Abstract
Onion is one of the most important vegetable crops grown in India, having both the
food and medicinal values. Due to its ability to flavour a variety of vegetable preparations, it is
a necessary component of every kitchen and is referred to as the "Queen of the Kitchen". The
experiment was conducted in a randomized block design with three replications at Vegetable
Research Farm of BUAT, Banda, during the Kharif season of 2022. The holistic aim of this
experiment was to search out the most suitable variety of Kharif onion that could easily
produce the optimum yield with better profitability and also to standardize appropriate organic
and inorganic nutrient management techniques that suit well to the crops and variety in the
region. The experiment consisted of one-factor treatments. Therefore, a total of 09 treatments
combination arrived to test, and every treatments were replicated thrice in an experimental unit
i.e., T1- Farmer practice (NPKS): 70-40-40-0 kg/ha, T2- NPKS:100- 50-50-30 kg/ha, T3- NPKS:
120-50-50-40 kg/ha, T4- NPKS: 140-50-60-50 kg/ha, T5- NPKS: 150-50-60-70 kg/ha, T6- 20
tons enriched FYM, T7- 75% RDN + 5 tons enriched FYM, T8- 50 % RDN + 10 tons enriched
FYM, T9- 25 % RDN + 15 tons enriched FYM and they were applied with an objective to study
the effect of organic and inorganic nutrients on growth, yield, quality and economics of kharif
onion.
In general, the weather condition was quite conducive resulting in harnessing good
crop yields during the year of field experimentation. The soil of the experimental field was silt
clay loam in texture having moderate basicity (pH-8.2, EC-0.31) and poor fertility. Overall, the
soil holds organic carbon of 0.38 %, available nitrogen of 254 kgha-1
, available phosphorus of
17.3 kgha-1
, potassium of 259.3 kg ha-1
and Sulphur of 13.96, respectively.
On the basis of result obtained and summarized from the present study, it can be
concluded that all the observations taken for kharif onion were found to be superior with the
application of organic and inorganic nutrients. In the study, it was observed that the application
of T9-25 % RDN + 15 tons enriched FYM increased all growth and yield parameters such as
plant height (cm), number leaves (cm), neck thickness (cm), bolting percentage, days to
maturity (60-70%) neck fall followed by T7- 75% RDN + 15 tons enriched FYM and T8- 50%
RDN + 10 tons enriched FYM. While the maximum B: C was recorded under T5-NPKS: 150-
50-60-70 kg/ha followed by T5- NPKS: 150-50-50-30 kg/ha, T4- NPKS: 140-50-60-50 kg/ha
and T8-50% RDN + 10 tons enriched FYM. There for among all the combinations of organic
and inorganic nutrients applied 25 % RDN + 15 tons enriched FYM was found significantly
most effective in increasing the yield and yield attributing traits.
Hence, application of T9-25 % RDN + 15 tons enriched FYM recorded higher yield
(232.22 q/ha) and excellent quality bulbs may be suggested for cultivation in kharif onion as
well as the maximum net return per hectare but maximum B: C ratio observed in Treatment T5-
NPKS: 150-50-50-30 kg/ha due to low cost of cultivation. However, we can see the soil status
in treatment T9-25 % RDN + 15 tons enriched FYM, that is significantly improve the soil
health and fertility under Bundelkhand region.
