ABSTRACT: There is a direct need to increase crop productivity per unit area and per unit time. Cotton with the

relatively longer life cycle (150-175 days), wider space and its skimpy initial growth keeps the inter row space

remain as vacant from sowing to 60-75 days. It gives ample scope for raising short duration pulse, cereal and

vegetable as intercrops. The experiment was conducted during kharif season of 2016 at Cotton Research Area of

CCS Haryana Agricultural University, Hisar. Treaments with different intercropping systems were desi cotton +

Pearlmillet (1:1), Desi cotton + Pearlmillet (1:2), Desi cotton + Greengram (1:1), Desi cotton + Greengram (1:2), Bt.

Cotton + Pearlmillet (1:1), Bt. cotton + Pearlmillet (1:2), Bt. Cotton +Greengram (1:1), Bt. Cotton +Greengram (1:2),

sole Desi cotton and sole Bt. cotton. Laid out in randomised block design (RBD) with three replications. Higher

number of sympodial branches, boll weight, number of bolls and seed cotton yield was observed with Bt. Cotton +

Greengram (1:2). Highest land equivalent ratio (1.70) and crop equivalent yield (5028 kg/ha) was also recorded in

Bt. Cotton + Greengram (1:2).

Cotton popularly known as “King of fiber

“and “White Gold” is a major fiber crop of the

world and is used by about 75 per cent of world’s

population for textile purposes. Its fiber is used

universally as a textile raw material. In India, it is

an important cash and commercial crop valued

for its fiber and vegetable oil and also a source for

earning the valuable foreign exchange by providing

employment to millions of people, hence plays

significant role in national economy. The diverse

products obtained from cotton include textile raw

material, cotton seed is a major source of

vegetable oil and cotton cake as a rich source of

high quality protein for livestock feed.

Current agriculture is facing a situation

with formidable problems of stagnating production

due to decline in factor productivity, degrading

soil health, inefficiency of current production

practices, scarcity of resources, and high cost of

cultivation and low returns to the farmers as ill

effects of green revolution which concentrates on

maximum output but overlooks input efficiency.

The only way to increase crop productivity on per

unit area basis is possible through intercropping.

Thus to meet out the challenges imposed by

over use of natural resources and to sustain

productivity level improved crop management

through inclusion of legume crops in crop

rotations and intercropping of legumes with

cereals have many potential benefits as compared

to sole cropping systems (Venkateswarlu and

Sarkar, 2009).

Intercropping is an age old practice in

India, especially under rainfed conditions, which

aims to increase total productivity per unit area

and to equitably and judiciously utilize land

resources and farming inputs including labour.

Development of feasible and economically viable

intercropping systems largely depends on

selection of compatible crops and adoption of

proper planting geometry. Although research is

still ongoing, there is strong evidence that

intercropping can substantially increase the

yield from a given area of land. As well, intercrops

may require lower levels of costly inputs through

increased resource-use efficiency. Besides

supplementing to productivity per unit area and

time, these intercrops serve as an insurance

Cotton as a crop as well as a commodity

plays an important role in the agrarian and

industrial activities of the nation and has a unique

place in the economy of our country. Cotton,

popularly known as “White Gold” is cultivated

mainly for fibre and additionally as an important

source of edible oil. India devotes more area to cotton

than any other country in the world. At present,

India ranks first in area with11.88 M ha, accounting

30 per cent of world average and 22 per cent (351

lakh bales of lint) of the world cotton production with

a lint productivity of 568 kg/ha (Anonymous, 2017).

Nearly 65 per cent of the cotton crop is cultivated

under rainfed condition in the country. In Tamil

Nadu, 1.33 lakh ha area is under cotton cultivation

with a production of 6.5 lakh bales with and lint

productivity of 620 kg/ha. India has been the

traditional home of cotton and their textiles. India has

progressed substantially in improving both

production and productivity of cotton over the last five

against menace of pest and disease and vagaries

of weather to which monocroped cotton is usually

subjected to. The introduction of leguminous

intercrops in cotton will helps to maintain the soil

fertility level.

