The objective of this work was to evaluate the effects of cattle manure, reactive natural phosphate and biotite schist on the soil fertility, yield and nutritional status of Megathyrsus spp. cv. Massai. The experiment was conducted under field conditions, in a dystrophic Red Yellow Latosol (Oxisol). It was used a randomized block experimental design with the following treatments: three natural reactive rock phosphate from Algeria (Djebel-Onk) doses (0, 100 and 200 kg ha-1 of P2O5), three biotite schist doses (0, 150 and 300 kg ha-1 of K2O) and three cattle manure doses (0, 20 and 40 t ha-1). The application of natural phosphate increased dry matter yield, however, application of cattle manure and biotite schist did not influence this variable. Foliar levels of nitrogen, potassium and magnesium (cattle manure), phosphorous and boron (natural rock phosphate) and potassium (biotite schist) were influenced by the applied fertilizer doses. Only the levels of phosphorous in the soil and in the plant and levels of magnesium and boron in the plant show interaction with dry matter yield of Massai cultivar.

Micronutrient sufficiency ranges are of great importance in crop nutritional diagnosing for improved fertilizer recommendations under field conditions. The objective of this paper was establishing the micronutrients ranges in the cladodes for the evaluation of the nutritional status of ‘Gigante’ forage cactus pear. Micronutrients contents in cladodes and dry matter yield of 72 plots were used. The experiment was composed of four cattle manure rates (0, 30, 60, and 90 Mg ha-1 year-1), three spacings (l.00 × 0.50, 2.00 × 0.25, and 3.00 × 1.00 × 0.25 m), and two production cycles, in a 4 × 3 × 2 factorial plan, designed in randomized blocks, with three replicates. Sufficiency ranges of plots with dry matter ≥ 19.93 Mg ha-1 cycle-1 were determined as well as the mathematical chance for plots with dry matter ≥ 23.75 Mg ha-1 cycle-1 and the critical level. The sufficiency range, critical level and mathematical chance are, respectively, for each micronutrient, in mg kg-1: B, 22.3-32.7; 23.7; 20.36-27.94; Cu, 2.0-3.7; 1.6; 1.8-2.8; Fe, 61.1-126.6; 62.0; 35.8-85.3; Mn, 260.0-507.7; 111.0; 54.8-252.2; Zn, 34.5-57.8; 30.3; 19.7-48.5; and, Na, 29.8-56.2; 19.4; 26.6-42.7. For B, Zn, and Na, the sufficiency range, mathematical chance, and the critical level are adequate; for Cu, Fe, and Mn, the critical level and mathematical chance are more adequate for nutritional evaluation of `Gigante` forage cactus pear, associated with dry matter yield ranging from 21.8 to 31.2 Mg ha-1 cycle-1.

Determining the sufficiency range of essential macronutrients in plants is of utmost importance for successfully diagnosing the crop’s nutrient demands, thereby improving fertilizer recommendations. The aim of this study was to establish the macronutrients ranges in the cladodes for the evaluation of the nutritional status of ‘Gigante’ cactus pear. Macronutrients contents of cladodes and dry matter yield in 72 plots were used. The experiment consisted of four cattle manure rates (0, 30, 60, and 90 Mg ha-1 year-1), three spacings (1.00 × 0.50, 2.00 × 0.25, and 3.00 × 1.00 × 0.25 m) and two production cycles, arranged in a 4 × 3 × 2 factorial in randomized blocks, and three replicates. Sufficiency ranges of plots with dry matter ≥ 19.93 Mg ha-1 cycle-1 were determined as well as the mathematical chance for plots with dry matter ≥ 23.75 Mg ha-1 cycle-1 and the critical level. The sufficiency ranges, critical level and mathematical chance are, respectively, for each nutrient in g kg-1: N, 12.7-18.5; 14.4; 15.5-19.7; P, 1.0-1.8; 1.0; 0.4-1.7; K, 31.6-44.1; 31.9; 33.7-39.7; Ca, 23.2-32.8; 24.6; 25.0-29.6; Mg, 9.5-14.3; 10.2; 7.4-14.0; and S, 1.1-2.0; 1,1; 1.0-1.8. The mathematical chance model was adequate for all macronutrients except for P and Mg which showed low sufficiency range values. Sufficiency range and critical level of nutrients are useful for diagnosing macronutrient contents and improving the nutritional status of ‘Gigante’ forage cactus pear.

