Description Investigations on “Abiotic and biotic stress management in rainfed chickpea”
were carried out during rabi season of 2005-06 and 2006-07 at Agricultural Research
Station, Gangavathi, UAS, Dharwad, Karnataka.
Interaction of FYM cured DAP and seed priming with 2% SSP (P5S3)
recorded highest grain yield of 1705 kg/ha which was significantly superior and was
on par with interactions P1S2, P1S3, P1S5, P1S6, P2S2, P2S3, P5S1, P5S3, P5S4, P5S5 and
P5S6. While, lowest grain yield of 1096 kg/ha was obtained from combination
involving P application in the form of FYM and without seed treatment. Similarly,
increased number of pods per plant at 60 DAS (29.7) and at harvest (37.7), grain
weight per plant (16.09g) and test weight (9.02g) was recorded with application of
recommended dose of phosphorus through FYM cured DAP and seed priming with
2% SSP. Higher uptake of total nitrogen (102.8 kg/ha), phosphorus (9.0 kg/ha) and
potash (102.7 kg/ha) was recorded with interaction of FYM cured DAP and seed
priming with 2% SSP compared to other interactions except P1S2 P1S3, P1S6, P2S2 and
P2S6. Interaction of FYM cured DAP and seed priming with 2% SSP recorded higher
gross income (37517 Rs/ha), net income (29588 Rs/ha) and B:C ratio (3.73) over
other interactions.
Significantly higher chickpea equivalent yield (CEY) was recorded in
chickpea + sunflower intercropping (T2, 1436 kg/ha). While, lowest CEY was
observed in chickpea + wheat intercropping (T7). Higher number of pods per plant at
60 DAS (T9, 24.6) and at harvest (T9, 34.1) was recorded in sole chickpea. While,
lowest number of pods per plant was recorded in chickpea + wheat (T7) intercropping.
Similarly, grain weight (T9, 7.56 g/plant) and test weight (T9, 15.4 g) were also
significantly superior in sole chickpea than other intercropping systems.
The population of Helicoverpa larvae was reduced as the stage of crop
advanced. Significantly lower number of larvae was observed in chickpea + sunflower
intercropping system. Similarly, the population of spiders and coccinellids were
higher in chickpea + sunflower intercropping system compared to sole chickpea.
Higher gross return (Rs. 30458 per ha), net returns (Rs. 23117 per ha.) and B:C ratio
(4.14) were recorded in chickpea + sunflower intercropping system. While, the lowest
gross return of Rs. 15452 per ha, net income of Rs. 8111 per ha and B:C ratio of 2.1
were recorded in chickpea + wheat intercropping system.
