Response of sunflower varieties to NPK fertilization

Abstract

This study was executed at Agriculture Research Institute (ARI) Tarnab (Peshawar) to evaluate the response of sunflower varieties (hybrids) to different combinations of Nitrogen, Phosphorus and Potash (NPK). Four sunflower varieties (hybrids i.e Aritar-93, Peshawar-93, Hysun-33 and SF-187) were sown with five levels of NPK (40:40:40, 80:50:50, 120:60:60, 160:70:70 and 200:80:80 kg ha -1 ) using two factorial randomized complete block design with three replications. With the increase of NPK levels, significant increase for disc diameter (13%), plant height (4%), days to maturity (8%), 1000 grain weight (9%), biological yield (20%) and grain yield (12%) were recorded with the exception of filled grain head -1 . Better performance was observed for 200-80-80 kg ha -1 NPK than the rest of the fertilizer treatments. The interaction between fertilizers and varieties (F × V) had non-significant effect on all parameters; however, varieties were significantly different from one another. Hybrids i.e SF-187 and Hysun-33 performed best among the four hybrids in all parameters with yield capacity of 1408 and 1267 kg grain ha -1 respectively. Thus it is suggested to apply NPK at the rate of 200-80-80 kg ha -1 to hybrids SF-187 and Hysun-33 for obtaining good yield of sun flower among the studied combinations.

Response of Two Sunflower (Helianthus annuus L.) Genotypes to Foliar Application of Different Nano Fertilizers.

“…In general, differences between the two locations may be due to soil properties and environmental conditions (Table 1 and fig1). This result agrees with (Ahmad et al, 2017).…”

“…The maximum mean value of seed index was founded for (Velko * Super-Nano) at Ranya and Saruchawa locations as compared to the control treatment. Similar results were obtained by Ahmad et al, (2017) they notcied the role of fertilization by NPK on the interactions with sunflower variety, the evidence from the interaction treatment between Fertilizer × Varieties caused maximum value (53.23 g) which noted for variety SF-187 and NPK at the rate of 200-80-80 kg ha -1 . While the minimum weight of a thousand seeds (38.63 g) was noted for the Peshawar-93 variety that was given NPK dose at the rate of 40-40-40 kg ha 1 .…”

Performance of Linseed (Linum usitatissimum L.) Varieties in Foothills of Nagaland under Irrigated Condition

“…This may be also due to favourable environment and photosynthesis activity which increased the accumulation of dry matter in the plant. This finding is in consensus with those of Ahmad et al (2017) and Emam (2019). The data revealed that harvest index in variety T-397 (39.56%) was significantly higher and was at par with variety JLS-95 (38.38%), RLC-153 (37.08%), Parvati (37.79%) and it was found minimum with variety LSL-93 (32.43%) which was at par with variety Shekhar (34.14%) and Priyam (34.07%).…”

In vitro Genotoxicity and In silico Docking Analyses of the Essential Oils of Thuja orientalis

“…[14] It has been stated that extracts obtained from this plant affect seed development, germination rates of seeds, and root development. [15] Thuja orientalis is also a plant cultivated primarily for making hedges in parks and gardens and is also used for lumber, construction stakes, railroad ties, musical instruments, and canoe building. [16] Moreover, it contains essential oils that are used for medicinal purposes, including homeopathy and the treatment of diseases such as bronchial catarrh, enuresis, cystitis, psoriasis, rheumatism, and shingles, as well as in various forms of traditional medicine.…”
