A study was conducted on Production potential of Maize (Zea mays L.)-Based Intercropping systems at the experimental farm of School of Agricultural Sciences and Rural Development (SASRD) Nagaland University, Medziphema Campus, under rainfed condition during 2015 and 2016. The treatments comprised of different row ratios i.e. (1:1), (1:2), (2:1) and (2:2) respectively of maize intercropped with perilla, sesame, ricebean and soybean. The experiment was laid in RBD with 3 replications and 21 treatments. Sole maize recorded the best with regard to growth parameters like plant height, leaf area plant-1 and stem thickness with its pooled at 315.25 cm, 2.23 and 2.44 cm. While in regard to yield parameters sole maize recorded superior than all other sole crops with its pooled in respect to number of cobs plant-1 (1.92), cob weight (g) (144.17 g), number of grains cob-1 (555.67), shelling percentage (80.83), grain yield (4280.06 kg ha-1) and stover yield (5296.82 kg ha-1). Among the different intercropping systems paired rows (2:2) ratios of maize+soybean performed significantly better in terms of yield with pooled of (1565.65 kg ha-1) and production efficiencies viz.

Background: A field experiment was conducted at the Experimental Research Farm of School and Agricultural Sciences and Rural Development (SASRD), Nagaland University, during the Kharif season of 2017 and 2018 to study the effect of sulphur and zinc fertilization for biofortification in soybean (Glycine max L. Merrill) under Nagaland condition. Methods: The experiment was laid out in a Factorial Randomized Block Design (RBD) with 15 treatments combinations viz sulphur (0 kg ha-1, 20 kg ha-1 and 40 kg ha-1), zinc (0 kg ha-1, 5 kg ha-1, 10 kg ha-1, 15 kg ha-1, and 20 kg ha-1) replicated thrice. Result: The results obtained showed that the plant growth and yield attributes were significantly influenced by the treatment combination of S20Zn20. The application of 20 kg S ha-1 showed higher plant height, number of leaves and branches per plant, shoot dry weight, leaf area index (LAI), crop growth rate (CGR), number of nodules and was found to be quite comparable with the treatment of 40 kg S ha-1. The zinc fertilization of 20 kg Zn ha-1 showed greater response by the plant and showed increased plant height, number of leaves and branches per plant, shoot dry weight, leaf area index (LAI) and number of nodules at par with 15 kg Zn ha-1. A higher number of pods (40.48 and 40.89), seed yield of (1.07 t ha-1 and 1.10 t ha-1) and stover yield (1.97 t ha-1 and 2.02 t ha-1) were observed in 20 kg S ha-1 and 20 kg Zn ha-1 fertilization respectively as compared to the other levels of treatments. However, the length of pods, number of seeds per pod, test weight and harvest index did not differ significantly by the treatments.

A series of 1,3‐oxazine derivatives were synthesized by a one‐pot three‐component (ie, phenol, formaldehyde, amine) method where SiO2 bonded with NaCl was used as a reusable, more efficient, easily prepared, and available solid catalyst. The reactions were also carried out at room temperature for greener approach. in vitro studies for the synthesized compounds were also done against two gram‐positive (Bacillus subtilis and Staphylococcus aureus) and two gram‐negative bacteria (Escherichia coli and Klebsiella pneumonia) to check for their applicability as an antibacterial agent where some of the synthesized compounds gives the best antibacterial activity against selected bacterial strains. Streptomycin was used as a standard control for all the microbial test.
