Abstract:
The present investigation entitled “Response of foliar application of micronutrients and plant growth regulator on physio-chemical attributes of guava (Psidium guajava l.)” was conducted on guava plants grown of about 6 six year old in the 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 study the response of foliar application of micronutrients and plant growth regulators on physio-chemical attributes of guava. The experiment contains of two foliar applications after flowering in August and at the pea stage in October of zinc sulfate 1.0% (N1) Borax 1% (N2), NAA 50ppm (N3), and Control (N0) on the two cultivar 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 fruit weight, fruit size (length and width), fruit volume Total soluble solids, Reducing sugars, Non-reducing sugar, and Total sugars, Acidity, and Ascorbic acid. During the investigation, the result concluded that maximum weighted fruit in treatment N2V1, while, highest volume fruits were observed in treatment N1V1 and size of fruit in the treatment N3 V1. The total soluble solids, Reducing sugars, non-reducing sugar were significantly highest in treatments N3V2, N2 V2, N1 V2 respectively. The maximum acidity was recorded in the treatment N2V2 and ascorbic in treatment N3 V1; therefore, concluded that application of FYM+NPK (400g: 300g: 250g) + Borax (1%) in cv. Lalit improved physiochemical attributes of the fruit.
