Abstract:
Maize (Zea mays L.) has high growth rate, produce large quantity of organic matter, and is highly susceptible to weeds presence. An experiment comprised of two factors i.e. hybrids (DK-Garanon, Pioneer-3025, WS-666, and Pioneer-3164) and potassium ratios (Organic vs inorganic) was laid out in randomized complete block design with split plot arrangement in four replicates. Organic source of K was poultry manure (PM) while inorganic source was sulphate of potash (SOP). Potassium (K) was applied from both organic and inorganic source in different ratios to provide a total of 80 kg K ha-1. Among maize hybrids lowest weeds fresh weight, weeds dry weight with highest 1000 grains weight, biological yield and grain yield was recorded for DK-Garanon hybrid whereas more grains ear-1 was recorded for Pioneer-3164. Regarding potassium ratios, highest weeds fresh weight and dry weight was recorded in plots which received 100% K from organic source. Highest grains ear-1, 1000 grains weight, biological yield and grain yield was recorded in plots where 40% K was applied from organic and 60% from inorganic source. Integrated application of 80 kg ha-1 K in such an arrangement that 40% K is obtained from organic and 60% from inorganic source results in better yield. More study on combined use of organic and inorganic source of K is recommended to explore more its benefits.
