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.

Light textured acid soil with conventional culture of growing crops faces poor germination due low moisture retention with infrequently quandaries like restricted activity of salutary soil micro-organisms and ultimately poor yield. To combat these soil health problems and to ameliorate the overall productivity of northern Bengal region an experiment was done at Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, with split-split plot design having two main-plot and two subplot mulching treatments and four sub-sub plot nutrient management treatments. The observations with conservation techniques on three year studies overcome the quandaries and showed positive cognation between soil moisture and germination. Difficulty with establishment of maize and reduced yield was additionally solved with soil health benefits.

The experiment was conducted in the degraded ex-tin mining farm of Universiti Putra Malaysia during November 1998 to May 1999. The experiment was laid out in split plot design with three replications. Three phosphorus (P) rates, viz., 0, 50 and 100 g Gaphsa phosphate rock (GPR) per plant in combination with and without arbuscular mycorrhiza (AM) inoculation were studied on newly planted tree species Acacia mangium. Mycorrhiza inoculation was assigned to the main plot and P dose to the subplot. Three-month-old AM preinoculated seedlings were planted in the field at 2 m x 2 m spacing. The experiment was continued until 160 days after planting (DAP). Mycorrhiza inoculation and rate of P application significantly influenced growth and development of the A. mangium plants. The highest growth of un-inoculated A. mangium plants was observed with 100 g GPR per plant; whereas for AM inoculated plants the highest growth was observed with 50 g GPR per plant. This indicates that P requirement of newly planted A. mangium plants on degraded ex-tin mining land could be reduced to 50 g GPR per plant, i.e., by 50% with AM inoculation.

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>
