Abstract: The objective of this work was to evaluate the effects of fertilization with nitrogen topdressing and silicates, as well as of the use of fungicides, on the occurrence of rice blast on panicles, milling yield, and whole grains, vitreous grains, and chalky kernels in a flood-irrigated rice cultivar sensitive to the disease. Two experiments were conducted in a randomized complete block design, in a 4×4×2 factorial arrangement, with four replicates: in experiment 1, four doses of nitrogen × four doses of calcium and magnesium silicate on soil × with and without fungicides; and, in experiment 2, four doses of nitrogen × four doses of potassium silicate applied on leaves x with and without fungicides. At the doses above 60 kg ha-1 nitrogen without fungicides, there was an increase of rice blast severity on panicles, a decrease in the percentage of whole and vitreous grains, and an increase in chalky kernels and chalky area. The greatest effects of silicates occurred without fungicides. Fungicide use reduced the severity of rice blast on panicles. Milling yield ranged from 60 to 70% in both experiments. The control of rice blast with fungicides maintains high rice grain quality, milling yield, and percentages of whole and vitreous grains.

An experiment was conducted in the research field of Pulses Research Sub-Station, BARI, Gazipur during two consecutive years of 2015-16 and 2016-17 to determine the suitable dose of potassium for achieving higher yield attributes, nodulation, nutrient concentration and yield maximization of lentil. There were 5 treatments viz. T1 = Control, T2 = 30 kg K ha-1, T3= 40 kg K ha-1, T4= 50 kg K ha-1 and T5= 60 kg K ha-1 along with the blanket dose of fertilizers of N, P, S, Zn and B @ 15, 20, 10, 2 and 1.5 kg ha-1, respectively for all treatments. The experiment was laid out in randomized complete block design (RCBD) with three replications. Results revealed that the highest seed yield (1092 kg ha-1) of lentil (mean of two years) was found in T4 followed by T5 treatment and the lowest (736 kg ha-1) was noted in K control (T1) treatment. The highest % yield increase over control (48.3%) was recorded from T4 treatment. The maximum nodulation was found in T5 followed by T4 treatment. The highest protein (26.9%), N, P, K, S, Zn and B concentrations of lentil seed were recorded in T4 treatment. Therefore, the results suggest that the appliction of 50 kg K ha-1 along with N15P20S10Zn2B1.5 kg ha-1 are optimum for achieving higher yield potential of lentil in terrace soils of Bangladesh.

Abstract Rice is the staple food for millions of people of Indonesia which produced from many agroecology including tidal-swamp. The contribution of swampland to the national rice production is still lower than 2%. One of the indigenous knowledge of the tidal-swamp farmers is the massive use of local varieties which have low yield. Therefore, efforts to increase rice production in tidal-swampland of Barito Kuala Regency should consider the use of superior varieties. The purpose of this study was to find out performance of seven superior varieties in tidal-swamp land in two planting seasons. This research was conducted from March 2020 to March 2021 in Karang Buah Village of Belawang District of Barito Kuala Regency, South Kalimantan Province. The research was arranged in two factors of Randomized Complete Block Design namely varieties and seasons. The first factor consisted of seven varieties: Inpari-42 (V1), Inpari-43 (V2), Inpari IR Nutri Zinc (V3), Inpara-8 (V4), Inpara-9 (V5), Inpara-10 (V6), and IR-42 (V7). The second factor, season consisted of season-1 which started from March to July 2020 and season-2 for planting period from November 2020 to March 2021. The result showed that swamp rice varieties had higher value for plant height variables than those of irrigated rice varieties with Inpari-8 as the highest one. However, all irrigated rice varieties performed better which had higher value for panicle number, filled rice grain, and yield with IR-42 as the highest one. All varieties except IR-42 showed higher values of filled grain numbers when cultivated in season-1 supported by good weather during the study.

