Abstract

Pp. 41-42. Weed control in deciduous fruit trees. Six-year trials were completed in 1980. Pre-em. herbicides were applied at the beginning of winter in almonds and apricots at Akhera and at the end of winter in plums at Psimolophon. Herbicides were applied to apples and cherries in early May after snow-melt at Platres. Paraquat at 20 g + diquat 20 g/donum [=0.33 acres] was applied to control emerged weeds. The most effective treatments were methazole at 200-300 g + napropamide 267-400 g, oxadiazon 400-535 g and propyzamide 160-200 g + simazine 134-167 g/donum. In addition, terbuthylazine at 337 g + terbumeton 337 g was successful in apples and terbacil at 267-400 g/donum was successful in peaches. No herbicide treatment adversely affected the crops.<new para>ADDITIONAL ABSTRACT:<new para>Research reported included the following: management, growth and digestibility of fodder barley; fodder oat, barley, lucerne and vetch cv. trials; resowing and fertilizing of grassland; grain barley, durum wheat, bread wheat, triticale and chickpea cv. trials; Vicia faba germplasm collection; cereal/legume rotations; tillage systems and sowing regimes for dryland farming; sowing date, depth and plant density trials with chickpea; fertilizer vetch; the effect of restricted irrigation in July-Aug. on lucerne yield; the effect of type of roughage on milk production and milk composition of dairy cows; and the nutritive value of straw treated with NaOH, Ca(OH)2 and urea.
