“…As was reflected in its additive effect on proline accumulations, Si altered the biochemical composition of potato tissues making the plant more resistant to heat stress under water deficit conditions. This is in agreement with the previous work, which demonstrated the role of proline in offsetting the adverse effects of water deficit thereby conferring stress tolerance (Sapre and Vakharia, 2016). Other studies have verified that proline concentrations in potato leaves increase with increase in Si concentrations under waterdeficit conditions, which indicates that silicon may be associated with plant osmotic adjustment (Crusciol et al, 2009;Farhad et al, 2011;Pilon et al, 2014).…”

A large portion of sub-Saharan Africa is situated in belts of uncertain rainfall and are characterized by low soil fertility with limited capacity to adapt to and mitigate the impacts of climate change. A field study was conducted in the semi-humid potato-growing belt of Kenya to test the effect of legume intercropping and water soluble silicon (orthocilicic acid) on soil erosion, and use efficiency of light and water. Potato (Solanum tuberosum L.) was grown singly and intercropped with dolichos (Lablab purpureus L.) or hairy vetch (Vicia sativa L.). Each cropping system was subjected to granular water-soluble silicon (Si) amendment at two rates [2.5 kg Si ha −1 (+Si) vs. 0 kg Si ha −1 (-Si)]. Plants receiving Si maintained significantly higher (p < 0.05) percent relative leaf water content (62-89% vs. 52-72% in controls) and exhibited higher concentrations of proline (1.99-2.91 vs. 1-1.19 umol g −1), soluble carbohydrates (28-59 vs. 10-28 umol g −1) and electrolyte conductance (1,409-3,903 vs. 746-2,307 mS cm −1). Legume intercropping enhanced groundcover establishment and reduced soil and nutrient losses by 45-80% compared with sole potato. Crop yields were 2-3-fold greater in intercropping relative to sole potato and were significantly greater in treatments subjected to Si application. Land equivalent ratios were above unity in intercropping but less than unity in sole potato, and were 8-20% increased by Si application. Use efficiency of water (5.99-9.09 Kg ha −1 m −3) and light (1.98-2.98 g MJ −1) were significantly greater under legume intercropping compared with sole potato (1.13-3.23 Kg ha −1 m −3 and 0.77-0.98 g MJ −1 , respectively) and increased with Si application. Integrative use of Si and legume intercropping presents the smallholder farmers an opportunity to increase productivity of potato while enhancing resource use efficiency and soil fertility in the semi-humid tropics.

“…The data indicate that the reduction of NPK fertilizer dosages up to 50% did not significantly affect the growth performances of Detam-1 black soybean. These evidences confirm the assumption that Si promotes a healthy plant especially in combating water stress as reported by many researchers (Heckman, 2013;Chanchal et al 2016;Sapre and Vakharia 2016). Addition of Si did also induce the Si uptake as indicated by increasing Si leaf content.…”

