ABSTRACT Potato seed is one of the largest costs of a crop. This is mostly due to the incidence and spread of viruses that occurs when the crop is grown in the open field. Thus, it is necessary to obtain virus-free potato plantlets through meristem isolation, with subsequent cultivation in a protected environment, where it is easier to control virus-spreading insects. One way to increase greenhouse viability is by multiplicating potato seed using high technology systems, among them, aeroponics. The objective of this work was to determine the effect of planting density on the growth and yield of potato plants cv. Agata in aeroponic cultivation, and the effect of harvesting dates and planting densities on the dormancy of harvested minitubers. The number of stems, leaves, and the number and fresh weight of minitubers/plant reduced when planting density was increased from 60 to 180 plants/m2. However, the number of stems, leaves, initiated minitubers, and the number and fresh weight of minitubers/m2 increased when planting density was increased from 60 to 180 plants/m2. The maximum number of type III minitubers (>30 mm) was 613/m2, obtained at the density of 180 plants/m2. Plant density did not affect the dormancy of harvested minitubers, but harvesting date did. Minitubers obtained from latter harvesting dates had a shorter dormancy period. Minitubers harvested at 78 and 64 days after transplanting sprouted 21 and seven days earlier than those picked at 50 days after transplanting.

Performance of potato seed tubers of first, second, third, fourth, and fifth generations were evaluated against PVY and PLRV. Potato plants grown from first generation seed tubers were free from PVY infection. Incidence of the virus was the minimal at second generation, which increased afterwards steadily by third, fourth, and fifth generations. Incidence of PLRV was minimal at first generation. It increased gradually with the advancement of generation seed tubers showing the highest incidence at fifth generation. The highest plant growth and tuber yield were recorded at second generation, which was followed by third, fourth, and fifth generations. The highest reduction in plant height, tuber number, and tuber yield were recorded in 5th generation due to infection of PVY and PLRV.

<p>Mungbean is one of the strategic annual food crops that needed by Indonesian people because of the high protein and minerals. Production of mungbean in Indonesia always decreases. Cultural improvements are needed to increase productivity i.e by appropriate fertilization and plant density. The experiment objective was to find out the optimum dosage of organic fertilizer and plant density for the growth and yield of mungbean. The experiment was carried out using factorial completely randomized design (CRD). The first factor treatments were organic fertilizer which consisted of 0, 5, 10, 15, and 20 ton ha<sup>-1</sup>, while the second-factor treatments were planted density which consisted of 1 and 2 plants in the hole. Organic fertilizer of 5 ton ha<sup>-1</sup> gave the best result for plant height, number of branches, flowering age, number of pods, fresh weight and dried straw, weight of 100 seeds, number and weight of seeds, small of seeds number and P nutrient uptake of the plant. The 2 plants per hole gave the best result for branches number, pods number and number of small seeds. Application of 5 ton ha<sup>-1</sup> organic fertilizer and 1 plant per hole gave better yield. No interaction of organic fertilizer and plant density to mungbean growth and yield.</p>

A field experiment was conducted during kharif, 2019 at College Farm, Professor Jayashankar Telangana State Agricultural University, Telangana. The present study was conducted to know the effect of different planting densities and nitrogen levels on the growth and yield of Finger millet. The soil of experimental site was loamy sand type, slightly acidic in pH (6.43), non-saline in EC (0.15 dSm-1), low in organic carbon (0.42%), low in available N (201.6 kg ha-1), medium in available P (25.3 kg ha-1), low in available K (236.25 kg ha-1). The experiment was laid out in randomized block design with factorial concept and replicated thrice with 12 treatments combinations consisting of four nitrogen levels (0 %, 50%, 100% and 150% RDN) and three levels of planting density (S1-solid rows × 15 cm, S2- 30 cm × 15 cm, S3- 25 cm × 15 cm). Results indicated that S1-solid rows × 15 cm recorded highest plant height, number of tillers m-2, dry matter production (g m-2) and S3- 25 cm × 15 cm recorded highest leaf area plant-1 and yield. Application of 150% RDN recorded highest plant growth parameters, grain yield and straw yield. However, it was on par with 100% RDN. It was concluded that planting density of 25 cm × 15 cm among spacings and 100% N among nitrogen levels proved to be a viable option for getting higher productivity and profit under rainfed conditions of central agro climatic zone of Telangana.

