Solid Form

Sixteen field experiments were conducted to assess whether inoculant applied as a liquid or in solid form separately from the seed but into the seed bed could be used as a substitute for conventional methods of legume seed inoculation. The experiments were done over a period of 8 years, on several soil types, with both crop and pasture legumes. Criteria used to measure response included success of the applied strain of rhizobia in forming nodules, quality of nodulation, seedling establishment, foliage dry matter production, and seed yield. Under favourable conditions for sowing, solid and liquid inoculants were generally as good as seed inoculation at similar total rates of application in promoting root nodulation and plant growth. However, when conditions were unfavourable for survival of rhizobia, e.g. when seed was dusted with toxic fungicide or when germination was delayed owing to environmental circumstances, solid or liquid inoculant gave better nodulation and very often better plant growth and seed yield than seed inoculation. The implications of these findings on alternatives to conventional seed inoculation and how they might be applied to agricultural practice are discussed.

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.

SUMMARYField experiments conducted in two localities in two growing seasons on the effect of inoculating haricot bean showed that a local strain of Rhizobium significantly improved nodulation and usually increased the nitrogen content of plants. In three out of four experiments, increases in seed yield were obtained ranging from 20–145 Per cent (significant in two cases). Inoculation was better than 43 kg. N/ha. of combined nitrogen but not better than 86 kg. N. Soil inoculation gave better early nodulation than seed inoculation, but the difference diminished in the later stages of plant growth.

Abstract A new glass fertilizer (GF) system of main composition 60P2O5.30K2O.3.5ZnO. 3.5MnO.3Fe2O3 was developed in response to the needs of pea plants with bio-fertilizers (Rhizobium leguminosarum. Bv.vicieae, Bacillus megaterium var phosphaticum, Bacillus circulans).GF was prepared by the traditional melt quenching technique at 1150°C. Characterization of prepared system was done using FTIR spectra before and after immersion in a simulated actual agriculture medium like 2% citric acid and distilled water. During two winter seasons, two successful field experiments were conducted at Cairo University's Eastern Farm to determine the impact of chemical, glass, and bio-fertilizers on plant growth, yield attributes, and seed quality of pea plant. Control treatment were without any addition of recommended chemical fertilizers and other treatments were full dose of recommended chemical fertilizers (100%RDF), glass fertilizers at rate 60 kg fed− 1, Glass fertilizers at rate30 kg fed− 1, 50% RDF ,100%RDF + bio-fertilizers, Glass fertilizers at rate 60 kg fed− 1 + bio-fertilizers, glass fertilizers at rate 30 kg fed− 1+ bio-fertilizers, 50%RDF + bio-fertilizers. Plots received 60 kg fed− 1 glass fertilizers + bio-fertilizers show the highest significant increment in plant growth, number and weight of pods plant− 1, number of grain pods− 1, grain yield, biological yield, P%, k% in pea leaves and quality of pea seeds compared with plots without any addition (control) in both seasons.

Yield And Quality

Deficiency of copper (Cu) in Canadian prairie soils is not widespread, but whenever it occurs it can cause a drastic reduction in seed yield and quality of most cereals, especially wheat. Field experiments conducted in western Canada indicated that broadcast-incorporation of granular Cu fertilizers prior to seeding at 3-5.6 kg Cu ha-1 was usually sufficient to prevent Cu deficiency in wheat, and improve seed yield and quality. At lower rates (< 2.0 kg Cu ha-1), broadcast-incorporation of granular Cu fertilizers was not effective, while surface spray-broadcast followed by incorporation of liquid Cu fertilizers was much more effective in increasing seed yield of wheat in the first year of application. Surface broadcast without incorporation and seedrow-placed granular Cu fertilizers were much less effective in improving seed yield of wheat than their foliar or soil-incorporated applications. In the growing season, foliar applications of Cu at 0.20 to 0.28 kg Cu ha-1 to wheat at the Feekes 6 (first node of stem visible at base of shoot or stem elongation), Feekes 10 (sheath of last leaf completely grown or flag-leaf) and early boot growth stages were very effective in restoring seed yield, while Cu applications at the Feekes 2 (four-leaf) or Feekes 10.5 (complete heading) growth stage did not have a consistent effect to correct damage caused by Cu deficiency. Some Cu fertilizers (e.g., Cu oxide) were less effective than others in preventing/correcting Cu deficiency. Soil application at relatively high rates produced residual benefits in increasing seed yield for a number of years. The sensitivity of crops to Cu deficiency is usually in the order (wheat, flax, canary seed) > (barley, alfalfa) > (timothy seed, oats, corn) > (peas, clovers) > (canola, rye, forage grasses). Stem melanosis in wheat was associated with deficiency of Cu in soil, and the disease was reduced substantially with Cu application. A high level of available P in soil was observed to induce/increase severity of Cu deficiency in wheat. Soil analysis for diethylene triamine pentacetic acid- (DTPA) extractable Cu in soil can be used as a good diagnostic tool to predict Cu deficiency, but there was a poor relationship between total Cu concentration in shoots and the degree of Cu deficiency in crops. Application of Cu fertilizers to wheat on Cu-deficient soils also generally improved seed quality.

