4 Sample Horticulture Produce Math Problems 1. Your anticipated Jalapeno yield is 10 tons per acre. Assuming you will have a 2 % harvest/processing loss how many pounds of jalapenos would be marketed from a 3.5 acre farm? 2. Rhubarb crowns are planted at 2.5 feet intervals. How many crowns would you need for one garden row that is 96 feet long? 3.Beets require.21 inches of water per day. How many inches of water would be needed for the month of July? 4. Joe Greenhand harvested 1200 pounds of watermelons for the farmers market. A watermelon is 92 % water. How many pounds of plant product is Joe actually transporting? 5. If there are 3,000 radish seeds to an ounce. How many seeds would be found in one pound? 6. Crucifer crops require ph above 6.8. You need to raise the ph of your 50 acre field. How many pounds of hydrated lime need to be applied. ( application rate is 1500 lbs. per acre) 7. Commercial peas are grown at a rate of 400,000 plants per acre. How many plants could be grown on 4.25 acres? 8.Your 1 acre tomato patch requires 1.5 lbs. of seed. There are 9,000 seeds to the ounce. Assuming a 90 % germination rate, how many plants can you expect. 9. Baby corn will yield 8,000 unhusked pounds per acre. Ninety percent of the weight is husks, silk etc., that will be removed. How many pounds of husked marketable product remain?

5 PRODUCE JUDGING STANDARDS Judging is a matter of opinion should be on certain facts and standards. The standards of excellence should be adhered to in judging: it will lower the quality of products at a show or in the market. In judging fruits and vegetables for show, remember three main parts: 1. Uniformity of size 2. Uniformity of shape 3. Uniformity of color Size - Choose exhibits that are all the same size; they should be medium in size and not too Shape - Choose exhibits having the same shape and being typical for the variety. Color: The specimens should have the same color or color markings, i.e., peaches with a The materials to be judged should be: 1. True to type 2. Of good quality 3. In good condition - free of bruises, cuts, discoloration, etc. 4. At proper stage of maturity for eating 5. An example of cultural perfection 6. Free from pest damage 7. Clean Special Points to Consider in Selecting and Judging Vegetables: Beans, green and wax Fresh color Uniform in length coloring and maturity Good shape for variety - generally straight but some varieties curve on Pod brittle, not wilted Fleshy and well filled with pulp from one end to other, but without beans being prominent Beans one-half mature Free from defects Can be shown with or without stems, but should be uniform Leave stems attached to pod Tough Wilted Pale and discolored Evidence of insect and disease Knife marks on the pod

6 Beets Broccoli Cabbage Carrots Uniform in size, color and shape Size from one and one-half to three and one-half inches in diameter Generally dark red with little russeting on crowns No cracks, new varieties including gold colored beet Cut off tops to approximately one inch Color not within uniform, light streaks visible, damaged, cracked, pithy, wilted, too large and tough for eating Fresh green color Right stage of maturity for eating Flowers tightly budded without yellow showing, crisp Free from worms and aphids Stems should be under six inches long A few lower leaves may be trimmed off leaving no stubs Small, loosely closed sprouts; yellowish color, wilted Heads solid and firm; salad types 5-8 inches in diameter Kraut types -8 inches in diameter Tender, crisp good weight for size Free from insect damage or disease Type is important as varieties differ in shape Shape may include: round, flat, pointed, red and savoy Outer leaves should be removed, leaving only the last few that curl at the tips (wrapper leaves) Cut stem one-fourth inch below lowest leaf Poor color, loosely formed, wilted Disease or insect damage Incorrect size or shape Type very important: Short (3-4"); Half Long (5-7"), and Long (8" and Diameter depending on variety Smooth, straight Pale to deep orange, depending on variety; each carrot same size and Cut tops off at approximately one inch Off-colored, wilted, rough, cracked, insect damage, crooked or branched

7 Cauliflower Preparation Cucumbers Eggplant Herbs Kohlrabi Solid heads, good white color Smooth fine grained texture Crisp Outer leaves trimmed evenly about one to two inches above center of head. Cut stem one-fourth inch below lowest leaf. Wilted Yellow to brown color Rough, grainy texture (ricey) (Listed under various classifications): Picking - one to three inches long; Slicing - six to eight inches long; and Gherkins (West India) - small pickling cucumbers that have burr-like fruit two to three inches long, one to one and one-half inches thick. Bright green skin with fleshy prickles. Should be even in size, crisp Leave one-fourth to one-half inch of stem attached Light in color Not uniform in color and size Over mature Misshapen fruit Symmetrical and true to type 3-5 inches in diameter Firm, mature and uniform in color Stems trimmed one to one and one-half inches Do not wash, but wipe with a damp cloth Wilted, misshapen Poor color, streaks in color of either green or white bruised spots Fresh, uniform Clean leaves and stems Dirty, diseased, insect damage, discolored, shriveled One and one-half inches to three inches in size; tender; even color Trim leaves to about one inch of vegetable; trim off long roots Oversized, wilted, hard and pithy

