The use of bacterial inoculants can increase root nodulation and the seed yield of annual legumes. A six site-year study was conducted to determine the effect of formulations (peat-based powder vs. granules) and placement in the soil (seed-row vs. side-band) of Mesorhizobium inoculants on plant establishment and seed yield of chickpea (Cicer arietinum L.) in the semiarid Canadian prairies. Two market classes of chickpea, namely desi and kabuli, were grown on silt loam and heavy clay soils in southwestern Saskatchewan from 1999 to 2002. Inoculation reduced plant population by 10% for desi chickpea, but had no effect on kabuli chickpea. However, the use of inoculant increased seed yield by an average of 35% for desi chickpea and 7% for kabuli chickpea. On the heavy clay, soil inoculation increased seed yield by 16% for desi and 9% for kabuli compared with seed inoculation, whereas the yield increase due to soil inoculation, over seed inoculation, was 3% when the crops were grown on the silt loam. Granular inoculant applied in the seed row produced similar seed yields to side-banded inoculant. Inoculation delivery systems had a marginal impact on plant height, with no effect on the lowest pod height from the soil surface or days to maturity. Regardless of placement, soil inoculation with a granular form of Mesorhizobium was preferred over seed inoculation because of its greater positive impacts on plant establishment and seed yield for both desi and kabuli chickpea in this semiarid region.

Rhizobial Inoculants

The use of microbial inoculation may increase nodulation and seed yield of annual legumes. A study was conducted to determine the effect of formulations (seedapplied powder vs. soil-applied granular inoculants), placement of granular inoculants in soils (applied in the seed-row vs. sidebanded), and low rates of fertilizers in comparison to P-solubilizing microbes Penicillium bilaii on plant establishment, maturity, and seed yield of lentil (Lens culinaris Medik.) in the semiarid Canadian prairies. Green lentil was grown on a silt loam and a heavy clay soil in southwestern Saskatchewan from 1999 to 2002. Inoculated lentil with Rhizobium increased seed yield by 45% averaged across all 6 site-years. Granular soil inoculants increased lentil seed yield by 19% over seed-applied inoculants. Placement of soil inoculants in the seed row or side-bands produced similar results. On the silt loam soil, the use of rhizobial inoculants increased lentil seed yield by 15%, while the yield increase was 70% on the heavy clay. Starter N applied at a rate of 15 kg ha-1 increased seed yield by 13% for lentil grown on the heavy clay, but there was no effect on the silt loam. Phosphorus fertilizer applied at a rate 15 kg P ha-1 did not influence lentil establishment, growth or seed yield. Similarly, the P-solubilizing microbes P. bilaii did not influence plant growth or development, nor did it affect the seed yield of lentil. Soil granular rhizobial inoculants are preferred over seed-applied inoculants, fertilizers, or P-solubilizing microbes in lentil because of their strong and consistently positive impact on plant growth and seed yield in the semiarid Canadian prairies.

AbstractIt is unclear if additional inoculation with Bradyrhizobia at varying soybean [Glycine max (L.) Merr.] growth stages can impact biological nitrogen fixation (BNF), increase yield and improve seed composition [protein, oil, and amino acid (AA) concentrations]. The objectives of this study were to evaluate the effect of different soybean inoculation strategies (seed coating and additional soil inoculation at V4 or R1) on: (i) seed yield, (ii) seed composition, and (iii) BNF traits [nodule number and relative abundance of ureides (RAU)]. Soybean field trials were conducted in 11 environments (four states of the US) to evaluate four treatments: (i) control without inoculation, (ii) seed inoculation, (iii) seed inoculation + soil inoculation at V4, and (iv) seed inoculation + soil inoculation at R1. Results demonstrated no effect of seed or additional soil inoculation at V4 or R1 on either soybean seed yield or composition. Also, inoculation strategies produced similar values to the non-inoculated control in terms of nodule number and RAU, a reflection of BNF. Therefore, we conclude that in soils with previous history of soybean and under non-severe stress conditions (e.g. high early-season temperature and/or saturated soils), there is no benefit to implementing additional inoculation on soybean yield and seed composition.

Field experiments were conducted in Saskatchewan using chickpea (Cicer arietinum L.) to evaluate fall-applied granular rhizobial inoculant. Seed yield and percentage N derived from fixation generally did not differ between granular inoculant applied in the fall (FG) and seed applied peat-based powder (SP). Results suggest that FG applications may be an alternative to spring seed inoculation for chickpea. Key words: Chickpea, rhizobial inoculant, granular inoculant, nodulation, N2 fixation

Glasshouse and field experiments were conducted with chickpea (Cicer arietinum) rhizobia to determine the inoculation requirements of this highly Rhizobium-specific legume. There did not appear to be any host-strain specificity within the species. There was a strong nodulation response to inoculation with four strains (unaffected by time of sowing) even at a level of inoculant application below normal. In some field experiments, nodulation responses were not reflected in improved foliage dry matter production or seed yield. However, the correlations between degree of nodulation and plant growth and seed yield were significant. There was a distinct advantage in using solid inoculant applied in the row with the seed instead of conventional seed inoculation when fungicide-treated chickpea was being sown. Two strains, CB1189 and CC1192, were considered suitable for inoculants.

