Effect of different levels of N P K and Zn on physico-chemical properties of soil growth parameters and yield by pea (Pisum sativum L.) Cv. Rachana

Abstract

A study was conducted on the “Effect of N P K and Zn on Physico-chemical Properties of Soil, Growth Parameters and Yield by Pea (Pisum sativum L.) Cv. Rachna”, at the Soil Science Research Farm, Sam Higginbottom University of Agriculture & Technology Sciences. Allahabad during Rabi season 2017-2018. The number of pods plant-1 (19.53), number of seeds pod-1 (6.20) and pod yield (77.67qha-1) were significantly increased with the application of 50% recommended dose of N P K fertilizers and 100% Zinc fertilizer. The maximum yield was obtained in T5 – [N@ 20kg + P@ 40kg + K@ 20kg and Zn@ 20kg ha-1]. Growth parameters, soil properties, increased significantly with the application of 100% recommended dose of fertilizers i.e. T8 – [N@ 40kg + P@ 80kg + K@ 40kg and Zn@ 20kg ha-1], pH, EC (dSm-1) and bulk density (gcm-3) were they decreased with increase in fertilizer levels. The lowest values related to all parameters were obtained in control treatment. Cost benefit ratio (C:B) 1: 2.29 was highest in T5 - (i.e. N@ 20kg + P@ 40kg + K@ 20kg and Zn@ 20kg ha-1) 50% recommended dose of NPK and 100% Zinc was more profitable Rs. 59234.00 than any other treatments and recommendations.
