Growth and Yield Parameters of Black Mustard (Brassica nigra L.) under Organic Manures and Different Spacing

Abstract

A field experiment was conducted during Rabi 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. The treatments which are T1: FYM @ 10 t/ha + 20 x 10 cm, T2: FYM @ 10 t/ha + 30 x 10 cm, T3: FYM @ 10 t/ha + 40 x 10 cm, T4: Poultry Manure @ 4 t/ha + 20 x 10 cm, T5: Poultry Manure @ 4 t/ha + 30 x 10 cm, T6: Poultry Manure @ 4 t/ha + 40 x 10 cm, T7: Vermicompost @ 5 t/ha + 20 x 10 cm, T8Vermicompost @ 5 t/ha + 30 x 10 cm, T9: Vermicompost @ 5 t/ha + 40 x 10 cm. The results showed that application of Poultry Manure @ 4 t/ha + 30 x 10 cm recorded significantly higher plant height (134.04 cm), No. of Branches/plant (9.77), Plant dry weight (21.16 g/plant), Crop growth rate (5.16 g/m2/day), Siliqae/plant (174.74), Seeds/siliquae (33.19), Test weight (3.22 g), Seed yield (1749.38 kg/ha), Stover yield (3209.05 kg/ha), gross returns (Rs.96215.90/ha), net return (Rs.65210.90/ha) and benefit cost ratio (2.10) as compared to other treatments.
