How does spacing affect plant growth?
Each garden plant has specific spacing requirements for optimal growth. Spacing is determined by the species of the plant and by soil fertility. Overcrowded plants grow poorly. Plants spaced too far apart don’t produce the total yields that they could if spaced more closely.
How do you space a groundnut?
Farmers are advised to sow groundnut seeds in rows and one seed per hole with the right spacing. For groundnut varieties which grow upright farmers should plant Serenut 6R, the spacing is 45cm by 7.5cm and those which spread on the ground as they grow are spaced 45cm by 10cm.
Why spacing is important in crops?
Spacing is important as it determines plant population hence the final desired yields. Appropriate row spacing makes more efficient use of light leading to faster canopy establishment, thus reducing soil moisture evaporation and weed growth.
How do you increase the yield of peanuts?
The fertilizers and manures can be broadcasted uniformly in the field. Micronutrients play a vital role in plant growth. Application of born at 3-4 kg/ha during land preparation and zinc at 10-20 kg/h once in three years has found to be effective to increased yields of groundnut.
What is the effect of spacing on crop yield?
The plant grown under wider spacing received more nutrients, light and moisture around each plant surrounding compared to plants of closer spacing, which is probably the cause of better performance and yield of individual onion in wider spacing.
Does spacing of seeds affect the growth of seed?
The wider planting space will increase the availability of nutrients and water for individual plants so that the growth of the plant increases [11]. Plant spacing adjustment which are too close will cause the availability of nutrients and water to be limited, causing the growth of plants to be inhibited [12][13].
Which fertilizer is best for groundnuts?
Among the available nitrogen fertilizers, ammonium sulfate is preferred for the groundnut crop because of its sulfur content (24%). It can be used in both rain and irrigation. Also in top dressing, it can be used before or after irrigation when the soil is in good condition.
How many months do groundnuts take to mature?
Groundnuts usually require a minimum of 100 to 150 days from planting to maturity, depending on the variety planted. Flowering continues over a long period and pods are in all stages of development at harvest.
Why proper spacing is important?
It is easy for disease to spread from one plant to another if the plants are growing on top of one another, so plants growing too closely together are not as healthy as plants with enough space. Overcrowding also reduces air circulation, which helps prevent disease. This makes your plants much more likely to get sick.
What happens when a plant doesn’t have enough space?
A pot that is too small can constrict the plant’s roots, especially plants with big roots. The roots can get packed in without having enough room to spread out. If this happens, the plant’s growth may slow down. You might also have issues with the plant tipping over because of the extra weight in comparison to the pot.
What is the best fertilizer for groundnut?
Among the available nitrogenous fertilizers, ammonium sulphate is preferred for groundnut crop because of its sulphur content (24%). It can be used in both rainfed and irrigated conditions.
What are the fertilizer requirement of groundnut?
The recommended fertilizer dose of 17:34:54 kg NPK per ha for groundnut and 40:20:20 kg NPK per ha for sunflower was applied as per the treatment schedule. Fertilizers were applied in the form of Urea (46% N), Super phosphate (16% P2O5) and Muriate of potash (60% K2O) for both the crop.
Why is seed spacing important?
If the plants are too far apart, the space will be used inefficiently. Furthermore, there will be a greater opportunity for weeds to come up between the plants and compete with them for light, water and nutrients – or add to the work required for cultivation.
What happens if plants grow too close together?
Plants that grow too close to each other compete for the same sunlight, water and soil nutrients. The first effect seen is competition for light. Overcrowded plants begin to grow upward to receive light, rather than developing a fuller, bushier silhouette.
Is urea good for groundnuts?
Urea is very popular and commonly used in groundnut. It can be used as basal-dressing in rainfed as well as irrigated conditions, for while top-dressing in rainfed, as well as irrigated conditions, but while top-dressing it should be applied at optimum soil moisture followed by harrowing.
Do we apply fertilizer in groundnuts?
Groundnut crop plant is a legume that can fix nitrogen in the soil is perceived by many researchers as a crop that does not require nitrogenous fertilizers for proper growth and development. In poor or marginal soil, it needs nitrogenous fertilizers for proper growth, development, and yield production.
When should I fertilize my groundnuts?
A good strategy for nitrogen management in Groundnut cultivation is to apply a starter dose of 15 to 20 kg N / ha and encourage nitrogen fixation through Rhizobia inoculation to meet the nitrogen requirements of plants. Be encouraged Nitrogen starter dose is applied with phosphorus and potassium just before sowing.
How do you fertilize groundnuts?
If you apply fertilizers by hand or by using a scoop, you must give fertilizer to each plant, and the same amount to each plant. After you have spread your fertilizer, work it Into the soil with a hoe. Always cultivate a few days after applying fertilizers.
What happens if plants are too close together?
The Dangers Of Planting Too Close Together If you plant flowers too close together, the plants get stressed and are prone to diseases, Kole says. If air can’t properly circulate and the plants can’t dry out between waterings, fungus sets in. Roots can rot. And once plants are weakened from stress, insects move in.
How does overcrowding affect plant growth?
Overcrowding can compromise the space that plants need for root growth. It can also decrease the amount of nutrients that any of the crowded plants can absorb from the soil, causing developmental problems in all of the plants.
What is the seed rate and spacing of groundnut?
The seed rate and spacing of groundnut: The seed rate depends on the variety (Spanish, Valencia, or Virginia), runner or bunch type, the seed mass, and germination rate of the seed-lot. The recommended population for bunch varieties is 330 000 plants ha -1 (about one plant per 30 x 10 cm).
How to break dormancy of spreading groundnut?
The aqueous extract from the seeds of bunch groundnut can break the dormancy of spreading variety when the seed of the spreading variety is soaked in the extract. Treating the kernels with ethylene chlorhydrin (0.7%) can break the dormancy.
What is the special feature of groundnut?
The special feature of groundnut is that the fruit begins as a fertilised flower above ground but pod and seed mature in the ground. A system of staging the groundnut plant was proposed by Boote (1982).
How do you grow groundnut?
Groundnut farming. Groundnut is perfectly grown in well-drained sandy loam or sandy clay loam soil. Deep well-drained soils with a pH of 6.5-7.0 and high fertility, are ideal for groundnut. Optimum soil temperature for good germination of groundnut is 30°C. The low temperature at sowing delays germination and increases seed and seedling diseases.
