Abstract

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 Crop Research Institute (CCRI) Pirsabak, Distract Nowshera KP, Pakistan during Kharif 2016. To study the effect of different phosphorus (P) sources and their ratios on maize yield and yield components, an experiment was carried out in a Randomized Complete Block Design (RCBD) with three replication. The treatments consisted of sole application of Farmyard Manure (FYM), Poultry Manure (PM) and Diammonium Phosphate (DAP), 75% FYM+25% DAP, 50% FYM+50% DAP, 75% PM+25% DAP, 50% PM+50% DAP and a control treatment with no P fertilizer. Phosphorus was applied at the rate of 100 kg ha-1 from different sources in different ratios. The results indicated a significant effect of different 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, 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 inorga nic 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.

Highlights

Maize (Zea mays L.) is one of the important cereal crop its ranks 3rd in Pakistan after wheat and rice
It is apparent from various investigations, reusing and expansion of mechanical and agrarian squanders to soil may improve the productivity of connected and local supplements required by harvests
Amujoyegbe BJ et al Found most astounding grain yield and biomass of maize and sorghum with the consolidated use of inorganic compost+poultry excrement pursued by inorganic manure [14]

Summary

Introduction

Maize (Zea mays L.) is one of the important cereal crop its ranks 3rd in Pakistan after wheat and rice. Non-customary squanders like poultry excrement and press mud from the sugar industry are of concern and should be overseen in ecological point of view It is apparent from various investigations, reusing and expansion of mechanical and agrarian squanders to soil may improve the productivity of connected and local supplements required by harvests. Amujoyegbe BJ et al Found most astounding grain yield and biomass of maize and sorghum with the consolidated use of inorganic compost+poultry excrement pursued by inorganic manure [14]. Hussain A et al Prescribed that natural issue alone with manufactured manures could be useful for upgrading stale wheat grain yield, prudent and efficient utilization of the current land, supplement composts application, budgetary assets and reusing of natural squanders under field conditions is unavoidable [16]. Keeping in view the importance of phosphorus and the problem of the high price of chemical fertilizer, the present study was conducted to evaluate the effect of different phosphorus sources and their ratios on yield and yield components of maize under the climatic condition of Nowshera
