An experiment was conducted to assess the effect of corm size and varieties on corm/cormels production and vase life of gladiolus ( Gladious grandiflorus L.) under Chitwan condition. A Field experiment was conducted in a farmer’s field at Gunjanagar VDC, Chanauli, Chitawan during November 2008 to April 2009. The experiment consisted of 12 treatment combinations laid out in two factorial Randomized complete block design (RCBD) with three replications. Four sizes of corms viz. 2-3 cm, 3-4 cm, 4-5 cm and 5-6 cm and three varieties viz. American Beauty, Interpret and Yellow Summer Sunshine formed 12 treatment combinations. Laboratory experiment was conducted to determine the effect of corm size and varieties on the vase life of harvested cut spikes of gladiolus at ambient temperature at the central laboratory of the Institute of Agriculture and Animal Sciences (IAAS), Rampur, Chitwan, Nepal. Corm size and varieties significantly affected corm/cormels production and vase life of gladiolus. Large sized corms (5-6 cm) performed better with respect to number of daughter corms and cormels per plant. Similarly, large sized corms (5-6 cm) showed better performance with respect to postharvest behavior such as total number of florets opened/spike (11.40), days to first and 100% floret withering as compared to small sized (2-3 cm) corms. Significant variation among three varieties was observed in most of the characters. Numbers of daughter corms were found highest in Yellow Summer Sunshine while maximum numbers of cormels/plant were found in Interpret. Similarly, Interpret proved best having more number of florets opened per spike and more days needed to first and 100% floret withering.DOI: http://dx.doi.org/10.3126/njst.v12i0.6477 Nepal Journal of Science and Technology 12 (2011) 35-40

African eggplant is an important fruit and leafy vegetable in Africa. Heterosis over mid and better parents was estimated in eight crosses of eggplant involving eight pure lines in a field experiment in 2012 and 2013 cropping seasons. The experiment was laid out using a randomized complete block design with three replications. Collected data was subjected to analysis of variance and significant differences were further subjected to Duncan Multiple Range Test. The aim of this study was to identify superior hybrids that can be advanced in the eggplant breeding program for improved yield and related traits. Significant variation was observed among all traits measured for the parents and hybrids. The highest fruit number was observed in NHS10-40 and in NHS 10-71 x NHS 10-40 among the parents and hybrids respectively. The highest heterosis was recorded in the cross between NHS10-71 x NHS10-40.

Diseases pose serious constraints to Sesame production in producing areas. Cercospora leaf spot (Cercospora sesami Zimm) has been identified as one of the most prevalent diseases which is to be controlled by Mancob M fungicide. The field experiment was carried out using a Randomized Complete Block Design and was replicated three times on a plot size of 4m x 5m with four sesame varieties and three Mancob-M fungicide levels (0, 2 and 4g) to give a total of twelve treatments. The laboratory experiment involved isolation of the pathogens from diseased leaves with symptoms of Cercospora leaf spot which was identified as Cercospora sesami. Data collected includes growth and disease parameters. The result revealed that 4g Mancob M recorded the lowest mean value for disease incidence and severity at 8WAS which was 90.30% and 35.60% respectively, while the control (0g) recorded the highest mean value for disease incidence and severity at 90.30% and 59.80% respectively. Ex-sudan recorded the lowest value of 720 kg/ha while NCRIBEN 03 recorded the highest yield of 834 kg/ha-1. For the concentrations, 2g recorded a higher yield of 843 kg/ha-1 followed by 0g which recorded 765 kg/ha-1. Variety E8 has a higher resistance to the disease while NCRIBEN 03 tends to be more susceptible but gave a higher yield. It therefore implies that variety E8 which showed higher resistance to the disease can be merged with NCRIBEN 03 (through hybridization) to produce a much better variety.

A field experiment is conducted to study the effect of different levels of peat (0, 25, 50, 75, and 100 Mg ha-1 to uncropped and cropped soil to wheat. Soil samples are taken in different period of time (0, 3, 30, 60, 90, 120, and 180 days after cultivation to determine (NaHCO3-Exteractable P at 3 different depths (0-10, 10-20, and 20-30 cm). Field Experiment is conducted in a randomized complete block design (RCBD) with four replicates. Wheat, Al-Rasheed variety, is cultivated as a testing crop. The entire field is equally dived in two divisions. One of the two divisions is cultivated to wheat and the second is left uncropped. The effect of five levels of peat namely 0, 25, 50, 75, 100 Mg ha-1 is investigated. Soils are fully analyzed to determine its physical and chemical characteristics. The soil samples are collected after 3, 30, 60, 90, 120, and 180 days for determining essential parameters and indicators that reflect the effect of the level of peat applications. Sodium bicarbonate - extractable P in uncropped and cropped soils at all depths, markedly decreases with time after peat application which has been attributed to plant uptake and rapid reaction of P with soil constituents. Sodium bicarbonate - extractable P with time in soil receiving 50 Mg ha-1 in both uncropped and cropped soil linearly decreases with the time of cultivation

