Experiments to examine the effect of sowing time on the lupin cultivars Uniwhite, Uniharvest and Unicrop (L. angustifolius) and Weiko Ill (L. luteus) were sown in northern Tasmania in 1973 and 1974. The best yields resulted from autumn sowings in 1974 (3.7 t ha- 1) and from winter and spring sowings in 1973 (3.5 and 3.3 t ha-1, respectively). The results indicate that acceptable yields can be obtained from both autumn and early spring sowings. In addition, a number of factors are discussed that suggest spring sowing is safer and better suited to the cropping system. Yield differences between Uniwhite, Uniharvest and Unicrop were small for sowings between May and September, but Unicrop yielded better with later sowing. The yield of Weiko IIIwas poorer than the other cultivars except after very late sowing. Uniwhite and Uniharvest failed to mature when sown after late October.

Canola, Indian mustard, and wheat were grown under dryland conditions at Ariah Park and Cowra (canola only) in the cropping belt of New South Wales, Australia, to determine the effects of sowing time (canola and wheat) and nitrogen (N) fertiliser on the growth, grain yield, and yield components of the crops. Compared with an April sowing, the grain yield of canola at Ariah Park was reduced by 35% for a May sowing and by 67% for a July sowing. Canola yield at Cowra was reduced by 45% between early and late May sowings. Wheat yield declined by 35% between the May and July sowings at Ariah Park. Grain yields of canola and wheat at Ariah Park responded to N fertiliser in the April and May sowings, but not in the July sowing. Indian mustard had a higher yield than thecomparable sowing of canola. Canola yields at Cowra were more responsive to N fertiliser than at Ariah Park, and increased from 0.5 to 2.9 t/ha with 100 kg N/ha. For each day that sowing canola was delayed at both sites after Aprill—early May, anthesis was delayed on average by 0.52 days. For Dollarbird wheat, the delay in anthesis was 0.39 days per day sowing was delayed. Dry matter accumulation by the oilseeds was greatest during flowering, but before anthesis for wheat. Late sowing had little effect on the proportions of dry matter accumulated in a particular growth period. Irrespective of sowing time, grain yields and dry-matter harvest indices of the oilseeds were similar to values for wheat when differences in the biosynthetic costs of grain and straw production were taken into account. Late sowing usually resulted in a greater reduction in canola oil concentration than high N fertiliser rates. Canola oil concentration was reduced by 1.7 percentage points per 1mp;deg;C increase in mean temperature during grain filling as a result of sowing late. It was concluded that N fertiliser could not compensate for the yield reduction in canola and wheat due to sowing late. Early sowing was essential to achieve high oil levels in canola.

Spring Sowing

Cultivation of buckwheat (Fagopyrum esculentum Moench) under Mediterranean photothermal conditions could affect synthesis of the flavonoid rutin and its partitioning within the plant, thus affecting the nutraceutical value of plant products. We examined rutin concentration and yield in the forage and the grain of common buckwheat grown under Mediterranean field conditions, in response to sowing time, irrigation, growth stage at harvest, and variety. The highest rutin concentration and yield in the forage were obtained with late spring sowing, thanks to greater accumulation of solar radiation and higher efficiency of rutin synthesis per photothermal unit. Water supply promoted a more efficient use of light resources for both biomass accumulation and rutin synthesis. Rainfed conditions reduced biomass accumulation to a greater extent than rutin synthesis. Rutin concentration was highest in leaves, followed by inflorescences, stems and achenes, and in all plant parts it decreased with plant age. In the grain, rutin concentration was highest with late spring sowing, and rutin yield was highest with early spring sowing. Correlation analyses suggest that rutin synthesis proceeds from the leaves to the other plant parts. Our research demonstrates that buckwheat can be cultivated in Mediterranean regions as a source of rutin for medicine and for food and feed supplementation.

Cropping systems of safflower (Carthamus tinctorius L.) with faba bean (Vicia faba L.) under different fertility were compared with sole cropping of each crop during 2015 and 2016 at the Research Farm of Tabriz University in Iran. The treatments were cropping systems (safflower and faba bean sole croppings, intercropping systems of safflower and faba bean with ratios of 1:1 and 2:1), and nutrient levels (100% chemical fertilizers, 60%, 30% chemical + biofertilizers and no fertilizer). A factorial set of treatments based on a randomized complete block design replicated three times was used. Cropping system and fertility effects were significant for yield and yield components of each crop. Yield and yield components were increased with the integrated use of 60% chemical plus biofertilizers for both years, while seed yield was reduced by intercropping. Maximum land equivalent ratio (LER), relative value total (RVT), system productivity index (SPI) and monetary advantage index (MAI) were achieved in nutritive level of 60% chemical plus biofertilizers as intercropped plants in ratio of 1:1 for both years. The total actual yield loss (AYL) values were positive and greater than zero in all mixtures, indicating an advantage from intercropping over sole crops. Intercropped safflower had a higher relative crowding coefficient (RCC) than intercropped faba bean, indicating that safflower was more competitive than faba bean in intercropping systems. From this study, it is inferred that intercropping (safflower and faba bean) with integrated use of the reduced chemical and biofertilizers may give better overall yield and income than sole cropping of each crop species.

