A field experiment was conducted during the cropping seasons of 2017/2018 to evaluate the effect of levels of herbicide and N fertilizer and sorghum varieties on striga management in the Western Tigray. Split-split plot design was used to conduct the experiment using three replicate. The experiment comprised of four levels of N fertilizer in the main plot (control (0 kg/ha, 23, 46 and 69 kgha-1) and herbicide applications in sub-plot (0, 10, 15 and 20 gha-1) and three sorghum varieties (Birhan, Deber and Wediaker) in sub-sub plot under naturally S. hermonthica infested area. Striga counts and striga growth parameters were recorded. Results showed that days to first flowering, striga count per sorghum plant, stand counts of striga at 45 DAP, 65 DAP and 85 DAP per m-2, branch number per plant, plant height and biomass of striga were significantly (P<0.01) affected with the application of N fertilizer, herbicide rates and varieties. Generally, an integrated approach was found to be the best method to control striga.

Abstract. Mawarni L, Nisa TC, Napitupulu JA, Karyudi. 2019. Determination of leaf status of soybean varieties on shading. Biodiversitas 20: 615-620. The shading tolerant soybean varieties could be identified through the character growth such as leaf status. This study was aimed to obtain the shading tolerant of soybean variety based on their seed size and on the leaf status. Design of experiments was a split-plot design with three replications. The level of shading as the main plot with four levels of treatment was without shading, 30%, 50%, and 70% shading. Soybean varieties as the subplot had 4 genotypes namely Anjasmoro, Pangrango, Tanggamus, and Nanti wherein one variety comes with large seed; two come with medium seeds and the other one comes with small seed. The leaf status for determination was the greenness of leaves, the sum of chlorophyll a, chlorophyll b, total chlorophyll a and b, the forms of chloroplasts and leaf area. The soybean varieties with different seed sizes showed the differences only on the leaf area but not on leaf greenness or on the sum of chlorophyll. Nanti variety, having small seed, turns out to have the largest leaf area but is not shade tolerant. The large leaf area may be due to the forming of tetra foliate leaves on Nanti variety. The form of chloroplast of Anjasmoro variety in 70% shading is better than other varieties. Therefore, determining leaf status can identify shading tolerant of soybeans.

<p>Kentang merupakan sayuran yang memiliki prospek untuk mendukung program diversifikasi pangan. Akan tetapi saat ini produksi di dalam negeri masih rendah akibat penggunaan benih yang kurang bermutu. Sistem irigasi tetes berpeluang untuk diterapkan pada produksi benih kentang G0. Penelitian  bertujuan untuk mengetahui pengaruh frekuensi dan volume fertigasi terhadap produksi benih G0 kentang pada sistem irigasi tetes. Penelitian  dilaksanakan sejak bulan Mei sampai dengan September 2016 di Rumah Kassa Desa Cikahuripan, Lembang, Bandung Barat, Jawa Barat dengan ketinggian 1.200 m dpl. Percobaan menggunakan rancangan petak terpisah (split plot design) dengan rancangan acak kelompok lengkap dan tiga ulangan. Sebagai petak utama adalah frekuensi fertigasi sebanyak 3, 5, dan 7 kali. Sebagai anak petak adalah volume fertigasi (ml) setiap aplikasi, yaitu 100, 200, 300, dan 400. Hasil penelitian menunjukkan tidak terjadi interaksi antara perlakuan frekuensi dan volume fertigasi terhadap semua peubah pengamatan. Frekuensi fertigasi terbaik terhadap bobot ubi per tanaman umur 100 HST adalah lima kali, yaitu jam 7, 10, 12, 14, dan 16. Volume fertigasi terbaik terhadap jumlah ubi ukuran besar umur 100 HST adalah 300 ml per aplikasi per polibag. Volume dan frekuensi fertigasi terbaik ini diharapkan tidak saja meningkatkan produksi benih, tetapi juga keuntungan usahatani yang diperoleh. Perlu dilakukan penelitian lebih lanjut untuk menginduksi pengumbian dengan mengalihkan ukuran ubi menjadi peningkatan jumlah ubi sebagai tujuan produksi benih G0.</p><p><strong>Keywords</strong></p><p><em>Solanum</em> tuberosum L.; Irigasi tetes; Fertigasi; Frekuensi; Volume</p><p><strong>Abstract</strong></p><p>Potato is one of vegetables that can be used as an alternative to support food diversification programs. But the potato production domestically is still low because of low quality seed. One of the potato seed technologies that can be developed is arragement of fertigation volumes and frequencies on drip fertigation. The objective of this research was to determine the best fertigation volume and frequency in G0 potato seed production in drip irrigation. This research was conducted from May to September 2016 at Screen House Cikahuripan Village, Lembang, Bandung on 1,200 m asl. The treatments were arranged in split plot design with randomized complete block design and three replications. The main plot was fertigation frequency which was consisted of three levels; 3, 5, and 7 times per day. The subplot was fertigation volume which was consisted of four levels; 100, 200, 300, and 400 ml per aplication. The result showed there was no interaction between fertigation frequency and volume on all observation. The best fertigation frequency on tuber weight per plant at 100 day after planting was five  times, i.e. 7, 10, 12, 14, and 16 o’clock. The best fertigation volume on number of big tuber at 100 day after planting was 300 ml per application. The best fertigation volume and frequency will increase not only seed production, but also profit of bussiness. Next research will be done to induction tuberization by transfering measurement of tuber to increase the amount of tuber as goal of production of G0 potato seed.</p><p> </p>

