USE OF GRASS AND SPENT MUSHROOM COMPOST AS A GROWING MEDIUM OF LOCAL TOMATO (Lycopersicon esculentum Miller) SEEDLING IN THE NURSERY

Abstract

The objective of this study was to investigate the response of local tomato (Lycopersicon esculentum Miller) seedlings growth on media containing grass and spent mushroom compost in the nursery. The grass compost (GC) was produced by Research Center for Biotechnology-LIPI. Whereas the spent oyster mushroom (Pleurotus ostreatus) compost (OC) and spent paddy straw mushroom (Volvariella volvacea) compost (PC) were produced by Research Center for Biology-LIPI. Growing media of tomato seedling was a mixture of top soil (TS), rice husk charcoal (HC), grass compost (GC), spent oyster mushroom compost (OC) and spent paddy straw mushroom compost (PC) in the ratio of 1:1 as follows: TS+HC, TS+HC+GC, TS+HC+OC and TS+HC+PC. The experiments were arranged in Completely Randomized Design with three replications. Growth parameters observed i.e. seedling growth, dry weight production and leaf indices. Results showed that growing medium containing spent paddy straw mushroom compost was the best to improve seedlings growth in general. However, the lowest specific leaf area (SLA) and leaf area ratio (LAR) indices were obtained by the seedlings on the medium without compost. Correlation analysis showed that highest correlations were recorded for the TS+HC+OC medium. The tomato seedling growth was improved on the media containing compost in general.

Seedling Production of Pak Choy (Brassica rapa L. var chinensis) using Organic and Inorganic Nutrients

“…In contrast, there was not any significant difference correlation among growth parameters in K-6 (75% K0-3+25% K02). A different result showed by tomato seedling grown on various compost types; there was a very significant correlation between leaf area and both dry leaf weight and whole seedling dry weight, as well as seedling height and diameter (Priadi et al, 2016). The correlation among seedling growth parameters seemed to LW=Leaf dry weight; RW=Root dry weight; TW=Whole seedling dry weight; Means in the same column followed by the same letter are not significantly different (p<0.05)*) or very significantly different (p<0.01) **), n/a =not available be affected by the plant species and growing medium types.…”

“…Seedling leaf area was calculated using digital image analysis method (Bradshaw et al, 2007). This approach has been used by researchers in a variety of application (Priadi et al, 2016) due to the simple, inexpensive and accurate method. The water content of Pak Coy seedling was measured on a fresh weight basis method according to ISTA (2006) using a drying oven (Zenith Lab DHG9053A) at 130°C for 2 hours.…”

“…The viability of small seed including Pak Coy is usually tested using a paper substrate (Purbojati & Suwarno, 2006). However, seedling production is commonly using a locally organic substrate such as peat and vermicompost (Tuzel et al, 2014), spent mushroom compost (Priadi et al, 2016) on tomato seedling, and coconut coir dust on lettuce (Lactuca sativa L.) (Hossain et al, 2016). Moreover, production of organic transplants involves more than organic fertilizer and substrates and avoiding the use of non-approved pesticides.…”

Growth Response of Tobacco With Application of Liquid Organic Fertilizer

“…Pemanfaatan limbah juga terus dikembangkan untuk dijadikan campuran media tanam. Media tanam jamur merupakan salah satu potensi limbah substrat yang dimanfaatkan sebagai media tanam (Priadi et al, 2016) (Patricia SM et al, 2022).…”

Probiotic growth-stimulating capacity and antimicrobial activities of aqueous extracts of Lentinus crinitus (L.) Fr (polyporales, basidiomycota)

“…Aqueous extracts can be obtained directly from basidiomata collected in the field or using biotechnological tools such as submerged fermentation (SmF) and solid-state fermentation (SSF) have been used for the transformation of rice husk and other agricultural waste using strains of mushrooms, which can give it a high added value and obtain metabolites or products with food, feed, or pharmacological uses [ [30] , [31] , [32] ].…”