Soybean (Glycine max L. Meril) is one of the most important and well recognized oil seed and grain legume crops of the world. A field experiment was conducted to investigate the efficacy of BAU-Biofungicide (Trichoderma harzianum), Trichoderma based IPM Lab bio-pesticide and Bavistin against anthracnose of soybean. Five soybean cultivars viz. Sohag, BARI Soybean-6, BINA Soybean-1, BINA Soybean-2 and BINA Soybean-3 were used in this experiment. The field experiment was carried out following Randomized Complete Block Design in the field laboratory of the Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh. Anthracnose infections were found initially lower at 80 DAS, moderate infections were found at 95 DAS and the highest infections were recorded at 110 DAS in case of all the tested five soybean varieties. The highest percent reduction of anthracnose infected plants/plot over control was observed in Bavistin treated plot (76.25%) that was near to BAU Biofungicide treated plots. All the growth parameters of soybean plants such as plant height, number of pods/plant, seed weight/plant, yield/plot and yield/ha were increased significantly in BAU-Biofungicide treated plots that showed best performance in compare to IPM Lab bio-pesticide (2%) and Bavistin @ 0.2% when these treatments were applied two times with 15 days interval. However, anthracnose incidence was reduced significantly when all the treatments applied in this experiment and the effect of BAU-Biofungicide was found almost similar to Bavistin in reduction of anthracnose of soybean.Res.

A field experiment was conducted at Bangaun, Lamahi-3, Dang, Nepal to study the effect of GA3 on growth and flowering attributes of African marigold (Tagetes erecta) in Inner Terai of Nepal. The experiment consists of three replications and 8 treatments and laid out in a randomized complete block design- consisting of various concentrations of GA3 viz. 0ppm, 50ppm, 100ppm, 150ppm, 200ppm, 250ppm, 300ppm, and 350ppm. Kolkata local variety of African marigold was tested. The study revealed that among different concentrations of GA3, 300ppm showed the tallest plant height (72.93cm) and the highest basal diameter (1.49cm). Maximum numbers of primary branches (3.11) and the greatest plant spread (32.11cm) were obtained from 250ppm; similarly, maximum numbers of secondary branches (13.80) were recorded in 350ppm. In the case of floral parameters both 100ppm and 350ppm recorded earlier days to 50% flowering (44.00 days each), days for 100% flowering was recorded almost similar in every treatment that sticks around 54 and 55 days, maximum diameter (5.370cm) of flowers were obtained from 50ppm, the greatest fresh weight (6.180g) was recorded in 350ppm, 250ppm showed a maximum number of flower per plant (104.13), similarly, a longer duration of flowering (58 days) was recorded in 300ppm. Among all treatments, the 250ppm level of GA3 was found to be most suitable in terms of production perspective.

Abstract: A field experiment was conducted at Jimtilo village along Maiduguri Jos/Kano road geographically located latitude 11o 501 5811North12o 561 2311 East above sea level. The experiment was conducted to determine the effect of Zai (pit planting) and different manure rate on growth and yield of sorghum. Randomized Complete Block Design (RCBD) replicated 3 times and consisted of 4 levels of treatments of 0, 1 ton/ha, 2ton/ha and 3ton/ha of manure (cowdung). The result of the experiment indicated that there was significant (p< 0.05) difference among and between treatments used. It was further observed that 3ton/ha manure applied gave significantly (p< 0.05) higher yield and performed better than all other treatments. The control however,gave the least value as all other treatments performed better than the control. It is therefore recommended that the application of 3 ton/ha should be adopted by farmers practicing pit planting or reclaiming arid land for sustainable agricultural production.

The research work on the evaluation of yard long bean genotypes for resistance to legume pod borer, Maruca vitrata F. was carried out in two consecutive seasons viz., kharif 2015 and rabi 2015-16 in randomized complete block design (RCBD) in the field of the Department of Entomology, Bangladesh Agricultural University (BAU), Mymensingh and chemical analysis of sugar, protein and phenol of yard long bean were carried out at Bangladesh Institute of Nuclear Agriculture (BINA), Professor Mohammad Hossain Central Laboratory and laboratory of the Department of Biochemistry and Molecularbiology, Bangladesh Agricultural University (BAU), Mymensingh. Nine genotypes of yard long bean were evaluated and reacted distinctly to M. vitrata with significantly different levels of infestation to flowers, pods and yield. The genotype Long Red Mollika was categorized as moderately resistant to legume pod borer in both kharif and rabi seasons. Genotype YL 305 was found susceptible in both the seasons. The plant attributes, both vegetative and reproductive, of yard long bean did not show any significant correlation in favour of resistance to M. vitrata. Yard long bean genotypes also did not show resistant reaction to M. vitrata in respect of sugar and phenol but particularly protein showed antibiosis against M. vitrata. J. Bangladesh Agril.

<p>Field experiment was conducted during the rainy seasons of 2011 and 2012 at the Teaching and Research Farm of the Faculty of Agriculture, Nasarawa State University, Keffi-Lafia Campus to study the competitive behaviour of groundnut in Sesame-groundnut intercropping system. The experiment consisted of four rates of poultry manure (0, 3.0, 6.0 and 9 t ha<sup>-1</sup>) and two planting arrangement (single alternate row and double alternate row planting arrangement). The eight treatment combinations were laid out in a randomized complete block design with four replications. The results obtained in both the years showed that sesame when grown with groundnut under different rates of poultry manure and planting arrangement appeared to be a dominant crop as indicated by its higher values of Land equivalent ratio, competitive ratio, higher and positive values for aggressivity and area time equivalent ratio. Application of 6 t ha<sup>-1</sup> of poultry manure and double alternate row planting arrangement produced the highest values for all the competition indices measured respectively.</p>
