“…Total cost of cultivation( /ha) Maximum chlorophyll content in leaves of ashwagandha might be due to increased nutrient content, rapid mineralization, optimum C/N ratio and more availability of nitrogen supplied by poultry manure along with biofertilizers, leading to better vegetative growth and yield [10]. These results are in accordance with the findings of Deshpande et al [11] and Onwu et al [12] in okra.…”

The present investigation entitled Effect of different organic sources of nutrients on quality and economics of ashwagandha [Withania somnifera (L.) Dunal] was carried out during Kharif 2021-22 at College Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Dist. Mehsana, Gujarat. Experiment was laid out in randomized block design with three replications and twenty treatments viz., T1: 100% RDN through FYM; T2: 100% RDN through Vermicompost; T3: 100% RDN through Neem cake; T4: 100% RDN through Poultry manure; T5: 80% RDN through FYM; T6: 80% RDN through Vermicompost; T7: 80% RDN through Neem cake; T8: 80% RDN through Poultry manure; T9: 60% RDN through FYM; T10: 60% RDN through Vermicompost; T11: 60% RDN through Neem cake; T12: 60% RDN through Poultry manure; T13: 80% RDN through FYM + Azotobacter + KSM + PSB; T14: 80% RDN through Vermicompost + Azotobacter + KSM + PSB; T15: 80% RDN through Neem cake+ Azotobacter + KSM + PSB; T16: 80% RDN through Poultry manure + Azotobacter + KSM + PSB; T17: 60% RDN through FYM + Azotobacter + KSM + PSB; T18: 60% RDN through Vermicompost + Azotobacter + KSM + PSB; T19: 60% RDN through Neem cake + Azotobacter + KSM + PSB; T20: 60% RDN through Poultry manure + Azotobacter + KSM + PSB. Maximum chlorophyll a, b and total at 90 DAS (at full bloom stage) (1.92, 0.75 and 2.11 mg/g, respectively) and withanolides content (0.32%) at harvest were recorded with treatment T16. The maximum net income (₹ 1,38,707/ha) and benefit cost ratio (3.52) were also obtained in same treatment. Therefore, it can be concluded that the application of 80% RDN through poultry manure + Azotobacter + KSM + PSB (T16) was found beneficial for obtaining higher yield of better quality and economic returns in ashwagandha.

“…Pseudomonas is denominated as a Plant Growth Promoting Rhizobacteria (PGPR) because it is able to colonize the rizosphera of plants (bacterias have to colonize the plant endosphere after colonizing the rhizosphere to confer some benefits to the plant [28]) and to present antagonistic activity toward diverse pathogens [29]. Recently, [12] recognized that beneficial Pseudomonas strains are frequently found associated with plants where they act as PGPB and the biofertilizer liberates growth promoting substances and vitamins that helps in maintaining the soil fertility; these authors confirmed that they acts as antagonists and suppress the incidence of soil borne plant pathogens. On the other hand, [30] emphasized that microorganisms, as a general concept, are one of the most important organisms that can develop beneficial associations with plants.…”

“…Other bioproducts, such as: Fitomas ® [9], VIUSID agro ® [10] that stimulate vegetative development are also used successfully. Many studies have been carried out on sweet potato growth and productivity, including the effect of organic and inorganic fertilizers applications ( [11]; [12]. Among the most important beneficial microorganisms, different bacterial species of the genus Pseudomonas have been described; they act in a double way on crops: they promote plant growth and suppress pathogenic microorganisms.…”

A field experiment was conducted to study the effect of a Pseudomonas fluorescens-based biofertilizer on sweet potato (Ipomoea batatas (L) Lam) yield. The application was by immersion of cuttings before sowing for 0, 5, 10 and 15 minutes with combination doses of 0, 50 and 100% of NPK mineral fertilizer in a randomized block design with three replications (12 treatments-combinations). During the harvest (130 days after planting), some measurements related to yield components were recorded on ten randomly selected plants from each plot. All treatments with Pseudomonas’ immersion showed a positive productive response. With 100% NPK and the immersion in the biofertilizer for 15 min showed the highest yield (56.09 tha-1), followed by the other treatments with 100% NPK and without statistical differences among them. The treatment with 50% NPK and the immersion in Pseudomonas for 15 min (49.58 tha-1) had no statistical differences with the control variant (100% NPK, 51.60 tha-1). Based on the results, it can be concluded that this biofertilizer could be an appropriate alternative to increase the sweet potato yield, saving the 50% of the current quantity of the recommended mineral fertilizer, through a more friendly environmental techniques to promote a sustainable, efficient and productive agriculture.

“…(Gao et al 2020;Mpanga et al 2018;Radziah and Saad 2009). Biofertilizers can also protect against some soilborne diseases (Singh et al 2020). The application of biofertilizers in this study can improve the growth rate and yield of sweet potatoes.…”

Abstract. Nafi'ah HH, Hindersah R, Mubarok S, Maulana H, Suganda T, Concibido V, Karuniawan A. 2021. Growth rate and yield response of several sweet potato clones to reduced inorganic fertilizer and biofertilizer. Biodiversitas 22: 1775-1782. Sweet potato has a high economic value because it is often utilized for staple food and industrial raw materials. Balanced fertilization, including inorganic and biofertilizer, is needed to enhance the production of sweet potatoes. Two-year field experiments conducted at two different agro climates were performed to determine the best response of growth rate and yield of sweet potato to reduced inorganic fertilizer and biofertilizer application rates. Three sweet potato clones, Mencrang, Biang, and Rancing, were grown with a combination of inorganic and biological fertilizers in a randomized complete block design of three replications. Results showed that Biang and Rancing have the best response under reduced inorganic and biofertilizer application rate. The application of biofertilizer enabled the reduction of inorganic fertilizer use but still resulted in increased growth rate and tuber yield of potatoes in both locations. However, the application of biofertilizer did not increase the total soluble solids, which is the main indicator of sweetness in sweet potato.
