Cattleya is one of the orchid genera, it has many fans. Labellum is large and strike colors. Intergeneric crosses have been made to produce soft colored flower, such as white, pink, red, yellow and brown. Cattleya orchids are known to have large flowers, and they are commonly referred to as The Queen of Orchid. These species are cultivated by several botanists as cut flower commodities. The price of cattleya is costly, so it becomes a business opportunity that needs to be developed. This study aims to examine the types of foliar fertilizers and planting media used on the growth of cattleya orchids. It was conducted between May and August 2021 in the experimental garden of the Faculty of Agriculture, UPN Veteran Yogyakarta using a Split Plot Design with factorial. The first factor, which is foliar fertilizer, consists of quick grow, AB mix, and focus grow. The second factor of planting media includes fern roots, black moss, and kadaka roots media. The result showed that AB Mix on fern and kadaka media produced similar plant height compared to other treatments. While on kadaka media, it produced the best leaf length and width, as well as shoot length. Furthermore, the shoot emergence and the number of roots did not show a significant difference. The plants that received quick grow treatment on kadaka and black moss media had similar growth. The number of roots provided the best growth of kadaka and ferns. Further study should be conducted to test AB Mix with various concentrations and planting media.

The use of foliar fertilizers and coconut water is potential; foliar fertilizer is the alternative medium and coconut water is the plant growth regulator (PGR) in the banana tissue culture. This study aimed to examine the ability of foliar fertilizer to substitute Murashige and Skoog (MS) media and coconut water as the main source of cytokine. There are two factors in this research. The first factor is the media, which consist of three levels, i.e. fully MS, ½ MS + ½ foliar fertilizer and fully foliar fertilizer. The second factor is the coconut water with four levels of concentration i.e. 50, 100, 150 and 200 ml l<sup>-1</sup>. The results show that fully formulated foliar fertilizer had not been able to substitute or even compete with a fully MS media, but conversely foliar fertilizer was used to substitute ½ MS media. This can be seen from the parameters of shoot length, leaf length, root number and root length with the highest yield that was found in MS media (8.7, 4.66, 3.33 and 3.23 cm). The 50-100 ml l<sup>-1 </sup>concentrations of coconut water showed the best results by giving a significant effect on the number of roots and root length. The acclimatization of plantlets in this study was nearly 100%, indicated by the formation of a complete organ.

The effect of vernalization method and duration on off-season cut flower production of Lysimachia clethroides Duby was examined. Rhizomes harvested in October were cooled for 0, 4, 6, 8, 10 or 12 weeks at 4 ± 1 °C in crates with unmilled sphagnum peat or in 3.75-L pots with potting media prior to forcing in a warm greenhouse. After 6 or more weeks of cooling, shoots emerged from crate-cooled rhizomes in higher percentages than from pot-cooled rhizomes. However, only the duration of cooling, not the method, affected the rate of shoot emergence, visible bud formation and anthesis of the first bud in the raceme. As cooling increased from 0 to 12 weeks, the greenhouse days required for shoot emergence, visible bud formation and anthesis decreased linearly. The number of flowering flushes and flowering stems varied quadratically with cooling duration, and the highest yields occurred when rhizomes received between 4 and 10 weeks of cooling. As the number of successive flowering flushes increased, the stem length increased linearly while the stem diameter decreased linearly. High numbers of flowers were produced rapidly after 10 weeks of cooling.

The Impact

Background: The present investigation is an attempt to study the effect of different harvesting and threshing methods on germination and seedling vigour of dhaincha. The use of a combine harvester to harvest dhaincha will be an effective alternative method that has not been widely tried. However, work on different methods of harvesting and threshing of dhaincha is limited. Hence, a study was conducted to evaluate the impact of various harvesting and threshing methods on germination and seedling vigour of dhaincha. Methods: This study was conducted at Anbil Dharmalingam Agricultural College and Research Institute, TNAU, Tiruchirappalli, Tamil Nadu. The dhaincha crop was harvested and threshed using four different methods viz., manual harvesting and manual threshing, manual harvesting and threshing by tractor treading, manual harvesting and mechanical threshing and harvesting and threshing by combine harvester. The resultant seeds were tested for mechanical damage and germination potential. The experiment was laid in completely randomized block design. Germination was tested by roll towel method using 100 seeds in four replications. Germination percentage, root and shoot length were measured in seven days after sowing from ten randomly selected seedlings in each replication. For the estimation of dry matter production, ten seedlings were selected at random and kept in a hot air oven maintained at 85oC for 24 hours after measuring their root and shoot length and vigour index was calculated. Mechanical damage to seeds was observed by ferric chloride test. Seed recovery per cent was calculated based on the 100 kgs of dhaincha seeds were cleaned and graded treatment wise using cleaner cum grader and the seeds retained on the bottom sieve were weighed and expressed as per cent of total quantity of seed. Result: The results revealed that the significant difference was found among the different harvesting and threshing methods. The seeds harvested and threshed by manual method recorded 85 per cent germination followed by seeds harvested manually and threshed by mechanical threshing (84 per cent) and seeds harvested manually and threshed by tractor treading (80.5 per cent). The lowest germination of 80.0 per cent was recorded by combine harvesting. From this study, it could be inferred that combine harvester is a modern method for harvesting of dhaincha that saves time and labour when compared to all other methods.

