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).
