Abstract
An experiment was conducted at Biratnagar, Nepal in completely randomized block design to study the effect of effective microorganisms (EM) and indeginous microorganisms (IMO) along with recommended dose of fertilizers (RDF) on the growth and yield parameters of okra (variety: Arka Anamika). The 6 treatments viz. control, EM enriched manure, IMO enriched manure, RDF, RDF+EM, RDF+IMO and control were replicated thrice. The study showed that indeginous microorganisms when incorporated with recommended dose of NPK fertilizer (RDF+IMO) can produce best result in terms of yield and economic return. Rigorous study in multi location and more crops is suggested to develop an integrated nutrient management plan and household waste management.

Soil fertility degradation, caused by erosion and depletion or imbalance of organic matter/nutrients, is affecting world agricultural productivity
The experiment on impact of biochar and vermicompost on sweet orange plant was started at Regional Agricultural Research Station (RARS), Jamalpur during 2017-2018
The experiment was conducted to determine the impact of biochar and vermicompost for quality sweet orange production during the fruiting season of 2017-18
Summary
Soil fertility degradation, caused by erosion and depletion or imbalance of organic matter/nutrients, is affecting world agricultural productivity. Inorganic fertilizers have played a significant role in increasing crop production since the “green revolution”; they are not a sustainable solution for maintenance of crop yields. Organic amendments, such as compost and biochar, could be useful tools to sustainably maintain or increase soil organic matter, preserving and improving soil fertility and crop yield. Some recent studies have indicated that combined applications of biochar with organic or inorganic fertilizers could lead to enhanced soil physical, chemical, and biological properties, as well as plant growth. It has a scope to ensure the yield and quality of BARI Malta-1 checking the deficiency of nutrients Under such situation, integrated plant nutrient system (IPNS) has assumed a great importance and has vital significance for the maintenance of soil productivity. With the above point of view, the present study was carried out to determine the effect of biochar application alone or combined with vermicompost on (i) plant growth and yield ii) physical, chemical and biological properties of soil
