Fertigation Schedule for Pomegranate: Month by Month

Fertigation is the practice of delivering fertilisers dissolved in irrigation water directly through a drip system to the root zone of the plant. Research published in multiple Indian journals confirms that fertigation reduces both irrigation and nutrient requirement by 30 to 50 percent compared to conventional surface application within plant basins. For pomegranate farmers with drip systems already installed, fertigation is one of the highest return improvements you can make to your farming program.

Why Fertigation Works Better Than Broadcasting

Research conducted on pomegranate variety Bhagwa in Gangapur, Latur, Maharashtra found that drip fertigation at 100 percent recommended dose on alternate days significantly increased vegetative growth, yield-contributing characteristics, and leaf nutrient status compared to conventional irrigation with surface-applied fertiliser. The reason is simple. Pomegranate feeding roots are concentrated in the top 50 to 60 centimetres of soil directly under the drip zone. Fertigation delivers nutrients precisely to this zone where roots can absorb them immediately. Broadcasting fertiliser on the soil surface wastes nutrients to volatilisation, surface runoff, and leaching below the root zone. An experiment on Super Bhagwa pomegranate published in 2023 to 2024 found that integrated nutrient management combining 75 percent recommended dose of fertilisers with poultry manure, bio NPK consortium, seaweed extract, humic acid, and micronutrient foliar spray gave maximum fruit yield of 13.30 kg per tree and 22.18 tonnes per hectare with TSS of 15.02 degrees Brix.

Recommended Annual Nutrient Dose for Bearing Trees

The National Horticulture Board and ICAR-NRC Pomegranate Solapur recommend a total annual dose for mature bearing pomegranate trees of 600 to 700 grams of nitrogen, 200 to 250 grams of phosphorus, and 200 to 250 grams of potassium per tree per year. Apply the full dose of phosphorus during the first irrigation after bahar pruning as phosphorus moves slowly in soil and needs to be placed early. Split nitrogen and potassium into three to four equal doses throughout the growing season. Add micronutrients including zinc, iron, manganese, and boron based on leaf and soil analysis done every season.

Month by Month Fertigation Guide for Mrig Bahar

The following schedule is based on Mrig Bahar which is the most common bahar in India with irrigation withheld from March to May, pruning in May, and new growth starting in June after irrigation is resumed. During the rest period from March to May, withhold all irrigation and fertigation. This is the stress phase. In May at pruning, apply full phosphorus dose as soil application along with organic manure. In June when irrigation resumes after pruning, apply the first dose of nitrogen as 20 percent of the annual dose to support new vegetative growth. Apply potassium at 20 percent of annual dose. Use water soluble fertilisers through the drip for best uptake. In July and August during active vegetative growth and flower bud development, apply nitrogen at 25 percent of annual dose and potassium at 25 percent of annual dose split into two fortnightly applications. Continue micronutrient foliar sprays of zinc sulphate at 0.5 percent and borax at 0.2 percent during this phase. In September and October during fruit set and early fruit development, shift the fertiliser emphasis toward potassium. Apply nitrogen at 20 percent of remaining annual dose and potassium at 30 percent of annual dose. High potassium at this stage improves fruit size and reduces cracking. In November and December as fruits approach maturity in the last 60 days before harvest, reduce nitrogen completely and apply the remaining potassium. High nitrogen near harvest promotes vegetative growth at the expense of fruit quality and colour. Continue calcium foliar sprays at 0.5 percent calcium nitrate fortnightly to strengthen peel and reduce cracking.

Micronutrients That Cannot Be Ignored

Micronutrient deficiency is very common in pomegranate orchards across India and directly reduces yield and quality even when major NPK fertilisers are applied correctly. Zinc deficiency shows as small leaves and poor fruit set. Apply zinc sulphate as foliar spray at 0.5 percent three times during the growing season. Boron deficiency causes corky skin and poor pollination. Apply borax at 0.2 percent as foliar spray at flowering and fruit set. Iron deficiency shows as yellowing between veins on new leaves, common in alkaline soils. Apply chelated iron through drip or as foliar spray. Research from 2026 published in Biochem Journal confirms that integrated nutrient management combining chemical fertilisers with biological inputs and biostimulants significantly improves pomegranate quality attributes compared to chemical fertilisers alone.

Organic Inputs Alongside Fertigation

Do not rely exclusively on chemical fertilisers even with an excellent fertigation system. Apply 10 to 15 kg of well-rotted farmyard manure or compost per tree every year as a basal application after pruning. Research confirms that combining organic manure with chemical fertigation at 75 percent of the recommended dose gives comparable or better results than 100 percent chemical fertilisation alone, while improving soil health for the long term. Vermicompost at 5 kg per tree is another excellent option. Apply neem cake at 1 to 2 kg per tree annually which provides slow-release nutrients while also suppressing soil-borne pests and diseases.
