Effect of Pre-Sowing Seed Treatment of Selected Organics and Botanical on Growth, Seed Yield and Yield Attributting Tarits of Maize (Zea mays L.) Var. VNR-4226

Abstract

The field experiment was conducted during Kharif season in the year 2021- 2022 at post graduate Crop research farm, Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, in order to study the different Pre-sowing seed treatments of selected Organics and Botanicals on growth, Seed yield and yield attributing traits of Maize (Zea mays L.) Var. VNR-4226 The experiment was laid out in Randomized Block Design (RBD) with 13 treatments and 3 replications. In order to standardization method of seed treatment to specific maize crop and they were evaluated by screening a range of duration and concentration Viz T0- Control, T1 - Panchagavya 5% (12Hrs), T2 - Panchagavya 10% (12Hrs), T3 - Panchagavya 15% (12Hrs), T4 - Moringa Leaf Extract 5% (12Hrs), T5 - Moringa Leaf Extract 10% (12Hrs), T6 - Moringa Leaf Extract 15% (12Hrs), T7 - Vermiwash 5% (12Hrs), T8 - Vermiwash 10% (12Hrs), T9 – vermiwash 15% (12Hrs), T10 – Moringa leaf extract 5% (12Hrs), T11 - Moringa leaf extract 10% (12Hrs), T12 - Moringa leaf extract 15% (12Hrs). To find out effect of different seed treatment on growth, yield and seed quality parameters of maize showed that significant treatment for Rate of Field emergence, Plant height (30,60,90 DAS), Number of leaves (30,60,90), Days to 50% Tasselling, days to 50% Silking, days to 50% Maturity, Number of cobs in a plant, cob length, cob grith, Number of rows in a cob, Number of Kernels in a row, Total number of kernels in a cob, seed yield per plot, Biological yield, Stover yield, Harvesting Index and economics were significantly recorded highest in T12 (Neem leaf extract 15% for 12 hours) followed by T2- Panchagravya (10%) whereas minimum was observed in T0 (control).

Impact of Pre-Sowing Seed Treatments on Sweet Corn Landraces under Moringa leaf extract

“…Also, seed priming with hydro or halo treatments may have stimulated early development and hastened the silking process in sweet corn (El-Sanatawy et al, 2019). Moringa leaf extract, at both concentrations, positively affected the promotion of early silking in sweet corn (Yeruva et al, 2022). The results are presented as mean based on n=3, LSD=Least significant difference at (P<0.05).…”

Correlation between Rice Weevil Infestation Sitophilus oryzae (Linnaeus) and Seed Quality Parameters of Maize (Zea mays. L) Seed

“…During storage maize seeds are damaged by many insects and pests which causes both qualitative and quantitative losses in tropical zones this damage is about 20-30% [3]. Among the various stored product insects infesting maize, S. oryzae is one of maize's most critical, internal feeding pests and one of the most important stored product pests [4,5]. The management of quality should consider insect population fluctuation to establish an appropriate control [6,7].…”
