“…The highest values were obtained when half FYM was used in conjunction with either half RNP or half blended fertilizer over RNP. Similar findings on AE of P were reported when P supplied from organic and inorganic sources and the authors stated that AE of P decreased when P fertilization increased [9,20,23].…”

“…Uptake of N use efficiency and concentration was done separately for shoots (stems and leaves), roots plus stolen. The nutrient accumulation and partitioning were calculated by multiplying nutrient concentration with the dry matter of the respective plant parts and the uptake of N in economic and by-product of potato plant parts were estimated following the procedure outlined [8,9].…”

Phosphorus is often an important limiting factor for crop yields, and in addition, low soil fertility and crop nutrient imbalances are major obstacles preventing Ethiopian farmers from realizing high agricultural productivity. Effect of the sole and combined application of farmyard manure (FYM) and inorganic fertilizers on tuber yield, nitrogen (N) uptake and use efficiency of Irish potato (Solanum tuberosum L.) was assessed in a field experiment carried out in Arbegona district of Sidama zone in Southern Ethiopia. The studied nutrient management practices were control (without fertilizer) and farmyard manure (FYM), recommended N and phosphorus (P), blended (17.3 N 3 , 4.7 P 2 O 5 , 7.41 S 2 , 23 Zn0, 3 B within 100 kg) plus potassium (K) fertilizers and combined half FYM and recommended NP and combined half FYM and blended plus K fertilizer. Treatments arranged in randomized complete block design with three replications. The experimental soil was loamy and very strongly acidic, low in organic carbon and available P and medium in total N and available K. Results showed that the applied FYM and inorganic fertilizer individual and in combination were resulted positive N balances. Potato plants amended with sole blended fertilizer, combined half recommended NP and FYM, and combined half FYM and blended fertilizers improved total dry tuber yield and total N uptake more than twofold (100%) as compared to the control. In the amendments, average agronomic and physiological efficiency of N supply and uptake were 48 and 46 kg dry tuber, respectively. Furthermore, 112% of apparent recovery efficiency of N was obtained across the treatments. Soil amendments resulted the highest net benefits with acceptable marginal rate of return (above 100%). Generally, soil amendments either in sole or combined inorganic and organic fertilizers could be considered to improve soil fertility status and potato yield in the study area.

Potassium is the key element for mungbean (Vigna radiata L.) productivity. The study was carried out to understand the effects of potassium (K) on mungbean productivity, quality, nutrient content and nutrient uptake and how this element can help to manage soil fertility.Therefore, an experiment was conducted during two consecutive years 2016 and 2017. The experiment was laid out in randomized complete block design considering six treatments with thrice replicates. The treatments were T1 = Control, T2 = 30 kg K ha-1, T3= 40 kg K ha-1, T4= 50 kg K ha-1, T5= 60 kg K ha-1 and T6= 70 kg K ha-1 along with the blanket dose of N15P20S10Zn2B1.5 kg ha-1. Results revealed that application of different levels of potassium showed significant effects on the plant height, number of pods per plant, number of seeds per pod and thousand seed weight which were influenced to obtain higher yield of mungbean. The highest average seed yield (1476 kg ha-1) and highest yield increment (39.5%) of mungbean were produced from the treatment T5. Most of the cases the highest nutrient (N, P, K, S, Zn and B) content was obtained in T5 treatment.The highest K uptake by mungbean, maximum nodulation, the highest protein content in seed and maximum apparent K recovery efficiency (54.8%) were, however, recorded from the treatment receiving of 60kg K ha-1. It was concluded that proper use of K with other nutrients facilitated to improve the productivity and quality of mungbean and also K played a significant role in maintaining soil fertility.