Phosphorus and boron are required for growth and development of black gram, and play an important role in the uptake of other nutrients such as N and K. The availability of P and B is less in acid soil because of fixation and leaching losses. Therefore, a field experiment was conducted to investigate the influence of P and B on N and K uptake in black gram with four levels of phosphorus (0, 25, 50, 75 kg ha-1) and four levels of boron (0, 0.5, 1.0, 1.5 kg ha-1) comprising of 16 treatments. The trail was laid out in split plot design and replicated three times. Phosphorus was used as main plot and boron as sub-plot. Significantly highest nitrogen concentration in black gram seed was observed at P75B1.5 as 3.82%, whereas in straw, it was observed at P75B1 as 1.75%. However, significant nitrogen uptake by seed and straw was recorded as 43.85 and 39.55 kg ha-1 at P75B1.5, respectively. Similarly, significantly highest potassium concentration in seed and straw was observed at P75B1.5 as 1.13% and 1.64%. Significant highest uptake of K by seed and straw was recorded at P75B1.5 as 13.00 kg ha-1 and 36.86 kg ha-1, respectively. Therefore, 75 kg P2O5 and 1.5 kg B ha-1 is considered optimum for achieving higher nitrogen and potassium uptake by black gram in acid Inceptisol of Meghalaya.

ABSTRAKBeberapa tahun terakhir, para peneliti pertanian menunjukkan minat yang meningkat dalam penggunaan silikon (Si) dalam tanaman untuk yang meningkatkan ketersediaan hara (N, P, K), peningkatkan kinerja pertumbuhan dan efisiensi respons hasil, serta peningkatan toleransi terhadap tekanan biotik dan abiotik, serta toksisitas tanah Al, Fe, Mn dan garam yang berlebihan, tetapi perlu lebih banyak bukti pendukung tentang peran Si pada tanaman padi di lapang. Oleh karena itu, penelitian ini bertujuan untuk menyelidiki dampak pemberian silika alami maupun nano-Silika untuk meningkatkan kualitas hasil dan usahatani tanaman padi.Metodologi penelitian yang dilakukan adalah Rancangan Petak Terbagi Faktorial yang diulang tiga kali dengan menggunakan uji lanjut BNT 5%. Petak utama adalah Silika Alami dengan taraf: A0 (kontrol), A1 (Silika Sekam), A2 (Silika Arang Sekam), dan A3 (Silika Powder). Anak petak adalah perlakuan Nano Silikon (N) terdiri dari 4 taraf yaitu: N1 (frekuensi pemberian 1x), N2 (frekuensi pemberian 2x), N3 (frekuensi pemberian 3x), dan N4 (frekuensi pemberian 4x).Parameter pengamatan adalah: tinggi tanaman, jumlah daun per rumpun, jumlah anakan per rumpun, tingkat serangan hama utama, jumlah malai per rumpun, jumlah biji per malai, bobot gabah isi per malai, berat gabah kering giling dan hasil gabah per hektar. Sementara itu, dilakukan pula analisis usahatani yang mencakup biaya produksi tanaman padi dengan menggunakan teknologi aplikasi Si. Hasil pengamatan parameter pertumbuhan dan hasil pada tanaman secara umum menunjukkan perbedaan tidak nyata, namun pada pengaruh tunggal frekuensi pemberian 3x memberikan hasil yang terbaik. Sementara pada hasil usahatani menunjukkan bahwa pada pelaksanaan pertanian padi yang menggunakan silika memberikan keuntungan yang lebih besar dibandingkan metode konvensional. ABSTRACTSilicon application in most plants tend to show increase induced resistance, growth and productivity. However, more field experiment evidence needed to support Si as a beneficial nutrients in plants. Therefore, this study aims to investigate experimentally the effects of giving silica both natural and nano-Silica to improve the quality and yield of rice farming.The research methodology used was to use factorial split plot design which was repeated three times using a 5% LSD test. As the main plot is natural silica with levels: A0 (control), A1 (husk silica), A2 (charcoal silica), and A3 (silica powder). As subplots, nano silicon (N) treatment consists of 4 levels, namely: N1 (1x frequency), N2 (2x frequency), N3 (3x frequency), and N4 (4x frequency).Observation parameters in this study were: plant height, number of leaves per clump, number of tillers per clump, main pest attack rate, number of panicles per clump, number of seeds per panicle, weight of filled grain per panicle, weight of dried grain milled and grain yield per hectare. Meanwhile, an analysis of farming is also carried out which covers the cost of producing rice using this technology. The results of observations of growth parameters and yields on plants in general show no significant differences, but on the influence of a single frequency of 3x gives the best results. While the results of farming shows that the implementation of rice farming using silica will provide greater benefits compared to conventional methods.

