Hybrid Maize

In Nepal, the productivity of maize is very low in comparison with developed countries. The use of hybrid varieties with proper nutrient management helps to unlock the high yielding potential of maize. So, the experiment was conducted at Fulbari, Dang, Nepal from June 30, 2019 to October 16, 2019 to find the yield performance of two maize varieties (Local and Hybrid) under different nutrient management. The study was conducted in factorial randomized complete block design with three replications and eight treatments. Treatments consist of different combinations of two maize varieties (Local and hybrid) and four different nutrient management practices. Significant effects of Nutrient management were observed on plant height, l eaf area index (LAI), kernels per row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. Similarly, significant effects of varieties was observed on plant height, leaf number, LAI, cob length, kernel rows per cob, kernels per kernel row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. Interaction effect of Nutrient management and varieties was found significant on LAI, kernel rows per cob, kernels per kernel row, kernels per cob maize, test weight, biological yield, economic yield and harvest index of maize. The overall performance of hybrid maize under Leaf color chart (LCC) based nutrient management was found better than other treatments. Therefore, production of Hybrid maize under LCC based nutrient management is suggested. Int. J. Appl. Sci. Biotechnol. Vol 8(2): 191-198

Maize (Zea mays L.) is a significant food security crop in Kenya and it serves as the main source of nutrition and calories among the small-holder farmers. The overall maize yields per hectare have been fluctuating in the past few years posing a great risk to food security. Among the stress factors associated with maize yield loss include plant-feeding nematodes. In this regard, this study was conducted to evaluate the impacts of plant-parasitic nematodes specifically Scutellonema spp. under field conditions on maize performance in Mwea, Kenya. The field trials were laid out in a randomized complete block design with each treatment comprising of four replicates. The treatments included maize plots without nematicide (MPWN) and control plots treated with nematicide. The experiments were conducted in two trials. Soil samples were taken at a 0–20 cm depth at monthly intervals during 2018–2019. During the two trials, MPWN recorded significantly lower plant height and number of leaves per plant. Correlation analysis revealed a significant negative relationship between Scutellonema abundance with leaf area index, plant height, and number of functional leaves in MPWN during the 2019 trial. This implies that high population of Scutellonema perhaps has the potential to affect leaf area index, plant height, number of leaves per plant, which are aspects that in turn influence maize productivity. Therefore, holistic sustainable management practices to control Scutellonema spp. in maize fields such as use of organic amendments, resistant maize cultivars, and antagonistic organisms are crucial in order to alleviate negative impacts linked to Scutellonema infestation.

The Field experiment was conducted to evaluate the effect of fertility management on growth, yield attributes and yield of pearlmillet in a Randomized Block Design (RBD) with ten treatments and four replications during summer, 2019 at Anand, Gujarat. The experiment comprises of different nutrient management practices including 100% and 75% RDF with 15 t and 10 t FYM along with Bio NP consortia. A significant higher growth and yield parameters enhancement with the application of 100% RDF + 15 t FYM ha-1 + Bio NP Consortia was recorded in plant height, number of tillers, length of ear head, protein content and biological yield. The treatment T5 produced maximum (91.5 q ha-1) biological yield and statistically it was on par with T9 and T5. However, the lowest biomass production (73.0 q ha-1) was reported in treatment T1. Results of different nutrient management practices on days to 50% flowering, days to maturity, ear head girth and test weight were found non-significant.  Protein content of pearlmillet was increased from 7.5% to 9.06% under different nutrient management practices.

