A field experiment was carried out to study the influence of different irrigation regimes on the panicle and grain growth, relative growth rate of grain, grain abortion, yield and some yield components of four wheat varieties in two growing seasons. Irrigation regimes had significant effects on the aforesaid parameters and the varieties were found to be more efficient under well irrigated conditions. A drastic reduction in panicle and grain growth and yield and increase in grain abortion was noticed when the varieties were grown under rainfed condition. C 306 was found to be the most efficient to have higher values of panicle and grain growth, relative grain growth rate and yield under all the irrigation regimes in both the growing seasons.

A field experiment was conducted at the research field of Faculty of Agriculture and Natural Resources Management, Ebonyi State University Abakaliki during the 2018 farming season to determine the effect of plant density on growth, yield and yield components of groundnut varieties. The experiment was conducted in a 3x4 factorial laid out in a randomized complete block design (RCBD). The treatments comprised three groundnut varieties (SAMNUT 24, 25 and 26) and four planting densities (40,000, 80,000, 120,000, and 160,000 plants ha-1). Each treatment was replicated four times. The parameters measured were plant height, number of leaves per plant, number of branches per plant, days to 50% flowering, shoot dry weight, leaf area index, crop growth rate, relative growth rate, net assimilation rate, number of pod per plant, pod weight per plant, hundred seed weight, number of seeds per plant, shelling percentage and total yield per hectare. The results showed that groundnut varieties were significant in all growth and yield parameters assessed except number of days to 50% flowering, Relative Growth Rate, number of pod per plant, and hundred seed weight while planting density recorded significant effect on all the growth and yield parameters. There were also significant interaction effects of varieties and plant density on plant height, number of branches per plant, leaf area index, relative growth rate, pod weight per plant, number of seeds per plant, and total yield per hectare. This result indicated that SAMNUT 26 and plant density of 160,000 plants ha-1 recorded the highest yield of groundnut and can be recommended for the farmers in the study area.

ABSTRACT The purpose of this study is to determine the effect of interaction and the main influence of vermicompost and NPK Pearl 16:16:16 on the growth and yield of celery plants. This research was carried out for four months, from August to November 2018. This research used a factorial completely randomized design (RAL) consisting of two factors, where the first factor was vermicompost fertilizer (K) consisting of 4 levels, namely 0, 60, 80, 100 g / polybag and the second factor is NPK Pearl 16:16:16 (N) fertilizer consisting of 4 levels, 0, 0.8, 1.6, 2.4 g/polybag. The observation parameters in this study were plant height (cm), relative growth rate (g), root volume (cm3), number of tillers, number of midribs, wet weight of crop (g), and age of harvest (days). The last observation data were statistically analyzed and continued with a BNJ follow-up test at the 5% level. The results showed that the interaction between vermicompost and NPK Pearl 16:16:16 fertilizer significantly affected plant height from week two to week seven, the relative growth rate in the first week, root volume, number of tillers, number of fronds and wet weight per plant. The best treatment is K3N3 (K3 vermicompost fertilizer = 100 g /polybag and NPK Pearl 16:16:16 N3 = 2,4 g/polybag), but it has no significant effect on the age of harvest and the main effect of vermicompost and NPK Pearl 16:16: 16 significantly affected plant height, relative growth rate, root volume, number of tillers, number of midribs and wet weight of the crop, with the best treatment being K3 (vermicompost fertilizer 100 g/polybag) and N3 (NPK Pearl 16:16:16 2,4 g/polybag).

The interactions of seed vigor with herbicides were studied with respect to seedling emergence, growth, and fruit yield of processing tomatoes (Lycopersicon esculentum Mill. cv. UC204C). Seed vigor (speed of germination) was enhanced by priming in an aerated solution of 0.12 m K2HP O4 plus 0.15 m KN O3 at 20C for 5 days followed by drying in forced air at 30C. The vigor of a second subsample of the same seed lot was reduced by controlled deterioration at 13% water content (dry-weight basis) for 6 days at 50C (aged seeds). Primed, aged, and untreated seeds were tested for their sensitivity to napropamide and metribuzin herbicides in greenhouse and field studies. A seed vigor × herbicide interaction was detected only under greenhouse conditions, where aged seeds were more sensitive than primed or untreated seeds to metribuzin. In April and May field plantings, seed vigor influenced the rate and percentage of final emergence and the earliness of fruit maturity, but had no effect on relative growth rate or total vegetative or reproductive yield. Napropamide at 4.5 and 9 kg·ha-1 and metribuzin at 0.4 and 0.8 kg·ha-1 had no effect on the rate or percentage of seedling emergence, relative growth rate, or total fruit yield. Metribuzin increased the mortality of seedlings at either application rate, and at 0.8 kg·ha-1 delayed early growth and fruit maturity in the April planting. Napropamide treatments did not differ from the water control for all characteristics and environments studied. Chemical names used: 4-amino-6-tert-butyl-3(methylthio)-1,2,4-triazin-5(4H)-one (metribuzin); 2-(α-napthoxy)-N,N-diethyl propionamide (napropamide).

