Evaluation of integrated agriculture aquaculture (IAA) was conducted on station in the National Fisheries and Aquatic Life Research center (NFALRC), Sebeta. In this trial the effect of irrigation with pond water and spring water and application of inorganic fertilizer on yield and other parameters for Tomato (Lycopersiconesculentum) and potato (Solanum tuberosum) were evaluated using randomized complete block design with three replications. Results show that there is variation in total yield and marketable yield as well as clusters per plant of tomato with plots treated with fertilizer having higher values. Among examined parameters, only clusters per plant of tomato varied significantly (P<0.05) among treatments. However, marketable yield and yield per plant did not show significant variation (p>0.05) among treatments. Nevertheless, all parameters in this trial did not show significant difference among treatments (P>0.05). The results of this trial indicate that using pond water to irrigate horticulture plots can partially replace the use of inorganic fertilizers thereby reducing both cost and environmental effects.

A field experiment was conducted at Horticulture Research Station (HRS), Dailekh, in Mid-Western hills of Nepal during 2019 and 2020, to evaluate the performance of ten potato genotypes for plant, and tuber yield characters. The potato genotypes were evaluated during spring season in a randomized complete block design with three replications. The genotypes showed highly significant difference for all the traits except tuber emergence. The mean squares for the year were also significant for all the traits except tuber emergence, stem numberplant -1 and total tuber yield. The interaction between genotypes and years did not show significant differences in all the traits except stem numberplant -1. Genotype CIP392797.22 produced more marketable yield (27.5 tha -1) and total tuber yield (30.2tha -1) than all other genotypes. The genotype CIP392797.22 is characterized as medium maturing, oval-shaped and dark red-skinned one with shallow eye depth in the tuber, and it imparted 13.2% higher marketable yield than Kufri Jyoti (24.3 tha -1). Thus, the genotype CIP392797.22 is recommended to evaluate on-farm for the verification and up-scaling among farmers at Mid-Western Nepal.

This experimental study was conducted to determine the effect of unilateral nephrectomy on kidney function through hematological and urological values after surgery using feral domestic cats.  Four (4) apparently healthy stray male cats were caught and used as experimental animals in this study. The animals were grouped into two (2) with two cats in each group. Grouping of the animals was based according to age, the 1st group – ages one year and above (>1 year) and the 2nd group – ages one year and below (<1 year).  A split plot randomized complete block design was used in the experiment. The result shows that rectal temperature and packed cell volume have been affected on both age group of cats and other urological values like the presence of urobilinogen, protein, leukocytes, erythrocytes and crystals were elevated twenty four hours after surgery. A significant increase on the level of creatinine and blood urea nitrogen has been noted from the 3rd and 15th post – operative day. However, no significant difference was noted between experimental animals and the two age groups, all of which have similar result. The findings of the study revealed that the remaining kidney could not completely compensate the function of the other kidney up to the 15th post – operative day, it may take longer than fifteen days. Hence, proper supportive treatment, post-operative care & management of animals subjected to unilateral nephrectomy is a must and should continue beyond fifteen days.

Field experiment was carried out during 2010 rainy season to find the effect of seeding rate on the growth and yield of okra (Abelmuschus esculentus) in Zuru Northern Guinea Savannah. Zuru is located in Zuru Local government area of Kebbi State (Latitude 11o 251 to 11o 551 North and Longitude 4o 51 to 5o 251 East of the equator). The experiment consisted of three treatments that is planting okra at one plant per stand (S1), two plants per stand (S2) and three plants per stand (S3). The experiment was laid out in randomized complete block design (RCBD) and the treatments replicated three time. The result of the experiment has shown that plant height and number of leaves/plant at 3, 6 and 9 weeks after planting (    WAP) were significantly influenced by seeding rate (P<0.05). At 3, 6 and 9 WAP tallest plants were obtained from okra plants planted at three plants/stand (27.83, 54.0 and 77.0cm) respectively followed by okra planted at two plant/stand (24.77, 50.67 and 74.33 leave/plant respectively ). However, more number of leaves/plant were obtained from okra plant at one plant/stand (9.67, 24.67 and 48.0 leaves/plant respectively) followed by okra planted at two plants/stand (8.33, 18.33 and 36.33 leaves/plant respectively). Seeding rate had significant influence on time of 50 percent flowering with one plant/stand first attaining 50 percent flowering stage just within 36.33 days followed by okra planted at two plants/stand (38 days). The mean fresh fruit yield of okra was also significantly influenced by seeding rate with the highest yield of fresh fruits obtained from three plants/stand (83.34/ha) followed by okra planted at two plants/stand (55.56/ha). However, the result of the findings recommends that, okra should be planted at two plants/stand for medium sized and marketable okra fresh fruits since at three plants/stand leads to the production of undersized fresh fruits which do not often attract customers. At one plant/stand, there seemed to be early fruiting and bigger sized fresh fruits but low total yield due to underutilization of land resource/space. Planting at one plant/stand should therefore be avoided

A field study was conducted at Tennessee State University's research station to evaluate the effect of hardwood bark mulch on the winter survival of garden mums. A randomized complete block design was used. Cultivars used were adorn, encore, grandchild, jackpot, legend, minnautumn, minnwhite and triump. At the end of the flowering season the tops were removed leaving a four inch stubble in the mulch. The number of mum plants that resumed growth the following spring were counted for each cultivar. There was a difference in the winter survival of the different cultivars as well as a significant difference in the mulch treated and the control. Grandchild and jackpot were most cold hardy followed by encore, minnwhite, minnautumn, triump, legend, and adorn. Grandchild and jackpot with four inches of hardwood bark mulch had an 88 percent survival while the control had a 44 percent survival. Adorn. had a 51 percent survival with four inches of mulch and a 20 percent survival in the control. This data shows that hardwood bark mulch holds a great potential for providing excellent winter protection for garden mums.

