Crossandra is an important commercial
flower, mainly grown in India, tropical Africa
and Madagascar. The flowers are commonly
used for hair adornment. Though not fragrant,
flowers are very popular because of its
attractive bright colour, light weight and good
keeping quality. These are used for making
garland, either alone or in combination with jasmine flowers. Using Crossandra flowers in

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

right time at the right dose.
The plants become stunted with pale coloured flowers and less yield.
1 month after planting 20 – 25 kg DAP and 12 – 15 kg potash as top
dressing.
If the flowers are still small with less yield, another dose of top dressing is
given.
16. WEEDING
Weeds become problem in early stage
of cultivation gomphrena .
If weeding is not taken at proper time
growth and productivity will be
markedly reduced.
HARVESTING

17. DISEASES AND PESTS
DISEASES
Leaf spot disease is caused by the fungus Cercospora gumphrenae
The plants are very susceptible to tomato bushy stunt virus infection
when grown at high temperature and long photoperiod
G. globosa is susceptible to yellowing of veins disease, causing
stunted growth and deterioration in bloom quality.
It is easily transmitted by white fly (Bemisia tabaci).
