Grafting Method - Inarching or Approach Grafting

Image
Inarching or Approach Grafting Unlike other grafting operations, in inarching the scion is attached to the stock while it is still attached to the parent plant. Round the world, the method has been extensively used in the vegetative propagation of mango. The method involves potting healthy one-year- old seedling in earthen pots, which are usually 12 in deep and 8 in wide at the top. The earth ball along with root system is kept intact and placed in the pot. The unfilled space in the pot is then filled with a mixture of well- rotted manure and canal silt. The soil is firmly pressed around the earth ball and the transplanted seedlings are then watered. Potting of seedlings is usually done one month ahead of actual inarching operations. This allows sufficient time for the seedlings to set before grafting. Inarching can either be done in the spring months or in the rainy season. July and August are preferred over the spring season because after inarching operations in the spr...

Tree Planting in Problem Soils

Image
Tree Planting in Problem Soils The ultimate aim of this exercise is to think of some appropriate measures and treatments that would minimum the effects of prevailing harmful factors and therefore maximum plant survival and enhance their growth rate. A normal form area develops into a problem area when shortage or excess of any or some environmental factors prohibit plant establishment and severely retard their growth. Such factors vary from one locality to another and can be any one of the numerous environmental (climatic, edaphic or bio tic) factors or their combination.

Microbiomes Could Hold Keys to Improving Life

Microbiomes Could Hold Keys to Improving Life Microbial life forms including viruses, bacteria and fungi are the most diverse and abundant organisms on earth. They have shaped our evolutionary origins for billions of years and continue to have widespread impact on the planet, its environment and the species inhabiting it. Together, they make up microbiomes that influence each other, the environment, and the host organisms that these microbial communities thrive in. The UMIC foresees that the microbiomes populating our planet and its many diverse species and environments could be leveraged through genetic engineering for applications that improve the greater good, and that many milestones could be reached on this front within ten years. "Microbes are everywhere. Therefore understanding microbiomes, whether they be the ones that live in and on our bodies or the ones in the environment, is essential to understanding life," said Silver, who in addition to being one...
