How are cultivation practices and crop yield related to weather?
Cultivation practices and crop yield are related to weather conditions. Because weather conditions such as drought and food situations are unpredictable, varieties that can be grown in diverse climatic conditions are useful.
Why is crop yield important in agriculture?
Crop yield is the measure of crop produced per area of land. It’s an important metric to understand because it helps us understand food security and also explains why your tomatoes can cost more one year and then less the following year.
What are the practices used for higher yield of crops?
One of the best ways to maintain the soil in good health is to practice crop rotation, among others. Alternating plants on a given field plot prevents soil exhaustion and breaks pest cycles, which will result in better agricultural output and, therefore, will increase the average crop yield per acre.
What was the impact of increased crop yields?
What was the impact of increased crop yields? The general population rose dramatically. New farming methods developed at a rapid rate. Farmers were able to grow many different grains.
How are cultivation practices and crop yield related to each other describe any two factors for which variety improvement is done?
The factors for which variety improvement is done are: (i) Higher yield: To increase productivity of the crop per acre. (ii) Improved quality: The quality of crop products vary from crop to crop. (v) Wider adaptability: It allows the crops to be grown under different climatic conditions in different areas.
How is crop yield calculated?
To estimate crop yield, producers usually count the amount of a given crop harvested in a sample area. Then the harvested crop is weighed, and the crop yield of the entire field is extrapolated from the sample. For example, a grain of wheat yielding three new grains of wheat would have a crop yield of 1:3.
How can crop growth be improved?
Crop genetic improvement, by GM or conventional approaches, is only one of many methods that can be used to improve crop performance. Others involve improvements in farm practices, irrigation, drainage, and herbicide, pesticide and fertiliser use.
What are the three main stages involved in crop yield improvement?
This was achieved by various practices involved in farming and they are divided into three stages they are: Crop variety improvement – Choosing right seeds for planting. Crop production improvement – Cultivating of the crop plants….They are:
- Mixed cropping.
- Inter cropping.
- Crop rotation.
How does temperature affect crop yield?
The effects of increased temperature exhibit a larger impact on grain yield than on vegetative growth because of the increased minimum temperatures. These effects are evident in an increased rate of senescence which reduces the ability of the crop to efficiently fill the grain or fruit.
What caused an increase in crop production?
The pressure to increase crop production in many countries, has resulted in the expansion of land area dedicated to agriculture and the intensification of cropland management through practices such as irrigation, use of large quantities of inputs like inorganic fertilizers and synthetic chemicals for pest and weed …
What are the two methods of crop variety improvement?
Crop variety improvement: It can be done either by hybridisation or by introducing a gene. (i) Crop improvement by hybridisation: Hybridisation refers to crossing between genetically dissimilar plants.
What are the factors for crop variety improvement?
The factors for which variety improvement is done are: (i) Higher yield: To increase productivity of the crop per acre. (ii) Improved quality: The quality of crop products vary from crop to crop. E.g., protein quality is important in pulses, oil quality in oilseeds, preserving quality in fruits and vegetables.
How do we calculate yield?
Estimation method
- Select an area that is representative of the paddock.
- Do this 5 times to get an average of the crop (A)
- Count the number of grains in at least 20 heads or pods and average (B)
- Using Table 1 determine the grain weight for the crop concerned (C)
- Yield in t/ha = (A × B × C) / 10,000.
How is yield calculated?
Generally, yield is calculated by dividing the dividends or interest received on a set period of time by either the amount originally invested or by its current price: For a bond investor, the calculation is similar.
How do fertilizers increase crop yield?
Exogenous fertilization influences the crop yields by improving soil fertility, such as soil carbon, nutrients, and pH. Soil carbon content is the essential index for different yields (Tian et al., 2016).
How do you calculate yield per acre?
Yield (bushels per acre) equals (ear number) x (average row number) x (average kernel number) divided by 89.605* = bushels per acre.
What is the yield per hectare?
According to the crop yield data placed before the House, India’s rice yield was 2191 kg/hectare, while the global average stood at 3026 kg/hectare, while wheat is 2750 kg/hectare as against the world average yield of 3289 kg/hectare.
