Effect of Micronutrients in Presence of Different Levels of Organic Manure on Growth and Yield of Tomato (Solanum lycopersicum L.)

Abstract

A field experiment was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka from October, 2017 to March, 2018 to study the effect of micronutrients in presence of different level of organic manure on growth and yield of tomato. There were four combinations of micronutrients viz. N 0 =0 kg Zn 0 kg B/ha, N 1 = Zn 2 kg B 1.5 kg/ha, N 2 =Zn 4 kg B 2 kg/ha, N 3 =Zn 6 kg B 2.5 kg/ha and four organic manure viz M 0 =0 ton/ha, M 1 =Cowdung (15 ton/ha), M 2 =Poultry manure (10 ton/ha), M 3 =(Cowdung 7.5 ton/ha+ Poultry manure 5 ton/ha). The Afsun et al.; AJAHR, 4(2): 1-13, 2019; Article no.AJAHR.50434 2 experiment was laid out in a Randomized Complete Block Design with 3 replications and there were altogether 48 plots. Application of micronutrients and organic manure significantly influenced the growth, yield and size of the tomato. The highest yield (66.96 t/ha) was found from treatments N 2 and the lowest yield (25.69 t/ha) was obtained from treatment N 0 . Due to the application of organic manure, the highest yield (50.78 t/ha) was obtained from M 3 and the lowest yield (39.86 t/ha) was recorded from M 0 . In the case of combined effect, the highest yield (76.33 t/ha) was found from treatment N 2 M 3 and the lowest yield (24.60 t/ha) was found from treatment N 0 M 0 . So, the application of Zn 4 kg B 2 kg/ha along with Cowdung 7.5 ton+Poultry manure 5 ton/ha was the best for growth and yield of tomato. Economic analysis raveled that N 2 M 3 gave the maximum benefit-cost ratio (3.2). So, the application of Zn 4 kg B 2 kg/ha along with Cowdung 7.5 ton+Poultry manure 5 ton/ha was the best for growth and yield of tomato. Original Research Article

Effects of Earthing up and Pruning Systems on Growth and Yield of Tomato (Solanum lycopersicon.)

“…Tripathy and Bastia [25] found that the sesame plant had better growth as a result of higher nutrients availability and uptake due to proper root development. Afsun et al [26] also observed in their study on the effect of micronutrients in presence of different levels of organic manure on growth and yield of tomato that nutrient uptake whether organic or inorganic increase plant growth and development. In tomato production, therefore, earthing up is key in promoting proper tomato root development which enhance efficient nutrient uptake ultimately increasing growth.…”
