A summary of seed yield data from 19 fungicide trials in perennial and hybrid ryegrass (Lolium spp) seed crops conducted over a 12 year period is presented Seed yields from the best fungicide treatments were increased on average by 25 in forage ryegrass (390 kg/ha) and 42 in turf ryegrass (580 kg/ha) Seed yield increases were associated with the control of stem rust and/or maintaining green leaf area during seed fill In turf ryegrass (susceptible to stem rust) delaying the first fungicide application until stem rust appeared resulted in seed yields that were not different (P>005) from the untreated experimental controls whereas early fungicide applications from the beginning of reproductive development increased seed yield by between 36 and 42 Fungicide mixes of a triazole plus a strobilurin usually gave higher seed yields than using either fungicide type alone

SUMMARYPhaseolus vulgaris (cv. Provider) was assessed as a vegetable and seed crop in southeast England. Experiments were designed to simulate ‘pick your own’ harvest systems which are becoming increasingly popular. Edible pods were removed on either one or two occasions at varying developmental stages, remaining pods being left to produce seed. The yield of edible pods increased considerably as pod removal was delayed but subsequent seed yield was reduced. However, depodded plants showed compensatory increases in mean seed weight so that seed yield reduction was less than expected.Results are discussed in relation to decline in seed moisture content and the dual use of this crop for vegetable pod and seed. It is concluded that dual use is not convenient for large-scale agricultural operations. ‘Pick your own’ programmes utilize the potential of this crop more efficiently than present mechanical harvesting systems.

Vegetative and reproductive development of a range of soya bean cultivars was studied over a series of planting dates in both hill plots and row culture at Redland Bay, Qld. Responses in the extent of vegetative and reproductive development were related to changes in the phasic developmental patterns. The duration and extent of vegetative development for the various cultivar-planting date combinations were closely associated with the length of the period from planting to the cessation of flowering. Thus, vegetative growth was greatest for those planting dates which resulted in a delay in flowering and/or extended the flowering phase. Similarly, genetic lateness of maturity among cultivars was associated with more extensive vegetative development. Seed yield per unit area increased within each cultivar as the length of the growing period was extended until sufficient vegetative growth occurred to allow the formation of closed canopies under the particular agronomic conditions imposed. Further increases in the length of the period of vegetative growth failed to increase seed yield, and in some cases seed yields were actually reduced. Biological efficiency of seed production (BE) was negatively correlated with the length of the vegetative growth period. Differences in BE among cultivar-planting date combinations were large. It is suggested that maximization of seed yield will necessitate an optimum compromise between the degree of vegetative development and BE. Optimum plant arrangement will therefore vary, depending on the particular cultivar-planting date combination. ___________________ \*Part I, Aust. J. Agric. Res., 24: 67 (1973).

Coulman, B., Loeppky, H. and Entz, M. 2015. The effect of late fall seeding time on the seed production of Italian ryegrass. Can. J. Plant Sci. 95: 641–645. Italian ryegrass (Lolium multiflorum Lam.) is a cool-season grass, which behaves as an annual in the Great Plains region of western Canada and is used as a grazing crop. Italian ryegrass requires vernalization for reproductive development to occur. Late fall (dormant) seedings, which have been used for annual crop species, have often resulted in earlier developing seedlings in the spring and higher yield than spring seedings. For Italian ryegrass, dormant seedings may result in vernalization of early-spring-germinating seedlings, allowing seed production without having to overwinter established plants. The objective of this study was to compare the seed yield and stand establishment of late fall (dormant) and spring seedings of Italian ryegrass at three locations in the Great Plains region of western Canada. Stand establishment was assessed by measuring tiller density in the month of June, and these densities were greater for spring than late fall seedings. Most spring seedings had no reproductive development and, thus, no seed yield; however, most late fall seedings produced seed the following year, indicating that vernalization of early-developing seedlings did occur. There were significant differences in seed yield among the four cultivars tested and among sites. Based on the high variation in seed yield among cultivars and sites and the relatively low yield levels obtained, late fall seedings of Italian ryegrass cannot be recommended in the Great Plains region of western Canada.

Seed yield and quality of carrot (Daucus carota var. sativa DC.) were influenced by a wide range of water application regimes and levels. Irrigation treatments were imposed beginning at the time of extension of the primary umbel and extending throughout the reproductive development period. The three application regimes used were: 1) a high-frequency, low water deficit treatment [100% of daily accumulated crop evapotranspiration (ETc)]; 2) a series of five low-frequency (irrigated after 30 mm of accumulated ET,) application treatments with a range of water deficits from moderate to minimal (40% to 120% of ETc applied); and 3) a series of three treatments that had rapidly developing water deficits applied by terminating irrigation at 7, 5, and 2 weeks before harvest after being grown under low-stress conditions. Pure live seed (PLS) yield was optimized by different treatments within each of the three application regimes. Maximum yields were achieved with short-term (2-week) rapidly developing water deficits near harvest, moderate deficit irrigation with 60% to 80% of ETc applied after 30 mm of ETc, or with a low water deficit, high-frequency application. Seed germination percentage decreased as the amount of applied water increased. This effect was more pronounced in the later-developing umbel orders. However, seed quality measured as seedling root length was improved with increasing water application.
