Abstract

The major biotic stresses limiting productivity of pigeon pea includes weeds and various diseases like wilt, sterility mosaic virus, blight and pests as pod-borer, pod-fly in field and bruchids in field as well as in storage. Results of on farm trials revealed significant impact of adoption of management techniques of biotic stresses on seed yield, net profit and benefit cost ratio as compared to existing practices of pigeon pea cultivation. Scientific management of weed, pod borer and wilt was increased in seed yield by 26.2, 46.1 and 12.2%, while saving of seed by 23.6% from bruchids compared with existing practice, respectively. Among biotic management practices, higher additional cost was observed on weed management (Rs. 2,974 ha-1) and it was minimum on pod borer management (Rs. 798 ha-1) compared with existing practices. Accordingly, additional maximum net returns were obtained with pod borer (Rs. 24,805 ha-1) and minimum with wilt (Rs. 9,401 ha-1). Interventions of biotic stresses management were significantly influenced the output, use-efficiency, productivity and net gains of energy compared to existing practices. Maximum additional net energy gain was in management of weed (25,649 MJ ha-1) followed by pod borer (13,349 MJ ha-1), bruchid (8,390 MJ ha-1) and wilt (5,325 MJ ha-1). After harvest of second crop of pigeon pea, organic carbon, bulk density, infiltration rate and available N, P, K, S and Zn were significantly increased with weed and wilt management over existing practice. Management of biotic stresses by proper technologies increased the productivity of pigeon pea of three folds (2.12 to 2.33 t ha-1) compared to its average productivity of India and also increased economic benefits and energy outcomes.

生物胁迫管理技术对印度中部木豆产量、经济和能源指标的影响

限制鸽豆产量的主要生物胁迫包括杂草和各种病害，如枯萎病、不育花叶病毒、枯萎病和田间螟虫、田间蝇虫和田间及贮藏中的野鼠。农场试验结果表明，与现有的鸽豆栽培方法相比，采用生物胁迫管理技术对种子产量、净利润和效益成本比有显著影响。与现有做法相比，科学管理杂草、豆荚螟和枯萎病的种子产量分别提高26.2%、46.1%和12.2%，节省禾草种子23.6%。在生物管理措施中，杂草管理的额外成本较高(2,974 ha-1卢比)，豆荚螟管理的额外成本最低(798 ha-1卢比)。因此，豆荚螟的净收益最高(24,805 ha-1卢比)，而枯萎病的净收益最低(9,401 ha-1卢比)。与现有做法相比，生物胁迫管理干预措施显著影响了产量、利用效率、生产力和能源净收益。额外净能量增益最大的是杂草(25,649 MJ ha-1)，其次是豆荚螟(13,349 MJ ha-1)、野田鼠(8,390 MJ ha-1)和枯萎病(5,325 MJ ha-1)。在第二季收获后，与现有做法相比，杂草和枯萎管理显著提高了有机碳、容重、入渗速率和速效N、P、K、S和Zn。通过适当的技术对生物胁迫进行管理，使鸽豆的生产率比印度的平均生产率提高了三倍(2.12至2.33吨公顷)，并提高了经济效益和能源产出。
