ABSTRACT
Since ancient civilization millets have been traditionally cultivated as a staple food in Asia and Africa. After the
popularization of fine cereals such as rice and wheat, the millets lost their popularity and remained confined to a
limited area and production. However, when we talk about nutritional security, millets have immense potential as
they are rich in different amino acids, vitamins, and minerals. Therefore, they are considered “Nutri-Cereals.” Nature
has also equipped them with a high potential to thrive well in resource constraint situations. Hence, considering
the growing ill effects of changing climatic scenarios, their demand is going to be high in the future. As far as the
cultivation of millets is considered, their yield is compromised by several biotic and abiotic stresses. Among the
biotic stresses, weed infestation is one of the most important ones, which drastically reduces the yield of millets.
Millets are slow growers at the early stages of their growth. Hence, if proper and timely weed management strategies
are not taken then weeds deprive the crop of different growth resources such as nutrients, soil moisture, light, and
space which ultimately hamper the yield. Several weed management strategies, namely, pre-emergence herbicides,
and herbicide mixtures have been standardized for weed control in millets. However, limited kinds of literature are
available suggesting the weed management options in millets, post-emergence herbicide options, and integrated
weed management options. Post-emergence herbicides along with other methods of weed control can provide a
season-long competition-free environment to the millet crops which will increase millet productivity. The available
weed management options from different works of literature have been discussed in this article.
1. INTRODUCTION
The first green revolution in our country was concerned with food
security, whereas the second green revolution will be concerned with
nutritional security. Millets are the most important component of
the nutritional security program, which are therefore called “Nutri-
Cereals.” Millets have been cultivated for more than 5000 years in
many parts of Asia and Africa [1]. In addition to being a staple diet
in Northern Africa for thousands of years, millets were also popular
in China and India before fine cereals such as rice and wheat gained
widespread. They are among the earliest cultivable food grains that
humans have been able to identify. Sorghum (Sorghum bicolor), pearl
millet (Pennisetum glaucum), finger millet (Eleusine coracana),
foxtail millet (Setaria italica), little millet (Panicum sumatrense),
barnyard millet (Echinochloa frumentacea), kodo millet (Paspalum
scrobiculatum), and proso millet (Panicum miliaceum) which are
minor cereals of the small seeded-grass family (Poaceae) mainly

grown in semi-arid regions [2]. These have amazing nutritional value
and are 3 to 5 times more nutritious than rice and wheat in terms of
protein, minerals, and vitamins. They also have a short growing season
(70–80 days), are well suited to multiple cropping systems under both
irrigated and rainfed conditions, and can survive in unusually infertile
soil [3-5]. Within a short time, they can offer highly desired nutrients
in the form of grain and fodder. They are also known as “famine
reserves” because to their improved capacity under normal storage
circumstances.
Despite all the amazing qualities and capacities of millet farming
systems, the area and production of millets in the country have
been drastically reduced over the past five decades from 1955–56
to 2013–14. Over the past six decades from 1950–51 to 2011–12,
the contribution of millets in total food grain production of the
country declined from 22.17% to 6.94%. Out of many factors for
the declination of millet production in the country, weed infestation
is one of the most important factors. The growth of millets is slow
at first and they are weaker than weeds in crop-weed competition
in the first few weeks of their growth. Weeds compete for different
growth resources, namely, nutrients, soil moisture, light, and space.
with the crop and the competition starts when the growth resources
fall below their combined demand. Due to the slow growth of millets
