Effect of Some Organic Fertilizers on Growth, Yield and Quality of Tomato (<i>Solanum lycopersicum</i>)

Abstract

Abstract. In the present study, a field experiment was conducted to study the effect of some organic fertilizers on four varieties of tomato viz., Sadia F1, Isabella F1, Lelord and Sun cherry for its growth, yield and fruits sensory. A total of 64 plots were prepared with the dimension of 3 m 2 x 4 m 2 and each plot was applied with recommended doses of organic fertilizers. The results on the growth parameters of the studied tomato varieties showed that the chicken manure had the significant effect on plant height and root length of Isabella F1, leaf area of sun cherry, root fresh and dry weight and of Lelord, leaves fresh and dry weight of Sadia F1. Whereas, shoot fresh and dry weight of Isabella tomato variety was increased when treated with mixed manure. Agro fish pellet treatment had increased the stem diameter of Isabella F1 significantly. The number of flowers and fruits of sun cherry tomato variety were increased when treated with agro fish pellet. Agro fish also influenced the fruits number in Sadia F1 and fruit yield of lelord followed by Isabella F1 respectively. The sensory evaluation of the fruits of studied tomato varieties revealed that chicken manure had good result on the overall quality of the fruits of Sadia F1 and Sun cherry. Agro fish pellet and mixed manure has influenced the overall quality of Isabella F1 and Lelord variety tomato fruits.

Reposição Deficitária De Água E Adubação Com Organomineral No Crescimento E Produção De Tomateiro Industrial

“…A alta solubilidade dos adubos minerais, principalmente os nitrogenados e potássicos, faz com que permaneçam por pouco tempo na rizosfera, ao passo que os adubos organominerais, por serem constituídos de frações orgânicas de lenta mineralização, permanecem por maiores períodos no sistema, reduzindo perdas por lixiviação e auxiliando na liberação dos nutrientes a planta (MALAQUIAS; SANTOS, 2017). Resultados semelhantes foram encontrados por Kalbani et al (2016), onde a aplicação de resíduos orgânicos contendo estrume + carcaça de frango durante a fase vegetativa favoreceu o crescimento do tomateiro. Rady (2012) observou que a aplicação de fertilizantes organominerais, além de potencializar o crescimento, eleva os níveis de prolina, clorofila e o conteúdo de nutrientes nas folhas.…”

Poultry and cattle manure effects on sunflower performance, grain yield and selected soil properties in Limpopo Province, South Africa

“…The practice of mixing different manure types has been reported elsewhere with similar result. [16][17][18] Although the practice of mixing different organic manure types by smallholder farmers is common in most rural farming areas of South Africa, there has not been any agronomic evaluation of the practice. The aim of this study was to evaluate the application of three organic manures on sunflower performance and selected soil physical and chemical properties under rainfed conditions in the Limpopo Province.…”

Gas exchange and chlorophyll content in tomato grown under different organic fertilizers and biofertilizer doses

“…The increase in the WUE in relationship with the increase in the doses of biofertilizer may be due to the lower transpiration in relation to the photosynthetic rate, or the higher nutrient supply by increasing the doses of biofertilizer (Oliveira et al, 2014), as verified in lettuce plants in which organic fertilization improved water use efficiency (Santos et al, 2010). It was also verified in tomato plants, that organic fertilizers contribute to the adequate growth and development of plants and to the correction of nutritional deficiencies (Dinu et al, 2015;Kalbani et al, 2016).…”

“…On the other hand, the reduction of root-shoot ratio observed in plants cultivated on manure substrates and high doses of biofertilizer may mean that these plants, once the needs of the root growth have been satisfied by the greater absorption of the nutrients provided by the biofertilization, have passed; they direct their activities to the formation of the aerial part, such as leaves and fruits (Oliveira et al, 2014;Cruz et al, 2015;Kalbani et al, 2016).…”
