“…Thus, it was observed that unit change in canopy volume and trunk cross-sectional area respectively caused 1.85 and 0.40 times more change in fruit yield. Dogra and Kumar (2018) found a highly significant and positive phenotypic and genotypic correlation of fruit yield with trunk girth in peach genotypes. They also observed maximum positive direct effect of tree volume on fruit yield.…”

Aim: Increasing the input use efficiency by planting of guava on raised bed, mulched with black polythene sheet along with fertilizer application through drip and foliar spray of micro-nutrients (zinc and boron). Methodology: Experiment was carried out during 2015-2019 for mrig bahar crop in Lalit guava planted at 3 × 3 m spacing in ICAR-CISH, Lucknow with 5 different treatments (T1 = Raised bed +drip irrigation @ 80% PE + fertigation @ 75% RDF + mulching with 100µ black polythene + micro-nutrient spray in July and August @ 0.2% each of zinc sulphate and boric acid, T2 = Raised bed + drip irrigation + fertigation + mulching, T3 = Raised bed + drip irrigation + fertigation + micronutrient sprays, T4 = Raised bed + drip irrigation +micro-nutrient sprays + soil application of RDF @ 50:25:50 g N:P:K, T5 / control = Flat bed + soil application of RDF + basin irrigation). Results: Canopy volume, trunk-cross sectional area and yield were significantly increased in T1, which could be attributed to better microclimate in root zone, resulting in improved growth and yield. Interpretation: The findings of this research have generated the technique of improving space, water and nutrient use efficiency under high density planting system of guava cv. Lalit in subtropical climate which will help the guava growers for sustaining quality production.

“…The fruit quality of this early-ripening cultivar is excellent, both for fresh consumption and industry. Thus, it is believed that cultivar BRS Libra may be interesting, mainly for small farmers who sell fresh fruit (Raseira et al 2010) AS Santana et al Fruit yield, however, is a quantitative, low heritability trait, controlled by several small effect genes and highly influenced by the environment and genotype × environment (GE) interaction (Dogra and Kumar 2018). The GE interaction is an important information for breeders because it reflects the yield variation not explained by the individual effects of genotype and environment (Vaezi et al 2018).…”

The objective was to evaluate the adaptability and yield stability of different peach rootstock genotypes in subtropical climate in an experiment in Chapecó, Santa Catarina, Brazil. Twenty-one rootstocks under the scion cultivar 'BRS Libra' and one genotype from self-rooted nursery trees were evaluated. The 22 genotypes were evaluated as fruit set and fruit yield in the growing seasons 2014/15, 2015/16, 2016/17 and 2017/18. Adaptability and stability were measured by the GGE biplot method. In the four years of evaluation, plants from self-rooted nursery trees had higher fruit set, yield as well as greater stability. On the other hand, the instability of plants grown on rootstocks from species other than the scion cultivar was greater. It can be concluded that under the tested conditions, the self-rooted genotype of 'BRS Libra' is a potential alternative for peach growers.
