Studies on the different amounts of nitrogen and organic sources of nutrient on growth parameters of potato

Abstract

A research study titled “Studies on the different amounts of nitrogen and organic sources of nutrient on growth parameters of potato”. Research Farm, Department of Horticulture, MGCGV, Chitrakoot, Satna (M.P.) during 2016-17 & 2017-18. The details of materials used in experimental they have 20 treatments with control, the experiment analysed (Pooled Basis) under Randomized Block Design (RBD), with three replications. The treatment details are T1- Control, T2- FYM 20 t ha-1, T3- Vermicompost 5 t ha-1, T4- Neem cake 2.5 q ha-1T5- 50 kg N ha-1, T6- 50 kg N ha-1+ FYM 20 t ha-1, T7- 50 kg N ha-1+ Vermicompost 5 t ha-1, T8- 50 kg N ha-1 + Neem cake 2.5 q ha-1, T9- 100 kg N ha-1, T10- 100 kg N ha-1+ FYM 20 t ha-1, T11- 100 kg N ha-1+Vermicompost 5 t ha-1, T12- 100 kg N ha-1+ Neem cake 2.5 q ha-1, T13- 150 kg N ha-1, T14- 150 kg N ha-1+ FYM 20 t ha-1, T15- 150 kg N ha-1+Vermicompost 5 t ha-1, T16- 150 kg N ha-1+ Neem cake 2.5 q ha-1, T17- 200 kg N ha-1, T18- 200 kg N ha-1+ FYM 20 t ha-1, T19- 200 kg N ha-1+Vermicompost 5 t ha-1 and T20- 200 kg N ha-1+ Neem cake 2.5 q ha-1. The observation was recorded under the experiment (growth and yield) of potato such as Plant height (cm), Leaf length plant-1 (cm) and Leaf area plant-1 (cm2). The result revealed that the maximum Plant height (cm) at 30, 60, and 90 DAS (37.39, 58.64 and 61.19 cm) was observed under N4O2 (200 kg N ha-1 + Vermicompost 5 t ha-1), Leaf length plant-1 (cm) at 30, 60, and 90 DAS i.e. (5.33, 8.15 and 8.99 cm) was observed under N4O1 (200 kg N ha-1+ FYM 20 t ha-1), Leaf area plant-1 (cm2) at 30, 60, and 90 DAS was observed under N4O2 (200 kg N ha-1+Vermicompost 5 t ha-1) i.e. (269.42, 532.26 and 612.44 cm2), while the minimum was observed under Control.