Context: Direct selection based on crop yields is often a paradox in breeding programmes because yield is a complex polygenically inherited character, influenced by its component traits.   Objectives: The present research work was taken up to assess genetic variability, phenotypic and genotypic associations between various components of grain yield to provide basis for selection and yield improvement in rice.   Materials and Methods: Correlation coefficient and path association are used to find out the degree (strength) and direction of relationship between two or more variable and for fixing up the characters which are having decisive role in influencing the yield. Therefore, a field experiment was carried out to establish the extent of association between yield and yield components and others characters in rice. Analysis of variance revealed that significant amount of genetic variability was present in the entire characters studied.   Results: High heritability coupled with high to moderate genetic advance as % of mean was observed on plant height seed yield per plant, biological yield, harvest index, test weight and number of spikelets per panicle suggesting preponderance of additive gene action in the expression of these characters. The correlation coefficient between seed yield per plant and other quantitative attributing to yield showed that grain yield was significantly and positively associated with harvest index, number of tillers per hill, number of panicle per plant, panicle length, number of spikelet's per panicle and test weight at both genotypic and phenotypic levels. Path coefficient at genotypic level revealed that harvest index, biological yield, number of tillers per hill, panicle length, number of spikelets per panicle, plant height and test weight had direct positive effect on seed yield per hill, indicating these are the main contributors to yield.Conclusion: From the correlation and path study it may be concluded that harvest index, number of tillers per hill, panicle length, and number of spikelet per panicle and test weight are the most important characters that contributed directly to seed yield per hill. Thus a genotype with higher magnitude of these traits could be either selected from existing genotypes or evolved by breeding program for genetic improvement of yield in rice.   Key words: Rice; variability; heritability; agro-morphological traits; correlation; pathDOI: http://dx.doi.org/10.3329/jbs.v18i0.8767 JBS 2010; 18(0): 1-8

The present study was conducted at the Research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during March to June 2014 to examine the effect of Phosphorus on the growth and yield of Sesame. BARI Til-3 variety was used for the study. This experiment was consisted of single factor eg. phosphorus. There were three levels of phosphorus viz. (i) P0 (0 % P), (ii) P1 (20 % P) and (iii) P2 (30 % P) and the experiment was laid out in a Randomized Complete Block Design (RCBD) with six replications. Different levels of phosphorus showed significant effect on growth and yield of sesame. Individually phosphorus had significant effect on highest plant height, number of leaves plant-1, number of primary branches plant-1, number of secondary branches plant-1, number of capsule plant-1, number of seeds capsule-1, 1000 seed weight, seed yield and harvest index. The highest plant height of sesame (136.30 cm), the highest no leaves plant-1 of sesame (34.44), number of primary branches plant-1 (5.56), number of secondary branches plant-1 (7.61), number of capsule plant-1 (25.87), number of seed capsule-1 (70.47),1000 seed weight (3.54), Seed yield (1581.00 kg ha-1), Stover yield (3034.42 kg ha-1), biological yield (4615.76), harvest index (34.11%), oil content (43.92%) was recorded from P1. Again, the highest days to first flowering of sesame (31.67) was recorded from P1 (20 % P) but the highest days to maturity was (85.67) recorded from P2 (30% P). Application of P at different percentage is causing effect in growth and yield of sesame. Res. Agric., Livest. Fish.6(2): 245-251, August 2019

A field experiment was conducted on farmer’s field at two sites of Lamjung district of Nepal viz. Bhotewodar and Sundarbazaar to evaluate the performance of two commonly grown rice varieties viz US-382(hybrid) and Ramdhan (improved) under two nutrient management practices [Nutrient Expert®(NE) rice model recommendation, and government recommendation(GR)].Four replicates of four treatments were arranged in randomized completely block design. Rice varieties responded differently under the different nutrient management practices in terms of plant height, grains per panicle, sterility%, panicle weight, grain yield at 15% moisture, straw yield and harvesting index. The highest grain yield was obtained from NE field of US-382 variety which was followed by GR for US-382, NE for Ramdhan and GR for Ramdhan variety. NE based practices for US-382 variety produced higher biological yield as compared to GR. NE estimated attainable rice yield provided by the software compared with actual rice yield from the trials in farmer’s field and NE-based fertilizer recommendations proved the validity in reaching the yield targets estimated by the software. The observed rice yields recorded in the trials were higher than the NE estimated attainable yields, so NE recommendation for US-382 variety was found better over GR.Int J Appl Sci Biotechnol, Vol 4(2): 223-227

