What type of crop is soybean
FYM at the time of sowing proved better results. Also 25 Kg Zinc sulphate and 10 Kg Borax should be applied. In case of Kharif crop irrigation is not needed and it is grown rainfed. However during summer the crop can be grown only under assured irrigation and it needs about irrigations. The crop should be irrigated at the following critical growth stages to minimize water. Sprouting stage 2. Flowering pod initiation and bean filling stages are important from yield point of view.
At the time of sowing one deep ploughing two harrowings should be given tomaintain optimum moisture at sowing. Keep plot weed free upto 40 days by one or two hoeings, two weedings upto 40 days. Herbicides such as Toke 25, 1.
Mixed with maize, sesamum etc. The first two leaves that develop are called unifoliates, meaning that the leaf has a single flat surface, the blade, similar to the leaves of elm or maple trees.
The remaining leaves are three-bladed, or trifoliates. The place where a leaf petiole attaches to the stem is called a node. Later, flowers will develop at the nodes, between the petiole and stem, and branches also grow out from here. After the first few leaves develop, overall growth of the plant increases rapidly. If plants are spaced far apart, more side branches will grow outward to capture as much light as possible, producing a bushy-looking plant.
Plants in dense stands tend to grow upward, with few or no branches. Some soybean varieties tend to branch more than others. As new upper leaves begin to shade older, lower leaves, the lower leaves may turn yellow and fall off. This is nothing to be concerned about, since the plant is just getting rid of unproductive leaves. While the stem and leaves are growing upward, the root system is growing deeper into the soil.
At first, the plant grows a main taproot, but soon side roots branch off, and still others grow off from them. The deepest roots may reach down five feet or more in loose, well drained soil, but most of the roots are found in the upper one foot of soil. The young roots start to develop root nodules within a week after emergence if the proper nitrogen-fixing bacteria are present in the soil.
In favorable soil conditions, a couple dozen or so pea-sized nodules will develop on the upper roots of a plant. Healthy nodules will be pink or reddish inside. From 3 to 15 flower buds develop at each node of the stem.
There are two main types of soybean, depending on how flowering occurs. Varieties called indeterminate continue growing upward at the tip of the stem for several weeks after flowering begins lower on the stem. Upper nodes will not flower until later. Most commercial varieties are indeterminate.
They typically grow taller and do best in short growing seasons. A few varieties are called determinate and complete their growth in height first, then all flowers bloom at about the same time. They resemble the flowers of pea or clover, since the soybean is in the same plant family, the legume family.
The flowers are self-pollinated; that is, the flower fertilizes itself, and insects are not required to carry pollen from one flower to another. Flowering of a certain variety begins sooner when the days are shorter and later when the days are longer if the plants are grown where there is artificial light during the night, they may never flower.
Apply irrigation depending upon rainfall conditions. No irrigation required in good rainfall conditions. If necessary take second spray 10 days after first spray. Hairy Caterpillar: To control hairy caterpillar pick caterpillar manually and destroyed by crushing or putting in kerosene water when infestation is low. Blister beetle: They cause damage at flowering stage.
They feed on flowers, buds thus prevent grain formation. If infestation is observed, take spray of Indoxacarb Carry out spraying in evening hours and if necessary take second spray 10 days after first spray. Yellow mosaic virus: It is spread due to white fly. Irregular yellow, green patches are observed on leaves. Pods not developed on infected plants. Grow yellow mosaic virus resistant varieties. Pods become dry and leaves changes their color to yellow and fall of, it is sign of crop is ready for harvesting.
Harvest the crop with sickle or by hand. After harvesting, carry out threshing operation. After drying, carry out proper cleaning of seeds. Remove small size seeds, damaged seeds and crop stalks. You have successfully login. Your email and password is incorrect!
