“…The white grub is a destructive root-feeding insect that feeds on corn [ 6 ], potato [ 7 ], peanut [ 8 ], which may also become one of the pests that harm rice with aerobic cultivation. Such as white grubs were a major production constraint in upland rice production in North-Western Himalayas [ 9 ], Madagascar [ 10 ], Philippines [ 11 ]. The larvae usually damage young seedlings and roots of plants, sometimes resulting in significant yield losses [ 12 , 13 ] and cost input [ 11 ].…”

Background Rhizosphere microorganisms are vital in plants’ growth and development and these beneficial microbes are recruited to the root-zone soil when experiencing various environmental stresses. However, the effect of white grub (Maladera verticalis) larvae feeding on the structure and function of rhizosphere microbial communities of aerobic rice (Oryza sativa L.) is unclear. Results In this study, we compared physicochemical properties, enzyme activities, and microbial communities using 18 samples under healthy and M. verticalis larvae-feeding aerobic rice rhizosphere soils at the Yunnan of China. 16 S rRNA and ITS amplicons were sequenced using Illumina high throughput sequencing. M. verticalis larvae feeding on aerobic rice can influence rhizosphere soil physicochemical properties and enzyme activities, which also change rhizosphere microbial communities. The healthy and M. verticalis larvae-feeding aerobic rice rhizosphere soil microorganisms had distinct genus signatures, such as possible_genus_04 and Knoellia genera in healthy aerobic rice rhizosphere soils and norank_f__SC − I−84 and norank_f__Roseiflexaceae genera in M. verticalis larvae-feeding aerobic rice rhizosphere soils. The pathway of the metabolism of terpenoids and polyketides and carbohydrate metabolism in rhizosphere bacteria were significantly decreased after M. verticalis larvae feeding. Fungal parasite–wood saprotroph and fungal parasites were significantly decreased after M. verticalis larvae feeding, and plant pathogen–wood saprotroph and animal pathogen–undefined saprotroph were increased after larvae feeding. Additionally, the relative abundance of Bradyrhizobium and Talaromyces genera gradually increased with the elevation of the larvae density. Bacterial and fungal communities significantly correlated with soil physicochemical properties and enzyme activities, respectively. Conclusions Based on the results we provide new insight for understanding the adaptation of aerobic rice to M. verticalis larvae feeding via regulating the rhizosphere environment, which would allow us to facilitate translation to more effective measures.

“…Therefore this paper attempted to study the actual constrains both grain and seed production of paddy faced by farmers. Raj et al (2008) [7] undertook a study to find constraints of the farmers in cultivation of hybrid rice in Orissa. The primary data was collected from 208 rice growers to find out the constraints in hybrid rice cultivation.…”

The present study was conducted in Karimnagar purposively selected district of Telangana to identify the constraints perceived by farmers in grain and seed production of hybrid and open pollinated varities of paddy. From this district three Mandals i.e Vinavanka mandal, Manakondur mandal and Shankarpatnam mandal, were selected randomly among seed growing mandals for collecting primary data. From each mandal, one village was selected as a sample i.e Elbaka village (Vinavanka mandal), Utoor village (Manakondur mandal) and Kannapur village (Shankarpatnam mandal). Sampling was done covering all farm size groups. In every chosen village, a total of 60 farmers were selected for sampling. This selection was designed to encompass 20 farmers engaged in the production of Hybrid seeds, another 20 involved in the production of OPV seeds, and an additional 20 farmers focused on grain production. Consequently, the complete sample consisted of 180 farmers distributed among the three villages. Garrett' ranking technique was adopted to analyze the constraints as perceived by the respondents in Grain and seed production of paddy. The results revealed that major constraints perceived by rice growers were unfavourable weather conditions which ranked first with Garrett mean score around 85, followed by higher labour wage.
