Abstract/ Executive Summary:

An experiment was conducted to evaluate the effect of cowdung and poultry litter on the growth and yield of okra. The two factors experiment was laid out in Randomized Complete Block Design (RCBD). The highest level of poultry litter (11 t/ha) gave the best result on plant height (61.73 cm.), number of leaves (16.54), leaf length (17.14 cm.), leaf breadth (22.13cm.), green pod yield/plot (2.62 kg), pod yield/ha (7.30 ton) and the lowest green pod yield/pot (2.18 kg), pod yield/ha (6.18 ton) were produced from control treatment. The combined effect of various level of cowdung and poultry litter also found significant. The maximum cowdung and poultry litter (9 t/ha and 11 t/ha) showed the best performance on pod yield/plot (3.24 kg), pod yield/ha (9 ton) and the lowest green pod yield/pot (1.80 kg), pod yield/ha (5 ton) were produced from control treatment.

Objectives:

To evaluate the effect of cowdung and poultry litter on the growth and yield of okra.

Methodology:

The okra variety used in the experiment was "BARI Dherosh 1" which is resistant to yellow vein mosaic virus, a severe disease of okra. This is a high yielding variety developed by the Vegetable Division of Horticulture Research Center, Bangladesh Agricultural Research Institute (BARI). The field experiment was conducted by Randomized Complete Block Design (RCBD) with three replication. The whole field was divided into three blocks and each block consisted of 16 plots. Thus the total numbers of plot were 48. The size of unit plot was 3.6m² (3m×1.2m). A distance of 0.5 m between the plots an d 1.0 m between the blocks were kept. The treatment w as randomly assigned to each of the block. Each unit p lot had 2 rows and each with 6 plants. Plant to plant distance was 50 cm and row to row distance was 60 cm. Two factors were used in the experiment viz. four levels of cowdung and four levels of poultry litter.

Factor-A: Four levels of cowdung C₀: Control (No cowdung application), C₁: 9 ton/ha (contain 90 kg N, 45 kg P and 99 kg K), C₂: 10 ton /ha (contain 100 kg N, 50 kg P and 110 kg K), C₃: 11 ton /ha (contain 110 kg N, 55 kg P and 121 kg K).

Factor-B: Four levels of Poultry litter P₀: Control (No poultry litter application), P₁: 7 ton /ha (contain 77 kg N, 35 kg P and 91 kg K), P₂: 8 ton /ha (contain 88 kg N, 40 kg P and 104 kg K), P₃: 9 ton /ha (contain 99 kg N, 45 kg P and 117 kg K).

Statistical analysis: The collected data on various parameters were statically analyzed using Statistics 10 package program. The me an for all the treatment was calculated and analysis of variances of all the characters were performed by F-variance test. The significant of difference between the pairs of treatment means was evaluated by the Least Significant Difference (LSD) test at 5% and at 1% levels of probability.

Achievement/Findings:

These results suggested that Cowdung and poultry litter had significant influence on yield of okra and C₃P₃ (11 ton cowdung/ha and 9 ton poultry litter/ha) gave the highest yield. The present study was conducted in an individual soil type and further regional trials should be needed to evaluate other organic manures as source of nutrients for better yield of okra.
