This document summarizes a seminar presentation comparing the performance of different mechanical implements for weed control in sugarcane. It describes experiments evaluating the weeding efficiency, plant damage, fuel consumption, and costs of operations using a rotary tiller, cultivator, rotavator, and manual weeding. The results showed that a single or double pass with the rotary tiller was the most effective mechanical method based on higher weeding efficiency and lower plant damage compared to the cultivator and rotavator. However, manual weeding had the highest weeding efficiency and lowest cost of operation, though it required more labor.

Designing of sprinkler irrigation systemEngr Mehmood
Sprinkler irrigation is a method of applying irrigation water that is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops that fall to the ground.

Sugarcane (Saccharum officinarum) is the main sugar-producing crop that contributes nearly 78.2% to the total sugar pool at the global level. It is the prime source of sugar in India; also holding the prominent position as the commercial cash crop. Power weeder has been evaluated for its performance and suitability in sugarcane crop. The evaluation was conducted at different moisture contents of soil i.e., 30,45 and 60 days after sowing(DAS) at different speeds of weeder.

Anaerobic digestion of animal manure has generally been limited to wet digestion where total solids are less than 12%. This has restricted adoption of biogas production primarily to dairy and hog operations, or required substantial water usage to dilute manures with higher solids content. The DRANCO-Farm dry anaerobic digestion technology processes solid manures and other dry crop residues on a continuous basis with solids content in the digester up to 45%.
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 Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

SUGARCANE PRODUCTIVITY IN INDIA
9. • It is observed that the productivity of sugarcane ,
national avg, is stagnating around 65-70 tons/ha
Because of –
-Non implementation of practices
-Shortage of labour
• It is reported that yield loss caused by weeds may
range from 15-75% depending upon nature and
intensity .(Olaoye and Adekanye, 2006)
• There is need to focus on weed management
practices
10. Weed control in sugarcane-
• It is perennial crop and remains 3-4 years in same
field. So, all types of seasonal, perennial and annual
grow in field.
• Weeds emerge during rainy season- echionochola
colonum and E.crusgalli(grasses)
• Methods used for weed control are-
Manual Weeding
Mechanical weeding
Chemical weeding
11. • Manual weeding, which is common practice followed
in different regions.
• Labour requirement for weeding/ interculture
operation ranges between 400-600 man-hr/ha.

32. CONCLUSION
Among the mechanical methods, treatment T1D and T1S was
found more effective compared to treatments T2 and T3 based
on higher weeding efficiency and plant damage.
Treatment T1S and T3 was found equally effective as far as
weeding efficiency concern.
Conventional method was found expensive than mechanical.
Use of rotary tiller, among the mechanical methods can be
recommended to farmers for efficient weed management even
though cost of operation is high.
Advantage is that as it covers single row of the crop it can be
used even at later stage when plant grows tall enough.
