Effect of Sheep Manure and Phosphorus Fertiliser on Productivity of Snap Bean (Phaseolus vulgaris L.) in Northern Rwanda

Abstract

Aims: Snap bean (Phaseolus vulgaris L.) productivity is low in Rwanda. Investigations were carried out to assess the productivity of Snap bean using pot experiments. Methodology: The experiment was laid out in a completely randomized design with seven (7) treatments: Compost (T0), Cow manure (T1), Sheep manure (T2), Compost with diammonium phosphate (DAP), DAP alone (T3), Cow manure with DAP (T4), Sheep manure with DAP (T5) and control (T6) on Andisol and Oxisol replicated three (3) times. Results: The results showed that the pod yield was the highest in Andisol (2.39 tha-1) and the application of sheep manure significantly (P<.001) increased the leaf area, the number of leaves (P = .01) and the plant height (P= .

Effect of Compost Rates and Spraying with some Biostimulant Substances on Growth, Yield and Quality of Snap Bean

“…Ascribed this increase in vegetative growth characteristics of snap bean allied with increasing compost rates to mineralization of organic nitrogen contained in compost that gradually released nitrogen during the growing season, the role of compost in reducing the soil pH especially in the rhizosphare, thereby, increases the availability of most essential macro and micro nutrients, positive role of nitrogen secreted from compost on division and elongation of stem meristematic tissues and plant photosynthesis assimilates, and consequently enhance establishment and growth of snap bean. These results are in good compatible with those recorded by Abou El-Hassan et al (2017), Bucagu et al (2017) and Changa et al (2017).…”

“…These results ascribed to the role of compost in improving vegetative growth, besides compost is a source of slow release nutrients, and contains a number of macro and micronutrients, and consequently high accumulation of dry matter which resulted increase pod yield per unit area and increase all yield components. These results are harmony with those of Abou El-Hassan et al (2017) and Bucagu et al (2017).…”

“…On the other hand, Abou El-Hassan et al (2017) showed that all treatments of compost and vermicompost without mineral fertilizers decreased all vegetative characters, early and total yield of green beans plants and nitrate content of green bean pods. Bucagu et al (2017) found that application of organic fertilizers significantly increased leaf area, plant height, number of leaves, pods, weight of pods and total pod yield of snap bean. Changa et al (2017) indicated that compost addition up to 20% had a positive influence on plant emergence and plant growth index (shoot height, stem diameter, leaf area, root dry weight and plant biomass) of green bean.…”

Pyrethrum marc rates and intra-row spacing influence on selected soil chemical parameters and yield of bush bean (Phaseolus Vulgaris L.) grown on andosol under rainfed conditions

“…The bush bean yield had a weak, positive, and significant correlation with all selected parameters except pH. Even though the relationship between yield and other chemical attributes was weak, the yield increased with the increase of nutrients up to the application of 10 t ha-1 of organic fertilizer (Bucagu et al, 2017;Kibunja et al, 2012). The positive correlation between parameters indicated their inter-dependency (Duan et al, 2019;Nwokwu, 2020).…”

Effect of Organic, Mineral and Bio-Nitrogen Fertilization on Growth and Productivity of Some Snap Bean Cultivars Grown in Clay Soil

“…In this regard, fertilizing snap bean with organic, mineral and bio nitrogen increased plant growth (Arisha and Bardisi, 1999;Mahmoud et al, 2010;El-Awadi et al, 2011), leaf pigments (Arisha and Bardisi, 1999 on snap bean, Shokr, 2000 ; El-Mansi et al, 2000 on pea), yield and pod quality (Shehata et al, 2011;El-Seifi et al, 2013;Feleafel and Mirdad, 2014;Mandour, 2014;Sathe et al, 2015;Alhrout et al 2016;Bucagu et al, 2017;Shafeek et al, 2017 on snap bean).…”
