Abstract:
Frontline demonstration was formulated to evaluate the Soil Test Based Fertilizer Recommendation in Groundnut at farmers' field level at Nellore district. The FLD was conducted with 30 demonstrations with 30 individual farmers during kharif season, 2018-19 to 2020-21 at Annagaripalem, Nadimpalli, Nagayagunta, Kothavangal villages of Nellore district. Soil Test Based Fertilizer application recorded higher plant growth and yield parameters hence there was a significant increase in yield from 3100 (check) to 3453 kg/ha encountered with treatment Soil Test Based Fertilizer application which was a rise of about 11.38%.in case of soil fertility status. An increase in net returns from Rs. 61,415/- to Rs. 87,126/- was recorded with farmers who followed Soil Test Based Fertilizer Recommendation over the farmers practices. High benefit cost ratio was recorded with Soil Test Based Fertilizer application i.e 2.17 over the existing local variety (1.79). The average technology gap and index were recordedas 797 kg/ha and 18.74 percent, respectively. Because of its judicious use of fertilisers, improved soil fertility status at harvest in the demonstration plot compared to farmer practise (local check) will save fertiliser doses.
