Effect of organic nutrient sources on nutrient uptake, yield, and protein content of horse gram (Macrotyloma uniflorum) in upland soil of Jharkhand

A field experiment was conducted in the Western Section of Research Farm of Birsa Agricultural
University, Kanke, Ranchi, during the late kharif season of 2023 to study the evaluation of
different organic nutrient sources on nutrient uptake, yield, and protein content of horse gram
(Macrotyloma uniflorum) in upland soil of Jharkhand. The experiment was laid out in a
Randomized Block Design (RBD) with three replications, and the variety used was Birsa Kulthi-1.
The treatment consists of100% N through FYM (T 1 ),100% N through Vermicompost (T 2 ),100% N
through Karanj Cake (T 3 ), 50% N through FYM+50% N through VC (T 4 ),50% N through
FYM+50% N through KC(T 5 ),50% N through KC+50% N through VC (T 6 ), 1/3 N through
FYM+1/3 N through VC+1/3 N through KC(T 7 ), 50% N through FYM (T 8 ), 50%N through VC
(T 9 ), 50% N through KC (T 10 ) and Control (T 11 ). Application of 50% N through FYM+50% N
through VC (T 4 ) resulted in the highest seed yield (770.53 kg/ha), stover yield (1781.40kg/ha), and
harvest index (30.18%). Protein content was non-significant; however, numerically higher protein
content (24.23%) was obtained with 50% N through FYM + 50% N through VC (T4), which also
resulted in a significantly higher protein yield (186.94 kg/ha).The nitrogen uptake in seed (29.95
kg/ha), nitrogen uptake in stover (24.94 kg/ha), total nitrogen uptake (54.89 kg/ha), phosphorus
uptake in seed (2.82 kg/ha), phosphorus uptake in stover (4.10 kg/ha), total phosphorus uptake
(7.28 kg/ha), potassium uptake in seed (4.21 kg/ha), potassium uptake by stover (23.19 kg/ha) and
total potassium uptake (27.40 kg/ha) respectively was higher with application of T 4 (50% N
through FYM+50% N through VC).
