This study was aimed to determine effects different fertilizer applications dolomite amendments on yield, quality, soil fertility after plantation post-active acid sulfate Phra Nakhon Si Ayutthaya province, Thailand. A randomized complete block design (RCBD) w...

Cotton (Gossypium hirsutum L.) and potassium (K) dynamics are not well understood particularly in soils with high K levels. Potassium is important for cotton reproductive development as it influences the number, size, weight of bolls can improve fiber quality by mitigating moisture stress. In case that soil cannot replenish solution from exchangeable reserves to meet plant demands, deficiencies...

date palm tree reaction to fertilizer is very slow, due to the trunk nutrients. this fact leads to farmer unwillingness to feed the trees. however, balance fertilizing improves vegetative growth and reduce the period for flowering. this study aimed to assess the effects of manure, chemical and organic sulfur on vegetative characteristics of ‘piarom’ date palm offshoot in a randomized complete b...
