Effect of enhanced doses of nitrogen and phosphorous on grain yield and its attributes in the late sown wheat (Triticum aestivum L.)

A field experiment was conducted at the Research farm of the Department of Agriculture, Maharishi Markandeshwar University, Mullana, Ambala during Rabi season of 2022. The present investigation entitled “Effect of enhanced doses of nitrogen and phosphorous on grain yield and its attributes in the late sown wheat (Triticum aestivum L.)”. The experiment was arranged in a Factorial Randomized Block Design (FRBD) with Three variety (WH-1142, HD-2967, WH-1080) and 4 treatments such as field research were conducted at the Department of Agriculture research farm, Maharishi Markandeshwar (Deemed to be University), Mullana, Ambala while the Rabi season of 2022. with Four treatments. In order to set up the experiment a randomized block design was used: T1-(100% RDF 150N + 60P + 60K) T2- (100% RDF+25% higher nitrogen) T3- (100% RDF+25% higher phosphorus) T4-(Control). In this research the hybrid variety of wheat HD-2967 was taken. The results from the data under this research revealed that by the application of (100% RDF + 25% higher nitrogen) the recorded highest in all parameters like growth attributes, yield and its attributes and economics. Highest grain yield, straw yield and biological yield was (48.26, 57.99, 106.25 q ha-1) respectively. Among all the treatments, the application of (100% RDF+25% higher nitrogen) recorded highest in all plant height at harvest, at 30, 60, 90 and at harvest stage DAS. Yield and its attributes like harvest index, grain yield and straw yield and biological yield was also observed under T2 (100% RDF + 25% higher nitrogen).
