Abstract:

An experiment on sesame intercropping system was conducted during kharif (rainy) season of 2017 on sandy loam soil (8.72 pH, 0.88 EC dS m^-1), with low nitrogen (137 kg N ha^-1), medium phosphorus (14.4 kg ha^-1) and high potassium content (357 kg ha^-1) at Agricultural Research Station, Mandor, Jodhpur in randomized block design with 3 replications. Among 7 treatments (T1 – Sole sesame, T2 – Sesame + Urdbean in 3:1, T3 – Sesame + Urdbean in 4:2, T4 – Sesame + Mungbean in 3:1, T5 – Sesame + Mungbean in 4:2, T6 – Sesame + Mothbean in 3:1, T7 – Sesame + Mothbean in 4:2 row ratio), it was found that intercropping of sesame with mungbean in ratio 3:1 resulted significantly higher total productivity and net returns (541 kg ha^-1 & Rs. 18270 ha^-1) over sole sesame crop (344 kg ha^-1 & Rs. 6156 ha^-1) followed by mungbean in 4:2 (490 kg ha^-1 with net return of Rs. 15164 ha^-1) being at par with urdbean in 3:1 (473 kg ha^-1 with net return of Rs. 14078 ha^-1). It was concluded that mungbean can be grown as a beneficial intercrop in sesame under dryland conditions of Rajasthan.
