Medieval rice farmers in Japan produced about 88 bushels of rice per acre. With today's farming methods as much as 241 bushels per acre are being reported.
150*40 kgs per acre
There's too many variables here to be able to answer this question. However, just for example, the US average yield from all states of all barley types for the period from 2006 through 2011 is 66.7 bushels per acre, according to the USDA.
World average - about 4 tonnes per hectare, world record - about 10. Yield is complicated by the fact that 2 crops per year is common, and 3 are possible under ideal weather and field conditions. Crop scientists estimate a realistic maximum for the "perfect" hybrid variety at over 20 tonnes per hectare.
The U.S. average yield for 2010 was 46.6 bushels/acre or 2.92 tonnes/hectare. The figures for 2011 are slightly lower, at 43.0 bushels/acre or 2.89 tonnes/hectare. According to the US Department of Agriculture, the US average soybean yield for the period 2006 through 2011 was 42.22 bushels per acre.

The top 20 countries have a yield of over 37 bushels (of 60 pounds each) per acre, or 2.3 tonnes per hectare.The U.S. average yield for 2010 was 46.6 bushels/acre or 2.9 tonnes/hectare.The best country, Turkey, produced an average of 58.7 bushels/acre or 3.7 tonnes/hectare.The record belongs to a farmer in Missouri who produced an average of 100 bushels/acre over a 300 acres plantation in 2010, and reached 160 bushels/acre on a specially irrigated field.Roughly 50, but it depends on the variety and environmental factors
There are four roods per acre.
About 2.88 metric tons per hectare, according to the USDA.
How many kilograms of what?
The number of rice plants that can grow in one acre varies based on the planting method and rice variety, but typically, around 100,000 to 200,000 rice plants can be cultivated per acre. This estimate assumes a standard spacing of about 6 to 12 inches between plants. Factors such as soil quality, water availability, and farming practices can also influence plant density.
There are around 40 guntas per acre, or 40 guntas in one acre.
