Abstract
Field experiments were conducted at Agricultural Research Station, Devihosur
in black clayey soil under rainfed condition during 2004-06. The experiments were
laid out in split plot design. The treatments comprised of two chilli genotypes (cv.
Byadagi kaddi and Hy. 9646) with Jayadhar cotton as mixed crop (main plot) and six
intercrops viz., soybean, french bean, coriander (vegetable), coriander (seeds), garlic
and onion (sub-plot).
Significantly higher dry chilli yield was recorded with genotype Hy. 9646
(1013 and 355 kg/ha) compared to cv. Byadagi (737 and 293 kg/ha) under both
conventional and organic system of cultivation, respectively. Intercropping coriander
(vegetable) with chilli + cotton recorded significantly higher dry chilli yield (1122 and
504 kg/ha) in conventional and organic cultivation systems, respectively.
Intercropping coriander (vegetable) with chilli + cotton recorded significantly higher
kapas yield (580 and 629 kg/ha) in conventional and organic cultivation, respectively.
Chilli equivalent yield was highest with chilli cv. Byadagi (2189 and 1400 kg/ha)
compared to chilli genotype Hy. 9646 (2096 and 1327 kg/ha) due to inclusion of chilli
genotypes in intercropping with chilli + cotton in both conventional and organic
system of cultivations, respectively. Intercropping garlic with chilli + cotton based
cropping system recorded significantly higher chilli equivalent yield (3216 and 2443
kg/ha) compared to rest of the treatments in both conventional and organic system of
cultivation. Inclusion of chilli cv. Byadagi with intercropping chilli + cotton mixed
cropping system recorded significantly higher B:C ratio (2.6 and 0.69) compared to
chilli genotype Hy. 9646 (2.16 and 0.44) under both conventional and organic form of
cultivation. Intercropping onion with chilli + cotton accounted for significantly higher
B:C ratio (3.41) in conventional cultivation while intercropping garlic with chilli +
cotton recorded highest B:C ratio (1.22) under organic form of cultivation.
Intercropping onion with chilli (cv. Byadagi) + cotton recorded significantly higher
B:C ratio in conventional cultivation and intercropping garlic with chilli (cv. Byadagi)
+ cotton under organic form of cultivation.
