Tomato yield and quality under various combinations of organic compost

Abstract

ABSTRACT:The number of growers and planted area dedicated to organic farming have increased considerably. Consequently, demand has increased for alternative organic composts in terms of quantity and new options for direct use with crops. Making use of local industrial byproducts is also important throughout Brazil and the rest of the world. Therefore, it was evaluated the effect of eight types of organic composts, produced with different percentages of poultry litter and crushed sugarcane on tomato yield and quality. (0, 10, 20, 30, 40, 50, 50, 60 and 70%) yielding eight types of alternative Bokashi used as organic compost in the production of two tomato cultivars (Santa Clara and the Verano hybrid). It was found that the various formulations of alternative Bokashi, except the alternative Bokashi B1, strengthened components of tomato yield and quality. We found that composts of poultry litter and crushed sugarcane increase tomato yield and quality and can be and excellent alternative, especially for organic farmers.

Microbial transformation of traditional fermented fertilizer bokashi alters chemical composition and improves plant growth

“…Cucumber and kale seedlings grown in bokashi-amended soils grew significantly larger and had higher leaf chlorophyll concentrations compared to seedlings grown in compost-amended soils or in soil alone (Figure 2a). Our finding that bokashi improves plant growth is consistent with previous studies (Álvarez-Solís et al, 2016; Aurora Gomez-Velasco et al, 2014; Bautista-Cruz et al, 2014; Boechat et al, 2013; França et al, 2016; Jaramillo-López et al, 2015; Lima et al, 2015; Peralta-Antonio et al, 2014). The positive correlation between bokashi amendments, leaf chlorophyll concentration, and plant biomass further suggests a pathway for enhanced plant growth by bokashi through increased bioavailable N concentrations (Figure 2b), as does the positive correlation between NH 4 + concentrations of bokashi and chlorophyll concentrations in plant leaves (Fig.…”

“…Unlike compost, bokashi matures rapidly, in just two weeks, and fundamentally integrates animal waste. Various studies have illustrated the efficacy of bokashi as a fertilizer that improves plant growth (Álvarez-Solís et al, 2016; Aurora Gomez-Velasco et al, 2014; Bautista-Cruz et al, 2014; Boechat et al, 2013; França et al, 2016; Jaramillo-López et al, 2015; Lima et al, 2015; Peralta-Antonio et al, 2014) and several have investigated the amendment’s nutrient content (Álvarez-Solís et al, 2016; Aurora Gomez-Velasco et al, 2014; Boechat et al, 2013; Lima et al, 2015; Peralta-Antonio et al, 2014).…”

Bokashi, Boiled Manure and Penergetic Applications Increased Agronomic Production Variables and May Enhance Powdery Mildew Severity of Organic Tomato Plants

“…However, for arugula (Eruca sativa L.) and radish (Raphanus sativus L.), higher yields have been achieved with 10% and 5% BM, respectively [2]. Effective microorganism (EM) Bokashi is a well-known soil amendment used in agriculture [3,4], and has been tested with promising results for tomato [5,6], arugula [2], radish [2], and lettuce (Lactuca sativa L.) [7]. Based on 130 long-term experiments, organic amendments provided stability in plant and fruit production, and may increase yield by up to 15% in tropical conditions [8].…”

Revamping soil quality and correlation studies for yield and yield attributes in sorghum-legumes intercropping systems

“…Soil fertility is continuously on decline despite the use of chemical fertilizers on a wide scale. Organic farming has yet not got required support to be widely practiced for many crops owing to comparatively lesser yields (KUMAR et al, 2016;FRANCA et al, 2016). Legumes inclusion in cropping systems might lead to soil fertility buildup due to biological nitrogen fixation as well as other physico-chemical properties improvement owing to green manure addition by leaf shattering in the longer run.…”
