Studies were carried to find the effect of pre - sowing seed treatments on field emergence and seedling growth of palmyrah. The seeds were subjected to water soaking for 24 hours, soaking in 1% and 2% of cow dung solution, KNO3, H2O2 and CaOCl2 for 24 hours and dry seeds served as control. 120 days after sowing the observations were made on days taken for initial emergence, field emergence (%) and 210 days after sowing the observations were made on field emergence (%), seedling height (cm) and number of leaves per seedling. The results revealed that seeds soaked in 1% cow dung solution for 24 hrs took 102 days for initial emergence followed by seeds soaked in 1% CaOCl2 for 24 hrs (103 days), 210 days after sowing the seeds soaked in 1% CaOCl2 for 24 hrs. recorded the highest field emergence of 56 % and more number of leaves/seedling (2.1) when compared to control. It is recommended that palmyrah seeds soaked in 1% CaOCl2 for 24 hrs enhance the germination, field emergence and seedling growth.

This study investigated the effects of potting media on seed germination and early seedling growth of Pterocarpus erinaceus Poir at the Forestry Nursery in Jos, Nigeria. Using Completely Randomized Design (CRD) with three replicates, laboratory-tested soil samples, top soil, sharp sand, sharp sand + top soil, sharp sand + top soil + cow dung and sharp sand + top soil + poultry droppings were used in various combinations to assess the growth parameters of P. erinaceus (germination percentage, emergence, plant height, number of leaves, length of leaves and stem diameter) for 12 weeks. Descriptive and inferential statistics were employed to analyze collected data. Result indicated that sharp sand + top soil + poultry droppings had the highest nitrogen concentration (2.19%), sharp sand + top soil + cow dung (2.07%), sharp sand + top soil (1.50%), top soil (0.72%) and Sharp sand (0.38%). Potting media with poultry droppings recorded an overall higher percentage germination of 42.9% by the end of the germination period. Analysis of variance (ANOVA) of collected data on combined soil aggregate on growth parameters indicated a significant (p<0.05) difference in plant height, number of leaves, leaf length and stem diameter. Potting with poultry dropping gave the best potting media growth results when compared to other treatments that enhanced seed germination and seedling growth of P. erinaceus. This superior observation of the poultry droppings incorporated potting mixtures over the cow dung provides an outstanding potentials to enhance P. erinaceus plantation establishment. Consequently, recommended for raising seedlings in the nursery as well as ensuring sustainable management.

Background: Sarpagandha is an indigenous medicinal herb of Indian continent. It has many medicinal properties. Due to increasing demand of Sarpagandha, its exploitation is increasing continuously but for lack of cultivation, this plant has been listed in endangered category. Commercially, it is propagated through seeds but the main barrier of seed propagation is its irregular and low germination. Hence, the current study was undertaken to study the effect of growing media and seed treatment methods on seed germination and seedling growth of Sarpagandha to eliminate the inhibitory effect of the hard stony endocarp.Methods: Seed germination and seedling growth experiments of Sarpagandha were carried out with following different seed treatments, T1 (Control), T2 (Water soaking for 24 hours), T3 (water soaking for 48 hours), T4 (Water soaking for 24 hours + cotton cloth wrapping for 24 hours), T5 (GA3 200 ppm), T6 (FYM treatment for 24 hours), T7 (FYM treatment for 48 hours), T8 (Hot water treatment) and T9 (Cow dung treatment for 24 hours). Experiment was laid out in CRD. The data recorded on the various parameters were analyzed at 5% level of significance by using ANOVA.Result: Results indicated highest germination percentage (51), lowest mortality percent (49), minimum days for initiation of germination (23), minimum days taken for germination completion (33), highest speed of germination (3.77), maximum vigour index (1441.44), highest root (11.27 cm) and highest shoot length (17 cm) in T5 (GA3 200 ppm) followed by T3 (water soaking for 48 hours). Indicating, T5 (GA3 200 ppm) to be best seed treatment for higher germination and subsequent seedling growth of Sarpagandha (Rauvolfia serpentine L.).

Study Design: Comparative effects of different organic manures on the seedlings growth of Massularia acuminate. Place and Duration of Study: Forestry Research Institute of Nigeria, between February, 2019 and August 2019. Methodology: Various concentrations of different types of organic manures; poultry manure, cow dung and horse dung were mixed with the topsoil separately to raise the seedlings of Massularia acuminata, comparative seedlings height growth, the stem diameter growth and the number of leaves per seedlings were examined to determine the development of the seedlings. Results: The results revealed that, organic manure application generally enhanced the growth of the seedlings, improved seedlings height, number of leaves and collar diameter. Also, with increasing rate of application of organic manures from 0 g to 50 g per seedlings, all seedlings growth parameters were improved. 10 g and 30 g manure had significant effects on plant growth with seedlings height 15.29 cm and 15.10 cm, number of leaves per seedlings (19.80 and 19.43) and collar diameter (6.58 mm and 6.57 mm) with Q2 and Q3 respectively as compared with the control (5.18 mm). Highest seedling growth was observed in poultry application with seedlings height 14.42 cm, number of leaves (19.63) and collar diameter (6.31 mm). Conclusion: The use of poultry manure and cattle dung at increased concentrations of 10 g and  30 g are recommended to be beneficial for sustainable healthy seedling production.

The experiment was conducted in post graduate Seed Testing Laboratory and Field Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P) during Rabi season 2020-2021, in order to standardize the suitable pre-sowing seed treatment for Lentil (K-75). Different pre-sowing seed treatments viz.,T0-Control (untreated), T1- KCL @1%, T2- KCL @ 3%, T3- KNO3 @ 1%, T4- KNO3 @ 3%, T5- Panchagavya @ 2%, T6 – GA3 @ 20ppm, T7 – Panchagavya @ 4%, T8 – GA3 @ 10ppm,T9 – Panchagavya @ 6%,T10 – Tulasi Leaf Extract @ 2%, T11 – Tulasi Leaf Extract @ 4%,T12 – Tulasi Leaf Extract @ 6% were evaluated by screening of 12 hour. It was found that all the pre-sowing seed treatments recorded the significant difference with that of control. In field condition highest field emergence percentage,yield and yielding attributes was found in T7 -Panchagavya @ 4%. Pre-sowing seed treatment with Panchagavya @ 4% followed by GA3 @ 10 ppm, Panchagavya @ 2%, KCL @ 1% significantly increased the germination and yielding attributes of Lentil. Pre-sowing seed treatments with Panchagavya (4%) and GA3 (10ppm) resulted in maximum increase in field emergence, vigour of Lentil seeds and found to be lowest in control seeds. Pre-sowing seed treatment that leads to a physiological condition that allows the seed to germinate more effectively and no costly equipment and chemical requirements could be used. Hence it is a simple method for overcoming weak germination and seedling establishment and helps to preserve agriculture and economical, non-toxic, eco-friendly sources.

Iprodione or vinclozolin dusted on White Spanish and Goldberg onions, at 100g a.i./kg of seed, reduced germination by at least 40% and severely stunted the growth of seedlings nated on moistened filter paper. Similar rates of vinclozolin severely reduced field emergence and retarded the growth of White Spanish and Goldberg seedlings whereas the same rate of iprodione reduced field emergence and growth of Goldberg, but not White Spanish. Poor field emergence of treated seed could have been a germi consequence of inhibition of germination, stunted seedling growth or a combination of both factors.
