Increasing of maize productivity can be reched through using of superior varieties BISI 18, aplication of organic fertilizer, and regulation of crop populations. This study was aimed to know the influence of jajar legowo planting system (2:1) and cow manure on growth and yield of maize. This research was conducted in Bualemo B, Bualemo, Banggai from July up to October 2020. The experiment was arranged in Randomized Block Design with 2 factors, the first factor is the spacing of planting in legowo planting system (2:1), which consists of 3 levels namely 70 x 25 x 25 cm (J1), 70 x 30 x 30 cm (J2), 70 x 35 x 35 cm (J3), the second factor is the dose of manure which consists of 3 levels namely 8 tons/ha (K1), 9 tons/ha (K2), and 10 tons/ha (K3). Each treatment had 3 replications so there were 27 treatment plots. The results showed that the combination of jajar legowo planting system and cow manure has no effect on the height of plants at 2, 4, and 6 weeks after planting, as well as the number of leaves, but giving the effect on the height of plants at 8 weeks after planting. The combination of jajar legowo planting system and cow manure has a real effect on the average weight of cob and has a very real effect on dry weight per plot. The  weight average in corn cobs about 239.67 grams in the spacing of planting 70 x 35 x 35 cm with 8 tons/ha dose of manure. While the grain dry weight average is highest in the spacing of planting 70 x 35 x 35 cm with 10 tons/ha dose of manure and it is about  212.56 ounces.

Sistem tanam (ST) yang sering digunakan petani yaitu ST tegel. Sampai sekarang masih banyak petani yang menggunakan bibit lebih dari tujuh batang per lubang tanam (BpLT). Tujuan penelitian adalah untuk mempelajari respon tanaman padi terhadap  ST dan jumlah bibit per lubang tanam (JBpLT). Penelitian dilakukan di Desa Raman Aji, Kecamatan Raman Utara, Lampung Timur pada bulan Februari sampai Mei 2016.  Perlakuan disusun dalam Rancangan Kelompok Teracak Lengkap dengan pola split plot.  Petak utama adalah ST jarwo 2:1, ST Jarwo 4:1, dan ST tegel 25 x 25 cm. Anak petak terdiri atas JBpLT: 1 BpLT, 2 BpLT, dan 3 BpLT. Data dianalisis ragam dan dilanjutkan uji orthogonal  kontras, semua pengujian dilakukan pada taraf 5%.  Hasil percobaan menunjukkan bahwa (1) ST jarwo 2:1 dan ST jarwo 4:1 meningkatkan pertumbuhan padi hibrida Mapan P-05 dibandingkan ST tegel 25 x 25 cm, (2) penanaman 1 BpLT meningkatkan komponen hasil padi dibandingkan penanaman 2 BpLT dan 3 BpLT, dan (3) penanaman 1 BpLT memberikan hasil GKG (6,86 t ha-1) yang lebih tinggi dari penanaman 2 BpLT (5,64 t ha-1) dan 3 BpLT (4,59 t ha-1) pada ST jarwo 2:1, ST jarwo 4:1 dan ST tegel 25 x 25 cm, secara berurutan.AbstractThe common planting system (PS) used by the farmers is Tegel system. Yet, many farmers still use more than seven seeds per planting hole (SpPH). The research objective was to study the reponse of rice plants to the planting system and the number SpPH. The research was conducted in Raman Aji Village, Raman Utara, East Lampung from February to May 2016. The treatments were arranged in a RCBD with a split plot pattern (the main plot were the PS i.e. jarwo 2: 1, jarwo 4: 1 and “Tegel” 25 x 25 cm; the subplots are the number of SpPH i.e. 1 SpPH, 2 SpPH, and 3 SpPH). The results showed that (1) the jarwo 2: 1 system increased rice growth compared to the 25 x 25 cm “Tegel”; (2) application of 1 SpPH increased the yield  component  of rice compared to planting 2 SpPH and SpPH; and (3) application of 1 SpPH (6.86 t ha-1) gave the higher weight of milled grain than using 2 SpPH (5.64 t ha-1) and 3 SpPH (4.59 t ha-1), both planted in the jarwo 2:1, jarwo 4:1 and 25 x 25 cm  “Tegel” System

