (NPK + VC + foliar spray of 0.50% ZnSO4) and T10 (NPK + VC + foliar spray of 0.75% ZnSO4) were replicated thrice and evaluated in the randomized block design (RBD). The experimental soil was loamy sand in texture, low in N, high in available P and medium in K. Groundnut variety, RG 559-3 was tested. The results of the experiment revealed that significantly higher values of growth parameters viz., plant height and number of root nodules plant-1; yield viz., pod yield (44.3, 47.2 q ha-1) and haulm yield (54.03, 58.8 q ha-1); quality parameters viz., oil content and protein content were recorded under the treatment receiving NPK (15:60:30) +VC (5 t ha-1) + Soil Zn 100% (T3) over control (T1) while at par with the application of NPK + VC+ Soil Zn 75% (T4), NPK + VC + foliar spray of 0.25% ZnSO4 (T8), NPK + VC + foliar spray of 0.50% ZnSO4 (T9) and NPK + VC + foliar spray of 0.75% ZnSO4 (T10)

Recycling of Crop Residues for Sustainable Soil Health Management: A Review

Burning of crop residues have become a challenging issue for scientist’s community as well as policy makers worldwide as it directly affects environment, soil health and the productivity of crops. Microbial mediated recycling of crop residues into an amorphous dark brown to black colloidal humus like substance under conditions of optimum temperature, moisture and aeration is need of the hour. Crop residue recycling increases sequestration of organic carbon in soil which ultimately leads to improve soil physical, chemical and biological health. Organic carbon acts as a reservoir for nutrients, needed in crop production. Crop residue management recycling is a cost-effective option for minimizing agriculture's input with maximizing output. Besides supplying nutrients to the current crop, their residual effects on succeeding crops in the system are also important. This review emphasizes on crop residue recycling by different techniques. This review paper maybe helpful to the policy makers and researchers

Effect of the COVID-19 Pandemic on Respiratory Diseases and Their Economic Impacts

COVID-19 is an airborne respiratory disease that mainly affects the lungs. To date, COVID-19 has infected 580 million people with a mortality of approximately 7 million people worldwide. The emergence of COVID-19 has also affected the infectivity, diagnosis, and disease outcomes of existing diseases such as influenza, TB, and asthma in human populations. These are airborne respiratory diseases with symptoms and mode of transmission similar to those of COVID-19. It was speculated that the protracted nature of the COVID-19 pandemic coupled with vaccination could impact other respiratory diseases and mortality. In this study, we analyzed the impact of COVID-19 on flu, tuberculosis (TB), and asthma. Our analyses suggest that COVID-19 has a potential impact on the mortality of flu, TB, and asthma. These impacts vary across before the COVID-19 era, during the peak period of the pandemic, and after vaccinations/preventive measures were implemented, as well as across different regions of the world. Overall, the spread of flu generally reduced during the pandemic, resulting in a reduced expenditure on flu-related hospitalizations, although there were sporadic spikes at setting times. In contrast, TB deaths generally increased perhaps due to the disruption in access to TB services and reduction in resources. Asthma deaths, on the other hand, only marginally varied. Collectively, the emergence of COVID-19 added extra cost to the overall expenditure on some respiratory infectious diseases, while the cost for other infectious diseases was either reduced or somewhat unaffected
