FYM application resulted in an increase of 145, 97, 55, 40, 39 and 43% for dry matter. Fresh matter, germination percentage, plant height, root length and root diameter, respectively, averaged over varieties and seasons.
Brachiaria Brizantha Response To Phosphorus Rates In The Nutrient Solution, F A. Monteiro, R A. Martim, W T. Mattos
Brachiaria Brizantha Response To Phosphorus Rates In The Nutrient Solution, F A. Monteiro, R A. Martim, W T. Mattos
IGC Proceedings (1977-2023)
Seven phosphorus rates in the nutrient solution were studied in a greenhouse experiment for Brachiaria brizantha (Hochst) Stapf. Plants had 54 days of growth and 49 days of regrowth. Significant responses in forage yield, tiller number and root dry weight were found. Plant tops were divided into four parts and phosphorus concentration in each one significantly changed with phosphorus rates. Sampling of the young leaf blades and analyzing for phosphorus is proposed for diagnostic purposes. A critical phosphorus concentration of 1.2 g kg-1 is suggested as the critical level in the young leaf blades.

Effects Of Different Phosphate Fertilizers On Pasture Nutrition And Soil Phosphorus In Canterbury, New Zealand, L M. Condron, K M. Goh
Effects Of Different Phosphate Fertilizers On Pasture Nutrition And Soil Phosphorus In Canterbury, New Zealand, L M. Condron, K M. Goh
IGC Proceedings (1977-2023)
A field trial was conducted over 6 years to assess the relative performance of three phosphate (P) fertilisers of differing solubility (single superphosphate, ‘longlife’ superphosphate, ‘reactive’ phosphate rock) on a permanent pasture at Methven in Canterbury, New Zealand. Plant P uptake data showed that while the overall relative effectiveness of the fertilisers was closely related to their water-soluble P content (single superphosphate > ‘longlife’ superphosphate > ‘reactive’ phosphate rock), the agronomic efficiency of the sparingly soluble phosphate rock fertiliser improved markedly with time. Soil P analysis demonstrated that significant dissolution of phosphate rock had occurred in the soil, and the findings of …

Evaluation Of Different Bradyrhizobium Sp Strains On Nitrogen Fixation Capacity In Four Forage Legumes, F O. Gallardo, E S. Lopes, M C. Diez
IGC Proceedings (1977-2023)
Eleven available strains of Bradyrhizobium sp were used to test four forage legumes, Crotalaria juncea (Crotalaria), Cajanus cajans (Guandu), Styzolobium deeriagianum (Mucuna-Ana) and Cyamopsis tetragonoloba (Guar) for symbiotic N-fixation ability. Greenhouse experiments were conducted for nine weeks in order to evaluate shoot, root, and nodule dry weight, nodule number, and shoot nitrogen content. Four strains presented relative nitrogen efficiency (RNE) over 100% with Crotalaria cultivar, whereas only one strain was more efficient with Guandu and Mucuna cultivars. Strain 633 was the only one which presented a high yield with Crotalaria, Guandu and Mucuna-Ana cultivars.

Long Term Effects Of Liming A Basalt-Derived Soil, On Lucerene And Phalaris Production, K.M. F. Reed, J F. Chin
IGC Proceedings (1977-2023)
Lime incorporated into a basalt-derived clay loam lowered exchangeable aluminium in soil. Soil pH was still elevated, 9 years after 2 t/ha of lime was incorporated. With lower rates of lime the density of lucerne plants declined. Lucerne yield more than doubled with lime. After six years, the area was sown to a phalaris-clover pasture. A 15% increase in the yield of phalaris was recorded from limed plots over the next three years. Despite this, 11 years after liming, herbage P concentrations increased with lime, from 0.28% to 0.35%.