Determination of tolerance threshold of golden snail (Pomacea canaliculata) infestation in irrigated rice had been studied at Sumbersari Village, Moyudan District, Sleman Regency, Yogyakarta Special Teritory, in the growing season of June to October 2016. The water depth during the experiment was maintained at  1 cm. The snails of 2−3 cm in length were infested on rice plots at various ages. The snails were infested on rice plots with density rates of (1) 0, 1, 2, 3, 5, 15, 30, (2) 0, 2, 3, 5, 10, 15, 30, and (3) 0, 3, 5, 10, 15, 20, 30  individuals/m2  at (1) 0 day after planting (DAP), (2) 7 and 14 DAP, and (3) 28 DAP, respectively. These treatments were replicated three times and arranged in the randomized complete block design (RCBD). In this study the tolerance threshold is defined as the highest snail density which causes no significant effect on rice damage and yield loss as compared to control or to the lowest snail density. Therefore, determination of the tolerance threshold was based on the significant difference of damage severity, panicle number per hill, and harvesting dry-weight of rice grain. Results showed that significant rice damage occurred on age of 0, 7, and 14 DAP olds, while on age of 21 and 28 DAP the rice showed no damage. More severe damage occurred to the younger rice. The tolerance threshold values of the snail on rice plots with 1 cm water depth at 0 DAP old was approximately 2 individuals/m2 while at age of 7 and 14 DAP were approximately 3 individuals/m2, respectively. IntisariPenentuan ambang toleransi serangan keong emas (Pomacea canaliculata) pada padi sawah telah dikaji di Desa Sumbersari, Kecamatan Moyudan, Kabupaten Sleman, Daerah Istimewa Yogyakarta dalam musim tanam Juni–Oktober 2016. Kedalaman air selama percobaan berlangsung dikondisikan sedalam 1 cm. Keong berukuran 2−3 cm diinfestasikan pada berbagai umur padi. Keong dengan kepadatan (1) 0, 1, 2, 3, 5, 15, 30; (2) 0, 2, 3, 5, 10, 15, 30; dan (3) 0, 3, 5, 10, 15, 20, 30 ekor/m2 diinfestasikan berturut-turut pada plot padi (1) saat tanam (0 hari setelah tanaman (HST)), (2) umur 7 dan 14 HST, dan (3) serta umur 21, dan 28 HST. Perlakuan diulang tiga kali dan diatur dalam rancangan randomized complete block design (RCBD). Dalam penelitian ini ambang toleransi didefinisikan sebagai kepadatan keong tertinggi yang menyebabkan kerusakan tanaman padi dan kehilangan hasil tidak berbeda signifikan dengan kontrol atau dengan kepadatan populasi terendah. Oleh karena itu nilai ambang toleranasi ditentukan berdasarkan signifikansi perbedaan kerusakan tanaman, jumlah bulir per rumpun, dan berat kering panen gabah. Hasil kajian menunjukkan bahwa kerusakan signifikan terjadi pada padi umur 0, 7, dan 14 hari setelah tanam (HST), sedangkan pada umur 21 dan 28 HST padi tidak menunjukkan kerusakan. Kerusakan semakin parah pada padi semakin muda. Pada kondisi kedalaman air 1 cm, nilai ambang toleransi keong mas pada padi umur 0 HST sekitar 2 ekor/m2 sedangkan pada umur 7 dan 14 HST sekitar 3 ekor/m2.

Products with physiological effects on plants to optimize agricultural production is increasingly used; they can change the development of plants and the chemical characteristics of seeds. The objective of this work was to evaluate the development of soybean cultivars and the protein and oil contents of soybean grains after treatment with pyraclostrobin and biostimulant. The experiment was carried out with soybean crops without irrigation. The experimental design was a randomized complete block design, with five replications, using a 3 × 3 factorial arrangement consisting of three cultivars of different maturation times (very early, M6952IPRO; early M7739IPRO; and medium, ST797IPRO), and three treatments with products that cause physiological effects (control, pyraclostrobin, and control + biostimulant). The pod, leaf, and stem dry weights, number of pods, 100-grain weight, grain yield, and oil and protein contents of the soybean plants were evaluated. The data were subjected to analysis of variance, and Tukey’s test at 5% probability. The effects of the products used (pyraclostrobin and biostimulant) vary according to the cultivar and may increase the soybean leaf and pod dry weights, and grain protein contents.

The work shows that application of increased doses of nitrogen does not significantly affect the total milling yield and affects the head rice content. The ambiguous nature of the variability of the grain quality of rice varieties under conditions of different doses of nitrogen fertilizers confirms the need for further studies of the varietal reaction to the level of nitrogen nutrition, based on it - the development of rice cultivation technology modes in order to obtain rice yield with high grain quality.

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

ABSTRACT: This study aimed to evaluate the control of globe fringerush (Fimbristylis miliacea ) and selectivity to rice crop irrigated with an in-tank mixture of bispyribac-sodium + metsulfuron-methyl associated with adjuvants. The experiment was conducted in the municipality of Douradina, Paraná state, Brazil (23º12'32.0" South, 53º17'39.9" West), in the agricultural year of 2012/2013. An experimental randomized complete block design with ten treatments and four replications was used. The treatments consisted of applying an in-tank mixture of the herbicides bispyribac-sodium + metsulfuron-methyl at two doses (32+1.3 and 40+3.3 g ai ha-1) associated with the adjuvants Iharaguen(tm) (375 mL.ha-1), Orobor N1(tm) (75 mL.ha-1), LI 700(tm) (150 mL.ha-1) and TA 35(tm) (50 mL.ha-1), as well as weeded and unweeded control. Although the effectiveness of globe fringerush (F. miliacea ) control with the in-tank mixture of the herbicides bispyribac-sodium + metsulfuron-methyl associated with Iharaguen(tm) and Orobor N1(tm) has been significantly higher than the effectiveness of these herbicides associated with LI 700(tm) and TA 35(tm), there were no significant differences among the treatments in terms of selectivity and grains yield of the rice cultivar Epagri 108.

