Abstract:
The experiment was carried out at the Teaching and Research Farm Delta State University, Abraka. To evaluate the effects of organic and inorganic fertilizer on okra-pumpkin intercrop. The fertilizer treatments were 150kg/ha NPK: 15:15:15, 10t/ha 50%CM+50%CP, 15t/ha 60%CM+40%CP, 20t/ha 70%CM+30%CP, 30t/ha 80%CM+20%CP manure and control. A spacing of 60 cm x 40 cm for okra and 1m x1m for pumpkin plant/ha. The experiment was a 6x3 factorial in a randomized complete block design (RCBD) with three replications. Each plot measured 3.5 m x 3.5 m and 0.5m pathway between plots and 1m between blocks. An improve okra cultivar (Cv-N35) and pumpkin seeds were planted in April 2023 for early planting season and July 2023 for late planting season. Data were randomly collected for growth parameters such as plant height, number of leaves, leaf area, leaf area index, stem girth, vine girth, vine length, pod yield, yield leaf and weights respectively. Data collected were subjected to analysis of variance using SAS (1996), means were separated using Ducan Multiple Range Test (DMRT) at 5% level of probability. Results from study indicated that 30t/ha 80%CM+20%CP were significantly better in growth parameters compared to other treatment except in number of leaves. Based on the findings of this study, it is recommended that subsistence/commercial farmers apply 30t/ha 80%CM+20%CP for increased growth and yield of okra/pumpkin at reduced cost of production.
