On multiple occasions they would stop at at negative number. This indicates an unreliable scale as the weight should never fall below zero grams. Furthermore, many of the same type of beans seemed to be different sizes (indicating different weights). Each bean of the same type should be the same weight. If the beans aren’t of a uniform weight, the mass of a group of ten brown beans could vary depending on what beans were weighed.
Alternately arranged leaves are pinnate, with a single terminal leaflet (pinnae) at the end. Flowers small, greenish yellow in compact fascicles of racemes, at the end of the leafless branches. Drupes, reniform, produced in clusters from the end of leafless branches Flowers are unisexual, greenish, the male in compound and female in simple racemes. Sepals 4, about 1mm long, broad ovate. Petals: 4, 2 mm long, oblong, green yellow.
This study focusses on green beans (or snap beans, Phaseolus vulgaris) and peas (Pisum sativum) harvested for their fresh pods intended for export. Both are member of the legume family. In what follows a concise overview is provided on their origin, phylogeny, physiology, ecological requirements and cultivation. Illustrations and tabulated summaries of the characteristics of these crops are present in ANNEX Nmbr. First an outline is given on the legume family and biological nitrogen fixation.
The aspen-like simple leaves are alternate and deciduous, broad rhombic to ovate, 3-8 cm long and 3-6 cm broad, and have a flat margin. Leaf bases are broad rounded, and the leaf blade terminates in a regularly tapering tip. The upper leaf surfaces are intermediate to dark green, and the lower to some extent paler. Leaf veins are yellow and evident on both sides. Petioles are generally 2-5 cm long, with 2 enlarged glands on the upper side instantly below the leaf blade.
The test plants used in the study were cabbage (Brassica oleracea), palak (Spinacia oleracea) and amaranth (Amaranthus spinosus), were used as test crops. Individual crop seedlings/ seeds were planted/sown in plastic pots containing a soil, sand and compost mixture (1:1:1 ratio). The compost tea treatments were imposed twice a week as foliar sprays. While palak and amaranth plants were harvested on the 40th day of planting, cabbage plants were harvested on the 50th day of planting and plant growth parameters/dry weights and nutrient contents were estimated. The shoot and root lengths of individual plants were measured and the plants dry weights were recorded after oven drying at 70˚ C. In the case of cabbage the number of leaves was also recorded.
The plant height ranges from 30-60 cm. One or two pairs of leaves form a flat rosette. They are entire, bright green, toothed and somewhat hairy on the upper surface. The lower leaves are clustered, ovate, ciliated and have rounded tips. The upper leaves are smaller, lance-shaped, opposite and attached directly to the stem.
Results showed that combination of 2, 4-D and BAP at the level of 2.0 and 0.5 mg/L was effective in callus production from nodal explants whereas no callus formation was observed from leaf explants. The organogenic callus of Trigonella foenum graecum produced multiple shoots in the MS medium amended with IBA and NAA 3.0 and 1.0 mg/L and roots amended with IAA and IBA 3.0 and 2.0 mg/L respectively. Compact callus,
We can calculate material removal rate as the volume of material removed divided by the time taken to cut. The volume removed is the initial volume of the work piece minus the final volume. The cutting time is the time needed for the tool to move through the length of the work piece this parameter strongly influences the finishing grade of the work piece. Where, Q = MRR (mm3/min), ae = Radial Depth (mm), ap = Axial Depth ( mm), vf = feed rate (mm/min). Machining Time (min): Power Consumption(kw) Tool Life
