Abstract:

Present investigation was carried out at College of Agriculture, Badnapur situated at 19⁰52^’00’’ North latitude and 75⁰44^’00’’ East longitudes at 498 m altitude above mean sea level on clayey soil. Soil was moderate in nitrogen, low in phosphorus and high in potassium. Rainfall received during experimental period was 437 mm with 20 rainy days (70% of normal rainfall) during Kharif 2018.The experiment was conducted in split plot design with two factors viz., intercropping systems (T₁-pigeonpea + soybean (2:4),T₁-pigeonpea + soybean (1:6), T₃- sole pigeonpea and T₄-sole soybean) and four irrigation stages (rainfed treatment (I₁), irrigation at bud initiation (I₂), irrigation at pod development (I₃), irrigation at bud initiation + pod development (I₄)) with 16 treatments combinations. Each experimental unit was repeated three times in various plotsize in gross plot and in net plot with various spacing depending on intercropping system. Sowing was completed on 11^th July 2018. The fertilizer dose of 30:60:30 NPK kg/ha was applied at time of sowing.

The significantly maximum number of pods/plant, weight of pod/plantand seed yield/plant were observed with Pigeonpea + soybean (1:6) ratio. The better performance of pigeonpea + soybean (1:6) may be attributed to its better vegetative growth over pigeonpea + soybean (2:4) and sole pigeonpea, respectively. Amongst intercropping system, pigeonpea + soybean (2:4) recorded maximum pigeonpea equivalent yield (2228 kg/ha), than sole pigeonpea and sole soybean, however, it was at par with pigeonpea + soybean (1:6) for pigeonpea equivalent yield. Amongst irrigation stages, two irrigations at bud initiation + pod development recorded significantly maximum pigeonpea equivalent yield (2412 kg/ha) followed by irrigation at pod development, irrigation at bud initiation and rainfed treatment, respectively. In general, significantly better growth and yield were observed with two irrigations at bud initiation + pod development was observed over rest of the irrigation stages and rainfed treatment.

Amongst interactions of intercropping systems and irrigation stages, interaction of pigeonpea + soybean (1:6) with two irrigations at bud initiation and pod development gave significantly maximum PEY (2412 kg/ha) than rest of the interactions.
