Optimum Pruning Strategies for Reducing Crop Suppression in a gmelina-maize Smallholder Agroforestry System in Claveria, Philippines
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'On-farm trials were conducted to assess the effects of four branch pruning levels on maize grain yield, tree growth and stem shape. The experimental plots consisted of gmelina (Gmelina arborea R.Br.) trees planted at 1 x 10 m with maize intercropped in the 10 m-wide alleys between lines of trees. Pruning levels consisted of retaining a live crown ratio of 60-Â70% (T1), 40-50% (T2); 30-40% (T3) and of 20-30% (T4). At the end of the experiment, the total maize grain yield was highest under the high pruning intensity (T4) (18.06 t ha-1) and lowest under T1 (14.48 t ha-1). Maize grain yield under the pruning regime T2 and T3 were 16.08 and 17.21 t ha-1 respectively. Mean annual increment (MAI) in tree diameter was greater (5.0 cm yr-1) under T1 than those at T4 (4.1 cm yr-1). Pruning regimes T2 and T3 resulted in a MAI of 4.7 cm yr-1 and 4.' .
