Abstract:
The present investigation entitled “Response of foliar application of micronutrients and plant growth regulator on yield and economic feasibility of guava (Psidium guajava L.)” was conducted on six-year-old guava plants grown in sodic soil condition at Main Experimental Station, Department of Fruit Science, Acharya Narendra Deva University of Agriculture & Technology Kumarganj Ayodhya (U.P) during the year 2019-20 to investigate the response of foliar application of micronutrients and plant growth regulators on yield and economic feasibility of guava. The experiment comprised of two foliar applications after flowering during August and at the pea stage during October of zinc sulfate 1.0% (N1) Borax 1% (N2), NAA 50ppm (N3), and Control (N0) on the two cultivars Shweta (V1) and Lalit (V2) with three replication. The data was recorded and analysed by using Factor Randomised block design (F.R.B.D). Under the investigation, guava fruits were studied for the parameter of number of flowers per plant, fruit set, fruit retention, number of fruits per plant, fruit yield per plant, fruit yield per hectare, gross income, net income, cost of cultivation and cost benefit ratio. During the investigation, the result revealed that the fruiting attributes as well as yield of guava was recorded significantly superior with treatment of N2V2 as compared to other treatments. However, the treatment N3V2 was recorded most beneficial in terms of economic return. Hence, concluded that application of FYM+NPK (400g: 300g: 250g) + Borax (1%) in cv. Lalit increase the fruiting and yield of guava while for the maximum economic return application of FYM+NPK (400g: 300g: 250g) + NAA 50 ppm in cv. Lalit and recommended to guava producers in the Eastern Uttar Pradesh..
