Abstract
ARSTRACT An experiment was conducted during 1988-1993 on Vertisols to study sustain:~hiltiy olri~iny-season (kharij) cropping systems under rainfed conditons. Grain yield of pearl millet [Pennrsc/re~r glcrrrc~rn~ (L.) Br. remend. Stuntz] (19.64 qha) incressed owing to intercropping with pigeonpea [CU~U~II,~ (I..) Millsp.] cawt (3.58 qha) compared with sole pearl millet (17 68 qha) showing complimentary ellccts. IDeilrl nlillet yield increased by 17.9% under sunflower (Helianthus annuus L.)-pearl millet system coaipi~wd with continous pearl millet and by 32.8% under sunflower-pearl millet + pigeonpea system compnrcd with sorghum [Sorghum bicolor (L.) Moe~ch]Lpearl millet + pigeonpea system. Significantly highcsl monctilry returns (Rs 9.414ha) were obtained from pearl millet + pigeonpea (2 : I ) intercropping in ulrmnt-ycilr cropping. Similarly, sole pearl millet also gave significantly more monetary returns (Rs 6,98O/ha) than rcst of the sole crops. Sustainable valueindex was the highest (0.62) under pearl millet + pigeonpa (2 : I) intcrcropping, followed by sole pearl millet (SVI 0.50), indicating sustainability of these crops during tlic khctrifseason on nledium deep Vertisols ( 3 W 5 cm) of dryland areas.References

Most of the farmers of dryland areas have kharifciops is to adopt crop rotations. The a tendency of growing winter-season (rabi) productivity of these mediuni deep (30-45) sorghum [Sorghum bicolor (L.) Moench] Vertisols could considerably be increased even on medium deep Vertisol having depth with intercropping of pearl millet + from 30 to 45 cm. However, due to low pigeonpea [Cajanus cujan (L.) Milssp.]. moisture-holding capacity of these coils, This intercropping is also more stable and they could not sustain rabi sorghum under remunerative than sole cropping during receding soil moisture. Therefore, Patil et kharij-season (Umrani, 1 98 1