In cotton growing region, cotton based

intercropping system are popular because the

short duration intercrop will help farmer to

realize the income needed interimly to meet the

domestic food and fodder requirement. The short

duration compact crops like green gram, black

gram, pearlmillet, onion and other vegetables

when grown as intercrop in cotton has little or no

adverse effect on the growth and development of

cotton (Satish et al., 2012 and Khan et al., 2001).

For getting higher return per unit land

area intercropping appears to be one of the

important aspect. Taking into consideration the

above facts it has become imperative to find out

the suitable crops and optimum row ratio for

higher productivity. Therefore, the experiment

entitled “Performance of Cotton genotypes

intercropped with Pearl millet and Greengram.”

was planned for execution during kharif season

of 2016 at Cotton Research Area of CCS Haryana

Agricultural University, Hisar.

The seed bed was prepared after pre sowing

irrigation at field capacity. Two harrowing

followed by ploughing with cultivator after that

planking was done as preparatory tillage for the

entire plot. The main crop of cotton was sown by

dibbling method after layout at a spacing of 67.5

x 30.0 cm for desi cotton and 67.5 x 60.0 cm for

Bt. cotton. Both intercrops greengram (MH-421)

and pearlmillet (HBB 67 i) was sown by hand

plough with 1:1 and 1:2 row ratios, respectively.

The five tagged plant of cotton from each

plot were selected for counting number of monopods

and sympods at final picking. Average number of

monopods and sympods were used for statistical

analysis. The seed cotton obtained from five

tagged plants was weighed and divided with

number of bolls picked to get average boll weight.

A composite seed sample was drawn from the

individual plot seed cotton yield and 100 seeds of

cotton were counted and their weight was taken.

The weight was taken in gram (g).

Two pickings were done and the seed

cotton of each picking from each plot was

weighed separately. The total of both the pickings

together with yield of five tagged plants was taken -1as seed cotton yield plot and was calculated

-1hectare basis.

Land equivalent ratio (LER) : Land

equivalent ratio of the different intercropping

systems was calculated by the following formula

given by Willey (1979).

LER =

Y = Individual crop yield under intercropping i

system

Y = Individual crop yield under sole cropping ij

system

Crop equivalent yield : Yield of different

intercrops are converted into equivalent yield of

any one crop based on price of the produce. It is

calculated by the following formula :

CEY = (Y xe )i i

thWhere, Y = yield of i componenti

th e = equivalent factor of i component or i

thprice of i crop.

The experiment was conducted in RBD

design along with three replications. All the tests

of significance were made at 5 per cent level of

significance.

RESULTS AND DISCUSSION

The monopodial and sympodials branches -1plant were higher under sole Bt. cotton (3.66

and 22.20) as compared to sole desi cotton. But

with greengram intercropping these values were

3.7 (1:1) and 22.6 with (1:2) indicating a increase

monopodial and sympodials branches/plant

respectively (Table 1). Previous literature showed

contrasting results. Investigation of Sheoran and

Malik (1986) that the monopolial branches were

un affected by intercropping greengram, whereas

Rao (1982) confirmed present investigation that

the monopolial and sympodial branches were

signi f icantly reduced by intercropping

greengram. These variable responses in different

investigations could probably be partly due to the

magnitude of competition in the intercropping

system grown in variable geometry and varieties

of crops with varying competitive ability. The

decrease in number of sympodial branches had a

definite impact on the productions of seed cotton

yield because they are the main fruit bearing

branches and are more in number compared to

monopodials. The results of Deoche et al., (2004)

also corroborated with the present findings.

The bolls/plant and boll weight were

maximum under Bt cotton with greengram (1:2)

(Table 1). Bt cotton with greengram produced

maximum bolls/plant (45) and with pearlmillet

the boll number reduced upto 29.0. Bt cotton

intercropped with greengram (1:2) produced

more bolls weight (4.9 g) than sole crop (4.6 g). Bt

cotton intercropped with greengram (1:2)

produced maximum seed cotton yield of 4663

kg/ha. More bolls/plant coupled with increased

boll weight was the reason for maximum seed

cotton yield kg/ha under intercropped crop of

cotton. This might be due to less competition in

greengram due to short duration crop.

Greengram as intercrop shows synergistic effect

on Bt. cotton yield by fixing atmospheric nitrogen

and providing better nutrition to the cotton plant.

