Abstract:
A field experiment was conducted during consecutive two years of 2019-20 & 2020-21 entitled “Effect of nutrient management and moisture conservation practice on roots and yield attributes of Pearl millet (Pennisetum glaucum L.) Under light textured soil.” at Soil Conservation and Water Management Farm of Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The experiment was comprised total eighteen treatment combination of six nutrient management viz. N₁) Control, N₂) 100% NPK 80:40:40 kg ha^-1 through RDF, N₃) Green manuring + 75% NPK through RDF, N₄) Green manuring + FYM 10 t ha^-1, N₅) FYM @ 10 t ha-¹ + 75% NPK through RDF and N₆) FYM@ 10 t ha^-1 + 50% NPK through RDF) and three moisture conservation practices viz. M₁) Control, M₂) inter-row water harvesting and M₃) Ridge making at 25 DAS. The conducted field experiment was framed in Factorial Randomized Block Design with three replication. The results of conducted field experiment revealed that treatment N₅ (FYM @ 10 t ha-¹ + 75% NPK through RDF) among the nutrient management and treatment M₃ (Ridge making at 25 DAS) among the moisture conservation practices were found significantly superior and recorded significantly maximum root and yield attribute parameters. The treatment N₅ treated with FYM @ 10 t ha-¹ + 75% NPK through RDF was recorded significantly maximum length of ear (21.45, 21.6 cm), No. of grains ear^-1 (1623.9, 1627.5), no. of ears (4.86, 4.97), grain weight plant^-1 (14.58, 14.88) and test weight (8.98, 9.02 g) and root parameters viz. depth of roots (17.2, 19.8 cm) and number of roots (59.8, 61.6) and similarly treatment M₃ of moisture conservation practices (Ridge making at 25 DAS) was also recorded significantly maximum length of ear (19.67, 19.81 cm), no. of grains ear^-1 (1565.2, 1569.8), no. of ears (4.45, 4.55), grain weight plant^-1 (13.44, 13.5) and test weight (8.57, 8.65 g) and root parameters viz. depth of roots (16.8, 19.0 cm) and number of roots (58.1, 60.3) than rest of treatments in experimental crop during the both years of experimental studies.
