Description A field experiment was conducted during kharif seasons of 2003 to
2005 under rain fed situation of Agricultural Research Station,
Kathalagere by considering different sole and intercropping treatments.
Different statistical and biological techniques were attempted to the data
sets. Replicated Yield data were evaluated using stability analysis, yield
sustainability index and crop performance ratio. The stability analysis
showed that maize-urdbean(1:1) and maize-urdbean(2:2) are stable over
years and can be adapted, maize-urdbean(2:1) is found to be specifically
adapted to favorable environment and sole urdbean is specifically
adapted to unfavorable environments. Yield sustainability index (SYI) is
one of biological index to find out the yield sustainability over years. YSI
values (0.724) observed to be more in paired row ratio of maize with two
rows of urdbean (2:2) compare to other row ratio (0.590 and 0.683 for 1:1
and 2:1) , indicating this row ratio is sustainable for providing high
productivity. Crop performance ratio (CPR) and time corrected crop
performance ratio (CPRT) are also one of the biological indexes to find out
the efficiency of intercropping system. The CPR and CPRT values were
subjected to pooled analysis of variance after testing assumptions of
ANOVA. Paired row of maize with two rows of urdbean (2:2) found to be
having higher CPR (1.905) and CPRT (1.674) values compared to others.
From this study, it could be inferred that intercropping of paired row of
maize with two rows of urdbean is efficient in maize-urdbean based
intercroping system.
