Abstract:
The experiment entitled “Studies on the response of different guava (Psidium guajava L.) varieties to different mulches and pruning times for quality parameters under Ultra High Density Planting System” was conducted during the year of 2019 and 2020 at Research Farm of Precision Farming Development Centre (PFDC), College of Agriculture, IGKV, Raipur (C.G.). The experiment was conducted under factorial randomized block design (FRBD) with three factors and their different levels, mulching materials i.e. M1- Control (Non mulch), M2- Poly mulch and M3- Paddy straw, three varieties i.e. V1- Allahabad Safeda, V2- Lalit and V3- Lucknow-49 and two pruning months i.e. P1- February, P2- June. The treatment comprising of 18 treatment combinations viz., M1V1P1, M1V1P2, M1V2P1, M1V2P2, M1V3P1, M1V3P2, M2V1P1, M2V1P2, M2V2P1, M2V2P2, M2V3P1, M2V3P2, M3V1P1, M3V1P2, M3V2P1, M3V2P2, M3V3P1 and M3V3P2.
The quality parameters of guava in terms of total soluble solids, TSS: acid ratio, ascorbic acid, total sugar and non-reducing sugar was proved to be highest with the treatment M2- Poly mulch, V2- Lalit and June pruning while, reducing sugar was recorded maximum under paddy straw and V3- Lucknow-49 during both the year 2019 and 2020. The acidity of guava fruits recorded lowest by the application of same treatment.
