Glycine Max L

The experiment was conducted in three locations Jari, Chefa and Sirinka of Eastern Amhara to select the best performing varieties, in terms of biomass yield, chemical composition, haulm yield, seed yield and other agronomic characteristics of Glycine max (L.) Merrill grown under the rain- fed condition of lowland areas of Eastern Amhara in a randomized complete block design with tree replications. Twelve released soybean varieties were Afgat ,Belesa-95, Boshe , Cheri , Dhidhessa, Gishama , Gizo, Korme, Pawe-03, katta, Wegayen and Wollo were used as a treatments. The seeds were planted in 40 cm between rows and 10 cm between plants on a plot size of 3.2m*4m. Spacing between blocks and plots were 1 and 0.5m, respectively. The seed rate was 60 kg/ha and a fertilizer rate 100 kg/ha NPS was applied during seed planting. The combined analysis of variance over two years at location Jari for dry matter yield of varieties Afgat, Gizo, Pawe-03, Wogayen and Wollo were significantly higher as compared to other soybean varieties. The combined analysis across locations at Jari and Sirinka (2019-second year) showed that varieties Afgat, Gishama, Gizo, Pawe-03, Wogayen and Wollo had higher dry matter yield and varieties Gishama (3.97 t/ha), Gizo (3.60 t/ha), Pawe-03 (4.04 t/ha) and Wogayen (3.36 t/ha) had higher haulm yield as compared with other varieties. The combined analysis across locations at Jari and Sirinka (2019) showed that varieties Pawe-03(2951 kg/ha), Gizo (2862 kg/ha), Afgat (2859 kg/ha), Gishama (2654 kg/ha),Wollo (2461 kg/ha) and Wogayen (2404 kg/ha) had higher seed yield as compared with other varieties. The variety Wollo gave higher crud protein content in two locations (Jari and Sirinka) .Therefore, varieties Afgat, Pawe-03 and Wollo were recommends for the given areas of Jari , Chefa, Sirinka and could be produced in similar environments for the best of produced optimal amount of dry matter, haulm and seed yield and good protein supplement for production of ruminants.Thus, further researches will be needed to investigate on the utilization of livestock.

Christmas Island

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.

Loam Soil

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.

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.
