“…As already mentioned, phenolic acids are involved in plant growth, antioxidant defence, and plant/microbe interaction [ 56 , 57 ]. Indeed, these compounds can be secreted by roots and act as allelochemicals by suppressing the proliferation of pathogens [ 58 ].…”

Tomato (Solanum lycopersicum L.) is globally recognised as a high-value crop both for commercial profit and nutritional benefits. In contrast to the extensive data regarding the changes in the metabolism of tomato fruit exposed to UV radiation, less is known about the foliar and root metabolome. Using an untargeted metabolomic approach through UHPLC-ESI-QTOF-MS analysis, we detected thousands of metabolites in the leaves (3000) and roots (2800) of Micro-Tom tomato plants exposed to 11 days of short daily UV radiation, applied only on the aboveground organs. Multivariate statistical analysis, such as OPLS-DA and volcano, were performed to allow a better understanding of the modifications caused by the treatment. Based on the unexpected modulation to the secondary metabolism, especially the phenylpropanoid pathway, of which compounds were down and up accumulated respectively in leaves and roots of treated plants, a phenolic profiling was carried out for both organs. The phenolic profile was associated with a gene expression analysis to check the transcription trend of genes involved in the UVR8 signalling pathway and the early steps of the phenolic biosynthesis. The retention of the modifications at metabolic and phenolic levels was also investigated 3 days after the UV treatment, showing a prolonged effect on the modulation once the UV treatment had ceased.

“…This result suggested that the irrigation mode can affect the yields and qualities of tomato because CI and DI systems cannot directly and precisely contact the rhizosphere zone; thus, it is easy to cause the fixation and loss of nutrients, which will reduce the uptake nutrients from the roots and increase the accumulation of dry matter and reduce the yields and qualities of the crop. Meanwhile, the macroelements of nitrogen (N), phosphorus (P) and potassium (K) play an important role in the yields and qualities of plants [23][24][25][26]. We found that the NPK contents of the plants were significantly higher in the NPI treatment than in the CI and DI treatments (Table 3), which indicates that the higher frequency of NPI over a long period can maintain consistent nutrient concentrations in the root zone, promote the development of the root system, enhance the photosynthetic rate and chlorophyll content to promote photosynthesis and nutrient uptake and accumulation and finally increase the crop yield and quality [8,10].…”

The objective of this study is intended to explore the effect of maintain high efficiency water and fertilizer supply for improving the tomato production and soil bacterial communities by negative pressure irrigation (NPI) in greenhouse. The pot culture experiments consisted of three irrigation treatments: conventional irrigation (CI), drip irrigation (DI) and NPI, which have been conducted in greenhouse for two consecutive years. The study found that NPI reduced water consumption remained stable with slight variations on dynamic soil water content, as well as increased the water use efficiencies compared with CI and DI, respectively. The NPI reduced water consumption by 20% and 18% compared to CI in 2016 and 2017, respectively. Under NPI treatment, the variations in soil water content were stabilized, within the range of 12.3-14.7% in the two years, which was smaller than that of CI and DI treatments of 8.6-15.6%. Moreover, the tomato yields, fruit quality, uptake quantitates of nutrition and soil rhizosphere microbial diversity were increased in the NPI treatment comparison with the CI and DI treatments. With NPI, the yield of tomato was significantly increased by 26% and 8, 41 and 17% compared to that under CI and DI treatments in 2016 and 2017, respectively. NPI was also considered to benefit plant growth by increasing the abundances of Bacillus, Streptomyces and Pseudolabrys at the genus level. Therefore, NPI should be utilized as an advanced technique for saving water and producing high yields in future sustainable agriculture.

Penyakit gugur daun Pestalotiopsis (PGDP mengalami outbreak dengan luas serangan di Indonesia mencapai 382.000 ha pada tahun 2019. Akibatnya, penurunan produksi karet lebih dari 30%. Hingga saat ini, cara yang efektif untuk pengendalian penyakit ini belum dilaporkan. Upaya pengendalian penyakit dapat dilakukan dengan meningkatkan sistem pertahanan tanaman dan menekan jumlah inokulum di perkebunan. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi pupuk dan fungsida terhadap kerapatan tajuk dan penambahan produksi pada klon GT 1 yang terserang PGDP. Dibandingkan kontrol, pemupukan 100 % dosis rekomendasi meningkatkan kerapatan tajuk 4% dengan kenaikan produksi 3 g/p/s. Pemberian ekstra 25% Nitrogen dan ekstra Kalium dapat memicu kerapatan tajuk berturut-turut 5% dan 6% dengan kenaikan produksi 5 dan 6 g/p/s. Kerapatan tajuk terbukti meningkat baik dengan penyemprotan fungisida di gawangan maupun pengasapan pada daun muda masing-masing 9%, dan diiringi kenaikan produksi berturut-turut 5 g/p/s. Kombinasi aplikasi pupuk ektra 25% N, K dan fungisida pada gawangan dan fogging memberikan kerapatan tajuk 9% dan kenaikan produksi 10 g/p/s. Pemupukan berperan dalam meningkatkan tajuk dan produksi. Aplikasi fungisida di gawangan dan fogging dapat mempertahankan tajuk lebih baik.
