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 (N45 P20), T2-Recommended practice (N60 P20), T3– Recommended practice (N60 P20) + water soluble NPK (19:19:19) spray at tillering and ear head emergence stage @ 1.5 percent. These treatments were replicated nine times during 2015-16 and ten times during 2016-17 and 2017-18 at farmers’ fields. Treatment T3 being statistically at par with Treatment T2 registered higher ear length by the tune of 0.8, 1.0, 1.0 and 1.01 percent during 2015-16, 2016-17, 2017-18 and three year mean basis over treatment T1, respectively. On the three year mean basis the treatment T3 recorded 9.52 and 3.85 per cent higher number of grains per ear over treatment T1 and T2, respectively. On three year mean basis treatment T3 was recorded 23.21 and 18.07 per cent higher grain yield over treatment T1 and T2, respectively and 15.10 and 9.52 per cent higher fodder yield over treatment T1 and T2, respectively. On the three year mean basis treatment T3 (Rs 96794/ha) recorded 21.39 and 16.10 per cent higher gross returns over treatment T1 and T2, respectively. Similarly on the three year mean basis treatment T3 (Rs 61796/ha) recorded 25.10 and 16.88 per cent higher net returns over treatment T1 and T2, respectively. On the three year mean basis treatment T3 (2.76) recorded 4.94 and 01.10 per cent higher B: C ratio over treatment T1 and T2, respectively.
