<em>Zinc deficiency (Zn) in tea </em>[Camellia sinensis<em> (L.) O. Kuntze</em>] <em>may inhibit growth and decreases shoots production. To overcome the deficiency, zinc is generally given in the form of zinc sulphate fertilizer (Zn 22.75%) through foliar application. Today there is a micro-fertilizer with a higher zinc consentration (Zn-30%). The research aimed to determine the effect of dosage and application interval of Zn-30% micro fertilizer on production and yield component of tea shoot. The experiment was conducted in Pasirmalang Estate, Afdeling Wetan Block Pakurendeng II, PT Perkebunan Nusantara VIII Pangalengan Bandung, West Java, altitude ±1,600 m asl, from November 2016 to June 2017. The tea clone used was productive GMB 7. Experiments were designed by randomized block design with 2 factors and 4 replications. The first factor is Zn-30% that consisted of 4 levels i.e. Zn-30% with a dose of 300, 250, and 200 g/ha respectively, and  ZnSO<sub>4</sub> with a dose of 2 kg as control. The second factor is interval of application that consisted of 2 levels, once and twice applications after plucking. Variables observed were production and yield components of tea shoot. The results showed that application of Zn-30% with a dose of 300 g/ha in one time interval of application after plucking effectively increased shoot production compared to other doses, but not significantly different with </em><em>ZnSO<sub>4</sub> in two time interval of application. Application of Zn, either in the form of oxide salt or zinc sulphate, increased the percentage of pecco shoots and reduces number of banji shoots.</em>

In order to investigate the effect of seed sowing date and humic acid foliar application on some agronomic traits of bread wheat an experiment was conducted in Islamshahr, Iran during 2013 growing season. The experimental design was a complete randomized block design arranged in factorial with three replications. The first factor was included two sowing date (middle of November and middle of December) and the second factor was included three humic acid levels (0, 4 and 8 liter ha-1). The results indicated that late seed sowing lead to significant reduction in agronomic traits such as tiller number, spike number, seed number and seed weight. In addition, vegetative growth was affected by late seed sowing and so that shorter plants were observed. Number of days until spike emergence, number of days until pollination and number of days until physiological maturity decreased due to late seed sowing. By contrast, humic acid application increased plant growth and improved yield and yield components through extending growing period.International Journal of Natural Sciences (2015), 5(1) 8-14

Abstract The aim of this research was to evaluate the performance of yield and yield components of soybean genotypes, as well as the relationship pattern among characters that affect the seed yield. The research material consists of 145 F5 lines and five check cultivars, which were evaluated for their yield and yield components in Malang and Probolinggo, using a randomized block design with two replicates. The combined analysis of variance for yield and yield component showed a significant interaction effect between location and genotype for the number of branches, the number of empty pods, 100 seed weight, and seed yield. The performance of yield and yield components of soybean genotypes tested in Malang showed earlier maturity, taller plants, larger seed size, and higher seed yields when compared to research conducted in Probolinggo. In the selection for the best genotypes, ten genotypes were chosen for their large seed size criteria, while two genotypes were chosen for their relatively medium maturity (81 days) in the location of Malang. In Probolinggo, of the ten genotypes, three genotypes with medium maturity, and three genotypes with medium seed size. The selected genotypes will proceed to the stage of the advanced yield trial. The association study revealed that soybean yield has a positive correlation with plant height, number of nodes, number of branches, number of filled pods, days to flowering, and days to maturity. Those yield components could be used as selection criteria in the breeding program to obtain high-yielding soybean cultivars.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.

ABSTRACT The objective of this study was to investigate the effect of interaction between nitrogen topdressing and different application ways (active ingredients) a.i. fluazifop-p-butyl + fomesafen in weed control and agronomic performance of common bean. The experiment was conducted during winter 2003 in Selvíria/MS. The experimental design used was a randomized block design with four replications in a factorial scheme 2x7. The first factor was composed by the absence or presence of nitrogen topdressing, while the second factor consisted of different application ways of fluazifop-p-butyl + fomesafen. The following variables were measured: leaf N content, dry matter of plants, yield components (number of pods plant-1, number of grains plant-1, the average number of grains pod-1 and mass of 100 grains), grain yield, phytotoxicity and weed control percentage. The nitrogen topdressing with 75 kg ha-1provided higher dry matter of plants, higher weed control and higher common bean yield of irrigated winter. In the absence of nitrogen topdressing in the application of urea before or together to fluazifop-p-butyl + fomesafen increased their effectiveness in controlling weeds without interference in the agronomic performance of common bean.

Papaya is a popular fruit and is grown commercially in many subtropical and tropical countries. Papayas are generally grown from seeds; therefore the offsprings are not true-to-type and could come in three sexes, female, male, and hermaphrodite. Clonal propagation is required to obtain to grow true-to-type hermaphrodite papayas. In this research, we developed an in vitro protocol for shoot multiplication from lateral shoots from in vitro germinated papaya seedlings. The in vitro propagated plant materials could potentially be used as a source of papaya micro cuttings, or as scion for papaya grafting. The experiment was set up as a factorial experiment with NAA at 0, 0.1 and 0.5 mg.L-1, and BAP at 0, 0.1, 0.5, and 1.0 mg.L-1 in a completely randomized block design. BAP interacted with NAA in affecting the shoot production per explant. The optimum BAP and NAA concentration to produce lateral shoots was 0.54 mg. L-1 and 0.1 mg.L-1, respectively. Media without NAA reduced the number of lateral shoots and number of leaf per explant at any BAP concentration.Keywords: hermaphrodite, seeds, true to type, clonal propagation, micro cuttings.
