The effect of sowing time and sowing rate on the duration of developmental phases and growth period of rice varieties

Today, with the world’s growing population, global climate change, rising temperatures, increasing rainfall in some areas, and contrarily, severe droughts in some areas, it is becoming increasingly difficult to grow abundant and high-quality farming crops. This means that the issue of food security will become more complicated in the future. One of the priorities in solving this problem is to modernize the agricultural sector by using intensive agro-technologies in the cultivation of agricultural products. Due to the fact that the length of the day in the climatic conditions of our country is different, very short and very cold in winter, and very hot and extremely long in summer, paddy is naturally adapted to spring planting and ripening in autumn (to make offspring). In the second half of April, when rice planting begins, the length of the day is around 13,5 hours, with the longest day being 15,1 hours on June 20-22 and 12,5 hours in mid-September when rice is harvested.
