Studies on performance of transplanted Finger Millet in Surahonne based Agroforestry System Under Varied Nutrient Level Practices
Field experiment was conducted during kharif-2018 at Bio fuel park Madenur, University of Agricultural Sciences, Bangalore. The experiment comprised of seven treatments with three replications laid out in randomized block design. The experimental soil was red sandy loam with neutral in reaction (pH 6.8) and the electrical conductivity was normal (0.26 d Sm-1 at 25 °C). The available nitrogen present in the soil was medium (337 kg ha-1) , the available phosphorus was high 34 kg ha-1 and medium potassium 290 kg ha-1. The results revealed that significantly higher finger millet grain and straw yield (2792 and 5164 kg ha-1, respectively) was recorded with (T7) application of 75% N equivalent through neem cake+ 25% through RDF + 2% 19:19:19 water soluble foliar spray. The higher yield of finger millet was attributed due to higher number of tillers (5.30 plant-1), total dry matter (35.52 g plant-1), ear length (6.98 cm) and 1000 grain weight (3.68 g). It was on par with (T2) application of 75% N equivalent through pongamia cake + 25% through RDF + 2% water soluble 19:19:19 foliar spray (2606 and 5052 kg ha-1, respectively) and recommended package of practice(T1) (100:50:50) N, P2O5, K2O kg ha-1 + FYM @ 10 t ha-1 (2504 and 4973 kg ha-1, respectively). Lower grain and straw yield (1888 and 3549 kg ha-1, respectively) of finger millet was recorded with (T4) application of 25% N Equivalent through pongamia cake+ 75% through RDF + 2% water soluble 19:19:19.

Effect of Magnesium on Cannabis Biomass Yield and Cannabinoids Content: Evaluating Different Application Rates and Methods
Magnesium deficiency (MGD) is a severe problem in plants. Magnesium (Mg) is one of the important nutrients involved in many enzymatic activities and rarely studied in cannabis. In this study, the effect of application of different concentrations (0.75 ml L-1 of ‘Advanced Nutrients Bud Factor X’ equivalent to 3.75 mg L-1 of Mg, 2ml L-1 of ‘Advanced Nutrients Bud Factor X’ equivalent to 10 mg L-1 of Mg, and 4ml L-1 of ‘Advanced Nutrients Bud Factor X’ equivalent to 20 mg L-1of Mg), and methods of application (Soil Drench vs. Foliage Application) of magnesium was studied on useable biomass yield and cannabinoids content on two chemovars (high CBD and high CBG) of Cannabis sativa L. Plants grown through feminized seeds were divided into two groups, control (no treatment) and treated with different concentrations of Mg (10 mg L-1 soil drench, 20 mg L-1 soil drench and 3.75 mg L-1 foliage spray). Plants of both groups were grown side by side in an identical environmental condition in a polytunnel and, were watered and fertilized normally. The application of different concentrations of magnesium began in the first week of flowering and continued until maturity. Both groups of plants were harvested at maturity, processed for usable dry biomass, and compared for biomass production per plant and cannabinoid content. Our results show that among all treatments (Soil Drench and Foliage Application), the maximum increase in cannabis biomass per plant in CBD-rich chemovars was achieved with the application of 10 mg L?1 Mg, whereas the highest increase in biomass per plant in CBG-rich chemovars was achieved with the application of 20 mg L?1 Mg. On the other hand, the maximum increase in CBD content per plant (in the CBD-rich chemovar) and CBG content per plant (in the CBG-rich chemovar) was observed with the application of 10 mg L?1 Mg to the soil, compared to the ‘control’ plants.

Isolation and Identification of Soil-born fungi from Citrus Orchards of ICAR-IARI, New Delhi, India
Most of the soil-born fungi are pathogens and cause diseases to plants. Susceptibility of plants to these soil borne diseases is the most concerning part which present a common threat to agricultural production and productivity. In the present study, the soil samples were collected from different citrus orchards of ICAR-IARI, New Delhi. The isolation of fungal isolates was done on Sabouraud dextrose agar (SDA) media by following serial dilution and spread plate technique at temperature and incubation period of 300C and 24 hours respectively. Based on the morphological and gram staining, a total of 9 different species of soil-borne fungi were isolated, among which Rhizopus and Mucor were dominant. Further it was found that 3 different species of Aspergillus viz. A. versicolor, A. glaucus and A. flavus were also identified. All three species of Aspergillus are considered as pathogens of important crops and A. flavus is able to produce potent mycotoxins. It was concluded that the soils of citrus have a good diversity of fungal species and some of the isolates were pathogenic as per the available scientific literature. Hence the research provides the early alarm for the presence of pathogenic fungi that can be detrimental to crops and thus the loss can be prevented by taking early preventive measures.

