Nutrient Content and Nutrient Uptake of Rice by The Impact of Inorganic, Organic, and Biological Sources of Nutrients in An Inceptisol Soil of Tamil Nadu
Using the rice variety ADT-37, a field experiment was conducted in the rabi season of 2023 in Tamil Nadu. The scope of the study is to find out the impact of different sources of nutrients on nutrient content and uptake of rice. Most of the previous research work has combined inorganic and organic sources, or inorganic alone or organic alone or anyone with biological. Here we have included inorganic, organic and biological sources of nutrients. The experiment included of nine treatments viz., T1 – Control, T2 - 100% RDF, T3 - 125% RDF , T4 - 100% RDF + Press mud @ 10 t ha-1 + 2% Zinc Solubilizing Bacteria, T5 – 100% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T6 – 100% RDF + Coirpith Compost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T7 – 125% RDF + Press mud @ 10 t ha-1 + 2% Zinc Solubilizing Bacteria, T8 – 125% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T9 – 125% RDF + Coirpith Compost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria. The result concluded that 125% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria (T8) resulted maximum values in nutrient content and significantly higher in nutrient uptake values
Design of Low-Cost Hydroponic Technology for Cultivation of Leafy Vegetables for Human Food Security in a Cold Desert Area of the Trans-Himalayan Range
For many decades, food security has been a worldwide concern. The present research aimed to examine an efficient technique for planting system i.e. hydroponic (a soil less system of farming) and statistical experimental design approach was used to compare the growth of different Leafy Vegetables (Spinach and Lettuce Varieties) in the Cold Desert Region of Trans Himalaya under the designed hydroponic system. The results showed that the leafy vegetable variety that were grown in the NFT system, exhibited significant differences in above attributes. The BC ratio of nutrient solution was found to be four times higher
Android Operating System and its Security Issues
Android is a Mobile and Tablet Operating System premised on the Linux kernel owned by Google. The ultimate innovative feature of Android Operating System is open source due to this anyone can publish their applications freely on the Android market. This openness introduces the broad number of developers which utilize this platform, but it comes with the hazard that user may download malicious software which is written by network hackers and harm to its privacy. This requires the study of the Security Mechanisms for Android and to make it easy and user-friendly to make the user aware of areas where he has to be cautious. This paper gives an idea about the architecture of the Android operating system, security features of an android, security issues faced by the Android and solutions for security issues of the Android operating system
Impact of Inorganic, Organic and Biological Sources of Nutrients on Growth and Yield of Rice in an Inceptisol Soil of Tamil Nadu (Navarai Season)
A field experiment was carried out during the Navarai season (2022) using rice variety ADT - 37 to assess the impact of inorganic, organic, and biological sources of nutrients on the growth and yield of rice in an Inceptisol soil of Tamil Nadu. The experimental soil was clay loam in texture and had a pH-8.10, EC-0.7 dSm-1, and available NPK of 186.20, 23.30, and 192.25 kg ha-1, respectively. The experiment comprised of nine treatments viz., T1 – Control, T2 - 100% RDF, T3 - 125% RDF , T4 - 100% RDF + Press mud @ 10 t ha-1 + 2% Zinc Solubilizing Bacteria, T5 – 100% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T6 – 100% RDF + Coirpith Compost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T7 – 125% RDF + Press mud @ 10 t ha-1 + 2% Zinc Solubilizing Bacteria, T8 – 125% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria, T9 – 125% RDF + Coirpith Compost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria. The results of the experiment revealed that application of 125% RDF + Vermicompost @ 6 t ha-1 + 2% Zinc Solubilizing Bacteria (T8) recorded higher values in growth and yield parameters viz., plant height (106.8 cm), Number of productive tillers hill-1 (14.5), Leaf area index (8.02), chlorophyll content (1.285 mg g-1) Number of panicles m-2 (585), Number of grains panicle-1 (227) Dry matter production (5720 kg ha-1), Grain yield (6293 kg ha-1) and Straw yield (8943 kg ha-1)
Method Development and Validation for Determination of Voglibose in Tablet Formulation Using LC-MS/MS
Voglibose is a potent α glucosidase inhibitor, used for the treatment of diabetes mellitus. For quantitative determination of voglibose in pharmaceutical formulations of low doses, simple, sensitive, accurate and precise LC-MS/MS method using electrospray ionization in positive mode was developed and validated. The method was found linear in the concentration range of 25.0-1200 ηg/mL with a correlation coefficient of 0.9998. The limit of detection (LOD) of the method was found to be 1.5 ηg/mL and limit of quantitation (LOQ) was achieved at 3.0 ηg/mL. The recoveries of voglibose from spiked samples at different concentration levels were found in the range of 98-102%. The proposed method was found suitable for quantitation of voglibose and for the determination of uniformity of content of the dosage units of the tablet formulations
Hydroponic Technique: A New approach for Crop Production at Trans Himalayan High-altitude Cold Desert Regions of India
Aims: The trans-Himalayan high-altitude cold desert regions of India is characterized by a rugged topography at an altitude ranging from 2550 to 7742 meters above sea level. It has a vast geographical area of 72976 km2 with very little cultivated area of about 13726 hectare. Hydroponic is a soilless cultivation technique which may produce fresh vegetable in areas where environmental stress (cold, heat, dessert etc.) and limited space or on non-arable land is a major constrains for agriculture production.
Methodology: The experiment was conducted under open natural ventilated double layer polycarbonate green house in cold desert high altitude conditions of Leh, India. The hydroponic structures were designed for crop production (viz. leafy greens, vegetables, fruits etc) in deep water culture (DWC) and nutrient film technique (NFT) hydroponic techniques and compared them with conventional soil grown system. Nutrient solution for growing vegetables was prepared and standardized.
Results: The result obtained has shown that crop yield was significantly higher in hydroponic system as compared to traditional system for all crops. The recorded increase in yield for various crops in hydroponic system compared to soil grown system were: arugula 221%, atriplex 248%, coriander 288%, fenugreek 208%, lettuce 293%, mint 237%, mustard 227%, spinach 294%, cucumber 533%, strawberry 280%, summer squash 229% and tomato 345% which were significantly higher. Hydroponics can be explored to grow vegetables round the year especially for leafy greens. The hydroponic systems may come out as a valuable asset to forward and remote area of trans-Himalayan region for growing fresh vegetables where cultivated land and availability of the water are the limiting factors for crop production