An experiment was conducted in split plot design with three replications to determine the optimum date of sowing for commercial cultivation of cucumber at Lamjung Campus, Sundarbazar (750 m asl), Lamjung during December 1999 to November 2000. The cvs. Green Long and Bhaktapur Local were used in the main plot and the sowing dates in the sub-plot. Sowings were done on the 15th of the months December 1999 and February, April, June and August 2000 at an interval of two months. Manure and fertilizers were applied @ 20 t farm yard manure and 120:60:50 NPK kg/ha in all the sowings. Yield attributing characters such as plant stand, vine growth, first male and first female flowers bearing nodes, number of female flowers per plot, sex ratio and number of harvests were insignificantly different in December and February sowings. However, the periods of phenophases such as sowing to the first male and first female flowers and sowing to first harvest and last harvest were significantly longer at December sowing followed by those at February sowing. The three latter sowings showed poor performance in respect to those characters. February sowing produced significantly the highest number of marketable fruits (79.16 thousand/ha) and marketable yield (53.97 t/ha) than the earlier December and three latter sowings. The December sowing also produced significantly higher marketable yield (23.76 t/ha) than June and August sowings. Hence, the cvs. Green Long and Bhaktapur Local could not produce economic yields at April, June and August sowings at Sundarbazar (middle hill) Lamjung. Key words: Cucumber cultivar, sowing date, marketable yield J. Inst. Agric. Anim. Sci. 26:163-166 (2005)

Nitrogen merupakan unsur hara esensial tanaman yang diperlukan paling banyak dibandingkan unsur hara lainnya. Namun demikian, pemberian pupuk N secara terus menerus berdampak pada menurunnya daya dukung lahan. Zeolit yang dapat digunakan untuk mengefisiensikan penyerapan N. Penelitian bertujuan untuk mengkaji dampak pemberian zeolit pada berbagai taraf pemberian N pada tanaman sorgum dilakukan dari bulan April hingga Juli 2017 di lahan sawah Desa Sumberduren, Kabupaten Kediri, menggunakan Rancangan Petak Terpisah dengan menempatkan dosis pupuk N (50%, 100% dan 150%) pada petak utama, dan dosis zeolit (0%, 50%, 100% dan 150%) pada anak petak yang diulang 3 kali. Ada tidaknya interaksi atau pengaruh nyata menggunakan Uji F taraf 5% dan dilanjutkan Uji BNJ taraf 5% untuk mengetahui perbedaan diantara perlakuan. Hasil penelitian menunjukkan dosis N 50% pada zeolite 150% mendapatkan hasil biji sorghum sebesar 3,32 t ha-1. Adapun dosis N 100% dan 150 % mengurangi penggunaan zeolite sebesar 43,5% dan 48,12% dengan hasil biji sorghum sebanyak 4,56 t ha-1 dan 5,15 t ha-1. Aplikasi 50% dan 100% zeolit dapat menekan penggunaan N sebesar 13,67% dan 16,19%.ABSTRACTNitrogen is an essential nutrient and needed in the highest amount compared to other elements. However, the continuous use of nitrogen  causes a decrease in the carrying capacity of the land. Therefore to anticipate these problems, zeolite applications is prior to be done. The study aimed to assess the effect of N and zeolite application on sorghum plants which had been carried out from April to July 2017 in paddy fields in Sumberduren Village, Kediri Regency. Split Plot Design was used in this study by placing N fertilizer doses (50%, 100% and 150%) as the main plot, and zeolite dosage (0%, 50%, 100% and 150%) on subplots repeated 3 times. F test at 5% was used to determine the effect of treatments, while the average difference between treatments were referred to HSD value at 5%. The using of 100% and 150% N dosages could reduce the zeolite usage about 43.5% and 48.12% with sorghum yield as much as 4.56 t ha‐1 and 5.15 t ha-1 respectively. However, with the application of 50% and 100% zeolite, it can reduce N use by 13.67% and 16.19%.

Field trials were conducted during 2011 and 2012 cropping seasons at the Teaching and Research Farm of Federal College of Horticulture Dadinkowa in Sudan savanna agro-ecological zone of Nigeria. The objectives of the trial were; to determine the effects of farmyard manure and integrated weed management on okra growth. The treatments were laid out in a split-plot design with farmyard manure rates occupying the main plots; while integrated weed management rates were allocated to the sub-plots and replicated three times. Farmyard manure was applied to affected plots a week before sowing okra, while pendimethalin 500 EC was applied pre-emergence at the rate of 2.5 kg a.i. ha-1 immediately after sowing. Results revealed that the effects of farmyard manure and integrated weed management were significant on plant height (P≤5%), number of leaves plant-1, number of branches plant-1 and leaf area plant-1. It was observed that the control treatments of no farmyard manure applied and no weed control significantly gave lower means on okra growth parameters, while application of 4 t ha-1 of farmyard manure and weeding once at 2 + 4 + 6 + 8 WAS together with 2.5 kg a.i. ha-1 of pendimethalin 500 EC significantly gave higher means on the same traits, as well as integrated weed management.
