Studies on the response of different guava (Psidium guajava L.) varieties to different mulches and pruning times for yield and yield parameters under ultra high density planting system

Abstract

The present experiment was carried out during 2019 and 2020 to study the response of different guava (Psidium guajava L.) varieties to different mulches and pruning times for yield and yield parameters under Ultra High Density Planting System 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 & V3- Lucknow-49 and two pruning months i.e. P1- February, P2- June. The yield parameters of guava in terms of number of flowers per plant, number of fruits per plants, fruit weight per fruit, fruit yield per plant and fruit yield per hectare was proved to be highest with the interaction effect of M2- Poly mulch, V2- Lalit and P2- June pruning during both the year 2019 and 2020.
