The present study focus on Effect of N-management practices and different organic sources on growth and yield of kharif sesame (Sesamum indicum L.). The treatment combinations comprised consisting of application of nitrogen viz., N0 (Control), N1 (25 kg N ha-1), N2 (Azospirillum) and N3 (50 % RDN + Azospirillum) relegated to main treatment and other sub treatments comprised of application of organic manure viz., M1 (Humic acid 10 kg ha-1), M2 (Poultry Manure 500 kg ha-1) and M3 (Vermicompost 500 kg ha-1). The results revealed that treatment N3 (50 % RDN + Azospirillum) recorded significantly higher. While, treatment N2 (Azospirillum) significantly the highest harvest index. Treatment N3 (50 % RDN + Azospirillum) recorded significantly higher seed yield (479 kg ha-1) and stover yield (1960 kg ha-1) of sesame. Application of humic acid 10 kg ha-1 (M1) secured higher seed yield (444 kg ha-1) and stover yield (1716 kg ha-1).The interaction effect of nitrogen and organic manure application revealed that treatment combination N2M3 (Azospirillum along with vermicompost 500 kg ha-1) recorded significantly the highest harvest index (39.20 %), but treatment combination N3M1 (50 % RDN + Azospirillum along with humic acid 10 kg ha-1) recorded significantly the highest seed yield (580 kg ha-1).

Research Objective and Scope
This thesis examines the impact of various nitrogen management practices and organic soil amendments on the growth performance and yield components of kharif sesame (Sesamum indicum L.) under the specific agro-climatic conditions of the Middle Gujarat region. The research aims to identify optimized, sustainable nutrient management techniques that reduce reliance on chemical fertilizers while maximizing crop profitability for local farmers.
- Investigation of different nitrogen application levels and bio-fertilizer usage.
- Evaluation of organic manure sources including Humic acid, Poultry manure, and Vermicompost.
- Analysis of growth attributes such as plant height and branching patterns.
- Assessment of yield parameters, including capsule count, harvest index, and final seed/stover yield.
- Economic evaluation through Cost-Benefit Ratio (CBR) calculation to ensure practical agricultural viability.

Frequently Asked Questions
What is the primary focus of this research?
The research focuses on determining the best nitrogen management practices and organic sources for improving the growth and yield of kharif sesame in Middle Gujarat.
Which organic sources were tested in this experiment?
The experiment evaluated Humic acid (10 kg ha-1), Poultry manure (500 kg ha-1), and Vermicompost (500 kg ha-1).
What is the main goal of the study?
The goal is to provide farmers with evidence-based strategies for achieving higher seed yields and net realization using balanced organic and inorganic nutrient sources.
What methodology was adopted?
A field experiment was conducted using a Factorial Randomized Design with twelve treatment combinations replicated four times.
What does the main body of the work cover?
It covers weather influences, nitrogen effects on growth and yield, organic manure impacts, and a comprehensive economic analysis of the treatment results.
Which criteria are used to characterize the study?
The study is characterized by keywords such as nitrogen management, organic amendments (Humic acid, Poultry manure, Vermicompost), yield attributes, and economic viability.
What specific interaction effect resulted in the highest seed yield?
The treatment combination N3M1 (50% RDN + Azospirillum along with Humic acid 10 kg ha-1) recorded the highest seed yield of 580 kg ha-1.
Why is Nitrogen considered a crucial element in this study?
Nitrogen is essential for promoting vegetative growth and synthesizing chlorophyll, which directly influences the plant's yield potential, despite its increasing cost.
What is the practical recommendation of the author?
The author recommends the application of 50% recommended nitrogen combined with Azospirillum and 10 kg ha-1 of Humic acid to achieve remunerative yields.
