Study Notes

Horticultural Crop Production Guide

High fruit/vegetable production: India's fruit and vegetable output reached 315 million tonnes in 2018-19, second only to China. This despite challenges like shrinking arable land, drought, low soil organic matter, nutrient deficiencies, and farmers leaving agriculture.
Tamil Nadu Agricultural University (TNAU) role: TNAU develops improved crop varieties, hybrids, and technologies (including nanotechnologies for preservation) for fruits, vegetables, spices, plantation, medicinal crops, and flowers in Tamil Nadu. These are widely adopted by farmers across the country.
"Crop Production Guide (CPG) – Horticulture 2020": This guide provides comprehensive information on crop practices, including varieties, hybrid options, management techniques, protected cultivation, drip fertigation, nematode control, integrated weed management, pest and disease management, labour-saving machinery, and post-harvest procedures.

Mango Fertigation

Manure and Fertilizer Application: Application rates for FYM, Nitrogen (N), Phosphorus (P), and Potassium (K) are provided for different tree ages.
Fertigation Schedule (for all stages): Specific percentages of Nitrogen, Phosphorus, and Potassium are suggested for different developmental stages (after harvest, pre-flowering, flowering to fruit set, fruiting development) using HDP (Drip Irrigation Fertigation).
Drip Fertigation (HDP) Application: Specific NPK dosages per bearing tree per year via drip fertigation are detailed in a schedule based on application stage. Each stage should be divided into multiple doses applied weekly.

Mango Diseases and Pests

Powdery Mildew: Control using wettable sulphur (0.3% spray or dust) or azoxystrobin. Multiple applications are recommended after pruning.
Downy Mildew: Control using Pseudomonas fluorescens and azoxystrobin at specific time intervals after pruning. Infected portions should be removed. FYM and Pf1 should be applied.
Anthracnose: Control using Bordeaux mixture, copper fungicides or fluopicolide/fosetyl aluminium formulations at specified application time intervals.
Combined Infections (Downy, Powdery Mildew, and Anthracnose): Use specific fungicides like carbendazim/mancozeb, iprodione, copper sulphate and mancozeb to control multiple diseases.
Other Diseases/Pests: Additional disease and pest management strategies are mentioned for various specific treatments.

Fruit Quality and Yield

Yields (Different Fruit Types): Estimated yields for Thompson Seedless, Muscat Hamburg, Red Globe, Crimson Seedless, Anab-e-Shahi and Arka hybrids are given in tonnes per hectare (ha) per year.

Fruit Improvement Practices

Quality improvement in Muscat Hamburg: Spray potassium chloride (0.2%) at specific times after berry set.
Quality improvement in seedless grapes: Use of plant growth hormones (GA3, Brassinolide, 6-BAP, CPPU) to enhance yield and quality, and specific application times/concentrations are specified.

Guava specific instructions

Guava varieties: Specific guava varieties are listed.
Soil and climate: Guava can grow in a variety of conditions but prefers well-drained soils with irrigation.
Planting material: Guava can be propagated through layers and grafts.
Planting Season: June-December
Spacing: 5-6 m either way
Plant Protection: Disease specific advice is provided
Pests: Control measures for tea mosquito bug, aphids, mealybugs, and fruit flies are included.
Diseases: Handling advice and specific treatment for red rust control are mentioned.
Root Knot Nematodes: Information on nematode control and prevention strategies via air layers, sterilization, soil media or intercropping with marigold is available.

Crop Harvest and Markets

Harvest Seasons (Ambe, Hasta, Mrig Bahar): Specific harvest months.
Growing and Market districts: Location of growing and major markets for horticultural products in Tamil Nadu are detailed.
