The present investigation entitled “Effect of integrated nutrient management on late sown mustard under punjab conditions (Brassica campestris L.)” was conducted during rabi season of 2018-19 with the objective to find out the impact of integrated nutrient management on growth, yield, nutrient content, nutrient uptake and economics of Mustard. The soil of experimental field was clay loam texture, alkaline in nature with pH (7.91), EC is (0.59) and available nitrogen (205.5) kg ha-1, available phosphors (12.7 kg ha-1), available potassium (231.5 kg ha-1), available sulphur (7.50 kg ha-1), available zinc (0.94) and boron (0.72 mg kg-1).
The experimental results revealed that significantly maximum growth parameters (plant height, branches plant-1, dry matter accumulation, and leaf area index), yield attributes (siliqua length, siliquae plant-1, seeds siliqua-1and test weight), yield (grain and stover), nutrient uptake(N, P, K, S, Zn and B) by grain and stover and available soil nutrient (N, P, K, S, Zn, and B), were noticed under the application of 100% NPK+40 kg S+1.5 B+20 kg Zn ha-1 as compared to rest of the treatments.
The increment in seed yield under application of 100% NPK+40 kg S+1.5 B+20 kg Zn ha-1 was 25.32 % over 100% NPK. Likewise, maximum gross return, net return and B:C ratio were also recorded with the application of 100% NPK+40 kg S+1.5 B+20 kg Zn ha-1. Besides, this combination also improves the quality of produce and physico-chemical properties of soil. The results revealed that among nutrient management practices, the application of 75% RDF + FYM 10t ha-1 being at par with 75% RDF + vermicompost 5t ha-1 recorded maximum growth and yield attributes, grain (24.14 and 21.74 q ha-1, respectively), strover (81.75 and 75.24 q ha-1, respectively) & biological yield (104.82 and 99.44 q ha-1, respectively), nutrient content and NPK uptake of mustard. In contrast, the application 75% RDF + FYM 10t ha-1 exhibited maximum net return (43228.5 ₹ ha-1) and B: C (1.05) of mustard.

Research Objectives and Focus
The primary aim of this study is to evaluate the influence of Integrated Nutrient Management (INM) practices on the productivity, growth parameters, and yield attributes of late-sown mustard (Brassica campestris L.) in the Punjab region. By conducting field experiments during the Rabi season, the study seeks to determine the optimal nutrient combinations that can enhance crop performance, improve soil fertility, and ensure economic viability for farmers facing the challenges of late sowing.
- Assessment of various INM treatments on mustard growth and yield attributes.
- Evaluation of nutrient content and uptake efficiency in mustard plants.
- Analysis of the economic feasibility and cost-benefit ratios of different nutrient management strategies.
- Investigation into the impact of INM on soil physico-chemical properties.
- Identification of the most effective nutrient combinations to mitigate the negative impacts of late-sown conditions.

Frequently Asked Questions
What is the core focus of this research?
The research focuses on the impact of Integrated Nutrient Management (INM) on the yield and growth of late-sown mustard crops under Punjab conditions.
What are the primary themes investigated in this work?
The primary themes include the effects of various nutrient combinations, the assessment of crop growth and yield attributes, the analysis of nutrient uptake, and the economic performance of different treatments.
What is the main objective of this study?
The main objective is to identify optimal nutrient management practices that increase mustard productivity despite late sowing and to evaluate the economic feasibility of these treatments for farmers.
What scientific methodology was employed?
The researchers used a field experiment approach with a randomized block design (RBD) involving 12 different nutrient management treatments across three replications.
What does the main body of the work cover?
The main body covers a comprehensive review of literature, detailed descriptions of the materials and methods (including fertilizer application and field design), analysis of growth and yield results, and a discussion of these results regarding economic and soil property outcomes.
What keywords best represent the work?
Key terms include Integrated Nutrient Management, mustard (Brassica campestris), yield attributes, nutrient uptake, late sowing, and economic feasibility.
How does late sowing affect mustard production according to the text?
Late sowing typically leads to decreased productivity due to the shortening of the vegetative and reproductive phases, as well as exposure to higher temperatures, which causes forced maturity and lower crop yield.
Why is Integrated Nutrient Management (INM) important for this study?
INM is crucial because it combines the use of organic manures and inorganic fertilizers, which together provide balanced nutrients, enhance soil health, and mitigate the yield losses associated with sub-optimal environmental conditions like late sowing.