Abstarct. Rice-field, during the dry season, offers promising potential as food crop production area particularly for secondary crops such as black soybean. However, rice-field have some limitations to support crop productivity economically, due to low fertilizer efficiency and/or water usage. Silicate (Si) fertilizer in the form of bio-nano ortho silicic acid (OSA) has been proven to improve yield and water use efficiency of black soybean on the upland, but not on rice field. This study aimed to determine the effects of bio-nano OSA application on yield, fertilizer and water use efficiencies of Detam-1 black soybean grown at a Bantarwaru rice-field, Indramayu, West Java. Experiment was undertaken from August to November 2018 with treatments consisting of : (i) control (P0), (ii) farmers’ standard practice (P1), (iii) P1 + 2 ton organic fertilizer ha-1 (P2), (iv) 50% P1 + 4 L bio-nano OSA ha-1 (P3), (v) 75% P1 + 4 L bio-nano OSA ha-1 (P4), and (vi) P1 + 4 L bio-nano OSA ha-1 (P5), in a randomized block design with three replications. The soil belongs to Alfisols with vertic property, i.e. cracking during the dry season. The results show that the application of bio-nano OSA was capable of improving yield of Detam-1 black soybean up to 26%, increasing water use efficiency up to 37%, and reducing NPK fertilizer dosages up to 50%. The highest yields of Detam-1 black soybean was 2.4-2.5-ton bean ha-1, achieved from the treatment of combination of 50-75% NPK fertilizer dosages and application of bio-nano OSA at 4 L ha-1 rate with optimum level of NPK dosage at 39.2%. By using bio-nano OSA and optimum dosage of NPK fertilizer, the farmer’s profit increased IDR 4,152,340 ha-1 per season compared to standard practice.Abstrak. Sawah tadah hujan pada musim kemarau menawarkan peluang yang prospektif untuk dimanfaatkan sebagai areal produksi tanaman pangan khususnya palawija seperti kedelai hitam. Namun, sawah tadah hujan secara umum memiliki masalah khusus untuk mendukung produktivitas tanaman di musim kemarau yaitu rendahnya efisiensi serapan hara dan/atau penggunaan air. Teknologi pupuk silika dalam formulasi bio-nano ortho-silicic acid (OSA) telah terbukti mampu meningkatkan hasil kedelai hitam dan efisiensi penggunaan air pada lahan tegalan tetapi tidak pada lahan sawah tadah hujan. Penelitian ini ditujukan untuk mempelajari pengaruh aplikasi pupuk Si (bio-nano OSA) terhadap produksi tanaman kedelai hitam Detam-1, efisiensi penggunaan pupuk, dan air pada sawah tadah hujan di Bantarwaru, Indramayu, Jawa Barat. Percobaan dilaksanakan di lahan petani pada bulan Agustus hingga Nopember 2018 dengan menguji perlakuan : (i) kontrol (P0), (ii) pemupukan standar petani (P1), (iii) P1 + 2 ton pupuk organik ha-1 (P2), (iv) 50% P1 + 4 L bio-nano OSA ha-1 (P3), (v) 75% P1 + 4 L bio-nano OSA ha-1 (P4), dan (vi) 100% P1 + 4 L bio-nano OSA ha-1 (P5), dalam rancangan acak kelompok dengan ulangan tiga kali. Tanah di lokasi percobaan tergolong ordo Alfisol dengan sifat vertik seperti timbulnya retakan saat musim kemarau. Hasil percobaan menunjukkan bahwa aplikasi bio-nano OSA mampu meningkatkan produksi kedelai hitam varietas Detam-1 hingga 26%, meningkatkan efisiensi penggunaan air hingga 37%, dan menghemat dosis pupuk NPK hingga 50%. Produktivitas kedelai hitam tertinggi sebesar 2,4–2,5 ton biji kering ha-1 diperoleh pada perlakuan kombinasi pupuk NPK 50-75% dari standar petani dan aplikasi bio-nano OSA 4 L ha-1 dengan dosis optimum pupuk NPK pada 39,2%. Tambahan keuntungan usaha tani kedelai hitam Detam-1 di Bantarwaru dengan aplikasi bio-nano OSA dan pemupukan NPK yang optimum dapat mencapai IDR. 4.152.340 ha-1 per musim jika dibandingkan perlakuan dosis pupuk standar.

“…In addition, silicon plays a role as a mechanical and a physiological barrier. It also alters the levels of osmolytes and antioxidant enzymes which are the first line of defense in drought stress, also reducing the levels of oxidative stress factors such as hydrogen peroxide (Sapre and Vakharia, 2016). These results are harmony with those obtained with Abd El-Gawad et al (2017) on potato they showed that irrigation after the depletion of 55-60 % of available soil water and spraying with potassium silicate at 2000 ppm gave the highest values of leaf area, fresh and dry weight of shoots than other interaction treatments.…”
