ABSTRACT
Many farmers are incorporating green manuring into their practices as a result of the growing issues facing agriculture, such as climate change, extreme weather events, soil deterioration, and land contamination due to the excessive use of chemical fertilizers. Growing green manure is a useful and affordable way to ensure the long-term productivity of agricultural soils. Given the significant loss of soil fertility caused by improper agronomic practices, human-induced land degradation is extremely serious. Due to their positive effects on the physical, chemical, and biological quality of the soil as well as the proper justification of soil fertility, green manures can play a significant role. Utilizing green manure is one of the trends in environmental protection that aids in the agricultural sector’s transition to sustainability by conserving resources and meeting consumer demand for food. Modern farmers are faced with a number of challenges as they try to transition to productive and ecologically friendly practices. To preserve soil fertility while utilizing less chemicals is one of them. Green manure crops could be a potential answer to this issue. Back in ancient times, farmers learned that this method had a positive effect on the soil. Thus, for growers who want to reduce the use of hazardous chemicals for soil fertilization, green manure is indispensable. In terms of operations, many farmers must employ green manure to reduce the overuse of chemical fertilizers in agriculture.

ABSTRACT
The scarce rainfall zone of Andhra Pradesh faces problems of inadequate moisture availability and proper crop stand for successful crop production that results in partial or total failure of crop with occurrence of mild to severe drought. Therefore, adoption of proper spacings and proper land configurations are required in order to reduce yield losses. So, the purpose of this study is to find optimum spacing and suitable land configuration for maximizing the groundnut yield. A field experiment was conducted to study the performance of groundnut (Arachis hypogaea L.) to different land configurations and spacings on sandy loam soils at College Farm, Agricultural College, Mahanandi during rabi, 2021-2022. The experiment was laid out in strip plot design with two factors each having four treatments and replicated thrice. The results revealed that the growth parameters viz., plant height, dry matter accumulation, LAI and number of branches were recorded higher with the land configurations corrugation, flat bed with crop compaction, ridges and furrows and flat bed with crop compaction, respectively. Spacing 30 x 10 cm recorded higher plant height, dry matter accumulation and LAI and higher number of branches were observed with 60 x 10 cm spacing. Among different interactions treatment combination ridge and furrow with 30 x 10 cm spacing, flat bed with crop compaction with 30 x 10 cm spacing, flat bed with crop compaction with 60 x 10 cm spacing has recorded higher plant height, dry matter accumulation, LAI and number of branches, respectively. Higher pod and haulm yields were observed with the land configuration flat bed with crop compaction and 30 x 10 cm spacing. Treatment combination flat bed with crop compaction and 30 x 10 cm spacing has recorded higher pod and haulm yields.

ABSTRACT
The field experiments were carried out in a randomized block design during rabi seasons of 2016-17 and 2017-18, to evaluate the effect of newer insecticide molecules against insect and mite pests of potato during rabi season in Karnataka, India. There were 10 treatments including an untreated check and replicated thrice. Kufri Pukhraj was used as a test variety in a plot size of 3 × 4 m with a spacing of 60 × 20 cm. Two sprays were taken up, the first being given 30 days after sowing and another 15 days later based on the economic threshold level of the pests. Among the insecticides evaluated, cyantraniliprole 10 OD @ 0.20 ml/l proved its excellence against shoot borer and defoliator by recording 65.27 and 72.69 per cent protection, respectively which was followed by spinosad 45 SC @ 0.20 ml/l (51.96 and 62.40%, respectively). Whereas in the case of sucking pests viz., aphid, leafhopper and whitefly, diafenthiuron 50 WP @ 1.00 g/l proved its superiority by documenting 78.00, 77.27 and 57.79 per cent protection, respectively. The highest percent protection over control against thrips was afforded by spinosad 45 SC @ 0.20 ml/l (67.54 %) followed by cyantraniliprole 10 OD @ 0.20 ml/l (58.62 %) and emamectin benzoate 5 SG @ 0.25 g/l (49.70 %). In respect of mites, the treatment with spiromesifen 22.9 SC @ 1.00 ml/l registered the highest protection of 70.38 per cent. The treatment cyantraniliprole 10 OD @ 0.20 ml/l recorded highest net returns of Rs. 2,65,897/ha with benefit-cost ratio of 7.47 followed by spinosad 45 SC @ 0.20 ml/l (Rs. 2,38,558/ha and 6.60) and emamectin benzoate 5 SG @ 0.25 g/l (Rs. 2,34,400/ha and 6.72).
