SQUASH PRODUCTION GUIDE

Bush sitao can be raised in both lowland and upland areas. It can adapt to any soil type but best to plant in sandy to clay loam soil. It can tolerate acidic soil but it will not produce high yield. It can grow in low and high rainfall but only briefly as it will rot due to water-logging. It can survive only if the dry season is brief and not too long. For long dry spell, scheduled watering is needed to preserve or conserve moisture in the soil while the plants are growing.

In selecting a variety, give emphasis the duration of growth, the yielding capacity, tolerant against pests and diseases and easily adapt in extreme weather condition.

Plow and harrow the land 3 times. Loosen the soil well to be able to have good soil condition. Every time there is emerging weeds, remove them through plowing or harrowing.

Inoculate the seeds with Rhizobium before planting. Plant 1 seed per hill. Spacing is 30 centimeters apart or 75 centimeters between rows.

As fertilization is necessary to keep plants healthy and give higher yield, do the following:

In one hectare land:  30 kilograms urea during planting, 100 kilograms single superphosphate at planting time, 60 kilograms muriate of potash at planting time, 5 bags complete fertilizer (14-14-14), Superphosphate (side-dressing 3-4 weeks after germination).  Organic fertilizer (decomposed dry leaves, straws and animal manure 56 tons per hectare, if available). In acidic soils (4 tons of lime one month before planting to good soil pH)

Water the plant during intense dry season for the plants to give higher yield. Bush sitao can tolerate drought but watering may protect it from dryness in the soil or lacking moisture content that may affect the fruiting of the vegetable. Watering may be done during planting, early seeding or first 15 days, at flowering and pod setting (50 days after planting).

Use furrow irrigation in 10 days interval. Watering induce the plant to grow fast, healthy and high pod setting.

Control pests and diseases are normal farming practices. Without it, the plant has stunted growth, damage leaves and fruits, lower yields.

Most pests that attack bush sitao especially after germination of seeds are pod borers, leaffolders and aphids. Spray the plants with insecticides as soon as the pests started attacking the plants. Spraying with pesticides is the only way to get rid the enemy of the plants.

Bush sitao still has another threat in its growing days. The plants are subject to many diseases like fusarium wilt, cowpea rust and leaf spot. Spray the plants with fungicides to remove the infection. Another way to minimize the effect of the virus is to look for resistant variety.

Include weeding as part of your cultural practices. Remove the weeds every now and then if found to germinate to clean the field from the hazard that later on will affect the health of the plants. Schedule the weeding of the plants 3 times for one season. Additionally, enforce spot weeding every time weeds appear.  Hill-up the plants to loosen the soil 3 weeks after planting.

Harvest the plant 12 days after the flowers open. It may be done if the pods reach the required maximum length and width but not to allow young pods to mature as it can no longer sealable to market. The second and succeeding harvest should be done every 3 days to ensure that pods still young and fresh.
