Abstract

Background and Objective: In order to evaluate the effect of application of biological and chemical nitrogen fertilizers on the intercropping of Pinto bean and Black mustard, this experiment was conducted. Materials and Methods: The first factor was considered at four levels: No fertilizer, Bio-fertilizers (azotobarvar 1 and barvar 2), bio-fertilizer + 50% Chemical Fertilizers urea (125 kg. ha-1) and Bio-fertilizers + 100% Chemical Fertilizers urea (250 kg. ha-1). The cropping pattern was also classified as the second factor in four levels: pure bean, pure Black mustard, incremental intercropping with a ratio of 50% Black mustard, optimum density of Pinto bean mono-cropping, and an incremental intercropping with optimum density of two species in mono-cropping. Results: Ground cover percentage, leaf chlorophyll index and grain yield in Pinto bean and Black mustard and also the oil yield of Black mustard increased by application of bio-fertilizer + 100% urea fertilizer. The lowest Seed Oil content was obtained from bio-fertilizer + 100% chemical fertilizer treatment. The highest percentage ground cover of Pinto bean and Black mustard (93. 08%) and maximum leaf chlorophyll index of Pinto bean (23. 61) were obtained in incremental intercropping with optimum density of two species in mono-cropping. The highest grain yield of Pinto bean (3269. 92 kg. ha-1) and Black mustard (2066. 65 kg. ha-1) and yield of Black mustard oil (865. 65 kg. ha-1) were obtained in their pure cultivation. Conclusion: Based on the land equivalent ratio and relative value total indices, it was evident that intercropping of Pinto bean and Black mustard was more beneficial than mono-cropping.
