The effects of KCl, K<sub>2</sub>SO<sub>4</sub> and KNO~ on the yields of greenhouse tomatoes variety 'Revermun' cultivated on a peat substrate were examined. On the basis of fruit yield, dry weight content in the fruit and the content of K, Ca, Mg, Cl, S-SO<sub>4</sub> in the soil and of N, P, K, Ca, Mg, Cl, S-SO<sub>4</sub>, Fe, Cu, Mn, Zn, Mo in leaf stalks it was found that KCl is the best form foir fertilizing greenhouse tomatoes cultivated on peat. No adverse effects of chlorine at concentrations of 1500 mg Cl/liter peat and 6,0% Cl in the dry mass of tomato leaves were observed.

China is the origin and distribution center of kiwifruit, as well as the country with the largest cultivated area and output of kiwifruit. A previous study found that a new kiwifruit virus, Actinidia yellowing ringspot virus (AYRSpV), has been detected in kiwifruit samples with yellowed leaves. The incidence of this virus was high in kiwifruit plantings in Shaanxi Province. To determine the symptoms of this viral infection and the effects of this virus on the yield and quality of kiwifruits, we measured leaf chlorophyll levels and the fruit yield, total sugar, total acid and dry matter contents of ‘Hayward’ kiwifruits grafted with AYRSpV-infected scions. The results showed that after AYRSpV infection, symptoms including chlorotic ringspots were mainly observed in the spring and gradually recovered with high summer temperatures. A few of the leaves that did not recover showed symptoms of albinism, which lasted until the leaves fell. We found that AYRSpV infection could reduce the chlorophyll content of ‘Hayward’ kiwifruit by 74.61-76.64%, the fruit yield by 14.50-24.10%, the sugar to acid ratio by 50.09-50.57%, and the fruit dry matter content by 1.67-1.78%. Our results showed that AYRSpV infection could significantly affect the yield and quality of ‘Hayward’ kiwifruit.

Five strawberry genotypes ('Rabi 3', 'Camarosa', 'BARI Strawberry 1', 'BADC Strawberry' and 'Festival') were evaluated for their field performance. The maximum number of leaves/plant (14.2), canopy spread (31.82 cm) and runners/plant (7.2) were found with 'Camarosa', 'Festival' and 'Rabi 3' respectively. Festival took the lowest number of days to flower initiation (32.5). The highest number of flowers (23.64) and fruits/plant (19.98) were found in 'Camarosa'. The heaviest (21.83 g) and the largest sized individual fruit (1539.31 mm2) were produced by 'Festival'. Fruit TSS (%) was the highest (15.83) in BARI Strawberry 1. Genotype 'Festival' gave the highest fruit yield (12.94 t/ha) and 'BADC Strawberry' yielded the lowest (6.15 t/ha). Considering growth, yield and quality of fruit, genotypes 'Festival' and 'Camarosa' were found promising under the climatic condition of Salna.Bangladesh J. Agril.
