Introduction

Avocado plantation in Pakistan was started during the year 1955 at Hill Fruit Research Station (HFRS) Murree, Punjab Pakistan. A hectic research was conducted for standardization of production technology and varietal performance comparisons among changing agro climatic conditions. Avocado has wide adaptability range (Gill et al., 2018) for different varieties in temperate and semi temperate areas. Small land holding and limited water resources are the major hurdles for fruit production in targeted areas. It is need of the day to produce the precious fruit ‘avocado’ for judicial use of land and water resources in combination with agro climatic conditions of sub-mountainous areas. These studies were initiated for identification of most successful and high yielding variety of avocado during 2018 and carried on for 3 years for data recording. The experiment was concluded in 2021 for final recommendation.

Avocado is a crop with enormous economic significance among farming communities (Cáceres-Zambrano et al. 2022; Gómez et al., 2023). The gaps in cultivars improvement, agronomic management and postharvest handling also need due attention to improve the productivity of avocado in target areas (Sora, 2023). The locality and environment has deep impact on production and adaptability of avocado cultivation along with credit facility and strong infrastructure. Supply chain also helps for enhancing production level of avocado variety ‘Hass (Mopan et al., 2023).

Avocado varieties ‘Pinkerton’ and ‘Bacon’ are recommended for Raya valley and other areas having similar agro-ecologies. Jalata (2021) stated that crop diversification can be useful strategy Avocado can be considered as important alternative crop for the farmers as its suitability to the agro ecologies, high domestic and export potential avocado can provide multiple benefits to the farmers to improve their livelihood (Abebe et al. 2022).

Avocado can provide multiple benefits to the farmers especially to improve farmers’ income, increase land productivity, sustainability and food security (Malekela, 2022; Legesse et al., 2023). Furthermore, it has complementary advantages for business and economic activities of growing towns in nearby areas. Avocado is a high yielder, the nutritional value of avocado is recommendable for nutritional deficient people in developing countries.

There is relationship between quality of fruit and production locality, which allowed discriminating fruits by their region of origin. New technologies increase avocado productions in target areas and may positively contribute to improve livelihood through nutrition and income generation of stakeholders (Henao et al. 2019; George et al., 2019).

There are even important factors for the growth of avocado trees were determined: Forest border, slope, permeability, soil depth, land use capability, protected areas/forbidden zones, average and minimum temperature stated that suitability values of growing models were compared to Hass avocado production; models were able to identify both novel areas with potential for cultivation, and sites where this crop has been planted in relatively unsuitable areas. Avocado cultivation is identifying areas with environmental potential in Colombia and currently not planted with Hass avocado (Selim et al., 2018; Gil et al., 2018).

These studies were arranged for standardization of promising verities for cultivation in Pothwar region and Upper Punjab areas after a complete adoptability study. Production and yield performance was compared in three ecologies. Yield and sporting aspects of fruit production stages were studied and analyzed for decision.

Materials and Methods

The study was conducted in three different locations and districts (Hill Fruit Research Station Murree, Horticultural Research Station Nowshehra, and Rehan Farm, Sargodha) Twenty-five years old trees of avocado variety Murree Gola and Ceylon Blue were selected for collection and comparison of production data. Final recommendations of variety were given on the basis of performance in selected agro climatic conditions.

Experimental units (avocado trees) were approximately of same age and canopy size. All the treatments were maintained according to standard agricultural practices i.e irrigation, fertilization, pruning and health management. Data was recorded when fruit showed colour change indicating fruit maturity. Fruit maturity stage was considered a standard when fruit was ready for wholesale marketing. Harvesting of fruit was made manually and weighed on Electronic balance.

The experiment was laid out according to Factorial Design of layout with two factors i.e Avocado varieties (Murree Gola and Ceylon Blue) and three experimental locations with 4 replications of each treatment. Data was statistically analyzed for final design of the results.

Flowering time (week): Flowering time was recorded (week) on opening of first flower cluster.

Anthesis period (days): Anthesis period was recorded by counting the No. of days from opening of first flower cluster to opening of last flower cluster.

Fruit maturity (days): Fruit maturity was calculated by counting the No. of days from fruit setting to horticultural maturity of the fruit i.e., color change stage of fruit.

Fruit weight (g): Average fruit weight was calculated by weighing 20 randomly selected fruits of each variety after attaining the horticultural maturity.

Yield per tree (Kg): Yield per tree was calculated by weighing fruit collected after complete harvesting operation.

Results and Discussion

Production data was collected and manipulated for conclusion of final recommendations. Production parameters considered in these studies are as following.

Flowering time (week)

Data regarding flowering time (Table 1) of both avocado verities collected from different experimental sites depicted that Murree Gola variety is about one week earlier in flowering than Ceylon Blue which reveals difference in varietal behavior of avocado. Varieties showed variable behavior in different locations which may be due to agro climatic conditions and genetic makeup of the variety. Flowering behavior of Murree Gola in various ecologies showed that this variety is suitable for sub mountainous and plane areas having early spring. While data collected from Ceylon Blue shows its better suitability in lower and foot hills. Our studies are in conformity with Camilo et al. (2019).

Anthesis period (days)

Data regarding anthesis period (Figure 1) reveals that anthesis period of Murree Gola is longer than Ceylon Blue. This might be due to genetic difference of both varieties of avocado which may be helpful for successful pollination and minimize the climatic risk. Our results are in conformation with the data recorded by Selim et al. (2018).

 

 

 

Fruit maturity (days)

Data regarding fruit ripening period depicted that Murree Gola variety is later in ripening as compared to Ceylon Blue. This fruit ripening behavior of both varieties may be due to difference in genetic makeup and climatic conditions of study area. This differential behavior in different localities has also been reported by Guillermo et al. (2018).

Fruit weight (g)

Data regarding average fruit weight revealed that Murree Gola produced heavier than Cylon Blue in all localities of the study area. Fruit weight was improved in slightly warm areas as compare to colder areas which might be due to climatic conditions of the site. Our conclusions is in line with studies of Sora (2023) and Juma et al. (2019).

Fruit yield/ Tree (kg)

Data regarding yield/tree reflects that fruit yield differs in different localities under the study area. Yield increases in slightly warm areas as compared with cool climatic conditions. It might be due to genetic makeup of the variety and better photosynthesis activities of leaves. Similar results had been reported by Abebe et al. (2022) and Nkansah et al. (2016).

Conclusion and Recommendations

Murree Gola variety of avocado is suitable for lower Hills and foot mountains where northern areas cool winds are blocked by highlands and wind breaks. Ceylon Blue is most suitable for plane areas having cool, humid environmental conditions.