Fodder Production

Small grain cereals such as oats or wheat, when grown on fallowed land, provided fodder yields as high as or higher than those obtained from perennial forage containing alfalfa. However, on a land base comparison, yields of perennial crops were about double those of cereal grains. A 3-yr rotation using annuals in a crop–crop–fallow sequence improved the yield relationship over a crop–fallow rotation only marginally in this semiarid region. Yields of corn or sunflower row crops in rotations with fallow, or with cereals and fallow, were highly variable. Crude protein yields of the perennial forage crops on a given land base were about threefold those from annual crops.

Unit Basis

Russian wild ryegrass (Elymus junceus Fisch.) and alfalfa (Medicago media Pers.) pastures seeded in mixed rows, or in alternate rows, or in a cross-seeded pattern were grazed by cattle from 1974 to 1980 at Swift Current, Saskatchewan. The legume persisted when seeded alone in the two component separation patterns but had declined to only 15% in the mixed row stands. Daily liveweight cattle gains were largest from the cross-seeded pastures. On a land unit basis, the beef production from cross-seeded pastures was higher than alternate row pastures by 13% and mixed row pastures by 17%. The checkered pattern from cross seeding reduced runoff and erosion by water. No incidence of bloat occurred.

Terminal drought is known to decrease flower production, increase flower and pod abortion, and decrease yield of chickpea (Cicer arietinum L.), but the effects of early-season drought have not been evaluated. The influence of an early transient water deficit on flower and pod production and abortion, and seed yield and its components was evaluated in two chickpea cultivars, Rupali, a desi type, and Almaz, a kabuli type. Thirty-six-day-old plants were subjected to: (i) a transient water deficit by withholding water for 35 days, and then rewatered (WS), and (ii) kept well watered (WW) throughout. In the WS treatment the soil water content, leaf relative water content and leaf photosynthetic rate decreased after water was withheld and, following rewatering, recovered to the WW level. Despite the WS treatment being imposed at different phenological stages in the two cultivars, WS reduced flower number per plant by ~50% in Rupali and Almaz, respectively, compared with the WW plants. In WW plants, ~15% of flowers aborted in both cultivars, and 42 and 67% of the pods aborted in Rupali and Almaz, respectively, whereas in WS plants, 18 and 23% of flowers aborted and 27 and 67% of pods aborted in Rupali and Almaz, respectively. While seed growth in WS plants of Rupali and Almaz occurred primarily after the plants were rewatered, the duration of seed growth decreased by 17 and 36 days, the maximum rate of seed filling increased by 3 times and 5 times, and seed size increased by 26 and 16%, respectively, compared with the WW plants. Seed yield per plant in WS plants decreased by 31% in Rupali and 38% in Almaz compared with the WW controls. The early transient water deficit decreased flower production, but improved flower and pod development; increased the rate of seed growth and increased final seed size; and had a smaller effect on seed yield compared with chickpea subjected to terminal drought.

Abstract A description is provided for Ascochyta rabiei. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Cicer arietinum. DISEASE: Blight of gor chick pea (Cicer arietinum), attacks all above-ground parts of the plant; circular lesions on leaves and pods and elongate ones on petioles and stems. The pycnidia form in concentric areas on these lesions and in severe attacks the whole plant is killed. GEOGRAPHICAL DISTRIBUTION: Restricted to the Mediterranean region, S.E. Europe, S.W. Asia and also reported from Tanzania (CMI Map 151, ed. 2, 1966). Additional areas not yet mapped are: Lebanon, Turkey, USSR (Azerbaijan, Republic of Georgia, Moldavia). TRANSMISSION: Infection is carried both on and within the seed. Seed infestation in pods showing infection was 50-80%. Seed formation, size and germination and seedling growth are adversely affected (12: 264; 49, 3059). Conida are presumably dispersed by water-splash and viability is retained in host debris on the soil surface between crop seasons.

1. Over a period of six years seven field experiments were carried out to study the effect of the time of application of sulphate of ammonia to autumn-sown wheat.2. Three experiments were located on light gravelly soil which had been farmed highly for some years, and in those three cases sulphate of ammonia decreased yield, irrespective of time of application; the reduction in yield was of the order of 10 per cent. and is ascribed to more lodging and greater incidence of “foot-rot”.3. Three experiments were located on heavy clay soil in poor condition; in these sulphate of ammonia gave percentage increases in yield of 18, 20 and 7.4. Evidence is produced that early dressings of sulphate of ammonia do not affect germination or plant establishment, but that they tend to increase tiller formation by the end of February.
