Response of maize crop to various levels of micro-nutrient application under rain-fed conditions of Azad Kashmir

Abstract

The experiment was conducted to study the response of maize crop to various levels of micro-nutrient application under rain-fed conditions at three different locations of Azad Kashmir in 2016. The experiment layout was in randomized complete block design (RCBD) with 5 treatments and 4 replications. Treatments were different levels of micro-nutrients with basal dose of NPK. Analysis of results showed that application of micro-nutrient (Zn, B & Cu @ of 2:1:2 kg/ha) along with macro-nutrients in maize crop gave significantly high yields in District Muzaffarabad and Kotli. Value cost ratio showed that farmers can get 2 to 4 time more profit by the use of Zn, B & Cu in maize crop. Relationship of nutrients in plant and soil gave positive co-relation (P=0.05), that means greater the nutrients in the soil more nutrient will be absorb by the plants.
