Other claims from this paper (11)
- Intervention effect Increasing nitrogen levels significantly increased average tuber weight, total tuber yield and shoot dry yield of potato.
- Intervention effect Foliar application of Fe, Zn and Mn increased tuber and shoot yield of potato only.
- Intervention effect 200 kg N per feddan combined with T3 gave the heaviest tubers of potato, 219.0 g and 229.2 g in the first and second seasons.
- Association The interaction of N levels and foliar micronutrients had no significant effect on tuber dry matter, protein and starch %.
- Association Uptake of N, P and K significantly increased with increasing N levels and micronutrient concentration.
- Association The interaction effect on uptake of N, P and K was not significant.
- Association N utilization efficiency and N uptake efficiency decreased with increasing N levels.
- Association N level of 200 kg N per feddan gave the highest N apparent recovery fraction in both seasons.
- Association Interactions of N levels and foliar Fe, Zn and Mn affected N utilization efficiency, N uptake efficiency and N apparent recovery fraction.
- Association The highest N apparent recovery fraction, 37.13% and 40.55% in the first and second seasons, occurred with 175 and 200 kg N per feddan and foliar Fe, Zn and Mn at 1.25 g/L.
- Association The interaction effect of N level and macronutrients on the above mentioned parameters was not significant.
