12. Effects of organic substrates and effective microorganisms (EM) on growth and yield of tomato (Lycopersicon esculentum Mill.) in greenhouse condition

Abstract

Conventionally farmers are employing farmyard manure to increase the tomato yield. Leaf compost and poultry manure are microbial decomposed organic media that have rich source of nutrients, optimal water holding capacity and good circulation of air. However, farmers are still not satisfying with their results to increase the tomato production. This difficulty enforced to add and test additional supplements for increasing the performance of available organic substrates. To address these issues an experiment was carried out at Institute of Hydroponic Agriculture in Controlled Environment Greenhouse Conditions for testing of effective microorganisms (EM) with different mixtures of substrates. Four treatments of experiments were made with different mixtures of organic substrate and effective microorganism viz., T₁ poultry manure control (PM), T₂ poultry manure + effective microorganism (PM+EM), T₃ leaf compost control (LC) and T₄ leaf compost + effective microorganism (LC+EM). The quantity of EM was 80 ml for each plastic bag. The collected data were statistically analyzed by using complete randomized design (CRD) at 5% level of probability with statistix 8.1 software. The statistical analysis showed that Treatment T₂ poultry manure + effective microorganism (PM+EM) performed better results as compared to other treatments. Experimental results suggests to practice the effective microorganism with poultry manure.
