The Impact

The impact of intercropping green bean (Phaseolus vulgaris L.) with red beet (Beta vulgaris L. var. rubra) and radish (Raphanus sativus L.), two non-legume plants, on the plants’ yields, as well as the effect on occurrence and enumeration of microorganisms in the rhizosphere was studied. The intercrop efficacy evaluation, using Land equivalent ratio, revealed values above 1.0 for all intercropped treatments. Diversity of rhizobia from green bean nodules under different intercropping and fertilizing conditions was observed. On the basis of morphological and biochemical characteristics, 67 out of 158 isolates from green bean roots were selected as rhizobia (42.4%), confirmed by detection of 780 bp nifH gene fragments in nifH-PCR, and then clustered in 27 phenotype patterns. Production of exopolysaccharide succinoglycan was observed in 23 rhizobial isolates, while 6 were detected to solubilize tricalcium phosphate. Screening of genetic diversity using (GTG)5-PCR fingerprinting showed presence of six different patterns on the 92% similarity level.

The Impact

Louisiana sugarcane farmers in 2016 harvested 11.7 million Mg of millable sugarcane from 163,000 ha, producing 1.47 million Mg of raw sugar and an estimated 3.5 million Mg of bagasse. Even though Louisiana sugar mills use 80% to 90% of the bagasse for fuel production, another 350,000 to 700,000 Mg of bagasse accumulates each year. The conversion of the excess bagasse into biochar is one solution to reduce the excess supply. Research was conducted to determine the impact of sugarcane biochar as an amendment to soilless planting media for the production of green bean (Phaseolus vulgaris L.) seedlings. Sugarcane bagasse biochar (SBB) and pine biochar (PB) were each combined by volume with a commercial certified organic soilless growing media into 5 combinations (0%:100%, 25%:75%, 50%:50%, 75%:25%, and 100%:0%, biochars and growing media, respectively). Green bean variety ‘Bowie’ seeds were planted in each of the different planting mixtures. The particle size distribution for the two biochars are in stark contrast to each other with the PB particle median, mean, geometric mean, and mode much greater than those of the SBB. As amendments to the soilless greenhouse growing media, the biochars (SBB and PB) functioned very well, especially at the 25% and 75% levels. The 100% SBB performed as well as the 100% commercial soilless growing media and slightly better than the 100% PB when comparing seedling fresh and dry weights. The 100% PB is not recommended as a soilless growing media even with the supplemental fertilizer used in these experiments. These results indicate that the volume of a standard soilless greenhouse growing media can be successfully extended by adding 25% to 75% SBB and PB without reducing bean seedling growth. Future research is needed to evaluate these biochars for the production of additional plant species.

Heterocypris Incongruens

The aim of this work was to evaluate the impact of the thiophene-derived aminophosphonates 1–6 on seedling emergence and growth of monocotyledonous oat (Avena sativa) and dicotyledonous radish (Raphanus sativus L.), and phytotoxicity against three persistent and resistant weeds (Galinsoga parviflora Cav., Rumex acetosa L., and Chenopodium album). Aminophosphonates 1–6 have never been described in the literature. The phytotoxicity of tested aminophosphonates toward their potential application as soil-applied herbicides was evaluated according to the OECD (Organization for Economic and Cooperation Development Publishing) 208 Guideline. In addition, their ecotoxicological impact on crustaceans Heterocypris incongruens and bacteria Aliivibrio fischeri was measured using the OSTRACODTOXKITTM and Microtox® tests. Obtained results showed that none of the tested compounds were found sufficiently phytotoxic and none of them have any herbicidal potential. None of the tested compounds showed important toxicity against Aliivibrio fischeri but they should be considered as slightly harmful. Harmful impacts of compounds 1–6 on Heterocypris incongruens were found to be significant.

Growth Of Seedlings

Influence of aqueous extracts of aboveground organs of common crop weeds Stellaria media on germination and seedlings growth of radish (Raphanus sativus L. var. radicula Pers.) was studied. Three different cultivars of radish (i.e. ‘Rowa’, ‘Krakowianka’, and ‘Półdługa’) were used to investigate if Stellaria media could produce allelopathins and if the impact of allelopathins differs between cultivars. The influence of allelopathins in various form of extracts was checked, i.e. decoction, infusion, and macerate, as the impact on germination rate, seedling growth (length and mass), and electrolyte leakage. Compared to the control group (distilled water used) the germination rate of radish seeds was lower, independently of the type of S. media extracts used. The growth of seedlings differed between cultivars and form of extract. It was noticed the inhibition of seedling growth for ‘Półdługa’ cultivar independently of extract form. The growth of two other cultivars was stimulated by the infusion, and slightly inhibited by the decoction and macerate. The extracts reduced the outflow of electrolytes through the cell membranes of radish seedlings of all but one the analysed radish cultivars. The exception was the macerate, which in the ‘Rowa’ cultivar caused the increase of the electrolyte leakage.
