Answer:
(Note that we'll focus on grain production as an indicator of how we are doing in food production because grains supply almost more than half of humans' intake of calories and protein directly, because grain is often used to feed livestock (which consumed ~40% of global corn production alone as of 2010 -- nevermind livestock's consumption of global soy, which was about 80% as of 2010 [Vital Signs 2011]) and collectively, these two (grain and livestock) provide about 80% of the world's food supply. Further, about half of the global crop acreage is planted to grains. Thus, we use grain production as a surrogate for production trends in other agricultural commodities as well. Corn, wheat and rice constitute about 85% of the total global grain production and, amazingly, rice alone provides about 20% of humanities caloric intake [Science 18 July 2008].)

Explanation:
Limitation of Water Transport: -Water transport has the following limitations.
1. The depth and navigability of rivers and canals vary and thus, affect operations of different transport vessels.
2. It is a slow moving mode of transport and therefore not suitable for transport of perishable goods.
3. It is adversely affected by weather conditions.
4. Sea transport requires large investment on ship and their maintenance.
5. It has high maintenance costs for ship and takers as it requires constant repairs and painting of ships.
Explanation:
The good quality seed has high return per unit area as the genetic potentiality of the crop can be fully exploited. Less infestation of land with weed seed/other crop seeds. ... Minimization of seed/seedling rate i.e., fast and uniform emergence of seedling. They are vigorous, free from pests and disease.
