Background: The ambition of nanoparticles in agriculture is to reduce the amount of spread chemicals, minimize nutrient losses in fertilization and increased yield through pest and nutrient management. The recent advances in nanotechnology and its use in the field of agriculture are astonishingly increasing therefore it is tempting to evaluate the effect of different nanoparticles on growth and yield contributing characters in tomato. Methods: A field experiment was conducted at College of Horticulture and Forestry, Jhalawar during Rabi season 2019-2020 which consisted of 13 treatments of three nanoparticles, viz. Zn, Fe and Ag at four different concentrations. Result: The results revealed that among different concentration of nanoparticles, seed treated with 800 ppm Zn NPs solution for 4 hours significantly improved the growth and yield characteristics in comparison to control. Similarly, Fe and Ag NPs also significantly influenced the growth and yield attributes but at increasing ...

A field experiment was conducted during <italic>kharif</italic> season 2013 to estimate the correlations and path coefficients for ten quantitative characters among 72 cowpea germplasm. Seed yield per plant had positive significant correlation with days to 50% flowering, plant height, primary branches per plant, pods per plant, pod length, seeds per pod and 100-seed weight at both genotypic and phenotypic levels. Path coefficient analysis revealed that primary branches per plant and 100-seed weight had high direct positive effect on seed yield per plant at both genotypic and phenotypic levels. Pod length, days to maturity, 100 seed weight and pod wall proportion had high positive direct effects on seed yield per plant at only genotypic level. Correlation and path analysis indicated that for increasing seed yield in cowpea direct selection should be carried out for higher values of primary branches per plant, pods length, days to maturity and 100 seed weight.

Background: Fenugreek is grown under various agro-climatic conditions of the world as well as in India. However, overall yield and quality depends upon various quantitative characters that exist during crop growth period. Therefore, this study aimed to find out the character association and path coefficient analysis among the seed yield and yield contributing characters in fenugreek genotype. Methods: Thirty genotypes were sown with three replications under two environments namely normal (E1) and limited (E2) irrigation conditions during Rabi season 2019-20. The experiment was laid down in RBD. Result: The genotypic and phenotypic correlations were exhibited significantly positive for number of pods per plant (0.765, 0.725 and 0.670, 0.651), number of seeds per pod (0.705, 0.650 and 0.666, 0.640) and pod length (0.376, 0.348 and 0.351, 0.327) with seed yield per plant in both the environments i.e. E1 and E2. The highest direct effect on seed yield per plant was observed for number o...

Present work studies of Yamuna river water quality at Agra. Rivers water is important role in ecological balance. Yamuna river is the second largest tributary of the river Ganga. Its water flows from Yamuna Nagar, Panipat, Sonipat, Delhi, Gautam Buddha Nagar, Faridabad, Palwal, Aligarh, Mathura, Agra, Etawah and Prayagraj (Allahabad). Yamuna river water has highly polluted at Agra. The reasons are being urbanization, industrialization and agriculture waste and fertilizers.So,water samples collection have been done on the basis of survey and taking samples on the different intervals at Hathi Ghat near railway bridge, Agra. These parameters were applied to pH ( 7.6 to 7.95), temperature ( 28 C to 35.5 C), electrical conductivity ( 1680 μS/cm to 1762 μS/cm), dissolved oxygen ( 4.5 mg/L to 4.8 mg/L), turbidity (15 NTU to 25 NTU ), total dissolved solid ( 1300 mg/L to 1550 mg/L ), salinity (0.48 ppt to 0.56 ppt ), chloride ( 270 mg/L to 310 mg/L), acidity ( 11.84 mg/L to 22.28 mg/L), tot...

The present work has been conducted on the effect of different concentration of sodium chloride (Nacl) ranging from 100 ppm to 500 ppm at three different time duration (6, 12 and 24 hr) in two different Broad Bean (Viciafaba) varieties.The maximum germination percentage has observed at 100 ppm at 6 hr seed soaking beyond this level germination has reduced gradually, in the same way time diffraction and concentration has also reduced gradually and 6 hr duration has shown maximum germination in both. The shoot length, root length and total length also increase upto 100 ppm in 6 hr when it is in NaCl and there after it gradually reduced. Mitotic index percentage was observed highest at 100 ppm and less disturbed, sticky and breakage of chromosome in both varieties.

Cowpea is grown for dry seed as pulse in the northern drier tracts while some forms of cowpea are also grown as fodder crops in the semi-arid western regions and in the humid tropic regions and large grown for vegetable purpose. It is a great important crop in arid and semi-arid regions of India because of its short duration, high yield potential and quick growing habits along with high protein content. Cowpea young leaves, pods and beans contain vitamins and minerals which have fuelled its usage for human consumption and animal feeding (Nielson et al., 1997).

A study was conducted at Agricultural Research Farm, R.B.S. College, Bichpuri, Agra (U.P.) during Rabi season 2007-08. Range, CV, genotypic, phenotypic and environment variance, genotypic and phenotypic co-efficient of variation, heritability, genetic advance, correlation co-efficient and path analysis were performed for yield and its contributing characters in 27 wheat genotypes. Analysis of variance for significant differences was among the all characters except, number of effective tillers per plant and spike length. A broad range of variation was observed for grain yield per ha-1, plant height at maturity and number of grain per spike. Phenotypic variance value for most characters was closer than the corresponding genotypic variance value showing little environment effect on the expression of these characters. The estimated value of broad sense heritability was found between 50.10 per cent (Spike length) and 97.20 per cent (grain yield ha -1 ). Heritability values were determine...

Remnant variability, heritability and genetic advance were studied in 90 half-sib progenies and unselected bulk material generated from “Raj Bajra Chari-2” of fodder Bajra [Pennisetum glaucum (L.) R. Br.] in Randomized Block Design with three replications along with unselected bulk material during kharif 2011 and data were recorded on days to heading (Plot mean basis) and plant height, tillers per plant, leaves per plant, stem thickness, leaf : stem ratio, leaf area, green fodder yield per plant (individual plant basis). The analysis of Variance of combined evaluation of half-sib and unselected bulk material as‘t-test’ (two sample assuming on equal variance) was non-significant for five character out of eight characters. “t-test” indicated non-significant differences between the half-sib and unselected bulk for days to heading, plant height, tillers per plant, leaves per plant and green fodder yield per plant while significant ‘t’ value was observed for stem thickness, leaf : stem r...