An experiment was conducted in the experimental field of Rajshahi University Campus (AEZ-11) to study the influence of soil moisture and NPK fertilizers on grain growth of four varieties of barley (Hordeum velgare L.). Spikelet number (SN), spike dry weight (SDW), grain number (GN), grain dry weight (GDW), spike relative growth rate (spike RGR) and grain relative growth rate (grain RGR) were observed highest in the highest level of irrigation (40 mm). The highest amount of fertilizer (120N 75P 45K) produced the highest SN, SDW, GN, GDW, spike RGR and grain RGR. BHL-3 produced the highest SN, BARI Barley -2 produced the highest spike RGR, BARI Barley -1 produced the highest grain RGR and BL-1 produced the highest SDW, GN, and GDW.

This study aimed to examine plant growth of tomato grafted onto different eggplant rootstocks. We applied a randomized block design comprising twelve treatments with three replicates. Three varieties of tomato—Cervo, Karina, and Timoty—and three rootstocks—Gelatik, EG203 line, and Solanum torvum—were selected for this study. Nongrafted tomato plants of the same varieties were used as controls. The variables recorded were the number of branches, the diameter of scions and rootstocks, root length, and root dry weight at 4, 6, 8, and 10 weeks after planting (WAT) and relative growth rate, specific leaf area, and net assimilation rate at 4, 8, and 12 WAT. Grafted tomato plants demonstrated better growth than controls. There was a significant relationship between yield, plant growth parameters, and photosynthetic organs, expressed by higher production, greater scion diameter, longer roots, and increased relative growth rate, leaf area ratio, and net assimilation rate of grafted plants, compared to the controls.

Effect Of Age

SUMMARYOptimum transplanting age and relative growth rate in three groups of rice varieties differed with types and maturity periods. Transplanting 52 day old seedlings reduced the shoot number, and the magnitude of reduction was higher in early than in mid-early and medium varieties. Early transplanting reduced the number of days to flowering in all three groups compared with transplanting later. Senescence was much earlier in early types transplated as 52 day old seedlings. Grain production in early types was more sensitive to late transplanting than the mid-early and medium types. Medium varieties outyielded the early and mid-early ones when transplanted at 38 days after seeding.

Days After Anthesis

SUMMARYGrain growth and final weight per grain were measured in 12 genotypes of spring barley, the parents and progeny of two six-row × two-row crosses. Weight of carpels or grains from node 10 on the main shoot ear was measured from shortly after meiosis until grains were at maximum dry weight. Similar measurements were made at representative node positions along the ear of Proctor and of Midas spring barley cultivars.From about 10 days after anthesis grains grew at a constant rate for about 3 weeks. Amongst genotypes growth rate of the median grain ranged from 1·4 to 2'2 mg/day and there was a very highly significant positive correlation between growth rate and final grain weight. A similar relationship was found among grain positions on the ear. For about 10 days after anthesis growth was exponential and although relative growth rate did not differ between genotypes or grain positions there was a highly significant difference between caryopsis weights during this phase. There were significant correlations between final grain weight and carpel weight at anthesis and between final grain weight and husk weight at anthesis. In the period between meiosis and anthesis growth was exponential and the relative growth rate did not differ between genotypes or node positions on the ear. There were significant differences between carpel weights during this phase. Carpel weight at anthesis and carpel linear dimensions at meiosis were correlated.These data suggest that the initial size of carpel is an important factor in determining growth rate and potential grain weight. Potential grain size in barley may be determined by physical limitations imposed by the lemma and palea or may be causally related to the size of the carpel. The relative size of the carpel is determined by the time of meiosis and potential size may also be affected by pre-anthesis conditions.

Effect of water deficit stress on growth and yield of three wheat (Triticum aestivum) varieties, viz. BARI Gom 25, BARI Gom 26 and Sourav was studied. Water deficit lowered the light interception at anthesis in wheat. Under water deficit condition, the highest amount of PAR interception was recorded in BARI Gom 26. The reduction of leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) were less in BARI Gom 26. Water deficit conditions lowered the SPAD values in all the three wheat varieties. BARI Gom 26 showed less reduction, while BARI Gom 25 reflected the highest reduction in SPAD value under water deficit condition. Under water deficit condition the maximum number of spikelets/spike, 1000- grain weight and HI were recorded in BARI Gom 26 and the minimum in BARI Gom 25. Under both control and water deficit conditions BARI Gom 26 gave the highest grain yield, while the lowest grain yield was obtained from BARI Gom 25.Bangladesh J. Sci.
