Abstract

(Zea mays L.) is one of the important staple foods of not only India but the world. Area under maize cultivation and its production both has been steadily increasing in recent past in Bihar. Currently farmers are opting for intensive cultivation which is causing very adverse effect on soil health. To improve productivity and manage soil health, use of these nutrients is very essential. Major nutrients NPK are required for growth and development of the Maize crop. But majorly, nutrient requirements vary depending on the growth stage of Maize. At different growth stages, different sets of nutrients are required. Zypmite is a Soil Conditioner, containing secondary nutrients sulphur, calcium, magnesium along with micro-nutrients zinc and boron.  To study the effect of Zypmite Plus a slow releasing soil conditioner on Nutrient Uptake in Maize, an experiment was conducted at Bhola Paswan Shastri Agricultural College, Purnea with 4 treatments  ( T1 = Control (without RDF), T2 = RDF (N:P:K:120:60:40), T3 = RDF (N:P:K:120:60:40)+ Z1 (125 kg ha-1) & T4 = RDF (N:P:K::120:60:40)+ Z2 (187.5 kg ha-1) and five replications. Zypmite, when applied alongwith recommended dose of fertilizer had an impact on maize crop in both the years of study. Doses of 125 kg/ha of Zypmite plus (50 kg/acre) and 187.5 kg/ha of Zypmite plus (75 kg/acre) alongwith recommended dose of fertilizer were performing better than recommended dose of fertilizer. Soil nutrient availability was also improved by using Zypmite plus for both macro nutrients and micronutrients. Total nitrogen, phosphorus and potassium uptake is the product of concentration of nutrient to the dry matter. Data pertaining to the total nitrogen, phosphorus and potassium uptake for the two years study (2019-21) shows that total nitrogen nitrogen, phosphorus and potassium uptake was significantly higher in all the treatments (RDF, RDF+Z1, RDF+Z2) over the control (without RDF). The nitrogen, phosphorus and potassium uptake were significantly highest with the treatment RDF+Z2 but at par with the treatment RDF+Z1 for maize crops. The increase in the nitrogen, phosphorus and potassium uptake varied from 71-112%, 104-172% and 76-121% for maize crop.
