Actually I'm working on Optimization of fertilizer regimes and understorey productivity in four-yr-old Swietenia macrophylla King. standsOptimization of fertilizer regimes and understorey productivity in four-yr-old Swietenia macrophylla King. stands. I applied the dosage of Four fertilizer levels (F1—0:0:0; F2—50:25:25; F3—100:50:50 and F4—150:75:75 kg ha-1 year-1 N, P2O5 and K2O; equivalent to 0:0:0, 50:10.75:20.75,100:21.5:41.5 and 150:32.25:62.25 kg ha-1 per year elemental N, P and K respectively) with Three replication. I would like to know that how we estimate the standard dosage of Mahogany ?
Same plantation area, I also want to know that how estimate the NET yield production of Intercrooping. Here each main plot (Fertilizer levels) (size 40X40 m) again divied into four sub plots will be separated by a buffer strip consisting of at least one row of plants. The sub plot size for the intercrops will be 10x10m. The three herbaceous medicinal crops viz. turmeric (Curcuma longa L.), ginger (Zingiber officinale Roscoe) and wild turmeric (Curcuma aromatica) will be planted in between the central rows of trees in raised beds of size 8x1m.
Dear Vikas
I think the fertilization regimen is very dependent from soil properties, nevertheless, you could check the paper from Santos-Martín 2009. Trade-offs analysis for possible timber-based agroforestry scenarios using native trees in the Philippines

I think it works better to use nitrogen fixing trees like Leucaenas, this also reduces de attack by Hypsipyla grandella, I have not published this. In a nursery study mahogany did not benefit from fertilization. I f you are interested I can find the article by Jhon Mexal.Other source is Forest Ecology and Management 168 (2002) 125–133
