The experiment was carried out from 16th December 2016 to May 10, 2017, in the horticulture farm of Nepal Polytechnic Institute Bharatpur-11. Cucumbers were planted under plastic house conditions (23.90 ± 3.55 ?C temp. and 59.15 ± 10.33% RH). Parthenocarpic cucumber variety Poyraz F1 was selected for the research. Fruits are harvested at four different maturity stages (Maturity stage 1, 2, 3, and 4) were treatments i.e. M1 – Immature stage 1 (harvesting of fruits after 2 weeks of fruit set), M2 – Immature stage 2 (harvesting of fruit after 3 weeks of fruit set), M3 – Mature stage (harvesting fruits after 4 weeks of fruit set) and M4 – Over-mature stage (harvesting fruits after 5 weeks of fruit set). Each treatment was replicated 5 times with 5 plants in each experimental unit and these experimental units were arranged in a completely randomized design. There was a significant difference among the selected treatments in the number of flowers per plant at 30, 45 & 60 DAT, the number of internodes per plant at 45 & 60 DAT, numbers of fruits per plant at 30, 45 & 60 DAT and number of harvest per plant. The total yield per plant was observed as not significant. Highest no. of flowers (6.88, 15.52 and 5.83 at 30, 45, and 60 DAT), nodes (5.44, 6.76, 10.53 and 15.53 at 15, 30, 45 and 60 DAT) and fruits (1.4, 5.6, 15 and 25.2 at 15, 30, 45 and 60 DAT) per plant were recorded in the plant in which fruits were harvested at immature stage 1 (harvesting fruits at 2 weeks of fruit set) whereas their values were minimum in the plants in which fruits were harvested at over-mature stage (harvesting fruits at 5 weeks of fruit set). A maximum number of harvests (6.40) were recorded in the plants in which fruits were harvested at an earlier maturity stage. Yield per plant did not vary significantly. Hence, it would be better to harvest cucumbers at an immature stage as the fruit harvested at an earlier stage of maturity had more number of harvests and the producer could enjoy the diffe

Abstract Number of pigs born alive has been a key factor of the increasing efficiency of the U.S. swine industry. However, with increased pigs in the uterus, birth weight has been negatively impacted, with more small or at-risk pigs being born per litter. In order to overcome these changes, a study testing three commercial oral drenches against a control to determine which would increase average daily gain and decrease preweaning mortality. In a completely randomized design, 877 one-day-old suckling pigs from a high-health farm were selected for the experiment if they appeared to be in the bottom 20% of bodyweight compared to their contemporaries. Selected pigs were given one of four drenching treatments: 1) none (control), 2) bioactive proteins (BP), 3) high energy sugars (HES), and 4) immunoglobulins (IgY). Pigs were weighed on d 1 and d 19 of age (weaning), with mortality tracked during the suckling period. Data were analyzed using SAS v 9.4 (Cary, NC), with pig as the experimental unit and an accepted alpha of 0.05. Treatment had no detected effect on birth weight, weaning weight, ADG, or mortality (P = 0.79, 0.96, 0.86, 0.38 respectively). Likewise, statistical contrasts were used to determine there was no detected impact (P > 0.10) of drench, regardless of type, compared to the control in any measured response criteria. Interesting, pigs drenched with BP or IgY had numerically lower preweaning mortality (11.2 and 11.5% respectively), than those administered the control or HES (15.4 and 15.2%, respectively). In conclusion, this experiment showed no significant difference in the performance between piglets given no product vs. those drenched with bioactive proteins, high energy sugars, or immunoglobulins. However, additional research is warranted with greater replication or disease stressors to better understand if oral drenches may improve preweaning performance or mortality in different situations.

