An experiment was conducted during Kharif, 2016 and 2017 at the Regional Research and Technology Transfer Station, Bhawanipatna to find out suitable eco-friendly management practices of pod borer complex in pigeon pea. The trial was laid out in randomized block design with three replications taking thirteen treatments. Experimental results showed that the lowest mean population of spotted pod borer larvae (0.02/plant) was recorded in the treatment Bt @ 1 kg/ha + Flubendiamide 480 SC @ 200 ml/ha followed by Ozoneem @ 1.5 lit./ha + Flubendiamide 480 SC @ 200 ml/ha with 0.06/plant and Bt @ 1 kg/ha + Spinosad 45 SC @ 200 ml/ha with 0.07/plant as compared to the control (3.03/plant). Two times spraying of Ozoneem @ 1.5 lit./ha + Flubendiamide 480 SC @ 200 ml/ha recorded the lowest mean larval population (0.02/plant) of H. armigera followed by Bt @ 1 kg/ha + Flubendiamide 480 SC @ 200 ml/ha with 0.04/plant, Bt @ 1 kg/ha + Spinosad 45 SC @ 200 ml/ha with 0.07/plant and Bt @ 1 kg/ha + Emamectin Benzoate 5 SG @ 200 g/ha with 0.09/plant compared to the untreated control (3.22 larvae/plant). Lowest spiny pod borer population was reported in Bt @ 1 kg/ha + Flubendiamide 480 SC @ 200 ml/ha and Bt @ 1 kg/ha + Spinosad 45 SC @ 200 ml/ha (0.02 larvae/plant) compared to control (1.50 larvae/plant). Highest grain yield (14.6 q/ha) was recorded in Bt @ 1 kg/ha + Flubendiamide 480 SC @ 200 ml/ha followed by Ozoneem @ 1.5 lit./ha + Flubendiamide 480 SC @ 200 ml/ha with 14.2 q/ha. Bt @ 1 kg/ha + Flubendiamide 480 SC @ 200 ml/ha recorded the highest B: C ratio (2.19) followed by Ozoneem @ 1.5 lit./ha + Flubendiamide 480 SC @ 200 ml/ha (2.17).
An experiment was conducted to study the effect of integrated nutrient management in scented rice and its residual effect on pea under paira cropping system at Regional Research and Technology Transfer Station (RRTTS), Bhawanipatna, Kalahandi, Odisha during 2015-16 and 2016-17. Twelve treatment combinations comprising of T1 - FYM @ 10 t ha-1 + vermicompost @ 2.5 t ha-1 + neem cake @ 2.5 q ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T2 - STBFR (Soil test based fertilizer recommendation 75 : 30 : 20 kg N:P2O5: K2O ha-1), T3 - STBFR + FYM @ 5 t ha-1, T4 - STBFR + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T5 - STBFR + Zn @ 5 kg ha-1, T6- STBFR + S @ 20 kg ha-1, T7- STBFR + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T8- STBFR + FYM @ 5 t /ha + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T9 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1, T10 - STBFR + FYM @ 5 t ha-1 + Azospirillum @ 5kg ha-1+ PSM @ 5kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1, T11 - Farmers practice (only chemical fertilizer @ 40 : 20 : 20 kg N : P2O5 : K2O ha-1), T12 - STBFR + vermicompost @ 2.5 t ha-1 were tried in RBD with three replications. The soil of the experimental site was black cotton type having pH- 6.11 , O.C.- 0.72 %, E.C- 0.004 (dS m-1), available N -175.9 kg ha-1 (low), available P-36.7 kg ha-1 (medium) and available K- 283.6 kg ha-1 (high). Geetanjali was the test variety for rice and Azad Pea-1 for pea. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) to medium duration aromatic rice (var. Geetanjali) produced higher rice grain yield (4065 kg ha-1) and pea seed yield (1044 kg ha-1) from aromatic rice -pea paira cropping system. However, application of STBFR + FYM @ 5 t ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 producing grain yield (3944 kg ha-1) and pea seed yield 977 kg ha-1 is another option. Application of STBFR (75 : 30 : 20 kg N : P2O5 : K2O ha-1) + FYM @ 5 t ha-1 + Azospirillum @ 5 kg ha-1 + PSM @ 5 kg ha-1 + Zn @ 5 kg ha-1 + S @ 20 kg ha-1 (T10) recorded maximum gross return (Rs. 1,26,991 ha-1) , net return (Rs. 80,146 ha-1) and B : C ratio of 2.71. The increase in rice equivalent yield (REY) in this treatment was 51.4% higher than the farmer practice i,e., application of chemical fertilizers alone (40 : 20 : 20 kg N : P2O5 : K2O ha-1).
