“…This may be attributed for the increased plant height and reduced total number of productive branches in high density planting. These results are in agreement with Joshi et al(2019), Rajeshkumar et al (2017), Murad et al (2014, Kumar and Badiyala (2005).…”

Background: Redgram is an important food legume which is largely cultivated under rainfed condition. In India rainfed agriculture contributes 80% of the total pulses production and the projected requirement will be 39 million tons by 2050 which necessitates an annual growth rate of 2.2%. The productivity has to be increased from the present level of 834 kg ha-1 to 1200 kg ha-1. With adoption of suitable agronomic management strategies the productivity could be increased to meet our demand and achieve self sufficiency in production. Hence the current study was carried out to increase the productivity of redgram under rainfed condition.Methods: Field experiment was conducted in farmer’s field in Madurai district, Tamil Nadu during North East Monsoon season of 2019 to study the effect of improved agronomic manipulations on growth and yield of redgram under rainfed ecosystem. Agronomic management approaches viz., nipping of primary branches at 45 and 60 days after receipt of soaking rain, high density planting at 30 cm × 30 cm in addition to recommended spacing of 60 cm × 30 cm and foliar application of 1% PPFM spray were compared with farmer’s practice in the redgram variety Co (RG) 7. Pre monsoon sowing has been taken up and the rainfall received during the cropping period was 521.7 mm received in 31 rainy days.Result: The field experimental results revealed that adoption of agronomic manipulation at the appropriate stage of the crop has increased the productivity of redgram. Nipping of primary branches at 45th day of the crop significantly increased the total number of productive branches, number of pods plant-1 and recorded the maximum seed yield of 1512 kg ha-1 (72 per cent increase over farmer’s practice) under rainfed condition.

“…Combining farm yard manure with the above factors of production had reduced the B: C ratio slightly which suggested that it is a costlier input than nitrogen and iron sulphate with respect to monetary output per rupee investment under these inputs. The highest gross, net returns and B: C ratio were obtained by Joshi et al (2019) an application of higher rates of nutrients, i.e., with 125% RDF. Sui et al (2019) also reported significant economic benefits with manure in wheat.…”

Aim: This experiment was conducted to find out appropriate technical intervention for integrated management of nitrogen and iron chlorosis in irrigated groundnut in arid regions. Methodology: Two levels of farmyard manure, five levels of nitrogen and three levels of iron spray were applied in irrigated groundnut. Chlorophyll content, active iron content, periodic dry matter accumulation, oil content and yield, protein content and nutrient uptake by groundnut were studied. Most effective level of farmyard manure, nitrogen application and iron spray were identified for optimum management of the resources.? Results: The results showed that application of farmyard manure @ 15 t ha-1, nitrogen @ 60 kg ha-1 in two or three splits and foliar spray of FeSO4 @ 1.0 % in combination with citric acid @ 0.1% was found supportive in correcting iron chlorosis by increasing chlorophyll and active iron content, improving oil content and yield, protein content and nutrient uptake and ultimately enhancing net return by groundnut under irrigated conditions. Interpretation: Farmyard manure, higher dose of nitrogen in split application and foliar spray of iron is helpful in correcting iron chlorosis, improving growth, quality and nutrient uptake and increasing income of groundnut growers under irrigated condition in arid regions.

“…Bio-fertilizers enhance plant growth, including increasing the number of leaves, leaf area, length, shoot fresh and dry weight and root fresh and dry weight [32][33][34]. Additionally, bio-fertilizers can mobilize mineral elements from an unavailable to an available form, thereby increasing the availability of both micro and macro nutrients for plants [8,35]. Soil naturally contains beneficial microorganisms supporting plant nutrition, producing phytohormones, controlling phytopathogens and improving the soil structure.…”

Hydroponics is a contemporary agricultural system providing precise control over growing conditions, potentially enhancing productivity. Biofertilizers are environmentally friendly, next-generation fertilizers that augment product yield and quality in hydroponic cultivation. In this study, we investigated the effect of three bio-fertilizers in a hydroponic floating system, microalgae, plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF), combined with a 50% reduction in mineral fertilizer, on lettuce yield and quality parameters including antioxidants: vitamin C, total phenols and flavonoids. The treatments tested were: 100% mineral fertilizer (control 1), 50% mineral fertilizer (control 2), 50% mineral fertilizer with microalgae, 50% mineral fertilizer with PGPR and 50% mineral fertilizer with AMF. The research was conducted during the winter months within a controlled environment of a glasshouse in a Mediterranean climate. The PGPR comprised three distinct bacterial strains, while the AMF comprised nine different mycorrhizal species. The microalgae consisted of only a single species, Chlorella vulgaris. AMF inoculation occurred once during seed sowing, while the introduction of PGPR and microalgae occurred at 10-day intervals into the root medium. Our findings revealed that the treatment with PGPR resulted in the highest growth parameters, including the lettuce circumference, stem diameter and fresh leaf weight. The 100% mineral fertilizer and PGPR treatments also yielded the highest lettuce production. Meanwhile, the treatment with AMF showed the highest total phenol and flavonoid content, which was statistically similar to that of the PGPR treatment. Furthermore, the PGPR recorded the maximum range of essential nutrients, including nitrogen (N), potassium (K), iron (Fe), zinc (Zn) and copper (Cu). Thus, the inclusion of PGPR holds promise for optimizing the lettuce growth and nutrient content in hydroponic systems. In conclusion, PGPR has the potential to enhance nutrient availability in a floating hydroponic system, reducing the dependence on chemical fertilizers. This mitigates environmental pollution and fosters sustainable agriculture.
