Abstract

Unscrupulous use of synthetic fertilizers are not only increasing cost of tomato production but also decreasing tomato yield and quality, deteriorating soil health and environment. Organic manures can produce quality product as well as maintain soil health. Considering this verity an experiment was carried out at the Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna to evaluate the performance of tomato crop under application of different organic and inorganic fertilizers. The experiment was designed in RCBD using two varieties (BARI Tomato-14 and BARI Tomato-15) and eight treatments [i) 100% Recommended fertilizer dose (RFD) for N, P and K; ii) 100% cowdung (CD); iii) 100% poultry manure (PM); iv) 100% vermi-compost (VC); v) 100% Mustard oil cake (MOC); vi) 100% organic manures (25% of each of CD , PM , VC and MOC); vii) 80% organic manure (20% of each of CD, PM, VC and MOC) + 20% RFD; viii) 60% organic manure (15% of each of CD, PM, VC and MOC) + 40% RFD].The tallest plant (77.5 cm) with maximum fruit length (5.98 cm), maximum number of flower clusters plant-1 (16.24), number of flowers cluster-1 (13.07), number of fruit clusters plant-1 (8.20) and number of fruits cluster-1 (6.97) were observed from combined effect of 60% organic manures with 40% RFD in BARI Tomato-15. On the contrary, this treatment produced maximum fruit diameter (6.29cm), maximum weight of individual fruit (91.43g) and the highest yield (87.17 t/ha) in BARI tomato-14. From economic point of view, maximum net return (Tk. 841345) as well as benefit cost ratio (5.11) was also observed from 60% organic manure + 40% RFD. Thus, BARI tomato-14 with combination of organic manures (60%) and inorganic fertilizers (40%) provided better performance concerning growth, yield and economic aspects.  J Bangladesh Agril Univ 17(4): 500–506, 2019

Highlights

Tomato (Solanum lycopersicum L.) is one of the most important vegetables in the world and in terms of area, it ranks next to potato and sweet potato but ranks first as the processing crop (FAO, 2010)
From the findings of the present study, it may be concluded that integrated application of 60% organic manures and 40% RFD can provide the best results for growth and yield of tomato
This study suggests that the effect of these manures can compensate up to 60% reduction of recommended fertilizers. Both organic and inorganic fertilizers should be used by the farmers for profitable tomato production

Summary

Introduction

Tomato (Solanum lycopersicum L.) is one of the most important vegetables in the world and in terms of area, it ranks next to potato and sweet potato but ranks first as the processing crop (FAO, 2010). It is essential to find out the best productive variety with optimum fertilizer dose for maximum production (Latha et al, 2002) In this regard, synthetic fertilizers are the best way of crop production, but continuous application of chemical fertilizer increases organic matter depletion and damages the chemical and physical properties of soil. Synthetic fertilizers are the best way of crop production, but continuous application of chemical fertilizer increases organic matter depletion and damages the chemical and physical properties of soil Those fertilizers are expensive and sometimes they are not readily available in the market. Many countries are considering organic agriculture as the well-established and certified forms of cropping systems among all the alternative cropping patterns (Adediran et al, 2003)