The efficiency and responsiveness agronomic to the main macronutrients is becoming increasingly important due to the risk of supply, since it is a finite resource. In addition, excess fertilizer decreases the quality of water and air. Thus, the objective of this work was to assess the corn hybrids in terms of their efficiency and responsiveness to nitrogen (N), phosphorus (P) and potassium (K), and identify the ones most suitable for fresh consumption, according to the product type and technological level to be adopted by the farmer. The randomized complete block design in a 10 × 3 (hybrids and doses) factorial scheme was adopted for the experiment, with three replications, for two season crops (2013/14 and 2014/15). Ten hybrids (2B512PW, 2B587PW, 2B707PW, 30F35HR, 30F53YH, AG1051, BRS1055, BM3061, P3646H e P3862YH) were used in isolation under low availability (without application) and partial, of N, P and K, in an isolated manner, also evaluated under the recommended dose, aiming at fresh consumption. The most efficient and responsive hybrid must first be identified in isolation, based on the availability it is subjected to and later, by its sale, focused on fresh consumption. The hybrids indicated for low availability (low technological level) were BRS1055 and 30F53YH, with respect to responsiveness or agronomic efficiency, the hybrid P3862YH was the one that presented the best performance and indicated for technological levels of medium to high, considering the classification obtained for the nitrogen, phosphorus, and potassium for production vegetable corn.

Reducing productivity, outbreak of insects and diseases, and decreasingin physical and cup quality are major problems for Arabica coffee cultivation inmedium altitude. The aim of this study was to investigate the effect of altitude onphysical quality in eight genotypes of Arabica coffee. This research was conductedat two locations i.e. Andungsari Research Station-Bondowoso (1250 m asl. ashigh altitude) and Kalibendo Estate-Banyuwangi (700 m asl. as medium altitude).Randomized complete block design was used with three replications. Collecteddata consisted of outturn, weight of 100 beans, shape bean normality, apparentswelling, bulk density before and after roasting. Combined analysis on the physicalquality traits of green bean showed genotype x altitude interactions on weight of100 beans, percentage of normal beans and percentage of empty bean. Altitudesignificantly influenced coffee outturn. Decreasing in altitude from 1.250 m asl.to 700 m asl. caused declining in the outturn as much 32.9%. BP 700A, K 29, K34, K 79, and K 99 were genotypes that stable to produce normal bean and emptybeans at high and medium altidute, while K 8, K 130, and SIG were genotypeswith high normal beans at high altitude but not stable. Genotype x altitude interactiondid not occur for physical quality of other variables of outturn, bulk densitybefore and after roasting, apparent swelling, percentage of round beans,percentage of elephant beans, and percentage of triage beans. Altitude showedsignificant effect on all of physical quality of bean variables.

Abstract Most potato farmers in Indonesia select the small tubers at harvest for planting in the following season, the so-called farmers’ practice (FP). This propagation method is cheap, but the small tubers may come from less healthy plants, which increases the build-up of diseases with accelerated yield decreases over the seasons. Alternatively, farmers may identify healthy plants within the growing season and select those for propagation, the so-called positive plant selection method (PPSM). An experiment was carried out to evaluate the effects of PPSM compared to FP on yields in the following season in the two main potato growing areas of West Java, i.e., Pangalengan and Garut. Generations G2 and G3 of cv. Granola and one generation of the imported cv. Atlantic were used. Selected seeds using PPSM and FP were planted in the second season in a randomized complete block design. Results show that yields of seeds selected through PPSM were significantly higher compared to seeds selected through FP, over both locations, on average, 7.4, 5.5 and 1.2 ton ha−1 for Granola G2 and G3, and the Atlantic, respectively. These yield increases represent an increase in the gross revenue of 30.8 to 51.8 million IDR ha−1 for Granola and 1.9 to 7.8 million IDR ha−1 for Atlantic at a farm gate price of 7,000 and 6,500 IDR kg−1, respectively. This study confirms that PPSM is superior to FP and improves the quality of the farms saved seeds.
