The present investigation was carried out with F2 plants from a cross between two parents i.e., BPT-5204 and IR-64Drt1. The selection of parents for crosses was made based on genotypes that were tolerant and susceptible to drought condition. BPT-5204 was drought susceptible and IR-64Drt1 was also tolerant to drought. In this experiment adequate amount of variability was detected for grain yield per plant and its components among 324 segregants evaluated under augmented randomized block design II in normal field condition. The analysis of variance for grain yield and its attributing characters among blocks, treatments, entries, checks and checks vs entries revealed presence of significant variation in the segregants studied. However, with respect to checks, non-significant differences were recorded for only L/B ratio. The results indicated that among 324 rice genotypes including checks, only 9 rice genotypes expressed higher yield compared to seven checks varieties under normal field condition. The segregants S-51, S-122, S-135, S-195, S-199, S-210, S-219, S-222, S-251 were top ranking genotypes with respect to all checks.

<br />Seed priming has been widely used to improve seedling vigor of several crops  such as corn, wheat, and rice. Seed priming with zinc to increase seedling tolerance on submergence stress had never been evaluated. The objective of this research was to identify agronomical and physiological characteristics of several rice genotypes during seedling stage at submergence stress following zinc priming treatment. This research used factorial randomized block design with three replications. The first factor was rice genotypes and second factor was zinc solution of ZnSO4.7H2O. Seeds were soaked with Zn solution at different concentrations namely 0, 2.5, dan 5.0 mM respectively for 24 hours. After that the seeds were germinated on soil media in side the plastic box. Fourteen days-old seedling were submerged in water for 5 days and then return to normal condition for recovery. Parameters being observed included seedling dry weight, shoot carbohydrate, and leaves chlorophyl which were measured after 10 days of recovery. Seedling height was measured once a week from 2nd to 4th week. Results showed that intolerant genotypes to submergence stress grew faster but seedling dry weight, shoot carbohydrate and leaves chlorophyll content were lower compared to those tolerant genotypes. Local and national varieties which were not tolerant to submergence stress could be improved by priming treatment with 5.0mM zinc.<br /><br />Keywords: abiotic-stress, seeds- priming <br /><br />

Cultivation Techniques

Soybean is an important food crop after rice and corn. Soybean production in East Kalimantan based on the 2014 forecast rate is estimated at 1,263 tons of dry seeds. Compared to 2013 production (ATAP 2013) there was a decrease of 139 tons (9.91%) (BPS, 2014). The low productivity is because the technique of managing soybean plants is still not optimal. Efforts to increase soybean productivity can be done by conducting intensive cultivation techniques. One of the cultivation techniques that can be done is by technical methods, namely crop trimming and intensive agricultural cultivation can be done in various ways including fertilization. The study was carried out for 5 months, namely from January to May 2018. The research site was on experimental land owned by the Faculty of Agriculture, Widya Gama Mahakam Samarinda. This study used a Randomized Block Design (RBD) with a 2 x 3 factorial experiment consisting of 3 replications. The first factor is Pruning which consists of 2 levels: namely p0 (without pruning), p1 (vegetative phase V4 pruning). The second factor is the dose of Solid fertilizer consists of 3 levels, namely s0 (without fertilization), s1 (5 kg / plot), s2 (10 kg / plot). The results showed that the pruning (P) treatment had a significant effect on the parameters of the number of productive branches and had no significant effect on height, flowering age, number of pods, weight of 100 seeds, weight of crop seeds and weight of mapped seeds. While giving Solid (S) fertilizer does not significantly affect all parameters. But the interaction of the treatment of pruning and giving Solid (PS) significantly affected the parameters of the number of productive branches.

Abstract. Limbongan YL, Driyunitha, Sjahril R, Riadi M, Jamaluddin I, Okasa AM, Panga NJ. 2021. Heritability and genetic advancement on agronomic characters of Toraja red rice x Inpari-4 white rice genotypes. Biodiversitas 22: 3446-3451. Determination of genetic diversity, heritability, and genetic advance on specific agronomic characters of cross-breed red rice genotypes (Toraja red rice Pare Lea’ x Inpari-4) was done in Tallunglipu, North Toraja, South Sulawesi, Indonesia. The experiment was designed using a randomized complete block design. Twenty-one days old seedlings were transplanted following the system of rice intensification practices. Selection was conducted at F2 as a novel method to speed up genetic advancement and ensure progeny production with desired agronomic traits. Results indicated existence of a considerably high level of diversity among genotypes tested, where the highest value for genetic advance was observed in filled-grain weight per hill of F2 plants (983.890), followed by plant height (335.124), and filled-grain weight per hill of F1 (306.645). The highest estimate of broad-sense heritability was recorded in 1000-grain weight (0.915), number of productive tillers (0.788), plant height (0.765), flag leaf length (0.705), filled-grain weight per hill (0.688), and harvest age (0.594). Genetic advance of agronomic characters between genotypes varied from 1.631-38%, where the highest estimate was recorded in filled-grain weight per hill (38%) and plant height (24.648%). The above-mentioned characters could be used for selection in further rice breeding programs to obtain plants with superior genotypes.

Potato is one of the world’s fourth most important food crop after rice, wheat and corn. More than one billion people consume potatoes worldwide and it is the part of the diet of half a billion people in developing countries. In terms of area, India ranks third in the world after China and Russia and second in production after China. Afield experiment on effects of different fertilizer doses on yield and its attributes on potato was conducted during Rabi season for three consecutive years with an objective to prevent the indiscriminate use of fertilizers by the potato growers. The experiment was laid out in Randomized Block Design with seven treatments and 3 replications. The results revealed that potato treated with T2= 100% RDF i.e. 150 kg N, 60 kg P2O5 and 120 kg K2O recorded a yield of 15.33 t/ha which was at par with that recorded by T3 i.e. 150% RDF (13.74 t/ha). The fertilizer dose of 100% RDF was found beneficial for improving yield, quality and storability of potato tubers. The gross monitory return (Rs. 1,83,397/ha) and net monitory return (Rs. 98,401/ ha) were found to be maximum in treatment T2. B:C ratio was found to be maximum in T2.

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.

Sixteen genotypes of rice (including one check) were evaluated on 18 quantitative traits during sali (August), 2018 in a randomized block design with three replications at Instruction cum Research Farm, Department of Plant Breeding and Genetics, Assam Agricultural University, Jorhat to study the nature and magnitude of variability, heritability and genetic advance under delayed sown condition. The analysis of variance for 18 quantitative traits revealed the presence of significant differences for grain yield and its component characters. The highest genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was observed for chaffs per panicle followed by grains per panicle, spikelet sterility (%), spikelets per panicle, grain yield (kg/ha). A high heritability coupled with high genetic advance was observed for plant height (cm), spikelets per panicle, spikelet sterility (%), chaffs per panicle, grains per panicle, grain yield (g/hill), grain yield (kg/ha), biological yield (kg/ha), straw weight (kg/ha) and harvest index (%) indicating that selection might be effective for improvement of these characters under delayed sown condition with low input. From the findings of this investigation, one genotype viz., Gandhari emerged as the outstanding genotype which yielded 4170 kg/ha and could be directly used for cultivation in delayed sown situation with low inputs. Some other promising genotypes that yielded higher than the check Manoharsali under delayed sown condition were JR 29, JR 16, Basundhara and JR 60 and could be utilized as potential parental material in the hybridization programmes designed to develop suitable rice varieties for delayed sown situation.
