A reduction in crop productivity in cultivable land and challenging environmental factors have directed advancement in indoor cultivation systems, such that the yield parameters are higher in outdoor cultivation systems. In wake of this situation, light emitting diode (LED) lighting has proved to be promising in the field of agricultural lighting. Properties such as energy efficiency, long lifetime, photon flux efficacy and flexibility in application make LEDs better suited for future agricultural lighting systems over traditional lighting systems. Different LED spectrums have varied effects on the morphogenesis and photosynthetic responses in plants. LEDs have a profound effect on plant growth and development and also control key physiological processes such as phototropism, the immigration of chloroplasts, day/night period control and the opening/closing of stomata. Moreover, the synthesis of bioactive compounds and antioxidants on exposure to LED spectrum also provides information on the possible regulation of antioxidative defense genes to protect the cells from oxidative damage. Similarly, LEDs are also seen to escalate the nutrient metabolism in plants and flower initiation, thus improving the quality of the crops as well. However, the complete management of the irradiance and wavelength is the key to maximize the economic efficacy of crop production, quality, and the nutrition potential of plants grown in controlled environments. This review aims to summarize the various advancements made in the area of LED technology in agriculture, focusing on key processes such as morphological changes, photosynthetic activity, nutrient metabolism, antioxidant capacity and flowering in plants. Emphasis is also made on the variation in activities of different LED spectra between different plant species. In addition, research gaps and future perspectives are also discussed of this emerging multidisciplinary field of research and its development.

Background: Black gram is one of the important pulse crops of the world and India is the major producer and consumer of pulses in the world. One of the main reason for low productivity of pulses is that they are cultivated mostly in areas with low soil moisture and poor soil fertility. In order to overcome such adverse conditions, low-cost techniques like seed hardening/pelleting are preferred. Seed pelleting provides package of nutrients that influences seed or soil at the seed-soil interface. Since the cost involved is very less, an attempt has been made to study the effect of botanical seed pelleting and foliar spary on growth and yield parameters in black gram cv. CO 6. Methods: Field experiments were conducted to evaluate the cumulative effect of botanical seed pelleting with pungam leaf powder @ 150g kg-1 and foliar spray of prosopis and moringa leaf powders with different concentrations (2%, 4%, 6% and 8%) on morpho physiological, leaf chlorophyll, gas exchange and yield parameters in black gram cv. CO 6 in the study. The observations on morpho physiological, leaf chlorophyll, gas exchange and yield parameters were recorded, statistically analysed and discussed here.Result: From the results, it was found that among the treatments, seed pelleting with pungam leaf powder @ 150 g kg-1 + foliar spray of prosopis leaf powder @ 6% recorded higher morpho physiological parameters viz., plant height (48.73 cm), number of branches plant-1 (8.78), dry matter production (14.83 g plant-1), chlorophyll ‘a’ (1.03 mg g-1), chlorophyll ‘b’ (1.11 mg g-1) and total chlorophyll content (2.14 mg g-1), photosynthesis and transpiration rates (27.33 mg CO2 m-2 s-1 and 10.60 mg H2O m-2 s-1), intercellular CO2 concentration and stomatal conductance (274.30 µ mol mol-1 and 0.82 mol-2 s-1). This treatment also recorded lower number of days to first flowering (23.23 days), earliness in 50 per cent flowering (30.12 days) and also recorded higher yield parameters such as lengthier pods, more number of pods plant-1, pod yield plant-1, number of seeds pod-1, seed yield plant-1, seed yield ha-1 and hundred seed weight of 5.60 cm, 26.30, 8.20 g, 7.30, 5.30 g, 795.12 kg ha-1 and 5.83 g, respectively as compared to other treatments. To conclude, seed pelleting with pungam leaf powder @ 150 g kg-1 + foliar spray of prosopis leaf powder @ 6% proved to be the best in enhancing morpho physiological, growth and yield parameters.