A field experiment was carried out to study the influence of sowing times on yield and yield components of barley (Hordeum vulgare L.). Seeds of four barley cultivars (BB 1, Karan 19, Karan 163 and Karan 351) were sown with four sowing times (5 November, 17 November, 29 November and 11 December). Most of the yield and yield components were significantly highest in 17 November sowing. Among the cultivars most of the characters showed their highest values in BB 1 and the lowest in Karan 19. Harvest index was found highest in Karan 351 and lowest in BB 1. Key words: Barley, Sowing time, Yield.   doi: 10.3329/jbs.v15i0.2154   J. bio-sci. 15: 139-145, 2007

A single sprinkler line-source was used to provide irrigation treatments to three tomato (Lycopersicon escu Mill.) varieties (`Baja', `Rowpac', and `Roza') during 1988 and 1989 in northwestern New Mexico. In both years, marketable fruit yield (Y) of all varieties increased linearly with increased irrigation (1). However, the regression coefficients describing the Y vs. I relationship differed with variety and year. In 1989, `Rowpac' Y ranged from 40.3 to 114.2 Mg ha-1 at levels of 31.5 and 62.5 cm, respectively. Yields of `Baja' and `Roza', while similar to those of `Rowpac' at low I levels, were 59% and 71% of `Rowpac' Y, respectively, at the highest level of irrigation. At any given I level, Y was lower in 1988 than in 1989. While average weight per fruit (wt/fruit) and number of fruit per plant (no/plant) increased with increasing I level in all varieties, increased Y in `Rowpac' had a higher positive correlation with no/plant (40 to 90) than with wt/fruit (85 to 120 g). Increasing Y in `Baja' on the other hand, correlated much better with increased wt/plant (100 to 195 g) than no/plant (20 to 45).

Yield And Yield Components

The low average grain yield (0.7 ton ha−1) of tef in Ethiopia is mainly attributed to low soil fertility, and inappropriate tillage and weeds control practices. Despite this, limited scientific information has been documented so far on their interaction effects on tef crop productivity in northern Ethiopia. The objective of this study was to assess the separate and interaction effects of tillage, fertilizer, and weed control practices on tef yield and yield components in the conditions of northern Ethiopia. A two-year study (2008-2009) was conducted using split-split-plot design with three replications. In the main plot, three tillage treatments: conventional tillage (6 times tillage passes) (T1), four times tillage passes (T2), and reduced tillage (single tillage pass at sowing) (T3) were applied. The fertilizer treatments in the subplots were: no fertilizer (F1); 23 kg N ha−1 (F2); 23 kg N ha−1 and 10 kg P ha−1 (F3); 23 kg N ha−1 and 2.5 ton manure ha−1 (F4); and 2.5 ton manure ha−1 (F5). The sub-subplot weed control treatments included farmer weed control practice or hand weeding (W1); 2,4 D at 0.75 kg ha−1 at five-leaf stage; 2,4 D at 0.75 kg ha−1 at six-leaf stage; 2,4 D at 1.5 kg ha−1 at five-leaf stage; and 2,4 D at 1.5 kg ha−1 at six-leaf stage. This study showed that the separate and interaction effects of tillage, fertilizer, and weed control practices significantly affected tef crop yield and yield components in both crop seasons. T2 increased tef yield by >42% over the other tillage and F3 increased yield by >21% over the other fertilizer treatments. Grain yield increased by >23% due to W1. This study thus suggested that promising treatments such as T2, F3, and W1 should be demonstrated at on-farm fields in order to evaluate their performance at farmers’ conditions.

Field Plots

Six-row barley outyielded 2-row barley which outyielded wheat and oats in field plots on non-irrigated saline soils in southern Alberta. Salinity reduced the number of 6-row barley spikes less than it did the number on other cereals compared to spike production on adjacent non-saline soils. More kernels per spike were maintained on 6-row barley than on the other cereals under the salinity stress but average kernel weight was not differentially affected. Although salinity reduced the germination of wheat to a greater extent than it did the other cereals, adequate stands of all cereals were established and germination was not a major factor except on a plot where salinity stress was combined with spring drought. Six-row barley did not maintain its salt-stressed yield advantage over the other cereals under the drought conditions on a non-saline soil. The tolerance of cereals to osmotic stress thus differed from the tolerance to drought stress under dryland field conditions.
