| dc.description.abstract | Field experiment was conducted during kharif seasons of 2005 -07 under rainfed situation of ARS Kathalagere by considering different sole and intercropping treatments of maize and urdbean. Different statistical and biological techniques were applied to the three data sets. Response surface methodology has been carried out on the yields of converted maize, converted urdbean, actual maize and actual urdbean. Different polynomial models were fitted to identify the optimum row-ratio. In all four cases quadratic polynomial model was found to the best. Paired row of maize with two rows of urdbean system was observed to be most responsive. Area*Time Equivalent Ratio is one of the biological index to find out the efficiency of intercropping system. ATER values calculated for the data sets were subjected to pooled analysis of variance after testing assumption of ANOVA. Significant difference between row-ratio of ATER values observed. Paired row ratio of maize with two rows of urdbean(2:2) noticed higher ATER values. Aggresivity-index is also one of the important biological index to find out competitiveness of one crop over other crop. Calculated aggressivity values were subjected to pooled analysis of variance as done in ATER, result indicated there is significant difference between row-ratio. 2:1 has recorded lower aggressivity value compare to 2:2, however slightly increase in yield realized in 2:2. This may be due to wide row spacing in 2:2. From this study, it could be inferred that intercropping of paired row of maize with two rows of urdbean is efficient in maize-urd based intercroping system. | en_US |
