  AGRIVOLTAICS AND INDIA   Introduction : Availability of land is becoming an issue in view of growing urbanization and construction activity. Here’s were the Agrivoltaics or Agro photovoltaics (APV) system of practice comes into action to help us to build the new clean and green phase of cultivation. Let’s see about the APV System in detailed form in the following article. What is Agrivoltaics ?    Agrivoltaics, agro photovoltaics, agrisolar, or dual-use solar is the simultaneous use of areas of land for both solar photovoltaic power generation and agriculture . In simple means, crops that are cultivated underneath the solar panels in a piece of land simultaneously.  -  The “shade tolerant” crops (requiring less light) have to be grown underneath the panels.  -  Vegetable crops are mostly preferred as it requires less light compared to the other field crops.     History :     The technique was originally conceived by Adolf Goetzberger and Armin Zastrow in 1981 , Agrivoltaics can re

  LAC CULTURE   Lac is a resinous substance secreted by a tiny insect called Laccifer lacca (“lac insect”)   Shellac is the purified lac usually prepared in the orange or yellow flakes.  Lac or shellac is used in many ways ·        Commonest use is in polishing wooden furniture. ·        The granules are dissolved in spirit and then are applied in very thin layers on the wooden surfaces ·        In sealing parcels, packets, and envelopes ·        As insulating material in electrical work ·        In making phonograph records (now replaced by synthetic material) ·        In shoe polishes ·        In toys and jewellery Utilization of lac for various purposes has been very ancient in India. A “lac palace” is described in Mahabharata, which was intended to be used for burning the Pandavas alive.

Papaya is otherwise called as Wonder fruit of tropics and subtropics, backyard fruit, breakfast fruit, papaw and tree melon. It has high Nutritive value and it is It is rich in Vitamin A , moderate in vitamin C and rich source of calcium . Most of us know the edible part of papaya is fruit and it is consumed as whole. Other than that we can get extra income by growing papaya. Papain is the enzyme extracted in papaya before its maturity stage. It has many uses , let us discuss more about papain. PAPAIN Papain is an enzyme found in the white fluid (latex) that occurs in raw papaya fruit. It is a protease, meaning it breaks down proteins. Papain contains substances that might help fight infection and heal wounds. Papain extraction  Papain present in the latex tapped from 70-90 days old mature but unripe fruits. Latex is tapped by giving four longitudinal

TH E BLOCKCHAIN TECHNOLOGY IN AGRICULTURE                                              -a Basics in blockchain and their application in Agriculture       BLOCK CHAIN:                   A blockchain is essential and massive digital ledger that records financial transactions. It can also be used to securely keep important and valuable records, protecting them from alteration, left or abuse.      AGRICULTURE:          It is the science or practice of farming, including cultivation of the soil for the growing crops and the rearing of animals to provide food, wool and other products.      BLOCKCHAIN IN AGRICULTURE:          The blockchain technology enables the traceability of information in the food supply chain and thus helps to improve food safety.         It provides secure way of storing and managing data, which facilitates the development and use of data-driven innovation for smart farming and smart index based agriculture insurance.          Now blockchain technol
