“…The lower PE might indicate that the crop did not utilize the absorbed N for the production of maximum pod yield. Related findings on PE of N on potato were reported by Banerjee et al (2015). The authors indicated that at high uptake of N the PE decreases a luxury consumption of N that might not contribute to physiological processes.…”

A field experiment was conducted to evaluate the effects of different blended fertilizer types (NPSB and NPSBZn) and their rates on fruit yield, nutrient concentration, nutrient uptake and nutrient use efficiency of hot pepper at Assosa, Western Ethiopia. The experiment was set with eight treatments (recommended NP, three different blended rates for each NPSB and NPSBZn and unfertilized plot) laid out in randomized complete block design with three replications using a hot pepper variety Mereko Fana. In the blends since N content was low, supplementary N was applied from Urea to optimize N needs of the crop. The results of the study revealed that the crop phonological parameters (days to flowering and maturity, fruit dry yield and average dry fruit weight) were significantly (p<0.05) affected by blended fertilizer type and rates. The days to flowering and maturity were significantly (p<0.05) improved by application of 100 kg NPSBZn + 29 N kg ha-1. The maximum total dry fruit yields (2.44 t ha-1), the highest fruit uptake of nitrogen (50.1), phosphorus (9.9) and sulfur (4.1 kg ha-1), and the highest apparent nutrient recovery for N (47.91%) were recorded with the application of 150 kg + 44 N kg ha-1 NPSBZn; while higher agronomic efficiency of N (9.59 kg pod kg-1) and P (12.80%) were recorded with the application of 100 kg + 29 N kg ha-1 blended fertilizer rate. In general, the nutrient use efficiency of the blended fertilizers tested was acceptable and high. The uptake of N, P, K and S were significantly and highly correlated (p< 0.01) with total dry fruit yield. Therefore, the study recommends 150 kg NPSBZn + 44 N kg ha-1 blended fertilizer for sustainable hot pepper production in Assosa area of Western Ethiopia.

“…This is in line with the study of (Badr et al, 2012). On the contrary, Banerjee et al (2015) found out that NUE decreased with an increase in N rate. For the interaction, the highest value of NUE was recorded at FI×N3 (236.44 kg/N kg) whereas the latest was obtained from RF×N1(56.30 kg/N kg) (figure 2k and l).…”

BackgroundThe yield of potato (8.86 tonnes/ha), the second staple food and cash crop in Kenya is remained low due to a reduction in seasonal precipitation and low soil fertility. Drought or dry periods between rainfall seasons and increased temperatures, which leads to high crop evapotranspiration, are experienced in 70-80% of the smallholder farms. Among major elements require by potato, nitrogen is the most important influential element but it is deficient in most potato-growing soils in Kenya because of nutrient depletion with inadequate nutrient replenishment results from continuous production. Hence the introduction of supplemental irrigation with an adequate application of this nutrient could increase crop yields. Therefore, this study was conducted in Nakuru, one of the major potato growing areas in Kenya, to determine the effects of full supplemental irrigation (FI) and four nitrogen levels, N0(0), N1(60), N2(90) and N3(130 kg N/ha) on tuber yield, water use efficiency (WUE) and nitrogen use efficiency (NUE) of potato grown in a mollic Andosol in Kenya compared to conventionnel rain-fed potato production. Results The results showed that tuber yield, marketable tuber yield and NUE significantly differed due to the interaction effect between irrigation and N-fertilization rate (P<0.001) whereas the WUE was statistically different due to the N-fertilization rate (P<0.001). The highest tuber yield 58.28 tonnes/ha was found in supplemental irrigation with an application of 130kg N/ha treatment. Full supplemental irrigation treatment increased marketable yield by 129.84, 94.63, 151.21 and 126.63% for 0, 60, 90 and 130 kg N/ha, respectively compared to rain-fed N-fertilization treatments. NUE increased statistically with an increase in N rate up to 90 kg N/ha, then tended to increase slightly as nitrogen rate increased further. An increase in potato tuber yield was positively correlated with number of tubers/plant (r=0.75), NUE (r=0.95), WUE (r=0.72) (P < 0.001).ConclusionsThe high potato yield and marketable tuber yield in mollic Andosol can be obtained when all water deficits of the growing season are eliminated with supplemental irrigation and an application of 130kg N/ha but it is essential to exploit water regimes for acceptable yield with water-saving.

“…These authors showed that at high P uptake the PE of crops decreases and the PE of P would depend on varieties. Nutrient efficiency of plants depends on: soil factor of production potential, chemical species of the fertilizer used and plant factors of interaction with environmental factor and root microbe [20,22,24].…”

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.
