Maize Yield Response under Various Phosphorus Sources and their Ratios

Waqar Ali

Improper use of fertilizers and its ratio is one of the main reasons for low productivity; therefore balance fertilization is required to maintain crop production and improved soil fertility. Therefore the experiment was carried out at Cereal phosphorus sources on days to tasselling, days to silking, days to maturity, plant height, grains ear-1, grain yield, biological yield, and harvest index, whereas the emergence m-2 was found non-significant with different P sources.The combined use of organic and inorganic P sources delayed tasselling, silking and maturity. Plant height, grains ear-1, at the rate of 100 kg ha-1 from different sources in different ratios. The results indicated a significant effect of different control treatment with no P fertilizer. Phosphorus was applied biological yield, grain yield, and harvest index was also higher with the addition of P from both sources as compared with the sole application of organic or inorganic fertilizer. The combined application of organic manures 50:50 (FYM or PM) and inorganic fertilizer (DAP) performed better as compared to the rest of the ratios and produced higher yield and yield components.