Context: Genetic diversity is pre-requisite for any crop improvement programme as it helps in the development of superior recombinants. Objectives: Recognizing the importance of genetic diversity in plant breeding experiments, the present research work was taken up to estimate genetic diversity in different accessions of rice for various agro-economically important characters. Materials and Methods: Experiments were carried out with 40 Rice (Oryza sativa L.) genotypes which were evaluated for yield and yield contributing traits in Kharif-2007-08. The data were recorded on 10 randomly selected plants from each replication for 12 quantitative characters studied. However days to 50% flowering was recorded on per plot basis. Mean values were subjected to analysis of variance to test the significance for each character. The genetic divergence was estimated and the grouping of the genotypes into cluster was done.Results: Sufficient amount of variability was found in the entire gene pool for all traits studied. The higher magnitude of genotypic and phenotypic coefficients of variation was recorded for plant height, grain yield per hill, harvest index and biological yield per hill. High heritability along with high genetic advance as percent of mean was registered for harvest index, grain yield, plant height, biological yield, test weight, number of tillers per hill and number of spikelets per panicle suggesting preponderance of additive gene action in the expression of these characters. On the basis of Mahalanobis D2 statistics the genotypes were grouped into seven clusters. Plant height, biological yield and test weight contributed considerably, accounting for 86.16 % of total divergence. The genotypes superior in some clusters may be involve in a multiple crossing programme to recover transgressive segregants with high genetic yield potential and early maturity. Conclusion: The promising genotypes selected from diverse clusters should be involved in the hybridization programme in order to transfer some of the desirable yield contributing characters consisted by them.  Key words: Rice (Oryza sativa); genetic variability; diversity; clustering pattern DOI: 10.3329/jbs.v17i0.7110J. bio-sci. 17: 77-82, 2009

Soybean, an important legume crop, serves as a good source of protein and oil with tremendous ability to fix atmospheric nitrogen for soil improvement. To study the genetic variability, genotypic, phenotypic and environmental coefficient of variation, broad sense heritability and genetic advance in soybean, a field experiment was conducted during Kharif 2013. The experiment, laid out in a randomized block design (RBD) with three replications, comprised of 24 genotypes and observations on 9 traits of soybean were recorded. In this experiment, analysis of variance indicated that significant variation were present among the different genotypes of the soybean for all the traits under study. The highest genotypic (GCV) and phonotypic coefficient of variation (PCV) were exhibited by the test weight, number of pods per plant, harvest index and plant height. The PCV was found higher than GCV which indicates the important role of environment in the expression of the characters. High heritability and high genetic advance were observed in the test weight, number of pods per plant, harvest index and plant height. The combination of the high heritability and high genetic advance provide the clear image of the trait in the selection process for crop improvement programme.

Oat (Avena sativa L.) is used as a green fodder, straw, hay or silage. A field experiment was carried out during 2008-2009 with the concept of integrated nutrient management at Aurawan Research Centre of CSIR-National Botanical Research Institute, Lucknow. The treatments of the experiments were T1- Control, T2- NPK (80:40:40 kg ha-1), T3- ½ NPK (40:20:20 kg ha-1) + FYM (10 t ha-1), T4- ½ NPK + FYM (10 t ha-1) + Trichoderma, T5- ½ NPK + FYM (10 t ha-1) + PSB and T6- ½ NPK + FYM (10 t ha-1) + Trichoderma + PSB with 4 replications in randomized block design (RBD). Results indicated that all the treatment showed significant response over control. Maximum plant height at 120 days (157.7 cm), tillersplant-1 at 90 days (6.4), length of spike (38.7 cm), test weight (28.6 g), grain yield (34.9 q ha-1), straw yield (82.8 q ha-1) were recorded with T2- NPK (80:40:40 kg ha-1) which was significantly higher than all the treatments except T3- ½ NPK (40:20:20 kg ha-1) + FYM (10 t ha-1) and T4- ½ NPK + FYM (10 t ha-1) + Trichoderma, followed by treatment T6- ½ NPK + FYM (10 t ha-1) + Trichoderma + PSB showing the value of plant height at 120 days (154.8 cm), tillers/plant at 90 days (6.3), length of spike (37.6 cm), test weight (28.3 g), grain yield (33.1 q ha-1) and straw yield (81.1 q ha-1). Seed treatment with PSB (T5) also responded significantly over control in all the parameters and remained at par with T2 and T6. However, combined seed treatment with PSB + Trichoderma (T6) was much effective in comparison to single inoculation of Trichoderma or PSB.
