Abstract/ Executive Summary:

An experiment was conducted at the Field Laboratory of the Department of Agroforestry, Bangladesh Agricultural University, Mymensingh during the period from November 2013 to February 2014 to observe the performance of winter crop viz. mustard in alley cropping system developed with Ipil-ipil (Leucaena leucocephala) following Randomized Complete Block Design (RCBD) with three replications. Different treatments of the experiment were T₀ = without fertilizer and manure, T₁ = Ipil-ipil leaf biomass (ILB) as manure, T₂ = ILB + ½ RFD (Recommended Fertilizer Dose), T₃ = ILB + ¼ RFD (Recommended Fertilizer Dose) and T₄ (open field and without manure and fertilizer). Growth and yield of this crop was recorded in this alley cropping system. It was found that growth parameters viz. plant height (cm), number of leaves per plant, leaf length (cm), length of floral rachis (cm), no. of branches/plant, length of branches (cm), no. of siliqua/plant, length of siliqua (cm), no. of seed/siliqua, no. of seed/plant, weight of 1000 seeds (g) of mustard were almost similar in all manure/fertilizer treated plots. Performance of this winter crop in terms of growth and yield parameters remarkably lower in without manure/fertilizer treated plots inside and outside (control) of the alley cropping system. Yield of mustard was statistically similar with all fertilizer treated plots but it was drastically reduced in without fertilizer treated plots. The highest yield was 2.41 t/ha in ILB and ½ RFD treated plot and lowest was 1.70 t/ha respectively in without fertilizer and manure treated plot. Yield of mustard was 5-7 % and 10-12 % lower in ILB + ¼ RFD treated condition and only ILB treated condition, respectively compare to treatment T₂ (ILB and ½ RFD). It was found that growth and yield of this crops remarkably lower (40-50%) in control situation both inside and outside the alley cropping system but in both control situation growth and yield of this crop was statistically similar. Therefore, it is concluded that mustard can be successfully cultivated under alley cropping system using ipil-ipil green leaf biomass as manure excluding the use of synthetic fertilizers without significant yield loss.

Start Date: 00-11-2013

End Date: 00-02-2014

Program Area: Farming System

Commodity: Ipil-ipil, Mustard

Objectives:

1. To investigate the performance of mustard under alley cropping system.

Methodology:

The experiment was carried out at the experimental farm, Department of Agroforestry, Bangladesh Agricultural University, Mymensingh, during the period from 10th November 2013 to 27th February 2014. The place is geographically located at about 24°75" North latitude and 90°50' East longitudes In this study, two years old Ipil-ipil (Leucaena leucocephala) were used as tree component and mustard used as crop component. The study was done in previously established two years old Leucaena leucocephala hedges. Hedges were in North-South direction and distance between the two rows of hedges was 10 ft. The hedge materials were cut at 2.5 ft. height one month before the crop cultivation and mixed thoroughly into the alley. Winter crops viz. Mustard with five treatments were laid out following the Randomized Complete Block Design (RCBD) with three replications. Five treatments for this study were T₀ =Without fertilizer and manure, T₁= Ipil-ipil leaf biomass (ILB) as manure, T₂ = ILB + 1/2 RFD (Recommended Fertilizer Dose) and T₃ = ILB + 1/4RFD (Recommended Fertilizer Dose), T₄ = Control (open field i.e. outside of alley cropping and without fertilizer and manure). Among these five treatments, 4 (four) were executed under alley cropping system and rest one i.e. T₄ is executed in open field condition. Layout of the experiment inside alley cropping system where total 12 (twelve) plots (4 × 3) were made for 1st four treatments (T₀, T₁, T₂ and T₃), for each test crop. Individual plot size was 7ft x 9ft i.e. 5.85 m². Sixty plants of mustard were selected from each plot for data collection. Different growth and yield contributing parameters were recorded in different time periods viz. vegetative, begining of folowering, end of flowering and harvesting period. The parameters were studied such as plant height (cm), no. of leaves per plant, leaf length (cm), length of floral rachis (cm), no. of branches/plant, length of branches (cm), no. of siliqua per plant, no. of seed per siliqua, no. of seeds per plant, weight of 1000 seeds. Fresh yield was determined from summation of total seeds weight from a plant and then converted it to t/ha. The data were collected from the experiment at different stages of various growths and then analyzed statistically by using PC MA-STAT, MSTAT-C Package programmed and wasp2 software package to find out the statistical significance of the experimental results. The mean differences were evaluated by Duncan’s New Multiple Range Test (DMRT) and also by Least Significant Difference (LSD) test.
