Abstract:

The present experiment entitled “Effect of different levels of potassium on performance of Kharif maize (Zea mays L.)” was carried out at the Crop Research Centre of Tirhut College of Agriculture, Dholi under Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar during Kharif 2017. The experiment was laid out in Randomized Block Design with four replication taking variety ‘Pioneer-3377’ as a test crop. The soil of the experimental field was sandy loam in texture, calcareous in nature with pH 8.2 and low in organic carbon (0.44%). The soil contained 210, 16.32 and 122 kg ha-1 available N, P2O5 and K2O, respectively. The treatment comprised of nine treatments viz., RD of N and P + 0 kg K (T1), RD of N and P + 30 kg K ha-1 (T2), RD of N and P + 60 kg K ha-1 (T3), RD of N and P + 90 kg K ha-1 (T4), RD of N and P + 120 kg K ha-1 (T5), RD of N and P + 150 kg K ha-1 (T6), T2 + 5 t FYM ha-1 (T7), T3 + 5 t FYM ha-1 (T8) and T4 + 5 t FYM ha-1 (T9). There was no marked effect of different treatments on number of cob plant-1, length of cob, girth of cob and test weight. However, number of grains cob-1 was found significantly higher in treatment T9 (T4 + 5 t FYM ha-1). Grain yield, stover yield and stone yield were significantly influenced by different treatments. The maximum grain yield (63.19 q ha-1), stover yield (101.61 q ha-1) and stone yield (14.61 q ha-1) were recorded under treatment T9 (T4 + 5 t FYM ha-1).
