Manoj Kumar presented a seminar on weed management practices in mungbean under agri-horti systems. Agri-horti systems combine agricultural crops with fruit trees on the same land. Weeds compete with crops for resources and reduce yields. The presentation evaluated different weed management methods including preventative practices, cultural control, mechanical removal, and chemical herbicides. Hand weeding was found to be the most effective method for small areas, while the herbicide Imazethapyr provided good weed control and improved mungbean yields in agri-horti systems.

4. INTRODUCTION
In india more than 70% population of this region depends
upon agriculture for livelihood while the land suitable for
agriculture is limited .
The multifarious trees deliberately retained by the farmers
on the farm bund forms the agroforestry combinations.
Weed infestation is one of the major factors limiting crop
productivity. Weeds not only reduce the yield but also make
the harvesting operation and ensuring food security ,effective
weed management is very essential.

AGROFORESTRY
Agroforestry is the any sustainable land-use system that
maintains or increases total yield by combining food crop
(annuals) with tree crop (perennials) and/or livestock on
the same unit of land ,either alternately or at the same time
.

6. BENEFIT OF AGROFORESTY
Reduction of pressure of forest.
Increment in an output of food ,fuel wood, fodder ,
timber,gum etc.
Reduction of surface run-off, soil erosion and leaching
Increment in soil nutrients through addition and
decomposition litter fall.
8. WHAT IS WEED?
o “ Weed is an unwanted plant growing where is
not desired.’’
o Weeds are unwanted or undesirable plants compete
with crops for water, soil nutrients, light and space (i.e.
CO₂) and thus reduce crop yields.

10. WEED COMPETITION
Weeds compete with crop plants for moisture,
nutrients,light and space, thereby depriving the crop of vital
inputs.
Therefore, weed competition is one of the most
important constraints in crop production.

22. CONCLUSION
Mechanical weed control method (hand weeding) is the
best method of weed control and improving mungbean yield
for the small areas in agri- horti system.
Chemical weed control i.e. Imazethapyr was most
effective in suppressing weeds and improving mungbean
yield in agri- horti system.
