Abstract/ Executive Summary:

Pot experiment supported by a laboratory analysis was conducted to evaluate the performance of bio-slurry on tomato production during November 2011 to April 2012. The experiment was laid out in a Complete Randomized Design (CRD) with 3 replications. There were 6 treatments viz., T₀ - Control, T₁- Recommended fertilizer Dose (RFD), T₂ – 60% RFD + Poultry Manure (PM), T₃ - 60% RFD + Poultry slurry, T₄ - 60% RFD + Cow-dung (CD), T₅ - 60% RFD + Cow-dung slurry. Chemical analysis of cow-dung, cow-dung slurry, poultry manure and poultry manure slurry showed that the Organic matter, Organic carbon, N, P, K and S varied from 32-69.5, 18.6-40.4, 1.51- 2.94, 0.51- 0.81, 0.45- 1.36, 0.39- 0.46%, respectively. Cow-dung and cow-dung slurry had the higher Organic matter and Organic carbon content while poultry manure and poultry manure slurry had the higher nutrient concentration. Nutrient concentration particularly N and K in cow-dung and poultry bio-slurry was found to be lower than the cow-dung and poultry manure. The growth and yield of tomato were significantly influenced by the application of different manure at 1% level of probability. The tallest (58.40cm) plant was observed in T₂ while the shortest plant (17.10cm) was found in T₀ treatment. The highest number of fruits plant^-1 (16.33) was produced in T₁ and it was lowest (4.33) in T₀. The highest average fruit weight (33.55 g fruit^-1) was observed in treatment T₃ and the lowest was in T₀ (19.84 g fruit^-1). The highest yield (516.57 g pot^-1) was recorded in T₃ followed by T₁ (465.39 g pot^-1), T₂ (450.01 g pot^-1), T₄ (410.80 g pot^-1), T5 (376.27 g pot^-1) and the lowest (85.4 g pot^-1) in T₀. The yield of tomato was increased by 445, 427, 505, 381 and 340 % over control in T₁, T₂, T₃, T₄ and T₅ respectively. Application of poultry bio-slurry in combination with chemical fertilizer showed the best performance on tomato yield. The use of poultry bio-slurry not only gives higher yield but also improves soil health which is necessary for sustainable crop production by maintaining soil fertility and productivity.

End Date: 00-04-2012

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

1. To study the nutrient concentration in different manure and bio slurry and to observe the effect of different manure and bio slurry on tomato production.

Methodology:

The pot experiment was conducted in the open net house of the Soil Science department, Bangladesh Agricultural University, Mymensingh during the period from November, 2011 to April, 2012 to evaluate the effects of bio-slurry on tomato (cv. Ruma VF) production. There were 6 treatments viz., T₀ - Control, T₁ - Recommended fertilizer Dose (RFD), T₂ – 60% RFD + Poultry Manure (PM), T₃ - 60% RFD + Poultry slurry, T₄ - 60% RFD + Cow-dung (CD), T₅ - 60% RFD + Cow-dung slurry. The experiment was laid out in a Complete Randomized Design (CRD) with 3 replications. There were 18 (6×3) unit plastic pots having the diameter of 35cm and depth of 30 cm. The soil used in this experiment was collected from a selected area of Soil Science field of Bangladesh Agricultural University, Mymensingh. Poultry manure and poultry slurry were collected from Krishibid Poultry Farm, Valuka, Mymensingh and cow-dung and cow-dung slurry were collected from dairy farm of Bangladesh Agricultural University. chemical composition (e.g organic matter, organic carbon, N, P, K and S) of samples were analyzed in the laboratory to study their manural value before application to soil. The doses of cow-dung, poultry manure, slurry and chemical fertilizers were applied as per the treatments. Cow-dung, poultry manure, slurry and recommended doses of TSP and MOP were mixed thoroughly with soil. Urea was applied in three installments, one third at the final land preparation and the rest two thirds were applied at 30 days intervals after transplanting. Intercultural operations were performed as and when necessary throughout the growing period of the crop. Fruits were harvested at full maturity at several times. Data on Plant height, number of fruits per plant, weight of fruit and yield were collected. Data were analyzed for ANOVA with the help of a computer package program of MSTAT-C. A one way ANOVA was made by F variance test. The pair comparisons were performed by Least Significant Difference (LSD) test at 1% level of probability.

Achievement/Findings:

The growth and yield of tomato were significantly influenced by the application of different manure at 1% level of probability. The tallest (58.40cm) plant was observed in T₂ while the shortest plant (17.10cm) was found in T₀ treatment.