The aim of this study was to evaluate the behavior of chemical properties and crop yields during five years after liming, in a consolidated no-tillage system area and indicate a base saturation index to serve as a criterion for recommendation. The experiment was conducted in a randomized complete block design with four repetitions, being the treatments the five lime doses (0, 2.4, 4.8, 7.2 and 9.6 Mg ha-1) applied and maintained on the soil surface. Soil chemical properties were evaluated in eight soil sampling, in the layers 0 to 0.025; 0.025 to 0.05; 0.05 to 0.10; 0.10 to 0.15; 0.15 to 0.20 and 0.20 to 0.40 m, besides crop grain yield (wheat, soybean and corn) and black oat dry matter yield, totaling five years of evaluation. The surface liming in no-tillage system increased the exchangeable magnesium and calcium contents, base saturation and soil pH and reduced the exchangeable aluminum content. The cumulative grain yield (six crops) and black oat dry matter yield (three crops) was not influenced by liming. These results suggested, from this study conditions, that the value of 50% of base saturation should be adopted as a criterion for liming for crops implanted under consolidated no-tillage systems.

Samples of Christmas Island and Florida rock phosphates with different particle size ranges were applied to a phosphorus-deficient acid sandy soil. The rock phosphates were compared with monocalcium phosphate at various levels of addition of phosphorus. The fertilizers were mixed uniformly with either the top 1, 5, or 10 cm of the soil. Dry matter yield and phosphorus uptake in the tops of subterranean clover (Trifolium subterraneum) and the distribution (by weight) of the roots in the soil were determined. Monocalcium phosphate produced higher dry matter yields (tops and roots) than rock phosphates, even when the latter were applied in amounts containing four times the amount of phosphorus added as monocalcium phosphate. The concentration and uptake of phosphorus in the tops was also higher when monocalcium phosphate was applied, although the difference in concentration decreased as the plants matured. Dry matter yield and phosphorus concentration in the clover tops were increased by increasing the fineness of grinding of rock phosphate and by increasing the depth of mixing with the soil. Increasing the depth of mixing also produced a greater weight and more even distribution of roots. The yield of tops and roots was unaffected by the depth to which monocalcium phosphate was mixed, although shallow placement concentrated the distribution of the roots near the soil surface. Florida rock phosphate was a better source of phosphorus for subterranean clover than Christmas Island rock when the samples were coarsely ground, but both rocks were equally effective when ground to give 70 per cent < 100 mesh B.S.S.

In an experiment on Tippera clay loam soil at Katherine, N.T., between 1962 and 1965, a comparison was made of the effect of depth of placement of initial applications of superphosphate and Christmas Island rock phosphate dust on the yield of grain sorghum for the first three years of cropping on new land. Placement of 4 cwt an acre superphosphate or 12 cwt an acre rock phosphate in a layer at 8 inches depth gave lower grain, dry matter, and phosphorus yields than mixing the same amount and type of fertilizer in the 0-4 inch or 0-8 inch layers. There were no significant differences in grain, dry matter, or phosphorus yield between mixing in the 0-4 or 0-8 inch layers. Additional annual applications of 4 cwt an acre superphosphate banded with the seed increased grain and dry matter yield when the initial phosphate fertilizer was placed in a layer at 8 inches, but not when it was mixed in the 0-4 or 0-8 inch layers.

Background: Acidic soils limit the soil phosphorus availability to the crop plants because these soils have tendency to fix P as iron and aluminium phosphate. The present study aims to investigate the influence of phosphorus sources and levels on yield and nutrient uptake of rapeseed (Brassica campestris var. toria) in acidic soils of Meghalaya. Methods: A pot culture experiment was conducted during rabi season of 2016-17 wherein two sources of P (single super phosphate and Mussoorie rock phosphate) and six levels of P (0, 30, 60, 90, 120 and 150 mg P kg-1 of soil) were tested in two types of acidic soils (Alfisols, Inceptisols) in completely randomized design with three replication and rapeseed (cv. M-27) as test crop. Result: The highest mean dry matter yield of rapeseed (16.1 g pot-1) was recorded with 120 mg P kg-1 of soil. Subsequent increase in the level of P significantly decreased the dry matter yield by 4.6% over 120 mg P kg-1. The dry matter yield with Mussorie rock phosphate was lower as compared to single sulphur phosphate (SSP) at each levels of P irrespective of soil type. The concentration of P in plant dry matter of rapeseed increased with each successive levels of P in acidic soils with both P sources; however P uptake increased up to 120 mg P kg-1 soil.