Effects of row spacing, blended fertilizer rates, and varieties on some agronomic traits of chickpea were evaluated with the objective of investigating response of Kabuli and Desi type chick pea varieties to blended fertilizers rates and interrow spacing. The study was done using split plot design interrow spacing as a main plot, and fertilizer and variety as a subplot, where three row spacings (20 cm, 30 cm, and 40 cm) were assigned to the main plot while the factorial combination of four blended (NPSB) fertilizer rates (0 kg/ha, 50 kg/ha, 100 kg/ha, and 150 kg/ha) and representative of Kabuli and Desi type chickpea varieties such as Arerti and Mariye, respectively, were assigned to the subplot. Main effect of interrow spacing did not show significant difference on many studied agronomic parameters. Similarly, main effect of blended fertilizer rates and varieties did not reveal a significant difference for the studied parameters. However, significant differences were obtained on phenology, yield components, and yield for the varieties. Blended fertilizer rates utilized in Tselemti District did not show differences in most of studied traits. Reasonable row spacing of 20 cm for both types of chickpea could be used for the studied area.

Flower Bud Development

Leucocoryne, a native to Chile, has violet, blue, or white flowers and is increasing in popularity as a cut flower. The effects of storage temperature and duration on flower bud development, shoot emergence, and anthesis were investigated. Bulbs stored at 20 to 30 °C for 22 weeks produced 3.4 flower stems per bulb between March and April. Bulbs stored at 20 °C flowered earliest, followed by those stored at 25 °C. Bulbs stored at 30 °C flowered last. After 16 weeks of storage at 20 °C, a further 2 weeks dry storage at 15 °C before planting resulted in 1 month earlier flowering with no reduction of the number of flowering stems. As dry storage at 20 °C increased to 11 months, the time to emergence and flowering decreased. After dry storage at 20 °C for 12 months, the primary flower stems aborted and secondary stems then developed. Secondary and tertiary flower stems tend to commence flower bud development after the flower bud on the primary flower stem has reached the gynoecium or anther and ovule stage of initiation.

Productivity improvement of edible bamboo shoot of existing plantation of Bambosa balcooa was assessed over three years in homestead of fringe villages of Hollongapar Gibbon Wildlife Sanctuary, Assam. Edible shoots are harvested from first week of June to first week of September every year for consumption. Shoot emergence was recorded significantly high in treatment T2 during 2nd and 3rd year of the study. More or less same value was observed in shoot length and shoot weight in treatment T2 and T3. Application of fertilizer considerably increases nutrient status of soil. However, the percentage of organic carbon, total nitrogen available phosphorus and exchangeable potassium found significantly high during 2nd and 3rd year of study. At the harvesting stage less value of nutrient was recorded due to absorption by sprouted clums. Observation reveals that T2 is the best combination of NPK and plying vermicompost that improves growth of shoot and clum production significantly.

Years of tree planting are 2013-2014, scheme is 5x2 m, density - 1000 trees / ha. The objective of the research is to assess the influence of distant cherry hybrids on its growth and development in the garden. The influence of rootstock forms Novella and Turgenevka plants varieties is presented. The general condition of cherry plants was good and varied from 4.2 to 5.0 points, the degree of flowering was at the level of the control variant. During the years of study, the indicator of the fruiting degree in the Novella variety was higher. The Novella variety trees on forms 74324, 74363, Ts-8-101 are medium-grown. Restrained growth of Turgenevka variety plants was observed in combinations with rootstock forms 74324 and 74340; medium-grown plants – 74322, 74332, 74336, 74363, Ts-8-1014; tall – growing – 82987. Plants of the Turgenevka variety in combinations 74324 and 74336 showed incompatibility, breaking off at the place of grafting concretion. The greatest value of the length of the one-year shoot was noted in Novella variety on the rootstock 74340, and the smaller one was in Ts-8-101. In cultivar Turgenevka a longer one-year shoot length was noted on forms 74332 and 74363, the smallest - 74336. The best rootstock forms among those studied in terms of growth and development for cultivar Novella are 74322, 74332.74340, 82987, Turgenevka – 74322, 82987.

