AICRPS Objectives

1. Twenty-two Cooperative Centres of AICRP on Soybean have procured conserved and evaluated about 8800 germplasm accessions.

3. Problem of pod shattering in soybean is largely solved by development of several shattering-resistant varieties.
4. The inherent problem of poor seed longevity has also been overcome by way of developing a number of varieties free of such problem.
5. Promising extra early to early maturing variety viz. JS 95-60, Pratap soya 2 and CO-3 developed during the period under report, helped in increasing the system efficiency of soybean based cropping system and also in extending soybean to nontraditional areas.
6. Variety with low linolenic acid viz. VLS 59 has been developed.
7. Variety JS 97-52 tolerant to excessive soil moisture, ymv and root rot has been released.
8. Entry MACS 1188 with maturity of 98 days and yield potential of 24.75 q/ha has been identified for southern zone.
9. Two lines, EC 241778 and EC 241780 have been identified as donors for rust resistance.
10. Varieties, JS 335, Indira Soy 9, NRC 37 and JS 93-05 have been identified as donors for bacterial pustule resistance.
11. Genotypes, SL 744 and MACS 1184 for pod borer (Cydia ptychora), MACS 1140 and AMS 1 for stem fly, NRC 80 for leaf miner (Aproraema modicella), MACS 1188 for leaf folder (Hedylepta indicata) were identified as resistance sources.
12. Genotypes MAUS 295, JS 20-09, RKS 45, JS 20-06, NRC 80, AMS 1 and DSb 12 have been identified as potential donors for multiple resistances against major insect pests.
13. Several rust tolerant and yellow mosaic resistant lines/varieties and varieties having resistant to other major diseases have been developed/identified.
14. Breeder seed was produced as per the DAC indent every year. In the year 2010-11 a total of 18327.16 quintal breeder seed was produced.
15. New location-specific biotic menaces viz. soybean rust and Yellow mosaic virus was successfully managed through recommendation of comprehensive integrated management schedule.
16. Integrated disease management for important diseases of soybean including use of bio-control agents and fungicides was developed and demonstrated in farmers fields in different zones.
17. Neem products and ITK were recommended for effective management of diseases.
18. Several insect resistant/tolerant varieties have been identified.
19. Integrated pest management (IPM) including bio-pesticides and insecticides for major insect-pests was standardized and successfully demonstrated in farmers’ fields in different zones.
20. Tank-mix combination of Bacillus thuringiensis based biopesticide with monocrotophos gave better pest complex management with higher yields.
21. New effective insecticides, Rynaxypyr 20 SC @ 100 ml/ha and Spinosad 45 SC (Spinosyn A 50% min. + Spinosyn D 50% max.) 125 ml/ha have been recommended for the management of major insect-pests of soybean
22. Optimum production technology for soybean based cropping and intercropping systems involving IPNM, IPM, IWM for different agro-ecological regions were identified and recommended.
23. Zone specific land configuration systems (Ridge and furrow, broad bed furrow and conservation furrow) and crop geometry for in situ moisture conservation have been standardized and recommended.
24. Low input technology such as minimum tillage, organic agriculture, effective native strains of bio-agents were identified and recommended.
25. Optimum plant population, sowing time, recommended fertilizer and micronutrient doze and other agronomical practices have been standardized for different zones across the country.
26. Conservation furrow at definite interval have been recommended for efficient moisture conservation in soybean for different zones.
27. Ridge and furrow method of sowing in North Eastern Zone and raised bed planting in Northern Plain Zone along with 62.5 kg seed rate/ha was recommended.
28. Intercropping of soybean with pigeonpea (arhar) for rainfed situation and soybean with maize for irrigated situation was found highly beneficial. Farmers are increasingly adopting these intercropping systems.
29. Soybean based cropping systems for different agro-ecological regions have been identified and recommended.
30. Integrated use of crop residue @ 5 t/ha + FYM @ 5 t/ha + Zn @ 5 kg/ha along with RDF resulted in the maximum yield of soybean as well as wheat.
31. Broad bed furrow and ridge sowing has been found promising in some regions over flat bed sowing.
32. Varieties suitable under moisture stress conditions have been identified.
33. Application of RDF + FYM @ 5 t + Zn @ 5 kg/ha gave promising results for soybean based intercropping system.
34. Pre-plant incorporation and pre-emergence weedicides have been recommended for effective management of weeds.
35. Recently, a new pre-emergence herbicide Diclosulam @ 22 g a.i./ha was recommended for effective control of major weeds of soybean.
36. Integrated nutrient management technology was standardized and recommended by suitably integrating organic and inorganic sources.
37. Adoption of minimum tillage was found to reduce cost of cultivation in specific locations.
38. Results of FLDs conducted in farmers field across the country revealed that soybean productivity can be enhanced to the tune of 30.72% by adoption of full package of         practices by the farmers.
39. A positive response of Bradyrhizobium and phosphate solubilizing bactetria on growth and development of soybean was established.
40. Bradyrhizobium strains viz. Pantnagar 2 in combination with BJ 2 strain and others were identified for improving nitrogen fixation and productivity.
41. Co-inoculation of B. japonicum either with VAM fungi or PGPR or 60 kg P2O5 or 60 kg K2O + 5 kg boron gave promising results.
42. Use of zinc and molybdenum along with Bradyrhizobium japonicum was also found promising.
43. Two new Rhizobial strains having better nodulating ability have been identified and registered with IMTEC, Chandigarh.
