A study was carried for treated and untreated silt application at four centers namely Nalgonda (Telangana),
Warangal, (Telangana) Anantapur (Andhra Pradesh) and Kolar (Karnataka) under farmers participatory action research programme (FPARP) conducted in 2008-09 and 2009-10. The data were collected from these centers and analyzed. The
results showed that the contribution of silt application during second year (2009-10) was more pronounced although 2009 was
a mega drought year. Rainwater productivity in terms of yields without and with silt application during 2009-10 (2
year)
varied from 0.29 and 0.33 kg/ha/mm in case of mulberry in Kolar to 2.07 and 3.34 kg/ha/mm in groundnut in Anantapur,
respectively. Significantly higher yield increase in treated with silt over untreated registered in case of castor (229% or 2.52 q/
ha) in Nalgonda and groundnut (153% or 4.07 q/ha) in Anantapur while it was non-significant in case of cotton in Warangal
and mulberry in Kolar during 2008-09. Across the crops and between the treated versus untreated trials and years, cotton in
Warangal district registered the highest benefit-cost ratio in treated (3.75) and untreated (3.14) trials. Water productivity of
crops in terms of income accrued per millimeter of water was found to be higher with silt application than without in both the
years in all the centers, however, year 2009-10 was better than 2008-09. The additional benefits to cost ratio (BCR) ranged
between 5.16 in case of cotton in Warangal and 0.25 in case of mulberry in Kolar. The pay back period (PBP) and BCR at
12% discount rate of silt application in castor cultivation was found to be 6 years and 1.70, respectively while internal rate of
return (IRR) worked out to 30%.
