Effect of Boron on flower and fruit set and yield of ratoon Brinjal crop
نویسنده
چکیده
This investigation was undertaken to study the effect of boron on flower and fruit setting and yield of ratoon crop of brinjal (Solanum melongina L) in the Eastern Region of Sri Lanka. The treatments were arranged in a Randomized Complete Design (RCBD) replicated three times. The treatments were defined as follows: T1-50 ppm, T2-100 ppm; T3-150 ppm and T4Control along with recommended fertilizer. All other agronomic practices were in accordance with the Department of Agriculture. The results showed that foliar application of boron (H3BO3) at 150 ppm increased the number of flower buds/plant (70%), number of flowers/cluster (141%), number of flower clusters/plant (48%), total number of flowers/plant (122%), percentage of flower set (30%), percentage of fruit set (46%), number of fruits/plant (216%) and fresh weight of fruits/plant (88 %) than that of control. It was, therefore, concluded that foliar application of H3BO3 at150 ppm (at flowering stage) could increase the percentage of flowering, fruit set and fruit yield per plant of ratoon crop of brinjal.

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

The influence of late-season boron (B) application on the bud B concentration and fruit set was studied in sweet cherry (Prunus avium L.). The experiment was carried out on 5-year-old ‘Summit’ and ‘Hedelfinger’ trees on rootstock Gisela 5 in Fruit Growing centre Gačnik. Trees were sprayed with B (1% Bortrack) or water (control). Differences in B concentration were measured between cultivars, th...

Despite problems of low fruit set, small fruit size and alternate bearing, the Hass cultivar dominates commercial avocado production worldwide. To increase yield and fruit size, gibberellic acid (GA3) (25 mg L−1) was applied at different stages of ‘Hass’ avocado tree phenology: (i) mid–late April (flower abscission), end of June–beginning of July (fruit abscission and beginning of the exponenti...

Olive is one of the most ancient fruit trees and has been cultivated for its oil for thousands of years. A mature olive tree produces about 500,000 flowers. They are borne on inflorescences termed panicles. The number of flowers and their distribution on the inflorescence are specific for each cultivar but can change from year to year. The flower position on the inflorescence affects its gender...
