Effects of mycorrhiza and plant growth promoting rhizobacteria inoculants on rice crops in Northern India

Mutualistic root microorganisms such as arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) can ameliorate plant nutrition through an extended extra-radical hyphal network and by nutrient mobilisation. Running under the Indo-Swiss Collaboration in Biotechnology (ISCB), our project focuses on the integration of AMF and PGPR as biofertilisers in wheat-rice and wheat-black gram systems

RESPONSE OF VEGETATIVE GROWTH OF PULLE PLANTS (Rauvolfia serpentina Benth.) TO THE ORGANIC NUTRITION TREATMENT AND WATER AIR

This research aims to study how far the effect of water stress and organic nutrition types on the pule pandak’s growth. This research was conducted in BPP Mondromino, Village Pokoh Subdistrict Wonogiri, Regency Wonogiri. This research employed Completely Randomized Design consisting of two treatment factors. The first factors : water stress, consists of 3 levels (100% field capacity, 60% field capacity and 30% field capacity). The second factors : organic nutrition (20 ton/ha dose), consists of 4 types (without nutrition, cow nutrition, goat nutrition and compost nutrition). Interaction of water stress and organic nutrition treatments affects high significantly the number of leaves per plant, plant height, and root length, but affects non significantly the leave width and leave weight. The result of observation on 5th month after plant shows that the water stress treatment affects high significantly the number of leaves per plant, leave width, leave weight, plant height, and root length. The result of organic nutrition treatment affects high significantly the number of leaves per plant, leave width, leave weight, plant height, and root length. Interaction of water stress and organic nutrition treatments affects high significantly the number of leaves per plant, leave width, plant height, and root length

Enzyme Dynamic in Plant Nutrition Uptake and Plant Nutrition

Soil contains enzymes, constantly interacting with soil constituents, e.g. minerals, rhizosphere and numerous nutrients. Enzymes, in turn, catalyse important biochemical reactions for rhizobacteria and plants, stabilize the soil by degrading wastes and mediate nutrient recycling.The available enzymes inside soil could originate from plants, animals or microbes. The enzymes that are produced from these organism could exhibit intracellular activities, at the cell membrane, interacting therefore with soil and its constituents, or extracellularly (so freely available). Therefore, vis-à-vis to plant nutrition, the (extra or sub) cellular localization has a key role. Typical major enzymes available in soil can be listed as dehydrogenases, hydrogenases, oxidases, catalases, peroxidases, phenol o-hydroxylase, dextransucrase, aminotransferase, rhodanese, carboxylesterase, lipase, phosphatase, nuclease, phytase, arylsulphatase, amylase, cellulase, inulase, xylanase, dextranase, levanase, poly-galacturonase, glucosidase, galactosidase, invertase, peptidase, asparaginase, glutaminase, amidase, urease, aspartate decarboxylase, glutamate decarboxylase and aromatic amino acid decarboxylase. An interesting strategy for improving the nutritional quality of the soil would be to inoculate microorganism to soil while giving attention to mineral or other compounds that affect enzyme activity in soil. Since, some elements or compounds could show both activation and inhibitory effect, such as Fe, Na, etc. metals, the regulation of their bioavailability is crucial

Bedding plant nutrition

1979 Fall.Covers not scanned.Includes bibliographical references.Three nutrition experiments were conducted to determine the nitrogen, phosphorus, and potassium nutrient levels necessary to obtain quality bedding plant growth. A soil medium of equal parts (by volume) Fort Collins Clay Loam, Canadian peat moss, and perlite, and soilless medium of equal parts (by volume) Canadian peat moss and vermiculite were used in all experiments. Pelargonium hortorum 'Sprinter Scarlet' and Petunia hybrida 'Candy Apple' seedlings were grown in the 2 media and watered with 5 nutrient solutions containing varying ratios of NO3-:NH4+, each resulting in a total NO3- plus NH4+ concentration of 15 meq 1-1. There were no significant differences in height, fresh and dry weights, or number of vegetative breaks in soil-grown plants due to the N sources. Plant growth in the soilless medium was substantially reduced as the proportion of NH4+ increased above 50%. Plant quality of Pelargonium hortorum 'Sprinter Scarlet' and Petunia hybrida 'Candy Apple' were also evaluated in the 2 media when watered with 12 nutrient solutions containing 4 nitrogen concentrations (half NO3-, half NH4+) of 7.0, 11.5, 14.0, and 17.5 meq 1-1, and 3 potassium concentrations of 2, 4, and 6 meq 1-1. Potassium concentrations above 2 meq 1-1 had little or no affect on plant growth in either media. Increasing nitrogen rates caused increased plant height, and fresh and dry weights. The 7.0 meq 1-1 nitrogen-grown plants showed signs of nitrogen deficiency. Maturity, in terms of flowering and number of vegetative breaks, was not affected by the nutrient regime. Optimum plant growth in both media was produced with 11.5 meq 1-1 nitrogen and 2 meq 1-1 potassium treatment. Seedlings of Pelargonium hortorum 'Sprinter Scarlet', Petunia hybrida ' Pink Magic ', Impatiens holstii 'Elfin Red', and Tagetes patula 'Goldie' were grown in the 2 media with 4 phosphorus treatments consisting of 0 kg m-3 treble superphosphate preplant plus a continuous feed using 25-0-25 (1.408 meq 1-1 H2PO4-, 200 ppm P2O5), and 0, 3, and 6 kg m-3 treble superphosphate preplant plus a continuous feed of 20-20-20 (1.408 meq 1-1 H2PO4-, 200 ppm P2O5). All species, except impatiens, showed increased growth with increased phosphorus levels; impatiens gave little or no response to phosphorus treatments. Flowering time of all species was unaffected by the treatments. The 3 kg m-3 treble superphosphate plus a continuous feed of 20-20-20 (1.408 meq 1-1 H2PO4-, 200 ppm P2O5) gave the best plant response in both media

Effect of Some Nutrient Applications on Plant Properties in Organic Strawberry Production

This study was conducted with the “Camarosa” strawberry cultivar at the Egirdir Horticultural Research Institute between 2004 and 2006. In these experiments, the impact of some nutrition applications upon plant development in conventional and organic production has been analyzed. The planting has been performed with frigo plants in the third week of July and black plastic mulch was used for mulch system and dripping method was used for watering system in the experiment. When evaluating the data of two years statistically according to plant width, plant stem number, leaf number and root length, the difference in both applications and years has given importance

Controlled Ecological Life Support System: Use of Higher Plants

Results of two workshops concerning the use of higher plants in Controlled Ecological Life Support Systems (CELSS) are summarized. Criteria for plant selection were identified from these categories: food production, nutrition, oxygen production and carbon dioxide utilization, water recycling, waste recycling, and other morphological and physiological considerations. Types of plant species suitable for use in CELSS, growing procedures, and research priorities were recommended. Also included are productivity values for selected plant species
