The present study was carried out at farmers’ fields of Dausa district of Rajasthan during three consecutive years i.e. Rabi 2015-16, 2016-17 and 2017-18 which falls in Agroclimatic zone IIIa (Semi arid eastern plain zone). The soils of the experimental fields were sandy loam in texture, alkaline in reaction (pH 8.9-9.1), low in organic matter (0.12 -0.23), and nitrogen content and medium to high in potassium content. The study consists three treatments namely T1- Farmers practice (N120 P35), T2- Recommended practice (N90 P20), T3- Recommended practice (N90 P20) + water soluble NPK (19:19:19) spray at tillering and ear head emergence stage @ 1.5 percent. These treatments were replicated seven times during 2015-16 and ten times during 2016-17 and 2017-18 at farmers’ fields. Treatment T3 registered higher effective tillers per meter row length by the tune of 3.68, 5.40, 5.53 and 3.59 percent during 2015-16, 2016-17, 2017-18 and three years mean basis over treatment T1, respectively. On the three years mean basis the treatment T3 recorded 10.54 and 6.86 percent higher number of grains per ear over treatment T1 and T2, respectively. On three years mean basis treatment T3 was recorded 11.63 and 13.84 percent higher grain yield over treatment T1 and T2, respectively and 9.42 and 11.62 percent higher fodder yield over treatment T1 and T2, respectively. On the three years mean basis treatment T3 (Rs 109302/ha) recorded 11.01 and 13.25 percent higher gross returns over treatment T1 and T2, respectively. Similarly, on the three years mean basis treatment T3 (Rs 63487/ha) recorded 12.92 and 15.02 percent higher net returns over treatment T1 and T2, respectively. On the three years mean basis treatment T3 (2.41) recorded 2.55 and 2.12 percent higher B: C ratio over treatment T1 and T2, respectively.
