This study determined whether beneficial effects obtained with infection by vesicular–arbuscular mycorrhizal (VAM) fungi during early growth of cucumber are maintained through to maturity. Greenhouse cucumbers (Cucumis sativus L. 'Corona' and 'Carmen') were grown in VAM-inoculated (Glomus intraradices Schenck & Smith) or noninoculated autclaved sandy soil with supplemental phosphorus (P) ranging from 90 to 720 mg P plant−1 wk−1. These P treatments resulted in leaf P levels that spanned the range from deficient to sufficient, based on published data for mature cucumber plants. Leaf and mainstem development, number of fruit per plant, and harvest index were enhanced by increasing P levels in all studies. Low levels of P nutrition resulted in deficiency symptoms that were well correlated with deficient concentrations of leaf P. Mature plants maintained a relatively high level of infection by G. intraradices at low and moderate levels of P nutrition; however, depending on the cultivar, VAM infection either had no effect, or slightly depressed leaf and stem growth. The VAM infection stimulated earlier flowering and fruit production, but a longer fruit abortion period precluded increases in final fruit yield. The reduced shoot development and longer interval of fruit abortion characteristic for VAM-infected plants may be due to increased stress imposed by the collective sink requirements of the fungus and developing fruit.

Greenhouse Cucumber

The growth response of greenhouse cucumber (Cucumis sativus L.) to infection by vesicular–arbuscular mycorrhizal (VAM) fungi and to 4, 12 and 20 mg L−1 of phosphorus (P) nutrition was characterized over 38 d of plant establishment. Although maximum growth rates were not reached with the P levels studied, foliar concentrations of P were consistent with those published for healthy cucumber plants. Plants were highly receptive to colonization by Glomus mosseae, G. dimorphicum and G. intraradices. Infection by all species decreased as P nutrition increased; however, growth rates of primary yield components (e.g., stem and leaf dry weights, leaf area) of VAM-infected plants were greater than those of noninfected plants at all levels of P nutrition. The VAM-enhanced growth was similar to that induced by increases in P nutrition. The VAM-infected plants had lower concentrations of soluble nitrogen (N) than noninfected plants early in development; however, N concentrations were equal by 38 d after planting. Total soluble carbohydrate concentration of leaves of noninfected plants increased 62% faster than that of leaves of VAM-infected plants, possibly due to decreased export and a higher degree of P stress in the non-infected plants. Relative to noninfected plants, higher concentration of soluble carbohydrates in roots of VAM-infected plants may indicate increased sink demand to support the symbiosis. Since VAM stimulated growth at levels of P nutrition considered nondeficient by tissue analysis, use of VAM to accelerate the early development of transplants may be advantageous to the greenhouse industry.

This study aimed to determine the effect of arbuscular mycorrhizal fungi (AMF) and phosphate (P) fertilizer on the nutrient content, phosphate uptake and in vitro digestibility of alfalfa (Medicago sativa L.).The research was conducted at green house of Forage and Pastures Science Laboratory, Faculty of Animal Science Universitas Gadjah Mada. The experiment was arranged in Completely Randomized Design using 3x4 factorial patterns with four replications. The first factor was dosage of phosphate fertilizer SP 36 (0, 60, and 120 kg/ha). Second factor was the dosage of AMF (0, 0.8, 1.6, and 2.4kg/ha). The variable measured was nutrient contents (crude protein, dry matter, and organic matter), total P uptake and dry matter and organic matter in vitro digestibility. The results showed that the interaction of AMF and P fertilizer had no significant effect on crude protein and total P uptake, but highly significant effect on the parameters of dry matter, organic matter and dry matter and organic matter in vitro digestibility.
