An experiment was conducted at Agricultural Research Station, BARI, Burirhat, Rangpur during rabi seasons of 2004-05 and 2005-06, respectively. The experimental area was a piece of well drained medium high land with moderately even topography. The area belongs to Tista Floodplain (AEZ-3), having low organic matter (1.23%) and deficient in nitrogen (0.068 NH4 -N(µg/g), phosphorus (12.5 µg/g) and Ca (1.5 Meq/100 g) in comparison with the standard nutrient status. The soil is acidic in nature having PH 4.6 with low O.M(1.21- 1.25%) content. Experiments were conducted in the field of ARS Burirhat, Rangpur during rabi seasons of 2004-05 and 2005-06. Treatments were included - T1 = Sole groundnut, T2 = Sole carrot, T3 = One row of carrot in between two normal rows of groundnut (2G : 1C), T4 = Two rows of carrot in between two normal rows of groundnut (2G : 2C), T5 = Two rows of groundnut alternated with two rows of carrot (2G : 2C) and T6 = Three rows of groundnut alternated with two rows of carrot (3G : 3C). The experiment was laid out in a randomized complete block design with three replications having plot size 3m x 4m. Fertilizers were applied at the rate of 30, 100, 30, 30, and 4 kg/ha of N, P2O5, K2O, S, and Zn, respectively, for groundnut (Sole) and 50, 25, 40, and 10 kg/ha of N, P2O5, K2O and S, respectively, for carrot (Sole); and 30, 100, 30, 30, and 4 kg/ha of N, P2O5, K2O, S, and Zn, respectively, for intercropping plots in the form of urea, triple super phosphate, muriate of potash, gypsum, and boric acid. All the fertilizers were incorporated in the soil at the time of final land preparation for sole groundnut plots. But all the fertilizers and one third of urea were applied during final land preparation and remaining two thirds of the urea was top dressed in the sole carrot and intercropped plots in two installments at 25 and 45 DAE. The groundnut variety BARI Chinabadam-6 and carrot variety Pusha Kashore were used for the experiment. Seeds @ 110 kg/ha of groundnut and 2.5 kg/ha were sown on 25-11-2004 and 20-11-2005, respectively. Spacing of sole groundnut and sole carrot were 40 cm x 15 cm and 30 cm x 10 cm, respectively. Two irrigations were applied at 25 and 50 days after emergence (DAE) and other intercultural operations were done as per requirement. At maturity, ten randomly selected plants of carrot and groundnut were uprooted from each plot for post harvest data collection. Data were collected on plant height, number of branches/plant, number of pods/plant, 1000-seed weight, pod yield/plant and pod yield/ha for groundnut; and plant height, root length, root diameter and yield for carrot. Crops were harvested as whole plot basis and yields were converted to t/ha. Collected data were statistically analysed separately compared by using Least Significant Difference (LSD) test (Steel & Torrie, 1960) and land equivalent ratio (LER) values were computed from the yield data of the crops (Shaner et al., 1982)
