Abstract Planting sorghum twice a year on dry land is constrained by the short duration of rainfall, so it requires technology to increase yields with the ratoon cropping system. The research was carried out in Agricultural Technology Research and Assessment Installation of Bajeng, Gowa, South Sulawesi from March to October 2019. The superior genotypes of sorghum were planted on marginal land as the main crop with a spacing of 75 cm x 20 cm (66,666 plants/ha). The ratoon plant used a split-split plot design. The main plot consisted of two mulches: M1=no mulch + 50% dose of main crop fertilization and M2=sorghum stover mulch + biodecomposer 1kg/ha without NPK fertilizer. The sub-plots consisted of 2 populations: P1=population of 66,666 plants/ha (1 shoot/hole), P2=133,332 ratoon plants/ha (2 shoots per hole). The sub-sub-plots consisted of 5 (five) genotypes/varieties of sorghum: V1=Numbu, V2=No.58-1, V3=No. 86.1, V4=No.103-1 and V5=No. 113-1, so that 20 treatment combinations were obtained with 3 replications. The results showed that to obtain high grain yield in ratoon cultivation in dry land, NPK fertilization (150-100-50)/ha is still necessary. The increase in population density of ratoon from 66,666 to 133,333 plants/ha significantly affected the increase in grain yield. Sorghum genotype No. 58-1, No. 86-1, No. 103-1 and No. 113-1 is technically and economically feasible to be developed in the cultivation of the double harvest ratoon system with the profit (Rp 10,989,000-12,247,500/ha) from the cultivation of sorghum once the main crop (Rp 4,003,000-4,856,000). The R/C value is 2.00-2.10 and the MBCR value is 2.27-2.38.

<p><em>Mountain microorganism</em> (MM) merupakan kumpulan dari berbagai mikrobe menguntungkan yang ditemukan pada tanah yang masih virgin pada serasah yang ada di pegunungan. Tujuan penelitian ini adalah mengetahui efikasi MM sebagai bioactivator, biofermented, dan biopestisida untuk meningkatkan hasil cabai dengan menggunakan teknologi LEISA. Penelitian dilaksanakan di Ciamis, Jawa Barat mulai bulan Mei sampai dengan bulan Desember 2016. Rancangan penelitian yang digunakan adalah Rancangan Petak terpisah dengan empat ulangan. Faktor utama adalah pengelolaan hara (a = kompos + EM4) dan (a = kompos + MM + BF) 12. Subplot adalah dosis NPK (b = 1.000 kg/ha NPKdan b = 625 kg/ha NPK), dan sub-subplot adalah cara pengendalian OPT (c1= 12 konvensional dan c2 = biopestisida MM). Hasil penelitian menunjukkan bahwa pemberian MM pada kompos dapat meningkatkan pertumbuhan (tinggi dan lebar kanopi) tanaman cabai sebesar 2 – 8 cm, dapat meningkatkan jumlah buah, jumlah bunga, jumlah cabang, dan bobot buah serta mampu meningkatkan produktivitas cabai sebesar 7,20% hingga 12,5%. Pemberian kompos + MM dapat memperbaiki kesuburan kimia, sifat fisiko-kimia dan biologi tanah sehingga lebih sesuai untuk budidaya tanaman cabai merah. Pengurangan pupuk NPK sebanyak 37,5% tidak memberikan pengaruh yang nyata terhadap peningkatan produktivitas cabai merah dan komponen hasil lainnya. Penggunaan MM sebagai biopestisida dapat menghambat perkembangan OPT dengan efikasi setara dengan penggunaan insektisida sintetik.</p><p><strong>Keywords</strong></p><p>Mikroorganisme pegunungan (MM); Pupuk kimia;, Biopestisida; Cabai; LEISA</p><p><strong>Abstract</strong></p><p>Mountain microorganism (MM) is a collection of various beneficial microorganism that was found in virgin soils or forest decomposing organic matter, used in the preparation of bokashi, bioferments, and biopesticides.

Swampland plays a critical function in agriculture, specifically in growing rice production. The study aimed to determine the effects of cropping systems and varieties on the rice growth and yield in acid sulfate soil of tidal swampland. The experiment was conducted in a potential acid sulphate soils in Kapuas Regency, Central Kalimantan Province. The experiment was arranged in a split plot design with three replications. The main plot consisted of three HYV’s of rice, namely Inpara 8, Inpari 32, and Margasari. The subplot consisted of five cropping systems, namely, Jarwo 2:1A, Jarwo 2:1B, Jarwo 2:1C, Hazton, and Tegel.  The plot size was 4 m x 5 m. The variables observed included initial soil properties, plant growth, and yield components. The jajar legowo cropping system in this study was not able to increase rice yields in acid sulphate soil.  There was an interaction effect of cropping systems and varieties on the plant height and number of tillers at vegetative phase. At generative and pre-harvest phases, there was significant single effect of variety and cropping system in the planting height and number of tillers, respectively. Both cropping system and variety significantly affected the number of panicles per hill, while panicle length, grain per panicle and grain yield were only affected by variety.  There was no significant effect of both factors on the number of filled grains per panicle.  Inpara 8 variety achieved the highest grain yield, which was 6.78 ton.ha-1 or equivalent to 4.34 ton.ha-1 of 14 % water content.