Rhizobial Inoculation

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

Seven rates of copper were applied to the soil prior to the sowing of strawberry clover (Trifolium fragiferumL. cv. Palestine) on an alkaline peat deficient in copper. Symptoms of copper deficiency were evident only on the untreated plots where the clover did not set seed nor persist into the second year.Over five years� production, 1.0 kg Cu/ha continued to provide adequate copper, with regular dressings of superphosphate, for maximum dry matter production and seed yield. It was found that seed yield was more sensitive than vegetative dry matter yield to sub-optimal copper supply. At the lowest rate of applied copper (0.125 kg/ha), the vegetative yield ranged from 53% to 80% of the maximum harvest yield, whereas the seed yield ranged from 15% to 50% of maximum yield.For tissue sampled in the spring, the proposed critical range for copper concentration in the youngest open leaf (YOL) for vegetative dry matter production is 3-35 mg Cu/kg whereas that for seed production is 4.5-5.5 mg Cu/kg. At other times of the year the critical concentrations were higher. It was not clear if this was due to environmental conditions or changing internal requirements for copper.The critical copper concentration range in whole top (WT) tissue of 3.0-4.0 mg/kg for vegetative dry matter production could be applied to all samplings. For seed yield the critical range for copper concentration in WT was 4.0-5.0 mg/kg for the spring harvests. The critical copper concentration in seed for seed production was 5.0-6.0 mg/kg. In the pasture situation a critical concentration of 5.0-6.0 mg Cu/kg in the WT should be adopted when the animal requirement is considered.

The response of Vicia sativa (cvv. Languedoc, Blanchefleur and Morava) and V. benghalensis (cv. Barloo) seed yield to seeding rate was examined in 9 field experiments across 2 years in south-western Australia. There were 2 types of field experiments: seeding rate (20, 40, 60, 100 and 140 kg/ha) × cultivar (Languedoc, Blanchefleur, and Morava or Barloo), and time of sowing (2 times of sowing of either Languedoc or Blanchefleur) × seeding rate (5,�7.5, 10, 15, 20, 30, 40, 50, 75 and 100 kg/ha).A target density of 40 plants/m2 gave 'optimum' seed yield of vetch in south-western Australia. In high yielding situations, with a yield potential above 1.5 t/ha, the 'optimum' plant density for the early flowering cultivar Languedoc (85–97 days to 50% flowering) was increased to 60 plants/m2. The later flowering cultivar Blanchefleur (95–106 days to 50% flowering) had an optimum plant density of 33 plants/m2 at all sites, regardless of fitted maximum seed yield. Plant density in the range 31–38 plants/m2 was found to be adequate for dry matter production at maturity of Languedoc and Blanchefleur. For the remaining cultivars Barloo and Morava we were unable to determine an average optimum density for either dry matter or seed yield due to insufficient and/or inconsistent data.

Simultaneous Use

Field experiments with chick peas (Rawat & Sanoria, 1977) and peas (Sanoria & Ram, 1979) showed a synergistic effect of a particular Rhizobium and Azotobacter on yield and quality of seed. Isolates of R. leguminosarum revealed differences in the yield and quality of lentil grown in pots and in the field (Mallik & Sanoria, 1980). As there is no evidence in the literature regarding the simultaneous use of Rhizobium and Azotobacter on lentil (Lens esculenta), this study was undertaken to assess their effect on the yield and quality of lentil in field.

Field experiments were conducted for three years at Pulses and Oilseeds Research Station, Berhampore, Murshidabad, West Bengal, India during rabi 2010-11, 2011-12 and 2012-13 to study the effects of farm yard manure (FYM), phosphorus and sulphur on yield parameters, yield, nodulation, nutrient uptake and quality of chickpea. The experiment was laid out in a factorial randomized block design with three replications having twelve treatment combinations viz. two levels of FYM (F0-0 t ha-1, F1 -5 t ha-1) as factor A , three levels of phosphorus (P0 -0 kg ha-1, P30 -30 kg ha-1, P60 -60 kg ha-1) as factor B and two levels of sulphur (S0 -0 kg ha-1, S20 -20 kg ha-1) as factor C. Experimental results revealed that yield attributing characters, yield and protein content of chickpea were significantly influenced by FYM, phosphorus, sulphur and interaction effects of these three factors. Significantly higher seed yield (2458.03 kg ha-1) was obtained with the application of FYM 5 t ha-1 over it’s non application. Application of 60 kg ha-1 phosphorus recorded significantly higher seed yield (2735.50 kg ha-1) of chickpea cultivar Anuradha. Application of 20 kg ha-1 sulphur recorded significantly higher seed yield (2532.32 kg ha-1) over it’s non application in a sulphur deficient soil. Among the interaction effects application of 60 kg ha-1 phosphorus and 20 kgha-1 sulphur in Farm yard manure(5 t ha-1 ) treated plot recorded highest seed yield (2979.3 kg ha-1) . Application of sulphur 20 kg ha-1 increased the nodule no. by 14.4 %. Application of 60 kg ha-1 phosphorus and 20 kg ha-1 sulphur in Farm yard manure treated plot (5 t ha-1) increased the nodule no. by 62.3%. Varying levels of phosphorus along with sulphur and FYM significantly improved the nutrient uptake by chickpea in a sulphur deficient soil. Application of 60 kg ha-1 phosphorus and 20 kg ha-1 sulphur in Farm yard manure treated plot (5 t ha-1) along with recommended dose of nitrogen and potassium proved to be the best treatment combination for increasing the productivity of chickpea and thereby increasing the pulse production of the country.
