​Efficiency of Biocomposted Agroindustrial Wastes and Their Response in the Growth and Yield of Vigna unguiculata (L.) Walp

Abstract

Background: Agroindustrial by-products of cocoa shell and jack fruit peels generally considered as organic waste have almost no economic value and create a big problem in disposal time. A significant amount of biocomposted cocoa shell and jack fruit peel waste is used as organic manure that enhances growth in Vigna unguiculata (L.) Walp. Methods: This research work was conducted in the period of 2019 in the Department of Botany, Avinashilingam Institute for Home Science and Higher Education for Women, Coimbatore, Tamil Nadu (India). A large amount of cocoa shell and jack fruit peel waste was used for the biocompost preparation using Pleurotus eous, Pleurotus florida spawns and Eudrilus eugeniae. After 90 days, biocompost were taken and sieved used as manure for plant study. Eight different treatments were carried out for the cultivation of Cowpea. Plant samples at various stages (25, 35 and 45 DAS) were analyzed for shoot and root length, number of leaves, flowers, nodules /plant, fresh weight and dry weight of plant. On 65th day yield parameters like number of pods/plant, length of the pod, number of seeds/pod, weight of seeds/pods, pod fresh weight and pod dry weight were analyzed. Result: The experimental results showed that the application T8 (Raw jackfruit peel + 10 g Pleurotus eous + 10 g Pleurotus florida + Eudrilus eugeniae 5 t/ha-1) recorded maximum root (20.63 cm, 32.73 cm and 39.23 cm), shoot length (70.73 cm, 167.50 cm and 175.83 cm), number of leaves/plant (26.46 cm, 33.53 cm and 37.50 cm), number of flowers/plant (12), number of nodules (14, 21.20 and 11.34), fresh weight (10.076 g, 12.146 g and 14.047 g) and dry weight (1.744 g, 1.854 g and 2.827 g) are closely followed by T4 (Raw cocoa shell+ 10 g Pleurotus eous + 10 g Pleurotus florida + Eudrilus eugeniae 5 t/ha-1). A significant increase in the yield parameters such as number of pods/plant (21), length of pod (16.50 cm), number of seeds/pod (20), weight of seed/pod (1.68 g), fresh weight (5.711 g) and dry weight of pod (2.398 g) was observed in treatment T8 as compared to the other treatments (T1, T2, T3, T5, T6 and T7) and control respectively.

Effect of Vermicomposted Vegetable and Fruit Wastes on the Vegetative and Yield Parameters of Lablab [Lablab Purpureus (L.) Sweet]

“…The present results also coincide with the previous findings that integration of NPK (50%) + FYM (50%) +biofertilizers had significant positive impact on yield per plant (1149 g) and total yield (11.05 t ha -1 ) of king chilli Effect of Vermicomposted Vegetable and Fruit Wastes on the Vegetative and Yield Parameters of Lablab [Lablab Purpureus (L.)... (Vimera et al, 2012) and in pigeon pea where an increase in weight of pod, number of pods/plants (243 g and 400 g) were noted when poultry manure was used (Birajdar et al, 2018). Similar results were observed by Silpa and Vijayalakshmi (2021).…”

Efficient Utilization of Agro-industrial Waste through Vermicomposting and its Impact on Growth and Yield of Brinjal (Solanum melongena L.)

“…El-Mohamedy et al (2015) A significant increase in plant height, number of leaves, number of branches, fresh weight and dry weight was observed in bio-compost when compared to the control in potato (Solanum tuberosum L.) plants. The results coincides with Silpa and Vijayalakshmi (2022) who confirmed that the application of biocomposted cocoa shell and jack fruit peel waste increased the shoot length (175.83 cm), The present study was also in agreement where an increase in plant height (32.56 cm) was noted with the application of T 3 -Azolla vermicompost supplemented with 50% NPK, was observed Palia et al (2021).…”

The Effect of Paddy and Coffee Husk as the Organic Manure on the Vegetative and Yield Parameters of Moth Bean [Vigna aconitifolia (Jacq) Marechal]

“…Similar results were observed by Silpa and Vijayalakshmi, (2021) with the inclusion of Jackfruit peel vermicompost resulted in the highest yield of Vigna unguiculata(L) Walp in the treatment 8 such as number of pods (21), length of the pod (16.50 cm), weight of the seeds (1.68 g), pod fresh weight (5.711 g) and dry weight (2.398 g). The results of this particular study also is similar to that of Hasan et al,(2021) with the application of N and P fertilizer on Groundnut plants and found that the plant height (20.65) increased along with the number of pods 74.28% in treatment 15.…”
