Abstract

Aim: Increasing the input use efficiency by planting of guava on raised bed, mulched with black polythene sheet along with fertilizer application through drip and foliar spray of micro-nutrients (zinc and boron).

Methodology: Experiment was carried out during 2015-2019 for mrig bahar crop in Lalit guava planted at 3 × 3 m spacing in ICAR-CISH, Lucknow with 5 different treatments (T1 = Raised bed +drip irrigation @ 80% PE + fertigation @ 75% RDF + mulching with 100µ black polythene + micro-nutrient spray in July and August @ 0.2% each of zinc sulphate and boric acid, T2 = Raised bed + drip irrigation + fertigation + mulching, T3 = Raised bed + drip irrigation + fertigation + micronutrient sprays, T4 = Raised bed + drip irrigation +micro-nutrient sprays + soil application of RDF @ 50:25:50 g N:P:K, T5 / control = Flat bed + soil application of RDF + basin irrigation).

Results: Canopy volume, trunk-cross sectional area and yield were significantly increased in T1, which could be attributed to better microclimate in root zone, resulting in improved growth and yield.      

Interpretation: The findings of this research have generated the technique of improving space, water and nutrient use efficiency under high density planting system of guava cv. Lalit in subtropical climate which will help the guava growers for sustaining quality production.

Key words: Fertigation, High density planting, Mulching, Raised bed, Yield efficiency