Profiling and Quantification of Phytocannabinoids for the Classification of Cannabis sativa L. Varieties
Whether cannabis is one species or more, is a long-standing topic of debate within the research community. However, according to the current scientific consensus, cannabis is considered as a single but highly variable species, Cannabis sativa L. On the other hand, cannabis can also be classified based on its cannabinoid profile, which is more relevant when the goal is to develop cannabis-based phytopharmaceuticals. Once chemically analyzed, screened, and selected, high-yielding mother plants can be mass-propagated through micropropagation or vegetative propagation to ensure batch-to-batch consistency, as well as to maintain quality and efficacy. In this study, plants of different cannabis varieties/chemovars were grown from seeds. Once identified, male plants were removed from the growing area, while only female plants were retained for future research. For the initial screening, biomass samples collected from female plants were analyzed for the cannabinoid content using GC-FID, and the elite mother plants from each variety were further selected. Mother plants were mass-propagated through micropropagation and grown outdoors until they reached maturity. The harvested biomass samples of these plants were then analyzed using GC-FID and NMR spectroscopy. Based on the results, plants were classified into three distinct chemotypes: high THC, intermediate, and high CBD, with clear differentiation. The living germplasm of these plants are further conserved in-vitro for future use.

Instability analysis and forecasting using ARIMA Model in Fruit Production in India
India is a significant agrarian nation, with 77% of India’s population living in rural areas and 90% of that rural population employed directly in agriculture. The country’s main fruit crops include bananas, guavas, papayas, jackfruits, pineapples, mangoes, and others. The primary aim of this study is to forecast the major types of fruit production in India by applying the Box-Jenkins Autoregressive Integrated Moving Average (ARIMA) model using time series models during 1961-2020. The findings indicate that the best ARIMA models for predicting the production of bananas, apples, grapes, mangosteens, guavas, and pineapples are ARIMA(1,1,0), ARIMA(1,1,4), and ARIMA(1,1,5). The comparison between the original and forecasted series, presented in a similar manner, indicates that the fitted model reliably forecasts fruit production in India. In the present investigation aim to analyze the instability of fruit crops in India and to estimate the decomposition analysis of fruit crops specifically in India. To achieve these objectives, secondary data spanning 60 years were analyzed using statistical tools such as the Coefficient of Variation (CV) and Cuddy Della Valle’s Instability Index (CDVI).

Genetic Analysis of Proso Millet (Panicum Miliaceum L.) Genotypes for Morpho-Physiological and Biochemical Characters
This study examined 48 proso millet genotypes to evaluate genetic variability, diversity, and trait associations across 15 distinct characteristics. Traits such as yield per plant, peduncle length, leaf width, flag leaf length, and plant height exhibited substantial genetic variability with high heritability and genetic advance, indicating that selection for these attributes would be both efficient and effective. Genetic divergence analysis categorized the genotypes into five distinct clusters, demonstrating a broad range of genetic diversity. The clustering pattern revealed that geographical origin did not correspond with genetic diversity among the studied genotypes. Cluster IV contained the highest number of genotypes (15), while Cluster V had the fewest (2). The greatest inter-cluster distance was observed between Cluster I and Cluster V, suggesting that crossing genotypes from these clusters could potentially produce superior transgressive segregants in advanced generations. Among the traits analyzed, Plant Height (PH), Flag Leaf Length (FLL), Flag Leaf Width (FLW), Leaf Width (LW), and 1000 Seed Weight (TSW) exhibited the most significant direct impact on yield per plant (YPP), rendering them essential targets for breeding programs focused on yield enhancement. Furthermore, the correlation analysis corroborated these findings, reinforcing their importance in improving yield potential.