Background: Cowpea (Vigna unguiculata) is one of the most important legume crops cultivated throughout the world. Cowpea is used as food, feed, forage, fodder, green manuring and vegetable. It’s seed is a nutritious component in the human diet, as well as for livestock. Seed hardening and pelleting are seed enhancement techniques used to improve seed germination and seedling vigour and growth by altering the physiological state of the seed. This alteration may improve the vigor or the physiology of the seed by enhancing uniformity of germination. Seed enhancement techniques like hardening and priming include use of chemicals that trigger systemic acquired resistance or improve stress tolerance whereas the pelleting treatments improve seed handling and planting. They also enhance nutrient availability or provide inoculates by delivering materials needed during sowing, germination and seedling establishment. Hence in order to study the combined effect of seed hardening and pelleting on growth, yield and resultant seed quality of cowpea under natural saline conditions, the present study was taken up. Methods: The present field and laboratory investigations were carried out to study the effect of seed hardening, seed pelleting and their combined effect on growth, physiology, yield and resultant seed quality of cowpea under natural saline conditions. The fresh seeds of cowpea seeds cv. CO (CP) 7 were hardened with KCl @ 1%, CaCl2 @ 1% and both KCl and CaCl2 @ 1% and then the hardened seeds were further pelleted with pungam leaf powder @ 100, 150 and 200 g kg-1 of seed. Then the treated seeds were evaluated for their seed productivity and resultant seed qualities using untreated seeds as control. Observations on growth, leaf chlorophyll content, gas exchange parameters, yield and resultant seed quality parameters were recorded. Result: The experimental results revealed that among the treatments, seeds hardened with KCl @ 1 % + CaCl2 @ 1 % and pelleted with pungam leaf powder @ 200 g per kg recorded higher growth, yield parameters, leaf chlorophyll content, gas exchange parameters and resultant seed quality when compared to control and other treatments.

Cowpea (Vigna unguiculata) is an important legume crop. Investigations were undertaken to study the effect of seed hardening, seed pelleting and combined effect of seed hardening with seed pelleting on germination and seedling growth of cowpea under induced saline condition viz., EC4, EC8, EC12 and EC16. Cowpea seeds were hardened with KCl @ 1%, CaCl2 @ 1% and both KCl and CaCl2 @ 1% and hardened seeds were further pelleted with pungam leaf powder @ 100, 150 and 200 g kg-1 of seed. Observations on germination % and seedling parameters were recorded. The experimental results revealed that increased salinity reduced germination and seedling growth in terms of germination %, speed of germination, root length, shoot length, dry matter production and vigour index. However, hardening and pelleting treatments significantly increased all these parameters at all the levels of salinity when compared to control. Among the treatments, seeds hardened with KCl @ 1 % + CaCl2 @ 1 % and pelleted with pungam leaf powder @ 200 g per kg recorded higher germination % and all the seedling parameters when compared to control and other treatments.

The utilization and conservation traditional rice genotypes have attracted global attention. Optimization of DNA isolation protocol for genetic characterization of plants is a necessary and primary step. Over the recent years, next generation sequencing and microarray technologies have revolutionized scientific research, with their applications to high-throughput analysis of biological systems. Isolation of high quantities of pure, intact, double stranded, highly concentrated DNA is prerequisite for successful and reliable large-scale genotyping analysis. Therefore, standardization of DNA isolation is a basic requirement. Here we employed three methods of DNA isolation namely, Dellaporta, Hi-purA and modified CTAB techniques for isolation of genomic DNA from 25 indigenous rice genotypes. From the results, it was found that genomic DNA isolated by modified CTAB method to be the most appropriate for extracting high quality and maximum quantity DNA suitable for genotyping. The quality and quantity of the differentially extracted DNA was subsequently assessed by spectrophotometric measurements and gel electrophoresis.

Isolation of intact, double stranded, pure and non- contaminated genomic DNA is prerequisite for large scale genotyping analysis including DNA-banks. Three methods of DNA isolation (Dellaporta, CTAB and Hi-PurAg DNA isolation kits) from 25 black gram genotypes were compared in terms of the yield, purity, integrity, and stability of extracted DNA. Purity and quantification of isolated DNA samples was confirmed by using the UV nano-spectrophotometer at OD260/280 and the same is confirmed based by agarose gel electrophoresis. The CTAB method showed the best results followed by Hi-PurAg and Dellaporta method. The CTAB DNA extraction method was found to be the most efficient DNA extraction method, capable of providing high quality, pure and stable DNA and could be used for various molecular related works. All the 25 black gram genotypes for this research gave good yield of DNA from the established modified CTAB protocol.

Here an efficient protocol for micropropagation of black gram [Vigna mungo (L.) Hepper] cv. VBN 3 is reported. The deembryonated cotyledonary explants were cultured on MS medium containing different concentrations of plant growth regulators. The maximum frequency (72%) of direct shoot regeneration (devoid of callus phase), multiple shoot induction and shoot elongation was achieved from culturing the explants on MS medium containing 3.0 mg/l of 6-benzylaminopurine (BAP). Up to 65% of the regenerated shoots were rooted on MS medium containing 0.25 mg/l of á-naphthalene acetic acid (NAA) within 3 weeks after subculturing. The in vitro-raised plantlets were successfully hardened first under culture room conditions with 62% survival rate and then in greenhouse. The identified regeneration system could be efficiently used in various in vitro manipulation studies in black gram as well.

