Abstract:
The present experiment entitled “Impact of phosphorus and zinc application on growth and yield of wheat (Triticum aestivum L.) Under middle zone of U.P.” was carried out at Shradheya Bhagwati Singh Agriculture Research Farm, Hajipur, Chandra Bhanu Gupta Krishi Snatkottar Mahavidyalaya, BKT, Lucknow (UP). The experiment was comprising with four levels of phosphorous i.e., (0, 60, 80 and 100 Kg/ha) and three levels of zinc (0,5 and 10 kg ha^-1) thus, all possible 12 treatment combinations were tested in randomized block design (Factorial experiment). Examination of data clearly indicated that increasing levels of phosphorus and zinc were responsible for increased growth and yield attributes. Application of 100 kg P₂O₅ ha^-1 being at par with 80 kg P₂O₅ ha^-1 P₂O₅ ha^-1 produced more taller plants and number of tillers plant^-1as well as maximum LAI at 90DAS. Maximum dry matter accumulation was also noted under 100 kg P₂O₅ ha^-1_. Higher values of test weight, grain yield, straw yield and biological yield was associated with application of 100 kg P₂O₅ ha^-1_. Like phosphorus the highest level of zinc attained maximum values of above growth and yield parameters.
