Effects of Time of Second Nitrogen Application on Growth and Development of Rice Plants

Pot and field experiments were conducted to study the effect of different times of second nitrogen (N) application on growth, yield, protein content of grain and milling quality of rice (Oryza sativa L variety Seberang). Second N application was carried out at three-day intervals from 39 to 78 a...
