Effect of different levels of organic manure on the growth and yield of mustard (Brassica juncea L.). under Jatropha (Jatropha circus L) based agroforestry system

Abstract

A field experiment was conducted during Rabi season of 2017-18 at Research farm, College of Forestry, SHUATS, Allahabad. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH6.7), low in organic carbon (0.35%), N (230kg/ha), P(20kg/ha) and K(98kg/ha), The treatment comprised of 3 levels of FYM,VC and PM viz.T1 (control),T2 (100% FYM), T3(100%PM), T4(100%VC), T5(50%FYM+50%VC), T6(50%FYM+50%PM), T7(50%FYM+25%VC+25%PM), T8(25%FYM+25%VC+50%PM), T9(25%FYM+25%PM+50%VC). There were 9 treatments; each replication thrice, the experiment was laid out in RBD. The result was shows that maximum plant height was recorded (169.27 cm)at 80DAS, number of branches (5.26)at 80 DAS, dry Weight (76.03 g) at 80DAS and yield attributes viz., number of Siliqua plant-1(5.85) at harvesting time, number of seeds Siliqua- (13.46) at harvesting time, Test weight (4.93g) after harvest, Seed yield (1.49 t/ha-1) after harvest, after harvest, Stalk yield (1.93 t/ha-1), B:C.Ratio 1:4.3, were recorded in treatment (T5 50% FYM+50%VC). These parameters were significantly influenced by different sources and doses of organic manure.
