Abstract:
During the Rabi season of 2022, an experiment named "Effect of doses of phosphorus and zinc on growth and yield of late sown wheat (Triticum aestivum L.)" was carried out at the agricultural research facility of Rama University in Kanpur. The experiment used a Factorial Randomized block design with 12 treatments and 3 replications. The 12 treatment combinations include 3 levels of zinc (0 kg, 5 kg, and 10 kg), and 4 levels of phosphorus (40 kg, 60 kg, 80 kg, and 100 kg). The following growth parameters were observed: plant height, number of shoots (m-2), dry matter accumulation at 30, 60, 90, and at harvest; leaf area index at 30, 60, and 90 DAS; yield attributes, including number of spikelets per spike, spike length, number of grains per spike, and test weight (g); and productivity characters, including grain yield (q/ha), straw yield (q/ha), and harvest index (%). According to the research, the levels of phosphorus and zinc at 100 kg per hectare and 10 kg per hectare, respectively, were superior to all other levels. The farmer may be advised to use 100 kg of phosphorus and 10 kg of zinc per hectare to promote the healthy development, productivity, and quality of wheat plants. The cost of cultivation was low, and the net return was high for the phosphorus and zinc combination.
