dc.description.abstractA field experiment was conducted in the experimental field, All India Coordinated Research project on Dryland Agriculture, Biswanath Chariali centre, Biswanath college of Agriculture, Assam Agricultural University during the rabi season of 2020-21 to study the “Performance of Rajmah based intercropping system under rainfed situation”. The soil of the experimental site was sandy loam in texture, acidic in reaction (pH 4.98), medium in organic carbon (5.80 g kg-1), available N (330.10 kg ha-1), available K2O (171.35kg ha-1) and available P2O5 (23.26 kg ha-1). The experiment was laid out in Randomized Block Design (RBD) involving three (3) replications with thirteen (13) treatments consisting of five (5) crops (rajmah, toria, linseed, lentil and buckwheat) which were grown solely as well as intercropped in different ratios of 1:1 and 2:1 viz. T1: sole rajmah, T2: sole toria, T3: sole linseed, T4: sole lentil, T5: sole buckwheat, T6: rajmah + toria (1:1), T7: rajmah + linseed (1:1), T8: rajmah + lentil (1:1), T9: rajmah + buckwheat (1:1 ), T10: rajmah + toria (2:1), T11-rajmah + linseed (2:1), T12: rajmah + lentil (2:1) and T13: rajmah + buckwheat (2:1). The competitive behavior of component crops in different intercropping system was determined in terms of land equivalent ratio (LER), relative crowding coefficient (RCC), aggressivity (A) and monetary advantage index (MAI). The results revealed that rajmah+lentil (2:1) intercropping system (T12) was found to be more economical and highest monetary advantage index (6012.08). The same system had the highest aggressivity value (+1.19 & -1.19 respectively) followed by rajmah + linseed (2:1). The relative crowding coefficient was >1 in rajmah among the intercropping treatments indicating yield advantage compared with sole cropping except T6, T9, T10 and T13 treatments. Rajmah intercropped with lentil under 2:1 ratio recorded the highest land equivalent ratio (1.18) and rajmah equivalent yield (13.46 qha-1). Economic analysis of the intercropping system revealed the highest gross return (Rs. 96,912.00 ha-1), net return (Rs. 66,132.00 ha-1) and benefit:cost ratio (3.1) under rajmah + lentil (2:1) ratio.
