India is the largest producer and consumer of redgram in the world. Redgram also known as
Pigeon pea (Arhar or tur in local language) is an important legume and pulse crop of India and
is being cultivated on 35.50 lakh ha area with a production of 4.43 Million tones in 2021-2022
(ANGRAU Outlook report, 2021). Among total pulses production, redgram accounts for
14.5% in area and 15.5% in productivity. Maharashtra is the largest producer with
approximately 12.47 lakh ha area with average productivity of 11.31 Q/ha. Redgram as a pulse
crop is an important source of protein for human and animal diet and has its own contribution
as a builder and restorer of soil fertility. Redgram contains about 22 percent protein, which is
almost three times that of cereals. Redgram supplies a major share of protein requirement of
vegetarian population of the country. It is particularly rich in lysine, riboflavin, thiamine, niacin
and iron. In Ethiopia, not only the pods, but also the young shoots and leaves are cooked and
eaten. According to the latest Agriculture Census, the total number of operational holdings in
India numbered 138.35 million with an average land size of 1.15 hectares of the total holdings,
85 per cent are in marginal and small farm categories of less than 2 hectares. These small farms,
though operating only on 44 per cent of land under cultivation, are the main providers of food
and nutritional security to the nation but have limited access to resources as well as
technologies. To ensure livelihood security of marginal and small farmers, it is necessary to
focus on their technological needs at lower costs.
Methodology
Crop species is considered as an important parameter. Pigeon pea crop is very well fitting in to
various agro-ecological sub-regions for inter cropping with cereals as well as sole crop. This
crop grains serve for protein supplement for vegetarian human population diet and fodder for
the animals. PRG158 variety red gram, which is widely grown. Another important parameter
that influences the weeding operation is row to row spacing of the crop which requires some
Emerging approaches (RS, AI, ML, Drones etc) for crop management &assessment