An experiment was conducted to assess the performance of sweet pepper varieties as influenced by nitrogen levels from August 2014 to February 2015 at Mangalpur, Chitwan. The experiment was laid out in two factorial Randomized Complete Block Design (RCBD) with three replications having sixteen treatments. Varieties and levels of nitrogen significantly affected growth, yield and qualitative parameters of fruits. Hybrid Indra and NS 632 performed better than open pollinated varieties viz. Sagar and California Wonder. Days to fifty percent flowering of NS 632 were earlier than California Wonder. Indra variety had the highest plant height (52.18 cm), number of secondary branches per plant (13.51) from 250 kg N/ha through chemical fertilizer while number of leaves per plant was higher in NS 632 variety (57.22) than Sagar variety (47.37). Indra variety showed the highest fruit weight (87.59 g) and total yield (39.45 t/ha) but NS 632 variety produced more number of fruits per plant (9.25) than California Wonder variety. This study showed that sweet pepper yield of hybrid varieties applied with 250 kg N/ha through chemical fertilizer was appropriate dose to get optimum yield under Chitwan condition.

Chipping Potato

The cost of seed accounts for nearly 10% of the estimated production cost of chipping potato (Solanum tuberosum) production in Florida. Optimizing seed piece spacing can reduce costs without affecting potato yield. This study evaluated the effects of seed piece spacing on yield, quality, and economic revenue of chipping potato production in north Florida. A field experiment was conduct during the spring of 2013, 2014, and 2016 in Hastings, FL, with a split-plot randomized complete block design. In-row seed piece spacings of 10, 15, 20 (industry standard), 25, and 30 cm were assigned as the main plot and S. tuberosum potato cultivars (Atlantic, Harley Blackwell, and Elkton) as the subplots. Marketable tuber yield ranged between 10.8 and 15.2 Mg·ha−1 in 2013, 10.1 and 12.8 Mg·ha−1 in 2014, and 9.9 and 19.7 Mg·ha−1 in 2016. Overall lower yields in 2013 were due to three freeze events early in the season. Widening seed piece spacing resulted in a linear decrease in total and marketable yield in 2013 and 2014. Conversely, seed piece spacings of 10 and 15 cm showed lower marketable yields in 2016. There was no interaction between in-row spacing and cultivar in any year tested. Cultivars performed variably across years for total and marketable yield and specific gravity. Tuber specific gravity was unaffected by seed piece spacing, except in 2013, when 25 and 30 cm resulted in slightly higher values. There was no significant difference in total and marketable yield between the industry standard seed piece spacing 20 and 25 cm in any year. In-row spacing of 25 cm in 2013 and 30 cm seed piece spacing in 2014 and 2016 provided the greatest economic return. Net revenue can be increased by adjusting the in-row seed piece spacing from the commercial standard of 20 to 25 cm, which reduces production cost without negatively impacting yields.

Abstract This study examined the effect of 1-monoglycerides and 1,2-diglycerides of butyric-, caproic- and caprylic acid (SILOHealth™ 104L [monoglycerides]) and avilamycin on day 14 and 21 post weaning performance of E. coli (GN-Ent and O157:H7) day 5 challenged piglets fed corn/soy diets that met or exceeded current NRC (2012) recommendations. A total of 96, Choice Genetics CG32, piglets were used in a randomized complete block design with pen as the experimental unit, treatment as the fixed effect, and block as the random effect (4 piglets/pen x 3 treatments x 8 replications). Pigs were blocked by sex and weight and were orally dosed with 5 ml (1x109 CFU/g, strain GN-Ent and O157:H7) E. coli d 5 after weaning (Ec). The treatment were: NC with Ec; T1=NC + 3 kg/MT monoglycerides; T2=NC+ 80 ppm avilamycin. Least significant difference was used to compare means of treatment. Mortalities and pen removals were weighed and recorded. The E. coli infection model was effective in causing E. coli mortality of 25% at d14 post weaning and 33% at d21 post weaning in NC. T1 and T2 reduced mortality versus NC at d14 (25, 3 and 0%, P < 0.05) and d21 (33, 4 and 0%, P < 0.05), increased ADG at d14 (203, 255 and 259 g, P < 0.05) and d21 (456, 511 and 515 g, P < 0.05), decreased FCR at d21 (1.90, 1.85 and 1.83, P < 0.05), and decreased intestinal E. coli, log 10 of CFU/g, versus NC (4.1, 2.2 and 2.1, P < 0.05). Monoglycerides and avilamycin performance, mortality and intestinal E. coli log 10 were not significantly different at P < 0.05. In conclusion, the use of monoglycerides improved ADG, reduced FCR, reduced mortality and reduced intestinal E. coli log 10 at day 14 and 21 post weaning versus NC and monoglycerides were not significant different (P < 0.05) than avilamycin.
