Abstract: The field experiment on cotton based pulse intercropping on vertisol was conducted during to study the nutrient availability and crop yield. Treatments comprised of sole cropping of cotton, green gram and black gram, intercropping of cotton with green gram and black gram with 1:1 and 1:2 row ratios. The available nutrients in soil were estimated at sowing, at harvest of intercrops and cotton while, micronutrients (Fe, Mn, Zn and Cu) were estimated after completion of all cropping systems. Organic carbon and available N, P and K contents were found to be maximum at harvest of intercrop stage and then decreased at harvest of cotton, although, the values are higher than at sowing stage. Significantly maximum organic C (5.89 g kg-1) and available N (225.18 kg ha-1) were noted under sole green gram followed by sole black gram at harvest. Intercropping recorded the higher contents over sole cotton. At harvest of cotton, the higher organic C (5.49 g kg-1) and available N (192.31 kg ha-1) were recorded in cotton + green gram (1:2) row proportion followed by cotton + black gram (1:2). However, at the end of cropping systems, the maximum available P (22.53 kg ha-1) and available K (384.36 kg ha-1) were noticed under cotton + green gram (1:1) followed by cotton + black gram (1:1) intercropping as compared to sole cotton. Micronutrients were estimated after completion of each cropping system and significantly the highest contents of Fe, Mn, Zn and Cu (7.96, 20.28, 4.06 and 4.80 mg kg-1, respectively) were observed under cotton + green gram (1:2) and the lowest were noted under sole cotton cropping. The highest seed cotton yield (2496.56 kg ha-1) and stalk yield (7340.58 kg ha-1) was produced under sole cotton. Among cotton based pulse intercropping, the higher cotton yield was noticed with 1:1 row proportion as compared to 1:2. However, the maximum seed and straw yield of green gram (1063.25 and 1493.05 kg ha-1) and black gram (934.70 and 1274.21 kg ha-1) were produced under sole cropping. In intercropping with cotton having 1:2 row proportion produced higher yields of green gram and black gram over 1:1 row proportion.