Curcuma sp has been widely investigated for its anti-cancer properties. Conventionally, vegetative propagation needs a long time to produce a large number of planting materials, so that it is necessary to find an alternative approach through in vitro propagation.  The effect of BAP on the in vitro shoot formation of ‘temu putih’ and ‘temu putih’ has been investigated in this study. The experiment was a 4x2 factorial with 5 replications arranged in a completely randomized design.  The first factor was the concentration of BAP i.e. 0, 1.5, 3, and 4.5 ppm.  The second factor was the curcuma species consisting of ‘temu putih’ (Curcuma zedoaria Roch.) and ‘temu mangga’ (Curcuma mangga Val.).  Each experimental unit consisted of 2 in vitro bottles, each of which planted with 1 explant bud.  Analysis of variance was conducted on percentage of live explants, shoot height, number of roots, root length, wet weight, percentage of explants that sprouted, percentage of rooted explants and shoot color.  Mean comparison was performed by the Least Significant Difference (LSD).  The results showed that there was no interaction between BAP concentration and genotype on any variable observed.  The shoot growth of ‘temu putih’ was significantly higher than ‘temu mangga’ in vitro.  The best concentration of BAP for the growth of ‘temu putih’ and ‘temu mangga’ shoots was 1.5 ppm.

The utilization of an alternative enzyme for rennet substitution in cheese production offers promising potential for product diversification. In this research, the physicochemical characteristics and protein profile of cottage cheese made by using the crude extract of bromelain enzyme from Ananas comosus were evaluated. The observed variables include protein, fat, water, and ash content, as well as the cottage cheese yields, texture, meltability and protein profile. The research was conducted in a completely randomized design with 3 different bromelain concentrations at 1.5% (K1); 3% (K2); and 4.5% (K3) and each was replicated for 4 times. The obtained data were analyzed with analysis of variance (ANOVA) and followed with the Least Significant Difference (LSD) test to measure significant differences, while the protein profile of the cottage cheese was observed by using SDS-PAGE and analyzed descriptively. The different enzyme concentrations showed that the different bromelain concentrations had significant differences (P<0.01) to the overall physicochemical properties of the cottage cheese, with the protein content at 11.50 to 12.64%; fat content at 2.13 to 5.21%; water content at 56.01 to 57.65%; and ash content at 0.59 to 1.68%. The produced cottage cheese had yields at 8.46 to 10.62%; texture at 3.67 to 3.81 N; and meltability at 1.89 to 2.82%, while the protein profile observation showed different bands at 4.58 to 160.47 kDa. The research concludes that 3% bromelain concentration produces cottage cheese with the best physicochemical properties in this research, that contained 12.64±0.43% protein, 2.13±0.90% fat, 56.06±0.22% water, 0.59±0.38% ash, with cheese texture of 3.81±0.11 N and 282±0.13% meltability from a total yield of 10.62±0.06%.

The treatment of goat manure at a dose of 10tons/ha had been able to increase all parameters and goat manure with a dose of 30 tons/hagave high results on all parameters of cucumber plants compared to that of the control. Thetreatment of black silver plastic mulch with a goat manure dose of 30 tons/ha gave high resultsin the number of fruit parameters.


what is impact of regulated deficit irrigation and foliar Zn nanoparticles application on productivity of mango trees? the answer to this question represents the main objective of this study. To verify this, an experiment was performed during the 2016/2017 on the mango trees mango (Mangifera indica L.) cvs." Nawomy" and "Sokary" which have about 16 years old in sandy soil under drip irrigation system. 100, 50, 75% of the crop evapotranspiration "ETc" were used, in parallel with three levels of concentrations of NPs-Zn micronutrient (0, 50, and 100 ppm) were applied three times; i.e., before flowering, 10 days after full bloom and after fruit set stages in both seasons. The highest yield and water-use efficiency were obtained with applying the RDI-75% of ETc treatment without significant difference that 100% of ETc treatment. The average fruit weight and size, length and width were larger for mango fruits from the 100% of ETc and 75% of ETc, with TSS%, total reducing sugars and ascorbic acid content being significantly greater than fruits of other irrigation treatments. Therefore, using the nano zinc as foliar sprays on mango trees at a concentration of 100 ppm improved fruit set percentage, total yield fruit quality (physical and chemical properties), also increased water use efficiency. It could be concluded that irrigated trees with 75% of ETc plus foliar spraying of nano zinc (NPs-ZnSO4) at 100 ppm was the most effective treatment for increasing fruit set, total yield and quality as well as water use efficiency of Nawomy and Sokary mango trees.
