Wheat (Triticum aestivum L.) is the second most important cereal crop after rice in providing food
and nutritional security to the masses in India. It is the most widely cultivated cereal crop which is
the largest contributor with nearly 30% of the world grain production and 50% of the world grain
trade. FAO estimated that the world would require additional 198 million tonnes of wheat by 2050
to accomplish the future demands, for which wheat production need to be increased by 77% in the
developing countries. Regarding the global climate change in the past few decades, the impact of
rising temperature on wheat production is gaining concern worldwide. Heat and drought are the
major abiotic stress limiting the wheat production, which are common in semi-arid and arid
region. Keeping the above problem in view total 80 demonstrations on wheat crop were conducted
at farmer’s field in NICRA village Bharu, Jhunjhunu (Rajasthan) during rabi season 2017-18 to
2020-21 for four consecutive years to assess the effect of TGA (Thio Glycolic Acid) agrochemical
foliar spray on stress management in wheat crop. TGA is the organic compound, often called
Mercapto acetic acid (MAA). It contains both thio and carboxylic acid functional groups. It is used
in salt forms including calcium thioglycolate and sodium thioglycolate. Farming situation is
irrigated and soil is sandy loam in Jhunjhunu district. The sowing of wheat crop was done from
second week to last week of November under irrigated condition. Two foliar spray of TGA
agrochemical (100 ppm) on 15 days interval for two times at first and second fortnight in February
month was done by knapsack /power sprayer. Crop was harvested during first/ second week of
April. The data analyzed revealed that the average gross return and net return was `107636 and
`96495; `59111 and `49043 of foliar spray demonstration and local check, respectively. It could be
concluded that average production (12.11 %) and net profit of wheat crop (20.52%) were
increased by foliar spray of TGA under field conditions. The total cost of TGA agro-chemical
material along with two foliar spray cost was about `500/ha. Hence, two foliar spray of TGA agrochemical
at tillering and milking stage in wheat crop could be added in package of practices and
motivate the farmers for adoption of new techniques for stress management in wheat crop and
getting economic returns.
