SYNOPSIS SEMINAR

2.  According to the data from Central ground water board,the state
average decline in the water table is about 10.65m from 1974 to
2019.
 Of the total 1.1 crore acres of geographical area in the Haryana 9.8
lakh acres (8.8%) is affected with the twin problem of water logging
and salinity (Reference: CSSRI).
 The irrigation water sources is one of the most important factors,
which may directly affect the plant growth and productivity of
plants.
 Crop required large amount of irrigation water, with increasing
water scarcity, the use of saline water is one of the suggested
alternatives for irrigation purpose.

INTRODUCTION

3.  About 62% area of the Haryana is covered with poor quality water.
To overcome this situation, efficient use of poor quality water such
as saline water is becoming more important.
 The yield of vegetables decreases with the increase in salinity.
Therefore, agricultural production alternatives must be sought to
meet the demand for food, mitigating the harmful effects of
salinity.
 Soil salinity became a major constraint to vegetable crop
production, the use of FYM, biofertilizers and plant growth
regulator can mitigate salinity effects on vegetables and reduce soil
salinization.

4.  To study the effect of integrated nutrient management on
soil properties under saline water irrigation
 To study the effect of integrated nutrient management on
growth and yield of brinjal crop under saline water
irrigation

Objectives

5. Saline water irrigation levels:
I1 = Control (Canal water)
I2= ECiw (2.5 dS/m)
I3 =ECiw(5.0 dS/m)
Nutrient management:
T1= Control
T2= Recommended dose of fertilizer(RDF) (N:P:K=100:50:25 kg/ha)
T3= 125%RDF (N:P:K=125:62.5:32 kg/ha)
T4=75%RDF + FYM(@25t/ha) + Azotobacter chroococcum (MAC 27) + PSB 36
T5= 75% RDF + FYM(@25t/ha) + Salicylic acid(@250ppm) at vegetative and 50% flower initiation stage
T6= 75%RDF + FYM(@25t/ha) + Azotobacter chroococcum (MAC 27) + PSB 36 + Salicylic acid (@250ppm) at vegetative
and 50% flower initiation stage
