Crop combinations

There are three types of Agroforestry systems namely, Agrisilvicultural, Agrihorticultural and Agrihortisilvicultural.

Among the above three systems Agrihortisilvicultural is highly diverse in vegetation, with many tree and agricultural crops mixed together resulting in highest productivity of total aboveground biomass per hectare per year.

Models Crop Combinations
1 Agri-Silviculture - Casuarina + Maize / Fodder Sorghum / Pulses
Casuarina + Vegetables (Chillies / Tomatoes / Pumpkin / Groundnut)

2 Horti + Silvi - Casuarina + Mango
Casuarina + Coconut
Casuarina + Banana
Casuarina + Teak + Papaya
Casuarina + Drumstick + Hybrid Tomato
Casuarina + Tamarind + Drumstick
Casuarina + Teak + Eucalyptus + Guava

3 Silvipasture - Casuarina + Napier grasses

4 Bund Planting - Casuarina as Wind Breaks

5 Block Planting - Block planting of Casuarina

6 Line / Boundary Planting Boundary planting in single as well as double rows.
Casuarina + Teak on Boundary
Casuarina + Coconut as line planting

7 Homestead Multi-storeyed Cropping System - Teak / Casuarina / Banana / Vegetables.

Dear Vishnu

Need your expertise help from you for tree plantation.
After regular search in the Internet (with the help of your posts also),I found some of the Fast growing trees below,need advise from you on selecting those trees.
We are having five acres of land on that we are shifting from paddy and sugarcane to tree plantation.would also like to know that shall we plant these plants in the same land(different rows)?. what is the spacing required if we are mixing these plants in the same field.

Kumil(Gmelina Arborea)
Malia Vembu(Melia Dubia)
Kaya Senegalensis (kaya Senegal mahogany)
Anthrocephalus cadamba (vellai kadhambu)-looks good
Casuarina Junghuniana ( Junguniana Savukku)
Bamboo -Tissue culture
(malocanna bacciefera,Bambusa nutans,B Bamboos,B tulda, B.vulgaris,B Balcooa)
Grewia tiliaefolia(Thadasu,Sadhaci)
AlbiZia falcataria (kattumaram)
Tectona Grandis (Teak).

Thanks in advance

Dear Sir,

Thank you for visiting my blog. I request you to go thro' the following links before going all out to plant trees:

My today's post on: Anthocephalus cadamba.
Timber tree selection - A check list.

There is no fixed rule or records to suggest correct crop combinations (i.e). planting 3 or more tree species in the same plot.

You can maintain a spacing of 10' x 10' for Melia dubia, Kumil and Kaya in alternate rows and in the middle of every row you can plant C.junghuhniana every 5' in single direction. See this link.
(http://agrowmania.blogspot.in/2010/04/melia-dubia-tamil-malai-vembu.html)

There will be competition for available resources if you mix Bamboo, Grewia and Albizia in the above plan. Teak can be planted separately and regarding Kadamba more details about your field location, soil type, soil depth, humidity, irrigation potential Etc., are required.

Thanking you,

Yours friendly,

Thank you..Thank you for your suggestions.

The Land is located in Tamil Nadu near.....

Would also like to know where I could get the Tree saplings for the below in Tamil Nadu.

Melia dubia.
Kumil
Kaya
Anthocephalus cadamba
C.junghuhniana (tissue culture available ?)
Teak ( tissue culture available)

Please suggest

Dear Vishnu,
Thank you for your swift response, this really motivates me.
Just to summarize I finalized my plan to go for Multi-storey Cropping System as suggested by yourself

1) Melia dubia by spacing 10’X10’
2) C.junghuhniana spacing 5’X15’ which is in-between Meli dubia & Kumil
3) Kumil by spacing 10’X10’
4) Boundary Planting Boundary planting in single as well as double rows (C.junghuhniana & T.C Teak)

Please help to understand the boundary plantation who to do that in single as well as double rows please explain what is the spacing required for single & double ?

Thanks in advance

Dear Sir,

I am happy that you have got it correct.

Correction: Spacing between one row of C.J with another row of C.J will be only 10' and not 15' as you presume. Spacing between plant to plant in East - West direction will be 5' and row to row in North-South direction will be 10' only.

Suggestion 1 : If you select C.J as border crop and wants to retain it for a long period of time, then it is correct. But if you have plans to harvest it in 3 to 4 years then there will be wide gap in the field boundary. Going for two rows of CJ in zigzag fashion with 5' x 5' spacing or a single row with 4' spacing is good. Please note that tree plantations normally won't require double row of plants as wind breakers.

Suggestion 2 :The other option is planting Gliricidia as fence in a single row with 3' spacing. It is a good wind barrier, very high leaf mulch provider (4 harvests/Year) and a 'N' fixing tree. The only negative aspect is that you will not be able use harvested branches of Gliricidia for any other purpose other than for mulching.

Thanking you,

Yours friendly,
A.Vishnu Sankar