There was definite increase in these parameters

by intercropping cotton with greengram. Increase

in seed cotton yield due to intercropping of

greengram was earlier reported by several research

workers (Prasad et al., 1993, Wankhade, 1994,

Ramesh Babu et al., 1996, Sanjay et al., 2003,

Doeche et al., 2004, SreeRekha et al., 2008, Reddy

and Mohemmad, 2009 and Satish et al., 2012).

Intercrop, greengram shared resources with cotton

and offered a stiff competition thereby hindering

the optimum growth and development of

monopodial, sympodial branches and thereby

number of bolls and reduced the recovery of seed

cotton yield/plant and ultimately seed cotton -1yield hectare .

Cotton intercropped with pearlmillet give

significantly lower seed cotton yield as compared

to sole cotton or cotton intercropped with greengram.

Similar results were observed by Singh and

Singh (2015).

Bt cotton intercropped with greengram

(1:2) had higher land equivalent ratio as

compared to all other treatments (Table 2).

Similar results also found by Singh et al., (2014).

Crop equivalent yield was also highest when Bt

cotton was intercropped with green gram (1:2)

followed by Bt cotton intercropped with green

gram (1:1). Desi cotton intercropped with

ABSTRACT: The present investigation was carried out at Cotton Research Area of CCS Haryana Agricultural

University, Hisar, during kharif season of 2018 to study the effect of application method and scheduling of

nitrogen on yield attributes, yield, economics and nitrogen use efficiency in Bt cotton. The result revealed that with

spot application of 75 per cent recommended nitrogen in four splits (sowing, squaring, flowering and boll development)

along with incorporation of two rows of moong at 50-55 days after sowing gave the higher number of bolls/m

(135), boll weight (4.2 g) and highest seed cotton yield (5259 kg/ha). Also nitrogen use efficiency (18.38 %), net

return (Rs. 145519/ha) and benefit cost ratio (2.05) was found highest with this treatment but all these

parameters are statistically at par with application of 100 per cent recommended dose of nitrogen (175 kg/ha) in

two splits, Although there was no significant difference found among various treatments for monopodial

branches/plant, sympodial branches/plant and seed index.

Key words: Cotton, economics, nitrogen scheduling, nitrogen use efficiency

Effect of methods of application and scheduling in nitrogen on

nitrogen use efficiency and seed cotton yield of Bt cotton in semi

arid regions of Haryana

Cotton is an international crop grown by

about 80 countries across the world over an area

of 32.95 m ha. India with first rank contributes

about 33.23 per cent of cotton at world level. The

area, production and productivity of cotton in

India is 12.2 m ha, 37.7 m bales, 524 kg/ha,

respectively (Anonymous, 2018). Cotton is an

important cash crop of kharif season in Haryana

state which plays an important role in state’s

economy through employment and export

earnings. The four major cotton growing districts

of Haryana viz; Sirsa, Hisar, Jind and Fatehabad

form the cotton belt of the state. The major area

about 90 % or around 5.90 lakh ha is under

American cotton Gossypium hirusutum whereas

desi cotton (G. arbarium) comprises 0.91 per cent

(around 6000 ha). Area under Bt cotton,

increased in Haryana from year 2016 (4.98 lakh

ha) to 2017 (6.56 lakh ha) (Anonymous, 2018).

Bt cotton hybrids and their scope for

extensive coverage in the country in coming

years, necessitated for change in the nutrient

management of Bt cotton hybrids. The agronomic

factors responsible for low yield of cotton in the

country are numerous among which inappropriate

fertilizer management is considered major one.

Nitrogen is the most limiting essential plant

nutrient in the world and it needs to be supplied

in appropriate amount and at right time.

Nitrogen is considered to be the most important

nutrient for increasing the cotton yield. Nitrogen

is an important element for photosynthesis and

canopy area development. Providing the right

amount of N during the plant growth will provide

healthy leaves with the photosynthetic capacity

needed to support the development of the

reproductive components. On other hand an

inadequate supply of N will slow or stop leaf

development. Surplus N application encourages

excessive vegetative growth, resulting in poor boll

set caused by vegetative shading and insect

attractiveness, late maturity and difficulty in

defoliation. Insufficient dose of nitrogen and its

application at improper time result in slow

growth of boll development and provide more

favourable environment for growth of insects
