Then, the funnel was fixed on a cylinder and 100 ml water was added to soil in the funnel slowly. Watch glass dish was used to cover the upper surface of the funnel to avoid losing any water by evaporation. The start time of each sample was recorded to calculate the amount of collect water in the cylinder after one hour. The retained water in the soil was calculated simply (100 – the collected water in the cylinder) with considering the amount of water in the cotton or ply tissue. Water content was estimated in additional samples (100 gm) by weighting the soil samples (W1) and afterwards drying them at 105 °C (W2).
Transfer the germinated seeds into seedling trays. Mix 6 g of N-P-K (15-15-15) fertilizer with 300 g of soil. Transfer the emerged seedlings at the second-leaf stage into pots containing 5 kg of soil and place in the glasshouse. Flood the pots containing the chilli plants with water and inoculate the plants at the fourth-leaf growth stage. 3.2 Silicon treatments Both powdery silicon oxide and calcium silicate obtained from the glasshouse office in UMT are used as silicon sources in this study.
of soil was taken passing through 75 micron sieve was taken. Water was added to it to bring its moisture content to about 8% . The mould with base plate attached was weighed . The extension collar was attached with the mould. Then the moist soil in the mould was compacted in 3 equal layers, with 25 blows from the 2.6 Kg rammer on each layer.
Plant material Seeds of Artemisia vulgaris L. were surface disinfected with 10% (v/v) dettol solution (Reckitt Benckiser, Kolkata, India) for 5 min, followed by rinsing three to five times in sterile distilled water. The seeds were then surface sterilized with 0.1% (w/v) aqueous mercuric chloride (HgCl2) for 4-5 min and finally rinsed with autoclaved distilled water (three to five changes). Surface sterilized seeds were inoculated into culture flasks containing 25 ml MS medium supplemented with 10% (v/v) filter sterilized coconut water and incubated in a dark chamber for 5-7 days at a temperature of 23C to facilitate germination. Later they were transferred to photoperiodic conditions and maintained for another 28-32 days for seedling growth.
Allelopathic test: Hundred and fifty grams (150 g) of sand was placed on eight petri dishes respectively. On each dish, fifty (50) S. Alba seeds were placed, arranged in equal distance between each seed. Following that, forty five milliliters (45 ml) of H. Pilosella extract of varying suitable concentration (see table 1) was poured into the petri dishes. The number of germinated seeds was noted down every day for the next seven days. At the end of the seventh day, using a random number generator and a simple grid, fifteen seedlings were collected for stem and root length measurement from each group in order to investigate a possible allelopathic effect on the development of S. Alba
Clove is the introduced crop, due to lack of substantial variability in the existing populations it is not to reach these breeding objectives and being a perennial crop with long juvenile period (Krishnamoorthy and Rema, 1994). In search of distinct types of clove at HRS, Yercaud by Balakrishnamoorthy and Kennedy (1999). Two distinct bud variants were identified which differs in morphological and flower bud characters. One is having bolder flower buds than the normal type (king clove) and the other one is having smaller than the normal clove (dwarf/ mini
Following are the steps involved in fermentation of cucumber pickling. • Harvesting • Washing • Brining • Fermentation Harvesting: • In this method cucumbers are poured into a jar or tank and then brine solution is poured onto the cucumbers so fermentation is allowed to proceeds. Fermentation take at 18-20 C and a naturally occurring bacteria (lactobacilli) present on the cucumbers. In either case, the bacteria are halophyllic, or salt tolerant. During a storage period of about five weeks, the fermentation bacteria breakdown the sugars present in the vegetable and produce carbon dioxide.
3.4.2 Number of Days to 50% Flowering This shall be determined for sole okra and intercrop okra (at 2 weeks before sowing egusi melon, same time with egusi melon and 2 weeks after sowing egusi melon) which shall be determined from the day of planting to when half of the plant population in each plot had flowered. 3.4.3 Number of Leaves/Plant This shall be determined fortnightly by counting the number of leaves on 5 plants sampled per plot from both main plot and sub plot. 3.4.4 Plant Height (cm) This shall be determined fortnightly by measuring the height (with the aid of measuring tape) of 5 plants sampled per plot from both main plot and sub
In the face of an inadequate fertility of soil and the inability to farm using conventional methods, which soil alternative proves to be the most efficient, the most water-wise and overall best for agriculture? I plan to investigate the alternative growing mediums using a single plant type, considering the aspects of each that may be beneficial in various outcomes which lead to earth’s soil becoming unusable. I will be using compost as the control, and then six different alternatives: vermiculite, perlite, coco peat, rockwool, Jiffy’s and a mixture of vermiculite and coco peat, and I will be growing radishes. Hypothesis: My hypothesis is that while compost-soil will produce the best specimen due to its nutrients and minerals that all plants have
Before planting muskmelon, it is important to start with a clean field to prevent competition between the weeds and the crops for water, fertiliser and sunlight. Muskmelon which also known as cantaloupe is susceptible to any danger or harm such as fungal rots after harvest. These rots occur on the external surface of the fruit and spreading inwards into the fruits’ flesh. Thus, dipping melons in hot water at 52-550C for 2 minutes can effectively control fungal rots in melon. Besides, storing cantaloupes at temperature below 20C will result in chilling injury.
