A field experiment was conducted at Product testing Unit Agronomy, Department of Agronomy, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur to evaluate the effect of foliar application of seaweed saps (K-sap from Kappaphycus sp. and G-sap from Gracilaria sp.) at different concentrations with recommended dose of fertilizer (RDF) on growth and yield of maize in sandy clay loam soil of Kymore plateau. The foliar spray of K-sap and G-sap at 2.5, 5.0, 7.5 and 10.0% v/v with 100% RDF and 6.25% v/v of K and G-sap with 50% RDF was performed thrice (at 25, 50 and 75 Days after sowing). Results revealed that application of K-sap or Gsap at different concentrations along with RDF significantly enhanced the plant growth parameters and yield attributes. In general, gradual increase in growth parameters, yield attributes and yields were observed with increasing the concentration of K-sap or G-sap. The highest grain and stover yields were recorded under the application of 10% K-sap with 100% RDF, resulting in 34.78 and 20.12% during 2012 and 18.32 and 23.60% increases during 2013, respectively over control (water spray with 100% RDF) and closely followed by 10% G-sap with 100% RDF.
Momordica balsamina L. commonly known as the Balsam apple is an under-exploited cucurbit vegetable occurs wild type in nature which offers various dietary and nutraceutical properties. It is an annual to perennial, tendril-bearing herb, native to tropical regions of Africa. Since the crop occurs in wild forms, the variation exists among the genotype is limited. For the improvement of plant characteristics in diverse crops, mutation breeding has been extensively applied. In the present study, treated population was evaluated to study the extent of genetic variability and character association on growth and yield parameters in M1 and M2 generation of Momordica balsamina L. The results revealed that high heritability was exhibited by vine length at harvest, number of branches per plant at harvest, stem diameter, leaf area, number of fruits per plant, fruit girth, lycopene content, β-carotene content and ascorbic acid content. As per the character association studies, fruit yield per plant showed highly significant and positive association with number of fruits per plant, fruit weight, fruit length and days to first flowering. Whereas, highly significant but negative association was revealed by number of branches per plant at harvest, stem diameter and days to 50 per cent flowering among mutant population. Whereas, vine length at harvest, number of fruits per plant, fruit weight, fruit length and fruit girth recorded highest positive direct effect on fruit yield per plant. While, number of branches per plant at harvest, stem diameter and days to 50 per cent flowering exerted negative direct effect on fruit yield per plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
