“…Coir pith has been found to be an effective substitute for natural peat. , The pH of the composted coir pith is close to neutral, while the pH of natural pith is acidic. − The electrical conductivity of the composted coir pith drops to 0.23 dS/cm, in comparison to over 0.7 dS/cm for peat moss . Because coir pith is organic in nature, there are some advantages of its use in agriculture …”

Hillocks of coir pith accumulate in the vicinity of coconut coir-fiber extraction units, of which disposal and management remain a major problem. Southern states of India, especially Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, and Orissa, face this problem. A simple technology for accelerated composting of coir pith was developed, and on-site composting of coir pith hillocks was demonstrated. The composting of pith was complete in 21 days. The composted pith was an excellent organic manure, with a reduced C/N ratio of 20:1, pH of about 6.5, and electrical conductivity of 0.23 dS/cm, making it a more desirable soil organic manure. The composted pith did not contain or carry weeds and undesirable pathogens, thus providing a rich soil environment for plant and vegetation growth.

“…First, we evaluated the thermotolerance levels of five tomato cultivars based on physiological measurements after heat stress treatment at the seedling stage. Among the five cultivars included in this study, 'Arkansas Traveler' (AT) was used as a candidate thermotolerant cultivar (Vavrina et al, 2013). The other four cultivars tested were 'Super First' (SF), 'Momotaro 8' (Mm8), 'Rouge Grosse Lisse' (RGL) and 'Saturn' (Sat).…”

Heat stress is a severe challenge for plant production, and the use of thermotolerant cultivars is critical to ensure stable production in high-temperature-prone environments. However, the selection of thermotolerant cultivars is difficult due to the complex nature of heat stress and the time and space needed for evaluation. In this study, we characterized genome-wide differences in gene expression between thermotolerant and thermosensitive tomato cultivars and examined the possibility of selecting gene expression markers to estimate thermotolerance among different tomato cultivars. We selected one thermotolerant and one thermosensitive cultivar based on physiological evaluations and compared heat-responsive gene expression in these cultivars under stepwise heat stress and acute heat shock conditions. Transcriptomic analyses reveled that two heat-inducible gene expression pathways, controlled by the heat shock element (HSE) and the evening element (EE), respectively, presented different responses depending on heat stress conditions. HSE-regulated gene expression was induced under both conditions, while EE-regulated gene expression was only induced under gradual heat stress conditions in both cultivars. Furthermore, HSE-regulated genes showed higher expression in the thermotolerant cultivar than the sensitive cultivar under acute heat shock conditions. Then, candidate expression biomarker genes were selected based on the transcriptome data, and the usefulness of these candidate genes was validated in five cultivars. This study shows that the thermotolerance of tomato is correlated with its ability to maintain the heat shock response (HSR) under acute severe heat shock conditions. Furthermore, it raises the possibility that the robustness of the HSR under severe heat stress can be used as an indicator to evaluate the thermotolerance of crop cultivars.

“…Moreover, peat is a non-renewable resource, whose extraction causes the destruction of ecological environment, has stimulated interest in finding new materials replacing peat [6,7]. Numerous studies have been published on the potential use of diverse wastes of urban, agro-industrial or agricultural origin as substrates for peat in the production of vegetable plug transplants [6,8,9]. However, the results concerning the suitability of these composts have varied significantly and were not satisfied [6].…”

The aim of this investigation was to evaluate solid digestate as a growing substrate for plug seedlings. Four mediums prepared from solid digestate, vermiculite, perlite and activated carbon were used to determine optimum growing substrate for tomato seedlings (Zhongshu six). The substrate used in this study mixed as solid digestate: vermiculite: perlite: activated carbon were (m:m): 4:13:2:1, 8:9:2:1, 12:5:2:1 and 16:1:2:1, respectively. Besides, peat: vermiculite of 2:1 (v:v) was used as the control. Various seedling indices were measured to assess the quality of the substrates. Tomato seedlings grown in solid digestate: vermiculite: perlite: activated carbon of 16:1:2:1 (m:m) displayed the best quality compared with all the other treatments, due to a correct balance between the digestate nutrient supply and the physical properties provided by vermiculite, perlite and activated carbon. Solid digestate could be a potential alternative for plug seedlings.
