Comparative Study of Various Organic Fertilizers Effect on Growth and Yield of Two Economically Important Crops, Potato and Pea

Abstract

In the present experiment, the effect of various house hold wastes i.e. T1 (egg shell powder), T2 (wood ash), T3 (banana peel), T4 (used tea waste), T5 (egg shell tea) and T6 (control) used as organic fertilizers on growth and yield of two important vegetables i.e. potato and pea was investigated. Among all the treatments, the minimum average number of days to germination was observed in T3 in both potato and pea. The overall growth and development of potato and pea plants increased and the average plant height after 30, 60 and 90 days was greater in plants of treatment T1 (egg shell powder). In case of potato, the highest mean plant height (14.75 cm) was observed in treatment T1, followed by T3 and T4 (10.62 cm and 9.87 cm) respectively after 90 days of the emergence. T1 treatment increases the no. of leaves, no. of nodes, no. of branches and leaf area. Regarding tuber yield, the tubers were classified as large (>30 grams), medium (15-30 grams) and small (0.4-15 grams). T1 treatment produced greater average number of large size tubers (2.25) per plant, followed by T3 (1.25); however, the medium and small tubers followed comparable trends with differences among treatments. The average tuber yield (per potato plant) in treatment T1 was higher (113.78 g). In case of pea, T4 treatment (used tea waste) showed the highest mean plant height (82.25 cm). The treatment T1 (eggshell powder), T3 (banana peel) and T4 (used tea waste) showed positive effect on average pod yield (64.82 g, 66.67 g and 114.35 g) respectively. Number of grains per pod and pod size has been found higher in case of treatment T4. It has been concluded that among the different organic treatments, eggshell powder, banana peel and used tea waste were found best as organic fertilizer source for the two vegetables i.e. potato and pea.

Effect of Different Fruit Peel Powders as Natural Fertilizers on Growth of Okra (<em>Abelmoschus esculentus</em> L.)

“…At 6 th and 8 th WAP, the highest leaf area was recorded in T2 (667.17 cm 2 and 741.90 cm 2 respectively) followed by T6 (642.88 cm 2 and 658.08 cm 2 respectively) while the lowest leaf area was recorded in T1 (333.59 cm 2 and 566.40 cm 2 respectively). These findings are agreeable with Mercy et al (2014) who stated that leaf area of the rye plant was higher in fruit peel powder applied soil than control and Wazir et al (2018) noted that application of banana peel as an organic fertilizer into the soil increase leaf area of pea plant. However, there was no variation in leaf area between T2 and T6 at 6 th WAP.…”

“…All four stages, T6 recorded the maximum dry weight of roots and T1 recorded the lowest dry weight of roots (Table 8). Phosphorus promotes rooting, flowering, and fruit set and K is essential for stem and root growth and protein analysis (Wazir et al, 2018). Presence of growth promoting factors and macro and micronutrients in the fruit peel powder may have enhanced the growth of the plants.…”

Fruit Peel Soil Supplementation Induces Physiological and Biochemical Tolerance in Schefflera arboricola L. Grown Under Heat Conditions

“…Singh and Prasad (2014) stated that the improvement in root system development after fruit peel treatments might be owing to the presence of cytokinins in fruit peels. Wazir et al (2018) stated that soil application with banana peel as an organic fertilizer increased the growth rate of pea plants. Foliar application of banana peel extract boosted the shoot and root dry weights of quinoa plants (Bakry et al 2016).…”

Study on Development of Consortia for NPK Bacteria and its Effect on Growth of Selected Crops

“…Mid-season varieties take 75 days to harvest. Late varieties take 100 days to harvest (Wazir et al, 2018). The pods should be harvested in a timely manner and at the highest price point on the market.…”