Existing knowledge about biochar is derived from trials where biochar incorporation into the soil is done by hands, a practice too tedious to scale-up to commercial levels. To enhance scalability, biochar incorporation needs to be integrated into conventional mechanised tillage systems. This study aimed at assessing the effects of incorporating biochar by power tiller and ox-plough on soil water retention, maize growth and yield. A 2 x 3 factorial experiment was conducted in a split-plot design with biochar incorporating method as a main plot factor and biochar level as subplot factor, on ferralsols of central Uganda. Incorporation methods were by power tiller and ox-plough with hand mixing in planting basins as a control, while levels of biochar were 0 and 10 t ha-1 application rates. Data was analysed using two-way ANOVAs in Minitab for significant differences among incorporation methods. Results showed that incorporating biochar by power tiller significantly increased water retention effect of biochar by 27.5% (p < 0.05), while no significant effect was observed (p ≥ 0.05) when incorporated by ox-plough, compared to hand mixing. No significant difference on growth and yield was observed (p ≥ 0.05) as a result of incorporating biochar by power tiller and ox-plough instead of hands in planting basins. These findings suggest that biochar incorporation can be scaled-up, to commercial levels, through the use of power tiller and ox-plough, without negative effects on biochar performance. It is recommended that promotion of biochar technology encompasses the use of power tillers and ox-ploughs to enhance scalability.

Okra (Abelmoschus esculentus L.) is one of the most important vegetable crop of Nepal. Its yield and growth parameters are affected by different cultural practices. This study was conducted at Olericulture Farm of Agriculture and Forestry University, Rampur, Chitwan, Nepal during April 29 to July 9 of 2018. The field experiment was carried out in split plot design using three replications. The treatments consisted of three intra row spacing (30, 45 and 60 cm) and four different mulching materials (Silver plastic, Panicum repens, Lantana camara and bare soil). The objective of this experiment was to assess the effects of various intra-row spacings and mulching materials on growth and yield of okra. The effect of mulching materials on okra yield was found significant. The okra yield was highest (8104 kg/ha) under silver plastic mulch followed by control (5161kg/ha), Panicum repens (3901kg/ha) and Lantana camera (3701kg/ha), respectively. Silver plastic mulch enhanced the growth parameters like canopy length, plant height, leaf number, leaf length, girth and yield of okra. The spacings provided non significant effect on okra yield, however the yield of okra was highest (7295 kg/ha) under 30×30 cm spacing followed by 45×30 cm (4660 kg/ha) and 60 cm × 30 cm spacing (3703 kg/ha), respectively. Combination of silver plastic mulch along with 30 cm × 30 cm spacing provided the highest okra yield. This study suggests that farmers of the Chitwan should grow okra at spacing of 30 cm × 30 cm and under silver plastic mulch to produce higher yield.

Objective: Evaluate the development and gas exchange of pre-sprouted sugarcane seedlings in different substrates. Study Design: A randomized complete block design was used with two genotypes, three types of substrate (2 x 3), four replicates and five plants per replicate, totaling 120 plants. Location and Duration of Study: Department of Crop Sciences of the Center for Agrarian Sciences, Universidade Federal de Paraíba in the city of Areia, Brazil, between August and October 2018. Methods: The following were the treatments: T1 – genotype 1 in commercial substrate; T2 – genotype 1 in commercial substrate + bovine manure; T3 – genotype 1 in bovine manure + sand; T4 – genotype 2 in commercial substrate; T5 – genotype 2 in commercial substrate + bovine manure; T6 – genotype 2 in bovine manure + sand. Variables analyzed: height, diameter, dry mass of shoot and root and physiological response of seedlings. Results: A significant difference at the 1% level was found for the dry matter of the seedling roots among treatments with difference substrates. A significant difference at the 1% level was also found for shoot length and a significant interaction at the 5% level was found between genotype and substrate for this characteristic. Significant effects were found with regard to the rate of photosynthesis, stomatal conductance, transpiration and carboxylation efficiency. Conclusion: The substrate with manure + sand favored the accumulation of root dry matter and shoot length. Genotype 1 exhibited its best performance with regard to photosynthesis and stomatal conduction in the treatment with the commercial substrate and demonstrated greater carboxylation efficiency than genotype 2, independently of the substrates. The pre-sprouted seedling production system needs to be explored further to obtain greater information regarding the nutritional requirements and characteristics of the genotypes.
