Effect of Boron and Panchagavya on Growth and Yield of Baby Corn (Zea mays L.)

Abstract

The experiment was conducted in the Crop Research Farm, department of agronomy during the summer season of 2022 on baby corn crop. The treatments consisted of 3 levels of boron (2kg, 3kg, 4 kg/ha) and Panchagavya (2 sprays of 2%, 3%, 4%) as a foliar spray at 15 and 30 DAS and a control. The experiment was laid out in Randomized Block Design (RBD) with 10 treatments and replicated thrice. Application of Boron (4 kg/ha) and Panchagavya (2 sprays of 4%) produced maximum plant height (135.44 cm), plant dry weight (138.95 g), number of cobs per plant (3.06), weight of cobs with husk (44.85g), weight of cobs without cob (8.24g), cob yield with husk (7.48 t/ha), cob yield without husk (3.01 t/ha), green fodder yield (41.80 t/ha). Treatment combination with Boron 4 kg/ha and Panchagavya 2 sprays of 4% produced highest gross returns (Rs. 1,44,700/ha), net returns (Rs. 99,845/ha) and benefit cost ratio (2.23) when compared to control (RDF).

Influence of Biofertilizers and Organic Liquid Nutrients on Growth, Yield and Economics of Maize (Zea mays L.)

“…IAA and GA3 present in panchagavya which might have stimulated the production of growth regulators in cell system. Similar results was reported by Sreethu and Singh [13,19]. .…”

“…Similar results was reported by Reddy et al [12] in Finger millet. Further increase in plant dry weight with application of panchagavya 4% might be due to the supply of all micro and macronutrients and growth enzymes present in the panchagavya which favoured rapid cell division and multiplication with respect to Panchagavy-a, ammonia and nitrite oxidizers were found to colonize the leaves and increased the uptake and total N. Simlar results was reported by Sreethu and singh [13].…”

Boron Impact on Maize Growth and Yield: A Review

“…Kumar et al [34] found that treatment B3 (100 ppm) + Si3 (700 ppm) significantly increased plant height. Another study also reported that application of B (4 kg/ha) and Panchagavya (2 sprays of 4%) produced maximum plant height [37]. On the other hand, Dawson found T9 with foliar application of (90 ppm) B (1.5%) recorded higher plant height [43].…”

“…Treatment with B at 4 kg/ha and Panchagavya at 4% produced maximum plant height, plant dry weight, number of cobs per plant, cob yield with and without husk, and green fodder yield [34]. Another study found that foliar application of B at 0.3% resulted in significantly higher growth parameters such as plant height, plant dry weight, and crop growth rate, as well as yield attributes like number of cobs per plant, number of grains per cob, and grain yield [37]. Additionally, the foliar application of B at 0.6% along with zinc and iron increased plant height, plant dry weight, crop growth rate, number of leaves per plant, number of cobs per plant, and grain yieid [38].…”

“…In one study, the treatment with B (4 kg/ha) and Panchagavya (2 sprays of 4%) produced the highest weight of cobs with husk (44.85g) and cob yield with husk (7.48 t/ha) [9]. Another study found that treatment with Misthi variety and 0.3% B foliar application resulted in the highest cob length (18.5 cm) and grain yield (9.5 t/ha) [37]. Additionally, the application of 15 kg zinc with 1.5% B as a foliar spray recorded the highest number of grains per cob (523.93) and grain yield (6.33 t/ha) [9].…”
