Project sites

Project outreach & trial status

In 2018, project have marked its presence in Northern, Central and Southern zones of India. Project sites are strategically placed all across the major cotton growing belts of India. Continuing with Madhya Pradesh, Maharashtra and Odisha from 2017-18, SGF trial sites and activities are further extended to the states of Rajasthan, Gujarat and Andhra Pradesh in 2018-19.

In comparison to 25 trials in implemented during growing season 2017-18, first year of SGF Phase II have witnessed over five-fold increase in number of trials amounting to a total of 155 trials conducted across 6 states 2018-19 cotton growing season. This year, out of total trial conducted across the different states, majority of trials are established in Madhya Pradesh (54%) tops the list followed by Maharashtra, Odisha, Gujarat with least number of trials in Rajasthan and Andhra Pradesh (2%).

SGF trials

1. On-Station Cultivar Evaluation Trials (CET)

All trials are conducted under organic farming inhomogeneous fields that represent the majority of farmers growing conditions and soil types. Before starting field trials, breeding material and cultivars need to be tested for Bt-contamination with strip test. Minimum of 20 cultivars and breeding lines shall be tested, including long fiber G. arboreum as well as G. hirsutum cotton and commercial F1 hirsutum hybrids as a check. On-station trials need to be conducted as a randomized complete block design with 2 replications and 4 or 5-row per plot. Plant density varies according to soil type: under fertile soil with summer sowing and irrigation sowing should be done at the spacing of 3 x 1 feet (21 plant per row) or 3 x 2 feet (11 plants per row) for F1 hybrids and for shallow soil with monsoon sowing and rainfed conditions with spacing of 2 x 1 feet (21 plant per row), respectively. To avoid mixtures during harvest, the plots are separated by one border row of red-leaved cotton or different cotton species.

2. On-Fam Baby Trials

On-farm baby trials are conducted with 7 entries out of which four entries were common to all the partners, whereas for remaining 3 partners have the option to choose preferred genotype including at least one arboreum, one or two hirstusm/herbaceum, one hirsutum hybrid and one check in 2 replications as 2- to 4-row plots with minimum 100 plants per cultivar.

3. On-Fam Pilot Trials

For On-Farm Pilot trials at farmers field, 0.1 acre of suggested promising lines either a hirusutum variety, arboreum hybrid or arboreum variety is planted in comparison with present commercial hirusutum hybrid/variety on the same field.
