Impact of the varieties/technologies developed under AICRP on Sugarcane
The relative contribution of an improved variety and production technology dwell around 70: 30 under normal conditions. Here, the impact of leading variety/proven technology is given to give a glimpse of the total impact over the years at the national level.
1- Impact of the varietal development
Sugarcane varieties developed under this Project since 1970-71 for all the 5 sugarcane growing zones in the country brought about 2.7 times increase in sugarcane production and added significantly to the National Exchequer.
Different varieties made the dent during their productive periods.
At present following outstanding varieties went like wild fire among the farmers and increased the sugarcane and sugar productivity.
Based on the certain parameters and experiences, a brief account of impact assessed/estimated is given as under-
Tropical Region:
Impact analysis of Co 86032 as done by Ram et al, 2017 indicated that that the cane yield level was maintained at about 100 t/ha throughout the period except during drought year corresponding with the cultivation of CO 86032 in Tamil Nadu. The variety spread in almost all the states of Tropical India including Tamil Nadu, Karnataka, Maharashtra, Gujrat, unified Andhra Pradesh and Kerala. The variety covered 11.96 m ha area which approximately generated Rs. 20354 crore as additional monetary benefits.

The impact analysis of variety on sugar recovery with the base year of 1999-2000 revealed that with introduction of the variety Co 86032, the average sugar recovery increased to 9.45% compared to previous varieties (8.69%). The improvement in the sugar recovery was calculated in monetary value.
2- Subtropical Region:
Monitory benefits accrued to the farmers/millers by adoption of variety Co 0238
Additional cane produced due to increased yield of Co0238= 79.64 lakh tonnes and due to increased sugar recovery (%) was estimated to be 2,71,687.84 tonnes which amounted to be of Rs 815.06 crore The total value of additional sugarcane and sugar was worked out to be 2229.92+815.06=3044.98 crore. Thus, per ha additional income to the farmers comes to about Rs 34196/ha and additional income to the sugar mills comes around Rs 12499 on hectare basis.

Area expansion under improved varieties of the Project in Uttar Pradesh:
The trend of area expansion over total cultivation of sugarcane and depicted through Fig.1. The data as obtained from the office of Cane Commissioner Government of Uttar Pradesh clearly indicated that there has been an exponential growth of area brought under improved varieties developed under this project. The total cultivated area of AICRP varieties was increased from 5.93 % to 93.4% over the same period in Uttar Pradesh.

Spread of AICRP varieties during 2016-17 in subtropical India
The area under top four popular varieties (Co 0238, Co 0239, Co 0118 and Co 98014) in subtropical India comprising major sugar producing states (such as Punjab, Haryana, Uttar Pradesh and Uttarakhand) is about 9.97 lakh ha (41.8%) during 2016-17 crop season. Out of these four varieties, Co 0238 occupied about 8.63 lakh ha (36.19%) area in these four states and spread faster than other new varieties (Fig. 2 & 3).

Estimated benefits accrued due to trench method in Uttar Pradesh
This method is spreading fast in sugarcane growing areas of sub-tropics as growers can realize high input use efficiency and it provides ample scope for accommodating inter-crops between sugarcane rows. This method is ideally suitable for mechanized operation, less labour requirement, enhanced water use efficiency. Under this method of planting, farmers can obtain an average cane yield of 110 t/ha with a Cost benefit ratio of 2.15.
      
Impact analysis is based on the data available from department of U.P. Cane Commissioner Office. The total actual area of area planted during 2016-17 under 9 different zones (Saharpur, Meerut, Muradabad, Bareilly, Lucknow, Faizabad, Devipatan, Gorakhpur and Devria of UP. This method is very much suitable for planting of sugarcane as well as intercropping. Intercrop provides an additional income to grower mid season to sustain their monetary requirement instead of waiting for one year. Trench method of planting occupied an area of 41.88% of total sugarcane cultivated area in Uttar Pradesh. The approximate benefit from this technology was achieved as Rs 777.6 crore during 2015-16 to the growers. A total benefit expected to generate due to this technology will be more than 6 billion during 2017-18 in Uttar Pradesh. The detail information of analysis was presented as below:

Furrow irrigated raised bed system (FIRBS) method of planting:
Advantage of this technology is to minimize the yield loss due to delayed planting of sugarcane in the prevailing wheat-sugarcane system. Under this system of planting, sugarcane yield enhances by 30% and full yield of wheat as compared to sequential cropping wheat and sugarcane. Singh et al (2012) found that irrespective of the location, FIRB method fetched maximum average net return (Rs 81400 to 83027 /ha) at three locations.

Estimated benefits of FIRB in Western Uttar Pradesh
Estimated benefits due to FIRB method has been carried out on sugarcane plant crop of prominent wheat–sugarcane system popular in this western part of Uttar Pradesh (Saharpur, Meerut, Muradabad and few part of Bareilly zones) during 2016-17. The total monetary returns due to this technology expected to generate was Rs 900 crore to the growers of these zones. The details worked out as below:

Technological interventions and accomplishments (UP):
Stagnant cane yield and low sugar recovery became the identity of sugar industry in Uttar Pradesh over the years. There was a challenge to break this jinx with large scale adoption of technological interventions. This challenge was accepted and started working with deciding strategic plan encompassing identification of technological interventions, sensitization of stakeholders, deploying scientific manpower with active cooperation and logistic support from cane development department, Govt. of U.P. & sugar mills.
Unavailability of healthy seed material was major impediment in replacement of old cane varieties with newly released varieties. This was addressed with implementation of entrepreneurship development programme in seed cane production in farmers’ fields. Every year 2000 t of breeder seed of new cane varieties was produced and multiplied in nurseries and cane development department of state government of Uttar Pradesh ensured that it reached to the actual field of the farmers. In this way, scarcity of healthy seed material of new cane varieties was mitigated to a great extent. Before year 2012 State cane department was unwilling to recommend varieties tested under AICRP (S) and subsequently released by Central Variety Release Committee (CVRC). This issue was raised before State Government of U.P. and since 2012, CVRC released varieties was also added in the list of variety recommended for cultivation in the State.
This paved the way for large scale adoption of early maturing high sugar variety specially Co 0238 and CoLk 94184 in Uttar Pradesh. Introduction of these varieties changed the sugarcane and sugar production scenario of U.P. Dramatically another breakthrough in planting was achieved by the adoption of Trench method in about 2.0 lac ha leading to cane yield enhancement by 15-20 t/ha. Post-harvest losses remained major concern as it greatly impairs sugar recovery. This problem was addressed with spraying a mixture of sodium metasilicate (0.5%) + benzalkonium chloride (0.2%) solution on cane after harvest. This led to gain in sugar recovery by 0.3 to 0.5 units. The large scale adoption of different variants of sugarcane planters helped farmer to complete planting timely amidst labour scarcity and this also helped gain in yield by 8-10%. Likewise, introduction of ratoon promoter machine enhanced ratoon cane yield by 10-15%. Intercropping of pulses, vegetables, oilseeds and cereals with sugarcane gave ample opportunity to cane growers to earn extra income of Rs.50000 to Rs.200000 per ha.
Interface meetings with state cane department and sugar mills were organized regularly to decide operational plan for introduction of these interventions in farmers’ fields over large area. Those plans were implemented with active participation of all the stakeholders.
