| Abstract | Farmers are facing many constraints related with pigeonpea cultivation therefore proper resources management and scientific practices can increase the production and productivity of pigeonpea. Drip and mulching can be a way to achieve the goal of more crop per drop. The field experiments were conducted during kharif season of year 2016–17 and 2017–18. The study area is located (23T 16′48" N-latitude, 77T 21′36" E-longitude) in Madhya Pradesh. The experiment was laid out in vertisols with twenty seven treatment combinations consisting of three mulching, three discharge rate (2 lph-D₁, 4 lph-D₂ and 8 lph-D₃) and three irrigation levels viz. 60% CPE (I₁), 80% CPE (I₂) and 100% CPE (I₃). Well treated bold seeds of pigeonpea (TJT-501) were dibbed in soil on ridge-furrow land configuration. The plant height was maximum in 2 lph (175.78 cm), I₂ (176.10 cm) and number of branches, number of pods per plant, seeds per pod also followed the same trend. Maximum yield was registered with D₁ (16.48 q/ha) followed by D₂ (14.91 q/ha) and D₃ (14.46q/ha). Irrigation level I₂ (16.01 q/ha) registered 13.77% higher seed yield than I₁ (14.07 q/ha). In case of discharge rate, B:C decreased as rate increased. Among irrigation level treatments, lowest value (1.26) of B:C recorded with 60% CPE whereas highest B:C (1.56) was registered with 80% CPE, which is at par with 100% CPE (1.52). It can be concluded that pigeonpea cultivation is not economical with mulch and 100% supply of irrigation during kharif. It is viable to supply irrigation as per CPE only at branching, flowering and pod development stages. |
