A field study was conducted to study the effect of sulphydryl bio-regulator like thiourea through foliar application on growth, yield and profitability of lentil in rice fallows. The experiment was laid out in randomized block design and replicated thrice with thirteen treatments including water spray (control), 2% urea, 500ppm and 1000ppm thiourea at different stages of crop growth. Results revealed that application of thiourea @ 1000ppm at pre-flowering and pod initiation recorded significantly increased shoot length (34.1cm), total dry matter (19.52 g plant-1), number of pods plant-1 (73.8) and thereby enhanced grain yield (15.9 q ha-1), straw yield (33.0 q ha-1) and protein yield (325.4 kg ha-1) followed by recorded higher total nitrogen (106.78 kg ha-1), phosphorus (24.06 kg ha-1), potassium (63.48 kg ha-1) and sulphur (6.74 mg kg soil-1) uptake. Moreover, this method of providing growth promoters and nutrients directly to metabolic sites (leaves) at critical stages fetched higher net returns (Rs. 53055 ha-1) and yielded B: C ratio (2.95) over other treatments and control. The mean seed yield (74.4%) in the above treatment was significantly higher compared to the control (no spray) and low dose of spray (500 ppm). Hence, foliar application of thiourea at 1000ppm at pre flowering and pod initiation is promising and profitable for economical lentil production by resource poor farmers of NEH Region.