The intercropping method is one way to maximize plants and soil's utilization in a dry land. This study aimed to determine the cultivation (cropping methods and fertilization) that could increase mungbean grain yield in dry land in the dry climate of East Sumba, East Nusa Tenggara Province. The experiment was conducted at dry land in a dry climate in Laipori Village, Pandawai District, East Sumba Regency in 2017. The experiment was laid out in a split-plot design with four replications. The main plot was a cropping pattern, namely (1) intercropping mungbean with maize. Mungbean plant spacing was 30 cm ´ 20 cm, two plants per hole, and maize plant spacing was (50 cm ´ 50 cm) ´ 120 cm, one plant/hole and (2) mungbean monoculture with a plant spacing of 40 cm ´ 10 cm, two plants/hole. The subplot was dosage and type of fertilizer, namely (1) 150 kg Phonska/ha, (2) 5000 kg cow manure/ha, and (3) 75 kg Phonska + 2500 kg cow manure/ha. The mungbean variety used was Vima 1, and the maize variety was Bima. The results showed that intercropping mungbean with maize could increase the yield of mungbean seeds yield by 0,28 t/ha (51,85%) and increase the mungbean biomass by 0,31 t/ha (22,30%) compared to the monoculture system. Different types and dosages of Phonska inorganic fertilizer and cow manure did not cause differences in the mungbean yield.

Chickpea is a key crop in sustainable cropping systems and for its nutritional value. Studies on agronomic and genetic influences on chickpea protein composition are missing. In order to obtain a deep insight into the genetic response of chickpeas to management in relation to agronomic and quality traits, a two-year field trial was carried out with eight chickpea genotypes under an organic and conventional cropping system. Protein composition was assessed by SDS-PAGE in relation to the main fractions (vicilin, convicilin, legumin, lectin, 2s-albumin). Crop response was highly influenced by year and presumably also by management, with a −50% decrease in grain yield under organic farming, mainly due to a reduction in seed number per m2. No effect of crop management was observed on protein content, despite significant differences in terms of protein composition. The ratio between the major globulins, 7s vicilin and 11s legumin, showed a negative relationship with grain yield and was found to be higher under organic farming. Among genotypes, black-seed Nero Senise was characterized by the highest productivity and water-holding capacity, associated with low lectin content. These findings highlight the importance of the choice of chickpea genotypes for cultivation under organic farming in relation to both agronomic performance and technological and health quality.

The effects of two tillage methods (zero tillage and conventional tillage), two residue managements (residue kept and residue removed) and two levels of cropping system (maize + soybean and sole maize) were studied over 3 years (2015-2017) at Dailekh district of Nepal. Arun-2 and Puja were the varieties of maize and soybean used respectively, followed by winter wheat. The results revealed that the maize + soybean system had significantly higher plant population and ear population (34.83 thousands ha-1 and 34.35 thousands ha-1, respectively), grains per row (37.1), ear length (16.6 cm) and 20.5% higher grain yield as compared to sole maize. The highest maize equivalent yield (7.92 t ha-1) was recorded in maize + soybean as compared to the lower grain yield equivalent (7.06 t ha-1) in sole maize. Zero tillage accounted relatively higher benefits (high net income and B:C ratio) as compared to conventional tillage. The residue kept plot resulted significantly higher B:C ratio (2.41) than the residue removed (2.11) and the maize + soybean recorded 82.5% greater B:C ratio compared to sole maize. Net annual income was significantly higher in zero tillage, residue kept and maize + soybean system (NRs. 223072.00, 222958.00 and 269016.00 ha-1 respectively). Such combinations are recommended for Dailekh district of Nepal to have profitable crop productivity. SAARC J. Agri., 17(1): 49-63 (2019)

The research work conducted at the Teaching and Research Farm of University of Abuja was aimed at assessing the effect of Moringa oleifera, selected leguminous plants and inorganic fertilizer on the performance of orange fleshed sweet potato in Alley Cropping System. Randomized Complete Block Design (RCBD) using five treatments with three replications was applied. Data collected include: percentage survival of sweet potato, length per vine (cm), number of leaves per vine, leaf area of sweet potato, weed dry matter (g/m2), yield of sweet potato roots. Highest number of leaves (28) per plant was recorded in the control plot while the plots with NPK fertilizer had the highest length per vine (94.55cm) though not significantly (p>0.05) different from others. Higher percent survival (88%) of sweet potato was recorded from control plots. Stands grown in Arachis hypogeae plots produced the highest leaf area (0.202m2) while plots in which NPK fertilizer was applied experienced highest weed dry matter (4.083g/m2) although highest root yield (1.2t/ha) was recorded from the plots with NPK fertilizer.
