Sk. Patil et al., INTERCROPPING OF FORAGE COWPEA (VIGNA-UNGUICULATA) WITH GRAIN-SORGHUM(SORGHUM-BICOLOR) UNDER RAIN-FED CONDITION, Indian Journal of Agronomy, 42(4), 1997, pp. 589-591
A field experiment was conducted to study the production potential of
intercropping of forage cowpea [Vigna unguiculuta (L.) Walp.] with gra
in sorghum [Sorghum bicolor (L.) Moench] under rainfed condition, duri
ng the rainy season (kharif) 1992, 1993 and 1994. The paired-row plant
ing of grain sorghum at 30 cm spacing and 60 ctr, spacing within 2 pai
rs intercropped with 2 rows of forage copwea with 100% NPK (100, 60 an
d 60 kg/ha) to sorghum and 75% of recommended dose to intercrop cowpea
(15, 45 and 22.5 kg/ha) was statistically on a par with 100% recommen
ded fertilizer dose to intercrop in producing 45.1 q/ha sorghum grain,
173.8 q/ha dry fodder of sorghum and 178.1 q/ha great forage of cowpe
a with gross monetary returns of Rs 16,000/ha. It indicated saving of
NPK fertilizers up to 25% of the recommended dose of the intercrop (i.
e. saving of 5, 15 and 7.5 kg N, P and K/ha).
