Influence of conservation agriculture and organic nutrient management on growth and yield of soybean: French bean cropping system

Abstract

A field experiment on “Influence of conservation agriculture and organic nutrient management on soil health and productivity of soybean – French bean cropping system” was conducted at the All India Coordinated Research Project on Integrated Farming Research System, Mahatma Phule Krishi Vidyapeeth, Rahuri (M.S.) during two consecutive years 2018-19 and 2019-20. The experiment was laid out in split plot design during kharif season and split-split plot design during rabi season with three replications. Among the tillage practices with crop residue management treatments, plant height (cm), no. of branches, leaf area plant-1 (dm2), no. of root nodules plant-1, dry matter production (g plant-1) no. of pods plant-1, no. of seeds pod-1, pod weight plant-1 (g), seed weight plant-1 (g), 100 seed weight (g) seed yield (q ha-1) and straw yield (q ha-1) of soybean and plant height (cm), no. of branches, leaf area plant-1 (dm2), dry matter (g plant-1) no. of green pods plant-1, green pod yield plant-1(g), yield of green pod (q ha-1) and straw yield (q ha-1) of French bean was observed higher in (T1) conventional tillage with crop residue management. In organic nutrient management, plant height (cm), no. of branches, leaf area plant-1 (dm2), no. of root nodules plant-1, dry matter production (g plant-1) no. of pods plant-1, no. of seeds pod-1, pod weight plant-1 (g), seed weight plant-1 (g), 100 seed weight (g) seed yield (q ha-1) and straw yield (q ha-1) of soybean and plant height (cm), no. of branches, leaf area plant-1 (dm2), dry matter (g plant-1) no. of green pods plant-1, green pod yield plant-1(g), yield of green pod (q ha-1) and straw yield (q ha-1) of French bean was observed significantly higher in (F3 and S3) application of FYM @ 7.5 t ha-1.
