3. INTRODUCTION
Mungbean or greengram, Vigna radiata L. is the third important pulse
crop .
Being rich in quality protein ,minerals and vitamins ,they are inseparable
ingredients in the diets of waste majority of Indian population .
when supplemented with cereals ,they provide a perfect mix of essential
amino acid with high biological value .
It is mainly grown in kharif crop in Rajsthan, Maharashtra, Karnataka,
Andra Pradesh, Orissa, Tamil nadu, where as rabi it is grown in
Tamilnadu, Bihar, Orissa, Andhra Pradesh, Uttar Pradesh, West Bengal,
Maharashtra and Karnataka
In summer season it is grown in Uttar Pradesh, Madhya Pradesh, Bihar,
Jharkhand and Maharashtra.

4. INTRODUCTION
 India is large producer of pulses.
 The area under pulses in India is 190 lakh ha.
 In pulses Greengram is majorly grown in India.
 Area under greengram in India is 34.4 lakh ha in the year 2016.
 The production of greengram in India is 14 lakh tonnes and the
productivity is 451.61 kg/ha (Anon., 2016-17).

5. Foliar feeding has been used as a means of supplying supplemental doses of
minor and major nutrients. plant hormones, stimulants and other beneficial
substances observed effects of foliar fertilization have included yield
increases.
 Resistance to diseases and insect pests. improved drought tolerance. and
enhanced crop quality Plant response is dependent on specific fertilizer form.
concentration and frequency of application as well as the stage of plant
growth.
Foliar applications are often timed to conceded With specific vegetative or
fruiting stages of growth. and the fertilizer formula is adjusted accordingly
Applications may also be used to add plants in recovery from transplant shock,
hail damage, or the results of other weather extremes In terms of nutrient
absorption.

15. Conclusion :-
◦Optimum foliar spray of DAP + UREA gave the maximum yield and
quality of the green gram.
◦Among the different foliar spray the 1.5 % DAP + 1.5% UREA gave
the overall superior result e.g. no. of pods, straw yield, grain yield B:C
Ratio etc.
◦ The optimum foliar spray (1.5 % DAP + 1.5% UREA ) is apply at
proper growth stages of crop which helps to increase the economic
crop production of crop.
◦Heavy application of foliar spray increase the production but reduce
the B:C ratio therefore application of foliar spray at recommended
(2%) level is beneficial for crop production.
