Abstract

The straight fertilizers are no doubt, important and easily available fertilizer source of nutrients which can meet the nutrient requirement of plants but their low availability to crop due to leaching and other losses leads to low yield. Therefore, it will be advisable to optimize the use of briquette fertilizers for getting high yields of better quality and keeping the cost of production at sustainable level. The information on nutrient requirements of the crop to be supplied through straight fertilizers is available. However, the information on requirement of nutrients in rice established by comparing different fertilizer sources is lacking. An attempt has been made here to review the effect of different fertilizer sources on growth and yield of rice.
