Organic agricultural systems are often assumed to be more sustainable than conventional farming, yet there has been little work comparing surface water quality from organic and conventional production, especially under the same cropping sequence. Our objective was to compare nutrient and sediment losses, as well as sweet corn ( L. var. ) yield, from organic and conventional production with conv...

in this study, a landrace melon zarde jalali as the scion and commercial varieties of cucurbita rootstocks cv., shintozwa and ferro-rz was used as the rootstock. grafted plants upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels of 60, 80 and 100% (respectively 4984.32, 6124.82 and 7239.41 m3ha-1) based on total available water depletion with drip irr...

Increasing plant production by protecting the environment is one of main goals today's agriculture. On other hand, use both inorganic and organic fertilizers becoming increasingly extensive. This study was carried out in field conditions to determine effects fertilization on yield quality characteristics industrial tomato (Solanum lycopersicum L., cv. Heinz 1015 F1). For this purpose, contents ...

Cruz, Laguna Philippines to evaluate its effects determine best level for the optimum pechay. is a patented high-analysis formulation with plant nutrients complexed bioactive polyphenols that enhances nutrient availability plants provides biostimulant effect improve vitality activat...

A field experiment was conducted at Zonal Agricultural Research Station, UAS, GKVK, Bengaluru, Karnataka to study the influence of different approaches fertilizer application using soluble and conventional fertilizers on yield, nutrient requirement economics cabbage under drip fertigation. The results revealed that significant higher marketable yield 62.55 t ha-1 recorded in LMH approach follow...

CHIPS 38 Geographic distribution Early blight is widespread in most areas where potatoes or tomatoes are grown, but is especially prevalent in the tropics and temperate zones. The disease is a potential threat where potatoes are grown under irrigation or during times of heavy dew. Early blight is prevalent in all provinces in South Africa and is a limiting factor in production in late summer. E...

Watermelon, Citrullus lanatus (Thunb.) Matsum & Nakai cv. Sugar Baby, were grown in the field as a fall crop in open-top chambers (OTC) in southwestern Indiana with either charcoal-filtered (CF) or nonfiltered (NF) air. Ozone and sulfur dioxide were continuously monitored in OTC and ambient air. There was a significant decrease in marketable yield by weight (19.9%, P = 0.05), percentage of mark...