Can Maize Influence The Dissolution Of Low Water Soluble Phosphorus Fertilizers?, S Sinaj, E Frossard
IGC Proceedings (1977-2023)
The objectives of this study were to evaluate the respective importance of maize (Zea mays) and soil properties on the dissolution of two sparingly soluble P fertilizers. The surface horizon of an acidic and a calcareous soils were amended with Thomas’ slag or phosphate rock and were either incubated or cultivated with maize. Maize cultivation increased the rate of dissolution of both fertilizers in both soils. Its influence remained limited compared to fertilizer dissolution in the incubated acidic soil. In the calcareous soil, however, the presence of maize increased significantly the rate of fertilizer dissolution compared to that observed in …

Phosphorus Availability, Defoliation Tolerance, And Genetic Differentiation In White Clover, D F. Chapman
IGC Proceedings (1977-2023)
The genetic composition of mixed populations of white clover growing in low fertility, grass-dominant hill pastures was estimated four and eight years after populations were established. Populations were based on an adapted ('Grasslands Tahora') or poorly adapted ('Grasslands Huia') cultivar, and received either no fertiliser, or 35kg P /ha /year. The P response curve of surviving plants was also determined, and compared with plants grown from 'standard' seedlines of the respective cultivars. Between years 4 and 8, the proportion of the populations constituted by plants true-to-type for the sown cultivar remained steady at 56 - 58% for Tahora, but fell …

Potassium Rates For Macrotyloma Axillare Growth, R A. Martim, F A. Monteiro, P.R. L. Portilho
IGC Proceedings (1977-2023)
The response of the tropical forage legume macrotiloma guata (Macrotyloma axillare (E. Mey) Verdc) to potassium rates was studied in a greenhouse experiment. The plants were grown in nutrient solution with seven potassium (K) rates, 0; 3.5; 7; 21; 35; 105 and 245 mg l-1 of solution, in randomized complete block design, with four replications. There was significant response of the legume to potassium rates. Considerations are made on the influence of these levels on plant dry matter yield in two harvests, root dry matter production and potassium and magnesium concentrations in the plant tissue.
Phosphogypsum As A Source Of Nutrients For Bahiagrass, J E. Rechcigl, I S. Alcordo
Phosphogypsum As A Source Of Nutrients For Bahiagrass, J E. Rechcigl, I S. Alcordo
IGC Proceedings (1977-2023)
Phosphogypsum is a by-product of the manufacture of phosphoric acid from phosphate rock and is a potential source of sulfur and calcium for crops. There are currently more than 700 million Mg of phosphogypsum in Florida alone stacked in waste piles and an additional 30 million Mg produced annually. A 3-year study was conducted to determine whether addition of phosphogypsum to bahiagrass would increase production and quality. Results indicate that addition of up to 4.0 Mg/ha phosphogypsum increased bahiagrass yields, protein content, and in vitro digestibility of forage. This study has demonstrated that phosphogypsum can be used as an alternative …

Co2 Enrichment And Temperature Effects On Productivity Of Field-Grown Phalaris And Subterranean Clover, J M. Lilley, T P. Bolger, R M. Gifford
IGC Proceedings (1977-2023)
Pure and mixed swards of Phalaris aquatica and Trifolium subterraneum were exposed to cool (ambient) and warm (cool +3oC) temperatures, at both 380 and 690 ppm CO2 concentrations in field temperature gradient tunnels for 5 months. In general, clover and the mixture had similar forage productivity in each treatment, while phalaris was less productive. Elevated CO2 increased clover production 40% in the monoculture and the mixture. Higher temperatures reduced clover regrowth at ambient CO2 and reduced the response to elevated CO2 in the monoculture but not in the mixture. In contrast, phalaris regrowth in the monoculture was not increased by …

Nutritive Value Of Guineagrass Cultivars In The Winter As Influenced By Nitrogen Fertilization, N.F G. Rethman, W.A J. Steenekamp
Nutritive Value Of Guineagrass Cultivars In The Winter As Influenced By Nitrogen Fertilization, N.F G. Rethman, W.A J. Steenekamp
IGC Proceedings (1977-2023)
The monitoring of yield, structure and nutritive value of four Panicum maximum (Guineagrass) cultivars, utilized as standing hay in the winter, yielded valuable data on the relative importance of nitrogen fertilization and cultivar. While nitrogen had a strong influence on yield and crude protein content it was the differences between cultivars, with respect to soil adaptation and structure, which played a dominant role. It is recommended that future research place particular emphasis on the adaptation of cultivars and genotype differences in structure.
