Abstract Potatoes were planted 20 May at the University of Minnesota Agricultural Experi-ment Station, Rosemount, MN. Plots consisted of a single treatment row 30 feet in length with 10 feet of untreated potatoes between plots within rows. Plant spacing was 36 inches between rows and 12 inches between plants within rows. Treatments were arranged in a completely randomized design with 4 replications. Treated rows were separated by one row of untreated potatoes. Admire 2F was applied over the top of the potato pieces just before the furrows were covered. Foliar applications were made on 15 Jul with a CO2-pressurized sprayer fitted with a Teejet 8003-E flat-fan nozzle delivering 40 gpa at 35 psi. CPB population densities were determined by counting larvae on every plant in each plot on 16 Jul. In evaluating the treatments, direct counts of early instars (first and second) or late instars (third and fourth) were recorded. Analyses of variance was performed on data after log10(x +1) transformation.

Abstract This trial was located in a non-irrigated commercial potato field near Hollandale in southern Minnesota. Plots consisted of a single treatment row 25 ft in length bordered on each side by two untreated guard rows. Plant spacing was 36 inches between rows and 12 inches between plants within rows. Treatments were replicated four times in a completely randomized design. Treatments were applied with a CO2-pressurized backpack sprayer fitted with a single Teejet 8003-E flat-fan nozzle delivering 40 gpa/acre at 35 psi. All treatments were applied on 2 Jul. Spraying conditions were windy, but winds were constant. In evaluating the treatments, direct counts of early instars (first and second) and late instars (third and fourth) were made on every plant in each plot on 3 Jul. The data were subjected to analyses of variance following log10(x +1) transformation.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Abstract ‘Kennebec’ potatoes were planted in 20 foot rows on 25 Apr, ‘94. Plots consisted of a single treatment row. The distance between rows was 64 inches and the distance between plants within the row was 10 inches. Plots were arranged in a randomized complete block design with 4 replications. The soil was a Norfolk "A" loamy sand. Initial furrow treatments were applied to the seed at the rate of 20 gal per acre with a small watering can. Admire foliar treatments were applied at a rate of 50 gal per acre on 8, 23 and 29 Jun with a custom built compressed air row crop sprayer with each row being covered by 6 drop nozzles delivering 50 gal/acre at 30 psi. In evaluating the treatments, direct counts of the number of Colorado potato beetle adults, larvae and egg masses/10 plants and the % defoliation were recorded. Defoliation categories were assigned using a pretransformed defoliation rating scale, based on dividing 90° into 13 steps corresponding to arcsin transformation values (Little & Hills 1978). Yields were taken on 20 Jul from 20-ft of row.

A pot experiment was carried out at the Agronomy Teaching and Research Farm of the University of Agriculture Makurdi to determine the effect of manganese fertilizer on the growth and yield of rice. Treatment consists of five levels of Manganese (Mn) (0, 5, 10, 15 and 20 kg ha-1) in form of MnSO4. The treatments were laid out in a Completely Randomized Design (CRD) with three replications. The effect of Mn on the growth of rice indicate that there were no significant difference in the growth parameters measured with the exception of plant height at 8 weeks after planting and number of tillers at 4 weeks after planting. The tallest plants and highest number of tillers were obtained with 10 kg ha-1 Mn. The effect of Mn on the yield of rice indicate that there was a significant difference in the yield parameters measured with the exception of number of grain per panicle and root weight at 4 weeks after planting. Manganese at the rate of 10 kg ha-1 gave the highest grain yield (2,667 kg ha-1) and highest dry matter weight. Levels of Mn above 10 kg ha-1 led to yield decrease, therefore application of 10 kg ha-1 Mn was recommended for optimum yield of rice.

To determine the effect of Organic-based Fortified Foliar Fertilizer (OFF) on the growth and yield of ‘Lakatan’ banana, this study was conducted at the University of Southeastern Philippines, Tagum – Mabini Campus, Mabini Unit, Mampising, Mabini, Compostela Valley Province, from December 2015 to March 2016.          The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF. Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana. The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control. The fruit weight of T6 – RR of NPK+ OFF has 61% higher than untreated and the yield of 37 tons/ha is higher than the national average yield of 9.4 tons/ha in ‘Lakatan’ banana.

Aim: This research was designed to evaluate the effects of different levels of three mutagens on two pepper varieties with a vision of choosing mutants with high values in biochemical contents that may possibly be valuable in breeding improved varieties of the plant. Methods: Seeds of pepper were exposed to varying doses of gamma rays 60Co (50, 100, 150, and 200Gy), X-ray doses (40, 60, 80, and 100KV) and sodium azide (0.01, 0.02, 0.03 and 0.04%). The treated seeds and the controls were grown in the Botanic Garden of the University of Nigeria, Nsukka using a Completely Randomized Design. Results: The result showed that vitamin C and β-carotene ranged from 5.89 – 26.88 and 2.62 – 11.35 mg/100 g, Fe and Ca (14.70 and 13.78 mg/100 g) were highest in Shombo at 100Gy. Values ranging from 0.36-2.00 and 3.96 – 18.82 mg/100 g were recorded for flavonoid and alkaloid content across all treatment combinations. The result also revealed that at 100Kv and 150Gy, ash content increased in both varieties. The highest protein concentration of 9.57% was recorded at 100Kv of X-ray in Shombo and 6.96% at 150Gy of gamma irradiation in Tatase variety. Principal component analysis explained extracted five principal axis which accounted for the variability of 72.54%. Conclusion: This study reveals that biochemical content in pepper could be improved with exposure to mutagens especially gamma irradiation.

ABSTRACT Vegetable waste can be an alternative in the supply of animal feed because it has a relatively good nutritional content but the condition is easy to rot, so needs processing through technology in the form of wafers to optimize the utilization of vegetable waste. This study aims to determine the effect of different storage times on fiber fractions and is expected to provide information on how to make wafer feed for ruminant.This research was conducted in April to June 2019 at the Laboratory of Agriculture at the University of Muhammadiyah Bengkulu and continued by Van Soest analysts at the Bogor Institute of Agriculture Laboratory (IPB). The method used in this study is a Completely Randomized Design with A (control), B (stored for 1 week), C (stored for 2 weeks), D (stored for 3 weeks). The parameters observed were hemicellulose, cellulose, and lignin.The results showed that the treatment was significantly different for the content of hemicellulose and lignin but not significantly for the cellulose content. The conclusion in this study is that the storage time of wafers for 21 days can reduce the content of hemicellulose and lignin, but can not reduce the content of cellulose. Keywords: Vegetable Waste, Wafers, Hemicellulose, Cellulose and Lignin.
