Abstract/ Executive Summary:

A field experiment was conducted in an established tree orchard of Sissoo (Dalbergia sissoo) and Mahogoni (Swietania macrophylla) at the Agroforestry field of the Regional Agricultural Research Station of BARI, Jamalpur during November 2005 to April 2006 to evaluate the performance of growth and yield of wheat with various fertilizers and manure application. Wheat (Triticum aestivum) var.Kanchan was grown under the different treatments combinations of this Agrisilvicultural system. The data were collected seven times, first to six times TDM at 15 DAS intervals and finally after harvesting. The results showed that application of organic manures and chemical fertilizer under two species of trees influenced independently and also in combination. The highest 1000-grain weight (42.73 g) was found under Sissoo with poultry manure treatment combinations. Also the highest harvest index (40.00) was obtained under Sissoo with poultry manure and chemical fertilizer treatment combination. The highest yield (1.35 t ha^-1) was obtained from open area with poultry manure + chemical fertilizer followed by Sissoo (1.15 t ha^-1) with poultry manure treatment combinations. Therefore, all parameters produced the highest performance in open area compared to tree-wheat association in respect of wheat cultivation. This study indicated that Dalbergia sissoo was the species where wheat grown with minimum yield reduction as compares to open area.

Keywords: Manure and Fertilizers, Wheat

Location: Regional Agril. Res. Station, BARI, Jamalpur

Start Date: 00-11-2005

End Date: 00-03-2006

Program Area: Crop-Soil-Water Management

Commodity: Wheat

Objectives:

1. To evaluate the open spaces of tree orchard for wheat cultivation and to find out a suitable combination of chemical or organic manures for successful wheat production under these agrisilvicultural systems.

Methodology:

The site of the experiment is located at about 24056/ North latitude and 89055/ East longitude and the plots were at the southern part of the Regional Agril. Res. Station, BARI, Jamalpur, which is under the municipal area of Jamalpur town. Duration of the experiential period was from November 2005 to March 2006 with three replications. Soil of the experimental plot was low in organic matter (1.2?), evolved from the Old Brahmaputra floodplain alluvium and it belongs to the Sonatala soil series. Wheat (Triticum aestivum L.) var. Kanchan was used as the test crop. The experiment was laid out following a Randomized Complete Block Design with two factorial arrangements. Factor: A = Tree species i) Open Area (Control): OA ii) Dalbergia sissoo: DS iii) Swietania macrophylla: SM Factor: B= Fertilization procedure i) Poultry litter @ 10 t ha^-1: P ii) Chemical fertilizer @ 120-16-35-20-2-1 kg N-P-K-S-Zn-B ha^-1: C iii) 50% poultry litter + chemical fertilizer (50%): P+C Total number of experimental plot was 27. Eighteen plots were laid under tree species and the size of each unit plot was 5.5m x 3.5m = 19.25m². Data on growth parameters and dry matter production plant^-1 was recorded at every 15 days. Yield data were collected from 2/3rd portion (wheat plants) of each plot as 1/3rd portion was used to collected data on growth parameters. Data on yield contributing parameters such as Dry matter weight plant^-1 dates (15 days interval), Plant height at harvest (cm), Length of spike (cm), No of spikelets spike^-1, No of grain spike^-1, Weight of 1000 seed (g), Weight grain yield (t ha^-1), Weight of straw (t ha^-1) were recorded and statistically analyzed using the “Analysis of variance” (ANOVA) technique with the help of computer package program (MSTAT). The mean differences were done following new Duncan’s Multiple Range Test.