This study aimed to determine the effect of different biostimulant applications (solid and liquid) on the growth and yield of mustard plants. This study used a single factor Randomized Block Design (RBD), consisting of solid or liquid biostimulant treatment, each has twelve levels, i.e. K0 = without biostimulant, K1 = NPK 1 g per plant, solid and liquid biostimulant each consisting of 10 treatments = B1, B2, B3, B4, B5, B6, B7, B8, B9, B10. Solid biostimulant was given at 2.5 g per plant and liquid biostimulant at 10 ml per plant. The results showed that liquid biostimulant gave a significant effect on plant height, crop fresh weight, and crop dry weight; whereas solid biostimulant gave a very significant effect on entire weight, i.e. fresh weight of mustard plant, fresh root weight, and crop dry weight. The best treatment for liquid biostimulant was B1 treatment; whereas for the solid biostimulant was B7 treatment.

Two experiments were conducted in 1988 and 1990 to determine the effects of planting density, N fertilizer rate, and cultivar on fresh yield of dill. A split plot design was used in the first experiment in which planting density (one versus two rows per bed) was the main plot treatment and N rate (0, 56, 112 kg/ha) was the subplot treatment. A European cultivar, `Crown,' was used in the first experiment in 1988 while `Long Island Mammoth' was planted in 1990, N was applied in split applications while both K2 O and P2 O5 were preplant incorporated at the rate of 134 kg/ha. Planting was done on bedded rows approximately 66 cm wide and 15 cm high. N fertilizer application did not affect yield in 1988. Leaf, stem, flower, and total yields were greater for the high density planting. The second experiment evaluated yield of four cultivars (`Tetra,' `Bouquet.' `Long Island Mammoth,' and `Crown') using a randomized complete block design. `Long Island Mammoth' and `Tetra' produced greater leaf and total fresh weight while `Long Island Mammoth' and `Bouquet' produced greater flower fresh weight.

A pot experiment was conducted at BAIF Development Research Foundation, Urulikanchan, Pune, India during 2014-2016 to study the biomass production performance of four cactus accessions as a source of fodder for livestock. Single matured cladodes of individual accessions were planted in plastic pots during August 2014 and were harvested 18 months after planting. The growth and yield observations were recorded during harvesting and fresh cladodes were analyzed for nutritional parameters in the laboratory. The study revealed that the highest green biomass yield per plant was recorded in accession 1270 (1.74 kg) followed by 1271 (1.45 kg), 1280 (1.39 kg) and the lowest was in accession 1308 (1.36 kg). The maximum fresh weight per cladode was observed in accession 1280 (448.84 g) followed by 1270 (436.75 g), 1271 (394.73 g) and the minimum was in accession 1308 (150.69 g). The more number of cladodes (9.0) were found in accession 1308 followed by 1270 (4.0), 1271 (3.69) and the least (3.10) was in accession 1280. The maximum cladodes area of 333.14 cm2 was recorded in accession 1270 followed by 1280 (310.84 cm2) and the lowest was in accession 1308 (95.61 cm2). The nutritional evaluation of fresh cladodes revealed dry matter in the range of 8.24 to 11.15 %, crude protein 4.00 to 6.03% and crude fiber 7.06 to 8.15%.

Determining the water productivity of maize is of great significance for ensuring food security and coping with climate change. In 2018 and 2019, we conducted field trials in arid areas (Changji), semi-arid areas (Qitai) and semi-humid areas (Xinyuan). The hybrid XY335 was selected for the experiment, the planting density was 12.0 × 104 plants ha−1, and five irrigation amounts were set. The results showed that yield, biomass, and transpiration varied substantially and significantly between experimental sites, irrigation and years. Likewise, water use efficiency (WUE) for both biomass (WUEB) and yield (WUEY) were affected by these factors, including a significant interaction. Normalized water productivity (WP*) of maize increased significantly with an increase in irrigation. The WP* for film mulched drip irrigation maize was 37.81 g m−2 d−1; it was varied significantly between sites and irrigation or their interaction. We conclude that WP* differs from the conventional parameter for water productivity but is a useful parameter for assessing the attainable rate of film-mulched drip irrigation maize growth and yield in arid areas, semi-arid areas and semi-humid areas. The parametric AquaCrop model was not accurate in simulating soil water under film mulching. However, it was suitable for the prediction of canopy coverage (CC) for most irrigation treatments.

A field experiment was conducted in 2005 to evaluate the effect of some isolates of Azospirillum brasilense and Azospirillum lipoferum on growth and yield of lentil (Lens esculenta). Azospirillum inoculation significantly enhanced the early emergence of lentil seeds in the field. The inoculation caused the increase in height of the lentil plants at various stages of growth. Due to inoculation fresh weight and dry weight of lentil plant were increased during pre-flowering and post-flowering stages. Significant increase in the number of pods per plant and grain weight due to Azospirillum inoculation was observed. It was also found that the population of Azospirillum increased significantly in the inoculated root samples of lentil plants.