8 Lettuce (Head) Firm, crisp, fresh Head in good condition Leave most of wrapper leaves in tact Best to remove few outer leaves after you get to show, as they protect the head Cut stem or butt with knife leaving one-forth to one-half inch Wilted, dry Shriveled, loose or bolting heads Muskmelons or Cantaloupe Clean, firm Free from soft spots, scratches, decay Netting should be deeply ridged over entire melon Even, good color Determine ripeness by the "full slip" - vine should detach clean at attachment to melon Okra Onion Over or under ripe Coarse netting Poor color, blemishes Too much yellow indicated over ripeness Uniform in size, shape, color and maturity Typical of variety Pods should be harvested when half grown, two to four inches long Trim stems one-half to one inch Pods woody and fibrous Green Onions - one-half to one inch in diameter, showing no bulge Clear white color, dark green tops About six inches long, roots trimmed to one-half inch Dry Onions - Uniform in size, then neck Good color and shape for variety Cut tops leaving one to two inches on bulb; remove rootlets. Outer scale can be carefully removed, but if damage occurs in inner scales, it is scored down heavily. Too many layers of skin removed, thick, soft neck, sunburned. Cracked scales, damaged.

9 Pepper, Bell Pepper, Chile Potato Uniform, true to variety, firm, heavy, smooth, free from blemishes Stems should be attached; all specimens should have the same number of lobes or sections, varying from one to four, solid green color. Dull, rough texture Off color, sunscald Uniform in size and shape Good color, firm Free from blossom-end rot Straight Stems attached Discoloration Shriveling Immature Skin blemishes Medium size (8 to 10 ounces), 3-6" long for Russet, 2-4" long plump, firm, smooth diameter for Red Immature, blemishes Rough in shape, dirty Select for good uniformity, size and color Free from green color, sprouting and shriveling Pumpkins & Squash Pumpkins and squash are difficult to describe because of the great variations available on the market. The items for judging should be representative of the variety; all should have 1/2 to 3" stems to prevent leaking. Pumpkins Mature, smooth Evenly colored surface (green color indicates immaturity) Fruits may vary from round to oblong Surface is grooved Cut from stalk, leaving two to three inches of stem attached Misshapen, immature fruit

10 Summer Squash Fruits small and tender enough to mark with fingernail; ideal length is six to eight inches, 1-2" in diameter Scallop Squash Winter Squash Merit: Sweet Corn Tomato Trim stems to one inch by cutting from vine Fruits large and over-mature Fruits small, three to six inches in diameter, with or without stems Uniform color Free from blemishes, insect and disease damage Fruit typical in shape and variety Fruits should be mature and the rind hard, not easily marked with Trim stem to one inch Immature Insect and mechanical damage Uniform in length, size and color according to variety, kernels full grown and in the milk stage Cut stems neatly below the point where the husks are attached If cut high, husks will fall and ruin appearance. Frequently silk is removed to tip of ear by pulling Immature, unfilled grains, over-ripe and hard, uneven rows. Not filled to tips of ears, worm damage. Medium size, firm Color clear and typical of variety Clean, no growth cracks All with stems closely trimmed or all stems removed. Remove blossoms attached. Coarse, over or under-ripe, bruised, soft cracks or corrugation Scarring

11 Watermelon Good weight for size Medium to large in size Bright intense green color or even striping over melon. Yellow rather than white spot where melon rested on the ground. Form even and regular without bulges or furrows. Trim stem to one inch Light in weight, uneven shape or color, blemishes Ground spot white Special Points to Consider in Selection and Judging Fruits: Apples Specimens should be typical of the variety, uniform in size, color and maturity Free from insect, disease and mechanical damage Size medium to large, but size is not important factor. Stems should be left attached; remove leaves and spurs Not uniform, blemishes Grapes Pears Peaches Plums Typical of variety Berries should be uniform in size, color and maturity Uniform in shape, size, color and maturity, typical of variety Leave stems attached Uniform in every respect with the ground color of the fruit yellow Stems of peaches need not be present, but should be uniform with or without stem Care in handling to prevent bruising is a must Uniform and typical of variety, fresh, plump and full color, free from damage Stems attached; do not remove natural bloom
