PROJECT PROPOSAL TITLE: EFFECT OF LIMING, NPK FERTILIZATION AND MANURE APPLICATION ON GROWTH AND NODULATION OF SOYABEAN GROWN IN ACID SOIL. NAME: HILLARY M. OMONDI OTIENO REG. NO.: A22/0013/2009 SUPERVISORS: • DR. GEORGE CHEMININGWA Dept. Plant Science and Crop Protection 2. DR. SHAMIE ZINGORE IPNI Regional Director, African
INTRODUCTION • Soyabean: family is Fabaceae, genus Glycine and species G. max. It is one of the most important crops in the world. • Global productivity is 95.2M ha=212.6M tons out of which Africa accounts for only 0.4-1%. Nigeria leads in Africa with 48.9% while Kenya accounts for less than 0.1% of Africa's production(FAO, 2009). • The crop is rich in protein-food especially weaning babies(Annan et al, 2003). and feeds for animals; improves soil fertility through BNF; controls weeds egstriga (Adelodun, 2011); oil and biofuel production; development of agro-based industries.
PRODUCTION CHALLENGES • Competition from imports of other edible oil sources such as palm. • Lack of sub-sector policy within the agriculture sector that specifically deals with edible oil sources soyabean included. • Inconsistent supply of high yielding and promiscuous soybean varieties that can fix enough atmospheric nitrogen without the need for artificial supply of Rhizobium bacteria through inoculation. • Declining soil fertility due to low soil pH that affects nodulation and nutrient availability.
PROBLEM STATEMENT • Continuous cultivation without nutrient replenishment; Poor agronomic practices; and Leaching. • All leading to: Nutrient depletion; Nutrient unavailability; Accumulation of Al3+ and Mn2+ which lower soil pH beyond tolerable levels. • Hence, hinder BNF and general soyabean productivity. The overall effect is low production, use of scarce financial resources to import seed oil, soil infertility and food insecurity.
PROBLEM JUSTIFICATION • Soyabean being a high value and multipurpose crop, a strategy is thus required to raise the soil pH to levels conducive for its production and provide adequate nutrients for enhanced soyabean productivity.
OBJECTIVES • General objective To develop nutrient management options for enhancing growth and nodulation of soyabean in acidic soils. • Specific objectives • To investigate the synergistic effects of lime, NPK and manure application on growth and nodulation soyabean grown in acidic soils. • To determine the effect of lime and manure application on acidic soils. • To assess the effect of low soil pH on soyabean growth and nutrient uptake.
HYPOTHESES Specific hypotheses stated in null form • Lime, NPK and manure application have no synergistic effect on growth and nodulation of soyabean. • Lime and manure application have no effect on acidic soils. • Low soil pH has no effect on growth of and nutrient uptake by soyabean.
MATERIALS AND METHODS • Experimental site: Greenhouse pot experiment at CAVS-UoN field station. • Soil source: Two locations, Eshirale and Masaba from Kakamega county, ButereMumias district. • TREATMENTS T1- Control; T2- NPK at 20kgN/ha, 30kgP/ha and 60kgK/ha from, urea, TSP and MOP respectively; T3- Manure(10t/ha); T4- Lime(5t/ha); T5- NPK + Manure; T6- NPK + Lime; T7- Lime + Manure; T8- Manure + lime + NPK.
MATERIALS AND METHODS CONT…. • Soil sampling: 5 samples at a depth 0-15cm will be collected from each site in a W manner then bulked for the site. Soils will then be air-dried, screened through 0.5cm sieve(Fageria, 2005), mixed with the treatments and then filled into the pots, each 4kg of soil. • Planting: 3 seeds per pot uniformly spread and covered with soil. • Watering: At least twice a day to maintain the soil at field capacity. • Weed control: Mannual by uprooting the seedlings soon as they emerge.
EXPERIMENTAL DESIGN • Pots arrangement: Perpendicular to the path of the sun in the greenhouse. • Layout of the experiment: Randomized complete block design. • One Block
DATA TO BE COLLECTED • The data to be collected are: • Time of emergence. • Leaf surface area at 50-60% flowering. • Plant heights at 50-60% flowering. • Plant tissue analysis for NPK 50-60% flowering • Soil pH at end of the experiment. • Nodulation at 50-60% flowering; • Number of nodules per plant, • Fresh and dry weights of nodules per plant.
DATA ANALYSIS • Data entry: Raw data will be keyed in Microsoft excel computer package. • Data analysis: Data will be subjected to ANOVA at p=0.05 using GenStat computer software 13th Edition (SP2). Means will then be compared using Duncan's multiple-range test at p=0.05. EXPECTED OUTPUTS • Special project report.
