GROWTH, FLOWERING AND FRUITING BEHAVIOR OF GUAVA UNDER ULTRA HIGH DENSITY ORCHARDING SYSTEM IN NORTH EASTERN INDIA
In 2017, guava plantlets were planted at different densities to study their growth, flowering, and fruiting behaviour under ultra high density system of orcharding. The experiment was laid out at the Horticultural Research Station, Assam Agricultural University, India, in Factorial Randomised Block Design. The plants accommodated at lower density exhibited improved growth, all the plant growth attributes except the plant height tended to increase noticeably with the decrease in plant density from 10000 to 4444 plants ha-1. The canopy spread in east–west direction was larger in the population density of 5000 plants ha-1 while the north–south canopy spread was greater among plants with density of 4444 plants ha-1. The significantly higher number of flowers, fruits per branch, highest fruit set and lowest fruit drop was recorded in widely spaced population during both winter and rainy seasons of the investigation. Although the rainy season crop bears more flowers and fruits, the fruit setting was higher in the winter season during both years of experimentation. The nutrient level also significantly influenced plant vegetative and reproductive growth, an increased trend was observed with increasing nutrient level, and among all, the highest level of nutrient (70:45:35 g NPK plant-1 for first year and 130:75:65 g NPK plant-1 for second year) exhibited considerable superiority.
Development of a Low-cost Autonomous Driving System for Soil Sensing
This paper develops an autonomous-driving platform to check the condition of soil in agricultural areas. The platform, which runs on an electric motor equipped with a caterpillar, uses an RTK-GPS module for accurate position estimation to obtain position coordinates with an accuracy of several centimeters and integrates an Inertial Measurement Unit (IMU) sensor to obtain precise angle values. An algorithm is developed to control the autonomous-driving platform and proceed with the planned route to the optimal route. In order to smoothly and accurately control the direction of a small tractor, an extended Kalman filter control algorithm is used to develop an algorithm that can automatically achieve more stable path driving by eliminating instability and risk caused by rapid steering control. The route is set by combining the RTK-GPS module and IMU module, which provide precise location coordinates, and an environment is provided so that the soil contamination sensor can operate at an accurate location at regular intervals within the driving route.
A meta-analysis of the dynamics and distribution of the donkey population in India
The donkey, formerly thought of as the common man's tractor, is no longer a highly prized animal in many areas of India because mechanisation has replaced animal power in India's transportation, agriculture, and other commonplace tasks. Equine power, particularly donkey power, is still used in difficult hilly terrains where motorised vehicles cannot go. India is home to roughly 0.12 million "Beast of Burden" donkeys. Indian donkeys are present in a variety of agroclimatic regions. The sharp decreasing trend seen in the Livestock Census has made it necessary to learn about the present state of donkeys. The population of donkeys has decreased by 61.2% since the last census in 2012, which is blamed on a number of issues, including the mechanisation of brick kilns, disease outbreaks, illegal trade and slaughter, low-income generation, and other societal problems. However, the majority of India's donkeys are concentrated in rural areas, where they serve as a means of subsistence for those who are impoverished. This study focuses on the population dynamics and geographic distribution of donkeys in order to prepare future initiatives to preserve the biodiversity of this significant equid germplasm.
Experimental evidence of mortality in honey bee, Apis mellifera L. (Hymenoptera: Apidae), workers caused by entomopathogenic nematodes, Steinernema abbasi and Heterorhabditis indica (Nematoda: Rhabditida)
This study was conducted to test whether the entomopathogenic nematodes, Heterorhabditis indica and Steinernema abbasi, used in biological pest management programmes could potentially have adverse effects on honey bee, Apis mellifera workers. EPNs are considered as safe bio-agents which might be used as a bio-pesticide against the greater wax moth, Galleria mellonella infesting honeybee colonies without causing any harm to adult bees and brood. However, exposer of bee workers to Steinernema abbasi and Heterorhabditis indica under laboratory conditions confirmed the susceptibility of bee workers to nematode infection without successful recycling. The results obtained showed % mortality of bee workers exposed through feed (indirect exposer) were 37% and 61%, respectively, while for direct spray, the mortality percentages were 20% and 33% for H. indica and S. abbasi, respectively, under laboratory conditions. This study concluded that application of both S. abbasi and H. indica may not be the safe options to be used in any situation where honeybee workers or colonies are likely to be exposed during bio-control interventions.
Plant growth promotion and antimicrobial activity of bud endophyte Bacillus pumilus PM2 associated with ethnomedicinal plant Spilanthes acmella (L.) L. from biodiversity hotspot of Arunachal Pradesh, India
This study aims to identify and develop a novel inoculum of highly resistant endophytic bacteria associated with Spilanthes acmella (L.) L. from the unexplored forest rich region of the Eastern Himalayan region of Arunachal Pradesh. These bacteria can adapt to the local soil conditions and offer several benefits to plants. These isolates were obtained through surface sterilization and assessed for their ability to promote plant growth and combat fungal pathogens like Sclerotium rolfsii and Sclerotinia sclerotiorum. The most effective isolate PM2 was tested using a plant inoculation assay to measure its impact on the growth of a local rice cultivar. The antimicrobial compounds produced by this isolate were identified using Thin Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS). The isolate was further identified through 16S rRNA gene sequencing.
