Abstract:
Eucalyptus tereticornis (family – Myrtaceae) is highly use full and important species in commercial forestry due to fast growing and short rotation period. The present investigation was conducted in Eucalyptus tereticornis and wheat based agroforestry system with different weed control methods to find out correlation of wheat yield with various growth characters and weed density under agroforestry system. In experiment plot 5 major weeds Phalaris minor, Rumex dentatus, Chenopodium album, Launaea nudicaulis and Melilotus indica was found with wheat crop. The correlation analysis revealed that Phalaris minor had highest negative association with grain yield (-0.731 and -0.795) during both the year. Regression analysis revealed that the reduction in yield could be to extent of 0.61 q/ha with increase of one plant of Launaea nudicaulis during both year. Rumex dentatus reduced highest extent of grain yield (0.58 q/ha) with add a single plant. The degree of association of different yield association parameter with yield of grain indicate that length of panicles had highest positive correlation (0.992 and 0.982) amongst different production increasing parameter followed by 1000 grain weight (0.993 and 0.980), leaf area index (0.986 and 0.960), number of effective tillers (0.889 and 0.939) and plant height (0.883 and 0.926) during both the year. The yield was increasing predicted with index of leaf area, height of plant, effective tillers, panicles length, and weight of 1000 grain during both the year. The production was increase with 14.36 and 14.25, 0.73 and 0.64, 0.37 and 0.34, 2.60 and 2.42, 0.75 and 0.90 q/ha during both the year under this agroforestry system.
