“…On the other hand, it can be suggested that fertilisation influences fruit characteristics involved in fruit resistance, such as fruit flesh fragility, translucency, which is increased by high N mineral fertilisation (Py et al, 1984), and fruit antioxidant system defence provided by phenolics (Cartelat et al, 2005). It would be useful to evaluate the impact of various types of fertilisation on Low-input pineapple crops with high quality fruit 299 pineapple phenolics, as was recently done by Larbat et al (2014) on tomato and who observed that an N shortage increased several phenolic contents.…”

Low-Input Pineapple Crops With High Quality Fruit: Promising Impacts of Locally Integrated and Organic Fertilisation Compared to Chemical Fertilisers

SUMMARYFruit and vegetable farming generally involves high levels of chemical inputs despite the fact that consumers are increasingly concerned about the sanitary and organoleptic aspects of fruit quality. Pineapple is largely subject to these issues since it is dominated by conventional monocropping with high levels of agrochemical inputs due to nitrogen (N) and potassium (K) fertilisation, weed management, crop protection and flowering induction. However, low-input pineapple cropping systems are both rare and little documented. Our study aimed at replacing all or part of the chemical fertilisers used with local organic fertilisers. It was conducted on the cultivar 'Queen Victoria', without pesticides or herbicides, in Reunion Island. We compared the impacts of three fertilisation treatments on pineapple growth and yield, fruit quality traits, symptoms of two major fungal diseases in fruit and production costs and labour times: (i) conventional: NPK fertiliser at recommended doses (265.5 kg ha −1 N-10.53 kg ha −1 P-445.71 kg ha −1 K); (ii) integrated: Mucuna pruriens green manure (240.03 kg ha −1 N, 18.62 kg ha −1 P, 136.11 kg ha −1 K) incorporated into the soil and a half-dose of NPK fertiliser and (iii) organic: M. pruriens green manure incorporated into the soil and foliar applications of sugarcane vinasse from a local distillery, rich in K (14.44 g L −1 ). Our results showed that NPK fertilisation could be replaced by organic fertilisers as well as by integrated fertilisation. 'D'-leaf analysis showed that vinasse supplies a largely sufficient K level for growing pineapples. With organic fertilisation, pineapple growth was slower, 199 days after planting vs. 149 days for integrated or conventional fertilisations, and fruit yield was lower, 47.25 t ha −1 vs. 52.51 and 61.24 t ha −1 , probably because M. pruriens green manure provided an early increase in soil mineral N, whereas N requirements are much higher four months after planting. However, the fruit weight (709.94 ± 123.53 g) was still within the size range required for the export market (600-900 g). Interestingly, organic fertilisation significantly reduced Leathery Pocket disease and produced the best quality fruit with the highest total soluble solids contents (TSS) and the lowest titratable acidity (TTA). Fruit quality was also significantly improved with integrated fertilisation, with fruit weight similar to that of conventional fertilisation. To conclude, these findings have implications for the sustainability of pineapple production and could lead to low-input innovative cropping systems that reduce production costs and develop local organic inputs.

“…Nutritional treatment design was adapted from Han et al (2014); it was based on previous knowledge acquired on the tomato plant (see Le Bot et al 2009;Larbat et al 2012Larbat et al , 2014 and established from optimal conditions ensuring maximal growth of tomato plants in our lab conditions (see details in Han et al 2014). From DAS 8, a full nutrient solution adjusted to pH 5.5 was supplied daily to plants in a fully crossed design combining two nitrogen levels (optimal nitrogen [ON] vs. insufficient nitrogen [IN]) with two water levels (optimal water [OW] vs. drought [DT]).…”

Nitrogen and water limitations in tomato plants trigger negative bottom-up effects on the omnivorous predator Macrolophus pygmaeus

Omnivorous Heteroptera predators play important roles in biological control of a wide range of pest insects. Their predation could be influenced by various biotic or abiotic factors. Here we examined the effects of nitrogen and water inputs to tomato plants (Solanum lycopersicum L.) on the predation strength of the omnivore Macrolophus pygmaeus Wagner (Hemiptera: Miridae) on eggs of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae). We tested the hypothesis that a change in plant status, manipulated by sub-optimal nutrients and water inputs, may influence predation on E. kuehniella by the predator M. pygmaeus. Nitrogen and water restrictions depressed the predation of E. kuehniella eggs by M. pygmaeus. Moreover, we observed a 30 % reduction in predator longevity on plants under low water inputs. Therefore, the negative bottom-up effect of nitrogen and water limitations (in tomato plants) toward M. pygmaeus may be detrimental for mirid predator-based IPM programs in tomato crops.

“…Other empirical formulae were assigned to cinnamic acid-like structures (CI1-3) by similarity with the CH backbone, although the presence of nitrogen suggested the presence of a primary amide derivative ( Table 2). Formation of amides with other amines, namely putrescine and spermidine, is well established in the literature for carboxylic acid metabolites in tomato extracts [16,17], thus explaining the hydrolysis of these secondary metabolites leading to the formation of CI1-3 ( Table 2). The semiquantitative distribution of CO and CI metabolites was not highly abundant, nor significantly different in root extracts derived from different bioeffector treatments and from control.…”

Background: In light of the growing interest for eco-compatible fertilization, tomato plant roots were treated with four different strains of microorganisms (B1-B4) capable of positively affecting plant growth. The methanolic extracts from treated roots were analysed by reverse phase ultra-high-performance liquid chromatography hyphenated with ion trap time-of-flight high-resolution mass spectrometry to compare their metabolites with that of control plants (B0). Results:We found, in both treated and control plants, several primary metabolites, such as fatty acids and coumaric acid, and other compounds associated with secondary metabolism pathways such as that of cyclopentaneoctanoic acid (CPOA) or hydroxyoctadecadienoic acid (HODE), and additional molecules which were not characterizable with the available data. A semiquantitative assessment of all metabolites became the basis for further processing the metabolic results by principal component analysis, which highlighted significant differences in the PC1 and PC2 components. The PC1 was particularly affected by the presence of arachidonic acid, myristic acid, and two unidentified metabolites. It effectively differentiated control plants from all bioeffectors treatments, and, in particular, the B4 treatment from the rest (B1-B3). The PC2 was mainly affected by palmitic acid, heptadecanoic acid, two CPOAs, one HODE and two unidentified metabolites. These metabolites successfully differentiated the B0 control from all the bioeffectors treatments, and, especially, showed a difference between B1 and B2. Conclusions:Our findings suggest that changes in secondary pathways of lipid metabolism may underlie the biostimulation exerted by the four microbial bioeffectors of this study, and that LC-MS coupled by multivariate analysis can easily fingerprint the metabolic alterations induced by bioeffectors in tomato roots.
