tomato fertilizer management

Application of farmyard manure to an extent of 8-10 tonne/acre is desirable for final ploughing.

State	Fertilizer recommendation (NPK in kg/acre) for local varieties	Fertilizer recommendation (NPK in kg/acre) for hybrid varieties	Time of Application
Andhra Pradesh and Telangana	40:24:24	60:36:36	Whole P & K as basal. N should be applied in 3 equal splits on 30, 45 & 60 days after transplanting (DAT).
Karnataka	Irrigated: 46:40:24 Rainfed: 24:20:12	100:100:100	Whole P, K & 50% of N should be applied in the furrows as basal dose. Rest 50% of N should be applied after 4 weeks of transplanting.
Maharashtra	80:40:40	120:60:60	Whole P, K & 50% of N should be applied as basal dose. Rest 50% of N should be applied in three equal splits at 20 days interval.
Uttar Pradesh, Madhya Pradesh, Bihar	40-60:24-32:20-24; 80N for indeterminate varieties	80:24-32:20-24	Whole P, K & 1/3^rd of N should be applied as basal dose. Rest N should be divided into two equal parts and applied at 25-30 and 45-50 DAT.
Gujarat	60:40:20	80:100:100	Varieties – whole P, K & 50%N as basal dose and rest N at 30 DAT. Hybrids – whole P, 40 kg of K & 20 kg of N as a basal dose and rest 60 kg of N & 60 kg of K in three equal splits at 30,45 & 60 DAT.

Micronutrient mixtures can also be sprayed to boost the crop growth and to manage the deficiencies.
Fertilizer requirements may vary from region to region. So, it is advisable to apply the fertilizers based on the soil test recommendations.

Micronutrient sprays should be done @ 3-5g/litre for 2-3 times once in every 10-15 days after 45 days of transplanting and number of sprays can be increased based on the crop duration.
Foliar nutrition with 19:19:19, potassium sulphate @ 5g/L, during the fruit development stage for every 10-15 days interval will help in developing fruit size and quality.
Calcium nitrate @5 g/L should be sprayed instead of calcium nitrate at 10-15 day intervals from 60 days after planting until fruit harvesting.
Ensure not mixing of calcium with 19:19:19 or any phosphorus containing nutrients to avoid incompatibility.