Cluster bean (Cyamopsis tetragonoloba (L.) Taub.) is an important legume crop. Investigations were undertaken to study the effect of seed pelleting with botanicals viz., Pongamia pinnata, Prosopis juliflora, Vitex nigundo and Albizia [email protected] 50, 100, 150 and 200 g kg-1 of seed on germination and seedling growth of cluster bean under induced saline condition viz., EC4, EC8, EC12 and EC16. The experimental results revealed that increased salinity caused harmful effects on germination and seedling growth in terms of germination %, speed of germination, root length, shoot length, dry matter production and vigour index. However, pelleting treatments increased these parameters with more pronounced effect by Pongamia pinnata leaf powder. Higher germination, growth and vigour of seedlings were recorded with Pongamia pinnata leaf powder treatment @ 200g per kg. The next best levels of vigour index was recorded in treatments with Pongamia pinnata leaf powder @ 150g per kg and Prosopis juliflora leaf powder @ 200g per kg only at no salinity and low levels and in high levels of salinity, Albizia amara leaf powder treatment @ 200g per kg performed as the nest best treatment.

Black gram [Vigna mungo (L.) Hepper] is the third most important pulse crop in India after chickpea and pigeon pea. Soil salinity is one of the major factor responsible for loss in agricultural production. Forty eight black gram genotypes were evaluated for salt tolerance with six different salinity levels viz., EC0, EC4, EC7, EC10, EC13, EC16 at early seedling stage. All the seedling parameters and salt tolerant index were investigated from four days old seedlings. From the results, it was found that there was a gradual decrease with increasing levels of salinity in all the genotypes studied. Seed germination and dry matter production showed more variations than other parameters studied for all the genotypes at different salinity levels. Based on the results, it may be concluded that the genotypes VNBG 017, AUB 3 AND AUB 20 were saline tolerant and VNBG 022, AUB 31 AND AUB 12 were susceptible to salinity.

Sesame is notable for its rich antioxidants and sesame oil is also familiar for its resistance to oxidation. The cultivation of sesame is usually restricted under abiotic stress conditions. Hence in order to study the performance of sesame genotypes to saline stress, an experiment was conducted to screen ten ruling varieties of sesame viz., CO1, SVR1, SVPR1, VRI 1, VRI 2, TMV 3, TMV 4, TMV 5, TMV 6 and TMV 7 at five different EC levels (EC 1, 2, 3, 4 and 5). Seedling observations namely, germination percentage, speed of germination, shoot length, root length and dry matter production were recorded. Among the genotypes, it was found that under higher saline conditions (EC5), VRI 1 recorded higher seedling length (2.0 cm), vigour index I (100) and vigour index II (1.15), whereas under normal condition, TMV 4 and CO 1 performed better. In general, there was a decrease in all the seedling parameters with increased levels of salinity. With STAR software, Multivariate analysis was done and on the basis of dendrogram, five clusters were formed and the cophenotic correlation co- efficient was found highest in Control (0.912) followed by EC 2 ( 0.829).

Field experiments were conducted to study the effect of fly ash seed pelleting in rice under aerobic agriculture which can be recommended for better crop growth and establishment. The study was conducted with three concentrations viz., 200, 250 and 300g per kg of seed. Observations on growth and yield parameters viz., plant height, dry matter production, leaf area, root weight, number of productive tillers/plant, number of grains/panicle, 1000 grain weight, and single plant yield were recorded. Gas exchange parameters viz., net photosynthetic rate, leaf transpiration rate, stomatal conductance and intercellular CO2 concentration were also recorded. The experimental results revealed that aerobic rice seeds treated with fly ash @ 250 g kg−1 performed better due to increased growth, gas exchange parameters and seed yield.

Tolerance for abiotic stress is a complex trait, which is controlled by various morphological, physiological and biochemical attributes. Identifying key mechanisms involved in tolerance will help to speed up the breeding efforts to develop tolerant genotypes. A study was conducted in generations of MAS 946-1 x ADT 43 in water limiting (aerobic) condition. 166 lines of F2 and 10 selected lines of F3 generations were evaluated during dry season of year 2010 and 2011 under aerobic condition in east coast region of Tamilnadu. Tolerant lines of F2, namely L77, L21, L34, L91, L60, L19, L93, L96, L37 and L94 were identified based on grain yield, which had good spikelet fertility. The tolerant ten lines with their parents were forwarded to next generation to measure the changes in the morphophysiological traits and biochemical activities on active tillering and maturity stage. The genotypes, showed enhanced level of chlorophyll content, relative water content, membrane stability index and antioxidant enzyme activities. A total of 56 alleles were detected in 10 F3s and two parents and the number of alleles per locus ranged from 3 to 7 with an average of 3.78 per locus. Among the primers used, RM224 identified more number of alleles and average PIC was 0.658. The dendrogram based on SSR marker analysis grouped the 12 lines into six clusters, where cluster II was the largest with four lines.
