Abstract

Nutrient mining due to sub optimal fertilizer use in one hand and unbalanced fertilizer (only N and P) uses on other has favored the emergence of multi nutrient deficiency in Ethiopian soils. This problem demands different studies to balance the nutrient combination to improve potato yield and quality. A trial was conduct to evaluate different fertilizer types for potato production and to enrich its quality in Southern Ethiopia during the main cropping season of 2016 and 2017. Fertilizer treatments were based on limiting nutrients of the area including N, P, K, S, B and at different rate and cobination. The trial consists of ten treatments (1) no fertilizer (control) (2) NPSB: 69 kg N + 23.5 kg P + 10 kg S + 1.07 kg B/ha (3) NPSB: 92 kg N + 31 kg P + 13 kg S + 1.4 kg B/ha (4) NPSB: 115 kg N + 39 kg P + 17 kg S + 1.7 kg B/ha (5) NPSB: 138 kg N + 47 kg P + 20 kg S + 2.0 kg B/ha (6) NPSBCu: 69 kg N + 31 kg P + 17 kg S + 1.4 kg B + 0.625 kg Cu/ha (7) NPSBCu: 92 kg N + 39 kg P + 10 kg S + 1.7 kg B + 0.625 kg Cu/ha (8) NPSBCu: 115 kg N + 39 kg P + 10 kg S + 1.7 kg B + 0.625 kg Cu/ha (9) NPSBCu: 138 kg N + 39 kg P + 10 kg S + 1.7 kg B + 0.625 kg Cu/ha and (10) NPS: 112 kg N + 40 kg P + 17 kg S/ha was used as positive control.

Effect of sulphur and zinc fertilization on yield, uptake and nutrient-use efficiency of sesame (Sesamum indicum) || PINKY YADAV1, S.S. YADAV2, KAMAL GARG3, L.R. YADAV4, S.K. YADAV5 AND RAM KRISHNA SHEKHAWAT6 ||A field experiment was conducted at Agronomy Farm, S.K.N. College of Agriculture Jobner, Jaipur (Rajasthan) during the rainy (kharif) season of 2018, to study the effect of 4 levels of each sulphur (0, 15, 30 and 45 kg sulphur/ ha) and zinc (0, 10, 20 and 30 kg zinc sulphate/ha) fertilization on yield, uptake and nutrient-use efficiency of sesame (Sesamum indicum L.). Results showed that progressive increase in level of sulphur up to 30 kg/ha, being at par with 45 kg, significantly increased the most of the yield-attributing characters of sesame and increased N, P, S and Zn uptake. It also recorded significantly higher seed (712 kg/ha), stover (2345 kg/ha) and biological yield (3056 kg/ha) of sesame over control and 15 kg S/ha. The maximum sulphur-use efficiency was recorded when its level was raised from 0 to 15 kg/ha and various levels of sulphur brought significant effect on zinc-use efficiency. Successive increase in level of zinc sulphate up to 20 kg/ha significantly improved most of the yield-determining characters and N, P, S and Zn uptake by sesame over lower levels and found at par with 30 kg/ha. It also recorded significantly higher seed (725 kg/ha), stover (2307 kg/ha) and biological yields (3032 kg/ha) over the control and 10 kg/ha, and found at par with 30 kg zinc sulphate/ha. Raising the zinc level from 0 to 20 kg/ha and 0 to 10 kg/ha, registered the highest sulphur- and zinc-use efficiency, respectively. Application of 30 kg S/ha in conjunction with zinc sulphate at 20 kg/ha (S30 Zn20), was the most effective treatment combination for obtaining higher seed yield (802 kg/ha), nutrient uptake and net returns (`48,970/ha) in sesame. ||Key words: Nutrient uptake, Nutrient-use efficiency, Sesame, Sulphur, Yield, Zinc.
