Effects of NPS and Bio-organic Fertilizers on Yield and Yield Components of Faba bean (<em>Vicia faba</em> L<em>.) </em>in Gozamin District, East Gojjam, Ethiopia

Abstract

Faba bean (Vicia faba L) is the first grain legume in terms of hectarage, total production and foreign exchange earnings in Ethiopia. The current study was designed to evaluate effect of NPS and bio-organic fertilizers on the yield and yield components of faba bean in Debre Markos University research farm. A total of 16 treatments were made from the factorial combination of four levels NPS (0, 50, 100 and 150 kg ha-1) and four levels bio-organic fertilizer (Nil BOF (Bio(Nil)), rhizobium (Bio(IR)), 10 t ha-1 FYM (Bio(FYM)) and FYM+Rhizobium (Bio(FYM+IR))) in randomized complete block design (RCBD) with three replications. The Walki (EH 96049-2) variety, which is high yielding, moderate disease resistant and water-logging tolerant used as test crop. The result experiment showed that, plot treated with Bio(FYM+IR)+NPS100 treatment gave statically maximum effective number of tillers (2.73), maximum number of pods per plant (20.30), hundred seeds weight (76.11g), grain yield (5.62 t ha-1), biomass yield (10.94 t ha-1) and Harvest index (59.91%) than over other treatments received NPS fertilizer with and without bio-organic fertilizers. Therefore, the combined use of 100kg ha-1 NPS with 10 tha-1 FYM and rhizobium inoculation is superior for optimum production of faba bean in study area.

Comparative Effect of Inoculation of Phosphorus-Solubilizing Bacteria and Phosphorus as Sustainable Fertilizer on Yield and Quality of Mung Bean (Vigna radiata L.)

“…Thus, it has resulted that direct use of P is more valuable for the increase in the number of pod and grains than PSB (see Figure 4 ). Ebbisa and Amdemariam [ 30 ] reported that faba bean plants showed the highest number of pods of about 19.43 per plant by applying biofertilizer of farmyard manure with inoculation of Rhizobium at a 150% rate of NPS, while the lowest number of pods of about 11.57 per plant was recorded by applying biofertilizer of farmyard manure without Rhizobium inoculation at 0% rate of NPS. Zafar et al [ 29 ] experimented on chickpea and revealed that the use of PSB along with synthetic fertilizer showed the highest number of pods and number of grains of 36.66 and 1.58 per plant, respectively, while the maximum number of grains were noted as 4 per pod.…”

“…The maximum harvest index of about 13.28% (V4) was observed with P and 11.71% (V2) with PSB. Ebbisa and Amdemariam [ 30 ] reported that faba bean plants showed the highest harvest index of 59.91% by applying biofertilizer of farmyard manure with inoculation of Rhizobium at 100% rate of NPS, while the lowest harvest index of 39.37% was recorded by applying biofertilizer of farmyard manure with Rhizobium inoculation at 0% a rate of NPS. Chattha et al [ 27 ] revealed that a maximum harvest index of 0.213% was achieved in mung bean plants by treating with Rhizobium and PSB.…”

Effects of Lime, Manure and Kitchen Ash Application on Yield and Yield Components of Faba Bean (&lt;i&gt;Vicia faba&lt;/i&gt; L.) on Acidic Soils of Gozamin District

“…The return of most treatments increased as crop yield raised due to minimum increment in cost of production when compared with the obtained net returns with an acceptable MRR An increase in output will always raise profit as long as the marginal rate of return is higher than the minimum rate of return 100% [48]. [63] where plant height correlated positively with seed, straw and biomass yield.…”
