In a study conducted from 1991 to 1994 in Japan, rice Koshihikari was cultured under dense (25 hills/m2) and sparse (17 hills/m2) planting with a low supply of agricultural chemicals and with continuous application of farmyard manure (FYM) or chemical fertilizer (CF). Grain yield under dense planting was not significantly different from that under sparse plating when FYM was applied without CF, but was higher in the former than in the latter when FYM was applied together with a small amount of CF or only a small amount of CF was applied. This is due to the higher number of ears under dense planting.
