%P(as received)= 5.8 ± 0.008% and %P(dry) = 5.95 ± 0.008%. While, %P2O5 (as received)= 6.63 ±0.008% and % P2O5 (dry)= 6.80 ±0.008%. This shows that the fertilizer also has macronutrients other than water and phosphorus which can be useful for plant growth. This experiment is successful since the results obtained
The crop occupies 12.1% of total pulses area and 8.8% of total pulse production in India with an average national productivity of 518 Kg/ha. Because of its relative tolerance to drought, a short life cycle (75-90 days) and the ability to fix atmospheric nitrogen, it is cultivated as a component in various cropping systems, chiefly with rice and wheat (Kaewwongwal et al. 2015). Soil amendments that increase soil fertility and plant productivity can be very useful for crops. An improved crop yield by inoculation with a phosphate solubilizing fungal strain has been observed in many field studies.
Introduction Aim: To compare the effectiveness of compost and earthworms on the germination and yield of a spinach crop. Motivation: Fertilisers are mixture of chemicals that add nutrients to the soil to establish better yielding crops (Berger, 2013). Though these products have proved to provide many beneficial aspects to the agricultural sector, they have many negative environmental consequences. Fertilisers contain many substances, including mostly potassium, phosphorus, sulphur, calcium, magnesium and nitrogen. These substances, when they accumulate in the soil, can have harmful side effects on the environment and subsequently on the productivity of crops (Vimpany and Lines-Kelly, 2004).
The PH of the soil: Soil PH is simply a measure of how acid or alkaline the soil is on a scale of 1-14 , and soil acidity or alkalinity (soil pH) is important because it influences how easily plants can take up nutrients from the soil; thus indicating the health of the soil. from 6.0 to 7.5. Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available. When pH exceeds 7.5, iron, manganese, and phosphorus are less available. Macro-organisms found in the soil: If a lot of worms or other organisms are found in the soil, it will indicate that the soil is most probably healthy enough for the access of people as it is not to acidic or alkaline to contain life because Earthworms need moisture and nutrients.
droughts, floods and extreme temperatures), pests(e.g. insects and herbicides), diseases and chemical fluctuations. Genetic engineering also provides foods that have a highly reduced spoilage, have an improved nutritional content, ripen faster, larger in size, and more ‘juicy’ or appetizing than their naturally occurring varieties. For example since cotton seed oil, soybean, canola and corn are in high demand, they have been genetically modified for better nutritional content, pathogen and herbicide resistance. Further, unlike selective breeding genetic engineering allows more control over genetically modified organisms and more understanding of genetics or
With the many advantages and disadvantages, which is better; GMO or Organic Food? Genetically modified organisms as we know it today is considered to have only negatives, but GMOs actually contain many positives. Such properties with crops like the conservervation of land and water resources are all possible because of genetic modifications. Crops today can be engineered to produce higher harvests from the same croplands. In some cases, the crop can double its production when the transition from traditional crops to GMO crops is completed by local farmers.
Organic farming benefits food production without destroying our environmental resources, ensuring sustainability for not only the current but also future generations. Cultivation While their conventional counterparts may sow by direct drilling of seed into herbicide treated soils, organic farmers are usually at least partly dependent on cultivation to remove weeds prior to sowing. In contrast to cultivation, direct drilling does not mechanically disrupt soil structure and removes the risk of exposed soil being lost to wind or water erosion. This is a valid argument where farmers are working marginal quality soils. However, the structure of agrichemically-deadened soils is weakened by the corresponding loss of soil life and thus unable to maintain its integrity under occasional cultivation.
Effect of different physical conditions on nitrogen fixing bacteria from rhizosphere Hypothesis: Rhizospheric Nitrogen fixing bacteria show optimal growth at PH: 6-7, Temperature: 30 °C and Salinity level: 0.005 – 0.010M NaCl INTRODUCTION: There is a huge bacterial diversity in rhizospheric soil. Gram-negative, non-sporulating baccilli which respond to root exudates are predominant in the rhizosphere (Pseudomonas, Agrobacterium). While Gram-positive bacilli, Cocci and aerobic spore forming bacteria like Bacillus and Clostridium are rare in the rhizosphere. The most common genera of bacteria are Pseudomonas, Arthrobacterm Mycobacterium, Flavobacter, Cellulomonas, Agrobacterium, Alcaligenes, Azotobacter,
Abstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary
The research also showed that the GM foods have high nutrients and contain more minerals and vitamins compared to the traditional crops. Key et (2008) GM technology offers a way to alleviate some of these problems by engineering plants to express additional products that can combat malnutrition. The authors trying to say that genetically modified crops can produce more nutrients that are needed by the human body. Whitman (200) stated that genetically modified crops are drought/salinity tolerant. These plants can withstand long periods of drought or
