Response of paper mill sludge and press mud as soil ameliorants on productivity and nutrient uptake in groundnut (Arachis hypogaea L.) under mid central table land zone of Odisha

Abstract

The field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Mahisapat of Dhenkanal district during kharif season of 2016 and 2017 to study the response of press mud as soil ameliorant on productivity of groundnut under Mid Central Tale Land zone of Odisha. The experiment was laid out in a randomized block design with four replications comprising of six treatments T1-Soil Test Dose (STD), T2-STD+FYM @ 5 t ha-1, T3-STD + PMS 0.2 LR, T4-STD + PMS 0.2 LR + FYM @5 t ha-1, T5-STD+ Press mud 0.2 LR, T6- STD +Press mud 0.2 LR +FYM @)5 t ha-1. It was revealed that T4 recorded significantly higher pod yield (19.45 q ha-1), 100 kernel weight (37.08 g) and shelling percent (67.33) followed by T3 with pod yield (17.58 q ha-1), 100 kernel weight (36.88 g) and shelling percent (67.18). T4 was superior over T1 with the yield advantage of 41.4% and B: C (2.26). The same treatment recorded higher uptake of N, P and K with 111.5, 12.22 and 106.25 kg ha-1, respectively.
