Description Field experiments were conducted to find out suitable row proportion and nutrient
management in pigeonpea and ashwagandha intercropping system at Agricultural College
Farm, Raichur during kharif season of 2005 and 2006 under rainfed condition. The
experiments were conducted on medium black clay loam soil with a pH of 8.2. The
experiments were laid out in randomised block design.
In the experiment on effect of row proportions, the sole pigeonpea recorded
significantly higher seed yield (15.80 q ha-1) than the average yield obtained by intercropped
pigeonpea under various row proportions (12.67 q ha-1). Among various row proportions
studied, the seed yield produced under 2:4 (14.04 q ha-1) and 1:2 (13.95 q ha-1) was
significantly higher than 2:1 (11.34 q ha-1). With respect to ashwagandha, the dry root yield
realised under sole ashwagandha (437 kg ha-1) was significantly higher than the average yield
of intercropped ashwagandha under various row proportions (313 kg ha-1). Among different
row proportions, 1:4 (373 kg ha-1), 1:3 (360 kg ha-1) and 2:4 (354 kg ha-1) recorded on par dry
root yield of ashwagandha and were significantly superior over 2:1 (244 kg ha-1).
Significantly higher net returns (Rs. 33,520 ha-1) and B:C ratio (3.05) was obtained under 2:4
row proportion when compared to 2:1 (Rs.22, 403 ha-1 and 2.47, respectively).
Another study was focussed on nutrient management in companion cropping of
pigeonpea and ashwagandha. The results revealed that among various intercropped fertilized
treatments, the seed yield of pigeonpea (12.84 q ha-1) obtained with the treatment receiving
recommended FYM and 125 per cent RDF to pigeonpea rows (T5) was significantly higher
than that which received the entire P through FYM and N through inorganics (T7) (10.27 q
ha-1). Among the various intercropped fertilized ashwagandha, T6 (recommended FYM and
RDF to pigeonpea and RDF to ashwagandha) recorded significantly higher dry root yield
(369 kg ha-1) than that which received RDF through FYM and entire N through inorganics
(T7) (232 kg ha-1). Significantly higher net returns (Rs. 32,219 ha-1) and B:C ratio (3.01) was
recorded under T6 when compared to T7 (Rs. 18,111 ha-1 and 2.08, respectively).
