Effect of seed priming with botanicals on plant growth and seed yield of lentil (Lens culinaris M.)

Resumo

Um experimento de campo foi conduzido durante a temporada de rabi, 2018-19 na Fazenda de Pesquisa, Departamento de Ciência e Tecnologia de Sementes, Chauras Campus, H. N. B. Garhwal University, Srinagar (Garhwal), Uttarakhand, Índia para estudar o efeito do condicionamento de sementes com fitoterápicos no crescimento e produção de sementes de lentilha (Lens culinaris M.). O experimento foi colocado em Design de Blocos Randomizados e replicado três vezes. O experimento de campo consistiu em seis tratamentos, a saber, condicionamento das sementes com folhas de nim extrato (50%), óleo de rícino (20%), extrato de gengibre (50%), extrato de cebola (50%) e alho extrato (50%) e controle. O condicionamento de sementes com 50% de extrato de alho inibe germinação devido à presença de alicina. A porcentagem máxima de germinação (90, 80%), número de ramos por planta (5,20), sementes por vagem (1,87), 1000 sementes peso (20,24 g), rendimento por planta (3,51 g) e rendimento por ha (9,94 g) foram observados quando as sementes foram condicionadas com extratos de folhas de nim (50%). Considerando que, planta máxima altura aos 60 DAS (12,80 cm) e número de vagens por planta (174,73) foram observados quando as sementes foram condicionadas com extrato de cebola (50%).



Abstract

A field experiment was conducted during rabi season, 2018-19 at the Research Farm, Department of Seed Science and Technology, Chauras Campus, H. N. B. Garhwal University, Srinagar (Garhwal), Uttarakhand, India to study the effect of seed priming with botanicals on plant growth and seed yield of lentil (Lens culinaris M.). The experiment was laid out into Randomized Block Design and replicated three times. The field experiment consisted of six treatments viz., seed priming with neem leaf extract (50%), castor oil (20%), ginger extract (50%), onion extract (50%) and garlic extract (50%) and control. The seed priming with 50% extract of garlic inhibits germination due to the presence of Allicin. The maximum germination percentage (90.80%), number of branches per plant (5.20), seeds per pod (1.87), 1000 seeds weight (20.24 g), yield per plant (3.51 g) and yield per ha (9.94 g) were observed when seeds were primed with neem leaf extracts (50%). Whereas, maximum plant height at 60 DAS (12.80 cm) and number of pods per plant (174.73) were observed when seeds were primed with onion extract (50%).