Waterlogging was one of the main abiotic stresses affecting maize yield and growth in the North China Plain, while ridge tillage effectually improved soil environment, enhanced crop stress resistance to waterlogging, and increased grain yield of waterlogged maize. In order to explore the responses of nitrogen (N) efficiency and antioxidant system of summer maize to waterlogging stress under different tillage, a field experiment was conducted to explore N use efficiency, leaf activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and malondialdehyde (MDA) content of waterlogged maize Denghai 605 (DH605) and Zhengdan 958 (ZD958) under different tillage system (ridge planting and flat planting). Our results showed that ridge tillage was beneficial to ameliorate waterlogging damages on antioxidant system by increasing SOD, POD, and CAT activities, and decreasing MDA content. Moreover, ridge tillage significantly increased N efficiency of waterlogged maize. N translocation amount (NTA), N translocation efficiency (NTE), N contribution proportion (NCP), N harvest index (NHI), and N use efficiency (NUE) of waterlogging treatment under ridge planting system (W-V3+R) for DH605 was increased by 108%, 69%, 60%, 8% and 16%, while ZD958 increased by 248%, 132%, 146%, 13% and 16%, respectively, compared to those of waterlogging treatment under flat planting system (W-V3). Ultimately, ridge tillage led to a significant yield improvement by 39% and 50% for DH605 and ZD958, respectively, compared to that of W-V3. In conclusion, ridge tillage was conducive to retard leaf aging, and enhance nitrogen efficiency, thereby resulting in a yield improvement of waterlogged summer maize.

Plant population is an important attribute in crop management practice. Increasing the plant density by decreasing the crop row spacing was an alternative strategy to optimize crop profit. Hence, the field trial was conducted at Tamil Nadu Agricultural University, Coimbatore, during the winter season of 2017 – 18 to study the effect of row spacing on the growth and yield of cotton genotype TCH 1819. The experimental design was Randomized Block Design (RBD) with seven spacing treatments viz., T1: 60 x 15 cm (1,11,111 plants ha-1), T2: 60 x 20 cm (83,333 plants ha-1), T3: 75 x 15 cm (88,888 plants ha-1), T4: 75 x 20 cm (66,666 plants ha-1), T5: 75 x 30 cm (44,444 plants ha-1), T6: 90 x 15 cm (74074 plants ha-1), T7: 90 x 20cm (55,555 plants ha-1) and was replicated thrice.  Plant densities showed a significant (p=0.05) difference for all the characters studied.  The higher plant density of 1,11,111 plants (60 x 15 cm) observed significantly (p=0.05) maximum plant height (103.14 cm), Leaf Area Index (LAI) (4.35), Dry Matter Production (DMP) (8125 kg/ha), Crop Growth Rate (CGR) (6.58 g/m2/day), root length (41.46 cm), root dry weight (14.94 g/plant), and chlorophyll index (48.24).  The number of sympodial branches per plant (17) and bolls per plant (22 bolls) was found significant in the wider spacing of 75 x 30 cm.  The narrow spacing of 60 x 15 cm noted the highest seed cotton yield (2565 kg/ha), net return (R65706.62), and B: C (2.32) ratio, followed by the spacing of 75 x 15 cm due to more plant density per unit area (m2).  So, maximum yield in cotton can be achieved by decreasing the row spacing and increasing the plant population per unit area.

Modern almond growing travels on the tracks of super-high density (SHD). Born in 2010, it has already reached 6700 ha planted all over the world. This new cultivation system needs to define efficient agronomic techniques in order to identify it as a “Super-Efficient System”. Among these, the choice of cultivar is a crucial technique and a key factor for sustainability. The purpose of this study was to compare different cultivars in terms of vegetative, productive, and efficiencies parameters in order to gain applicable relevant knowledge about the SHD almond cultivation technique. For this, 3 years of research was carried out during 2017–2019, on a young almond grove made in 2014 with row spacing of 3.80 m × 1.20 m (2190 trees/ha), to evaluate the agronomic behavior of the two most planted cultivars in Italy, Guara-Tuono and Lauranne® Avijor, grafted on the Rootpac®20 dwarfing rootstock. The main biometric, productive, yield, mechanical harvesting efficiencies, and almond quality parameters were evaluated. Cv Lauranne® showed greater vigor, greater fruit yield, and damaged axes by mechanical harvesting, while higher values of yield efficiencies were observed for cv Tuono. Harvesting efficiency was related to canopy size and tree age. On the contrary, almonds quality parameters were strongly related to the cultivar, confirming the good performance of Tuono as varietal characters. Then, this cultivar seems to be the most suitable for an efficient SHD planting system, in line with the objectives of modern sustainable fruit growing. The better performance of cv Tuono could be related to the positive influence of the terroir as well.
