“…The pungam leaf powder pelleting treatments might have helped in absorbing more soil moisture and nutrients, thus enabling better growth resulting in higher yield (Sai Pradeep Kumar, 2015). Similar observations with increased yield parameters due to seed pelleting under saline condition were reported by Harish Babu et al(2005 and Prakash et al (2018). Increased pod yield was observed which may be due to the translocation of sugars from complex compounds like carbohydrates which are translocated at greater rate as reported by Dileepkumar et al (2009).The influence of seed hardening with CaCl 2 and KCl observed in present results are in line with the reports of Mishra and Dwivedi (1980) and Sen and Misra (1987).…”

“…Similarly, increased gas exchange parameters due to flyash treatment was reported by Anbarasan (2011) in cowpea. Prakash et al (2018) found that plants treated with pungam leaf powder @ 150 g kg -1 recorded more photosynthesis, transpiration rates and stomatal conductance. Increase in gas exchange parameters might be due to increased enzyme activity, chlorophyll content and presence of growth promoting substances like GA 3 which leads to more production of photo-assimilates and better growth and development (Prakash et al, 2018).…”

The pungam leaf powder pelleting might have triggered enhanced protein synthesis, which in turn could have contributed to the amino acid rescue and protein turnover during active metabolism, later in plant life (Prakash et al, 2018).…”

“…Seed pelleting with botanicals has gained importance nowadays due to their anti oxidant property and presence of various alkaloids like pinnalin, pongamol, saponin, -sitosterol and tannins as in case of pungam leaf extract (Singh, 1982;Savita Sangwan et al, 2010). Use of leaf powders of pungam (Pongamia glabra), prosopis (Prosopis juliflora), notchi (Vitex negundo) and arappu (Albizia amara) as pelleting agents enhanced the seedling vigour and crop yield in many crops (Bhattacharya et al, 2015;Pushpakaran et al,2018;Prakash et al, 2018 ).…”

Background: Cowpea (Vigna unguiculata) is one of the most important legume crops cultivated throughout the world. Cowpea is used as food, feed, forage, fodder, green manuring and vegetable. It’s seed is a nutritious component in the human diet, as well as for livestock. Seed hardening and pelleting are seed enhancement techniques used to improve seed germination and seedling vigour and growth by altering the physiological state of the seed. This alteration may improve the vigor or the physiology of the seed by enhancing uniformity of germination. Seed enhancement techniques like hardening and priming include use of chemicals that trigger systemic acquired resistance or improve stress tolerance whereas the pelleting treatments improve seed handling and planting. They also enhance nutrient availability or provide inoculates by delivering materials needed during sowing, germination and seedling establishment. Hence in order to study the combined effect of seed hardening and pelleting on growth, yield and resultant seed quality of cowpea under natural saline conditions, the present study was taken up. Methods: The present field and laboratory investigations were carried out to study the effect of seed hardening, seed pelleting and their combined effect on growth, physiology, yield and resultant seed quality of cowpea under natural saline conditions. The fresh seeds of cowpea seeds cv. CO (CP) 7 were hardened with KCl @ 1%, CaCl2 @ 1% and both KCl and CaCl2 @ 1% and then the hardened seeds were further pelleted with pungam leaf powder @ 100, 150 and 200 g kg-1 of seed. Then the treated seeds were evaluated for their seed productivity and resultant seed qualities using untreated seeds as control. Observations on growth, leaf chlorophyll content, gas exchange parameters, yield and resultant seed quality parameters were recorded. Result: The experimental results revealed that among the treatments, seeds hardened with KCl @ 1 % + CaCl2 @ 1 % and pelleted with pungam leaf powder @ 200 g per kg recorded higher growth, yield parameters, leaf chlorophyll content, gas exchange parameters and resultant seed quality when compared to control and other treatments.

Background: Onion (Allium cepa L.) is a major bulbous vegetable as well as condiment of family Alliaceae grown in India, originated in Iran and Pakistan. Seed pelleting is a mechanism of applying various materials to the seed that can enhance the seed quality with respect to physiological, physical and health attributes. Seed pelleting make it easy to handle small and irregular shaped seeds.Methods: The present investigation was conducted in the field of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan during seasons of 2016-17 and 2017-18. Result: This experiment comprised of pelleted seeds with different botanicals carried out to determine the effect of sowing dates and seed pelleting and their interactions on plant growth, yield and quality of bulb crop. All the factors in the experiment as well as their interactions showed significant influence on plant growth, yield and yield contributing characters in onion. The seeds pelleted with Azadirechta indica leaf powder + clay and Melia azedarach leaf powder + clay sown directly showed maximum values w.r.t. emergence (91.50 %), plant height at 60 days after sowing (35.35 cm), average leaf length (38.43cm), number of leaves per plant (8.67), number of days to harvesting (233.49), polar diameter (46.72 mm), equatorial diameter (57.77 mm), bulb size index (2699.74 ), neck thickness (12.12 mm), number of bulb per plot (89.00) average bulb weight (75.24 g), bulb yield (6.67 kg per plot or 400.01 q per ha), plant height before neck fall stage (58.55 cm). From the present studies, it can be concluded that onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azedarach leaf powder + clay showed significant effects for enhancing bulb quality, growth, quality and yield of bulb crop raised through direct seeding.

Background: Seed pelleting involves the sticking of target materials on to the surface of seeds. Pelleted seeds make planting of small seeds much easier by altering their shape, size and density. The call out on organic farming explains the requisite of user friendly and ecofriendly technique for seed management practices. The current study aimed to assess the effect of organic manure seed pelleting for enhancing soil properties, nutrient uptake and yield of rice.Methods: A pot culture experiment was carried out at College of Agriculture, Vellayani during the year 2018-19 to prepare organic manure seed pellets for rice and to evaluate its influence on yield, nutrient uptake and soil nutrient status. Pelleting materials were prepared using various treatment combinations namely, FYM + Azospirillum + Phosphobacteria (T2), vermicompost + Azospirillum + Phosphobacteria (T3), bioslurry flakes + Azospirillum + Phosphobacteria (T4), charcoal powder + Azospirillum + Phosphobacteria (T5), fly ash + Azospirillum + Phosphobacteria (T6), pongamia leaf powder + Azospirillum + Phosphobacteria (T7) and bioslurry + plant extracts + Azospirillum + Pseudomonas (T8: Farmer practice).Result: The results revealed that the highest grain yield (54.84 g pot-1) and straw yield (66.10 g pot-1) were recorded by T3. With regard to the uptake of nutrients, T3 registered the highest uptake of N, K, Ca, S, Zn, Cu and Si in grain and shoot. P uptake in grain was highest in the treatment T4 while T3 had the maximum P uptake in shoot. Nutrient status of the post-harvest soil was significantly influenced by the treatments.
