Red spinach (Amaranthus gangeticus) is one of the most popular vegetables because of its high nutritional value and easy cultivation. Efforts to increase the production of red spinach are to fertilize to meet the needs of both macro and micronutrients. This study aimed to determine the effect of ZA fertilizer dose on the growth and yield of red spinach. The environmental design used was a non-factorial, completely randomized design with four replications. The factors tested were the dose of ZA fertilizer which consisted of 6 levels, namely: without ZA fertilizer (D0); 0.4 gr/polybag (D1); 0.8 gr/polybag (D2); 1.2 gr/polybag (D3); 1.6 gr/polybag (D4); 2 gr/polybag (D5). The data obtained were analyzed using analysis of variance, and if the results were significantly different, the BNT test was continued at a 5% level. The growth and yield of red spinach showed significant differences due to the ZA fertilizer dose treatment. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest plant height, the number of leaves, and leaf area of red spinach at 14, 21, and 28 days after planting. The ZA fertilizer dose treatment of 1.2 g/polybag (D3) resulted in the highest wet and dry weight plants of 49.15 and 4.38 grams, respectively. The ZA 1.2 gr/polybag dose is the ideal dose to increase the productivity of red spinach.Bayam merah (Amaranthus gangeticus) termasuk sayuran penting yang disukai masyarakat karena bernilai gizi tinggi dan mudah pembudidayaannya.

Four Levels

Wheat was grown at a density of 120 plants m-2 in deep pots of soil in two artificially illuminated growth cabinets. One cabinet was left at ambient CO2 levels and the other enriched by 250 volumes per million (vpm). Four levels of growth-restricting water supply were imposed. Responses by the two cultivars used (Gabo and WW15) did not differ appreciably in terms of the mature crop dry-weight parameters examined. Comparison of the crop responses to water supply indicated sufficient correspondence between generalized field behaviour and cabinet behaviour to justify tentative interpretation of the results in terms of possible response of water-limited field wheat crop yields to the globally rising level of atmospheric CO2. The less water made available to the crop the less was the absolute response of grain yield to CO2 enrichment, but the greater was the response relative to the control yield. Under extreme aridity (about 100-120 mm crop transpiration overall), the data implied infinite relative enhancement of yield due to CO2 enrichment, because it allowed some grain growth where none occurred without extra CO2. The absolute yield enhancement was equivalent to 5-13 kg ha-1 per 1.2 vpm increment of atmospheric CO2 concentration. The level of CO2 in the global atmosphere is currently rising by about 1.2 vpm year-1. The higher temperature at which the crops were grown (19°C), relative to average field conditions in many wheat areas, may influence this interpretation.

Bambara groundnut (Bogor groundnut) was an alternative food crops having high nourishing, better taste and bigger size nut than the soy beans and peanuts. To meet the need for food and industrial needs, the program to increase production of Bogor groundnut was required, one of which is the use of peat as a growing medium using the technology of mixing peat and mineral soil. The research objective was to obtain a mixture of peat with mineral soil and dolomite lime dose suitable for the highest growth and yield of Bogor groundnut.  This study was conducted in May 2015-September 2015 in the Greenhouses of Faculty of Agriculture, University of Bengkulu. The experiment was arranged in a completely randomized design (CRD) with two treatment factors and three replications. The first factor was soil mix of peat and mineral soil (G0: 100% peat + 0% mineral soil; G1: 75% peat + 25% mineral soil; G2: 50% peat + 50% mineral soil; G3: 25% peat + 75% mineral soil) and the second factor was the dose of dolomite (D0: without lime dolomite; D1: 3 ton ha-1 and D2: 4 ton ha-1). The results showed that the response of biomass dry-weight to a mixture of peat with mineral soil was influenced by the dose of dolomite, but there was no interaction on other variables.  Treatment of a mixture of peat 100% alone was capable of generating the highest number of leaf, biomass fresh- and dry-weight.  Bogor groundnut plants showed the same response to the dose variation of dolomite lime.Keywords: Bogor groundnut, peat, mineral, dolomite
