Effect of sulphydryl bioregulator sprays on yield and economics in lentil (Lens culinaris) under vertisols

A field experiment was carried out during winter (rabi) seasons 2011–12 and 2012–13 at Agricultural Research Station, Ummedganj, Kota to find out the effective sulhpydryl bioregulator for increasing productivity and profitability of lentil (Lens culinaris) under vertisols of south eastern Rajasthan. Foliar spray of thiourea 500 ppm at pod initiation significantly increased the growth, yield attributes, grain yield (1898 kg/ha), net return ( 52269/ha) and B: C ratio (4.26) as compared to no spray. The alternately urea 2% spray at pre flowering + pod initiation had significant effect on growth, yield attributes, grain yield and economics of lentil.
