A field study was carried for two consecutive kharif and rabi seasons of 2013-14 and 2014-15 on farmer’s fields across 15 locations each year during kharif and 9 locations each year - during rabi in Srikakulam district, Andhra Pradesh. We tested five crop establishment methods viz., dry direct sowing using fertilizer-cum seed drill under irrigated conditions, drum seeding, systems of rice intensification (SRI), mechanized transplanting using rice 8 row yanmar transplanter, and manual transplanting. Study findings revealed that transplanting with rice planter emerged as high yielding method of establishment where the grain yield was higher by 9.21% over manual transplanting. Dry direct sowing was found to be highly profitable method of rice establishment by recording higher net returns Rs. 12596/ha compared to manual planting. Dry direct sowing and SRI proved as water productive rice establishment methods which took lesser water by 22.45% and 18.78% compared to manual transplanting during kharif. Whereas during rabi, drum seeding proved as profitable and water saving method of crop establishment in rice.

Poor early growth and uneven crop establishment are reported as the major bottlenecks in wide-scale adoption and optimal yield realization of dry direct-seeded rice (DSR). Seed priming can potentially help overcome these problems in DSR. Therefore, laboratory and field studies were conducted at Punjab Agricultural University, Ludhiana, India, during kharif/wet-season 2018 and 2019 to evaluate the effect of different priming techniques on germination, establishment, growth, and grain yield of rice under DSR conditions. The following priming treatments were evaluated: dry non-primed seed (control), hydropriming with distilled water, halopriming with 2.0% potassium nitrate, hormopriming with 50 ppm gibberellic acid (GA3), and osmopriming with polyethylene glycol (PEG)(−0.6 MPa), each with 12 and 24 h priming duration. In 2019, priming treatments were tested under two DSR establishment methods—conventional DSR (sowing in dry soil followed by irrigation) and soil mulch DSR (locally known as vattar DSR) (sowing in moist soil after pre-sowing irrigation), whereas in 2018, priming treatments were evaluated under conventional DSR only. In both years, halopriming and hormopriming resulted in a 7–11% increase in rice yields compared to non-primed dry seed (control). Osmopriming resulted in a 4% yield increase compared to control in 2018 but not in 2019. The higher yields in halopriming and hormopriming were attributed to higher and rapid germination/crop emergence, better root growth, and improvement in yield attributes. Priming effect on crop emergence, growth, and yield did not differ by DSR establishment methods and duration of priming. Conventional DSR and soil mulch DSR did not differ in grain yield, whereas they differed in crop emergence, growth, and yield attributes. These results suggest that halopriming with 2.0% potassium nitrate and hormopriming with 50 ppm GA3 has good potential to improve crop establishment and yield of rice in both conventional and soil mulch DSR systems.

<p>Water and fertilizer scarcity amid the increasing need of rice production challenges today’s agriculture. Integrated crop management (ICM) is a combination of water, crop, and nutrient management that optimizes the synergistic interaction of these components aiming at improving resource use efficiency, i.e. high productivity of water, land, and labor. The objectives of the study were to investigate the effects of crop establishment method, organic matter amendment, NPK management, and water management on yield of lowland rice. Five series of experiments were conducted at Sukamandi and Kuningan Experimental Stations, West Java. The first experiment was focused on crop establishment method, i.e. plant spacing and number of seedlings per hill. The second, third, and fourth experiments were directed to study the effect of NPK and organic matter applications on rice yield. The fifth experiments was designed to evaluate the effect of water management on rice yield. Results showed that 20 cm x 20 cm plant spacing resulted in the highest grain yield for the new plant type rice varieties. Organic matter and P fertilizer application did not significantly affect grain yield, but the yield response to P fertilization tended to be stronger with organic matter amendment. Split P application did not significantly increase grain yield. The use of a scale 4 leaf color chart reading resulted in a considerable N fertilizer saving without compromising rice yield. Intermittent irrigation technique saved water up to 55% without affecting yields, resulting in a 2-3 times higher water productivity.</p>

Abstract: Among the factors that affect seedling emergence and crop establishment are seed germination and vigor, which has an important influence on the establishment of the initial plant population and development, and may affect crop yield. Based on this background the objective of this research work was to evaluate the effects of seed vigor of common bean seed lots and its effects on crop grain yield. The treatments consisted of six seed lots of common bean, which were composed by different combinations of high and low vigor seeds. Seed lots were assessed by germination and vigor tests (first count of germination, electrical conductivity and accelerated aging). A field experiment was conducted in a randomized block design, with plots of six lines of five meters and were evaluated for grain yield at harvest. It was concluded that seed vigor affects common bean grain yield; the use of low vigor seeds results in grain yield reductions of up to 20%.

An experiment was conducted at the Bangladesh Rice Research Institute regional station, Rangpur to investigate the performances of different establishment methods of Boro rice; variety BRRI dhan29 in light texture soil during Boro 2004-05 and 2005-06 seasons. Five crop establishment methods were tested in a randomize complete block design with three replications. The methods were: 1. Conventional transplanting method 2. System of Rice Intensification (SRI) method, 3. Farmers practice, 4. Seedling throwing method and 5. Direct-Wet Seeded Rice(DWSR) using drum seeder method. Grain yield was influenced by different crop establishment methods in both the seasons. The highest mean grain yield was obtained by BRRI recommended conventional transplanting method (6.27 t ha-1) followed by SRI method (5.70 t ha-1). The highest number of panicles m-2 was obtained from wet DSR by drum seeder method (341 m-2). Effectiveness of tiller (92%) was obtained from the SRI method. The largest number of filled grains per panicle (76) was obtained from the SRI method. The highest 1000-grain weight (23.2 g) was obtained by the farmer’s method. Less sterility was occurred (30 %) from farmer’s methods. The highest growth duration (175 days) was observed in farmer method. But the highest field duration of BRRI dhan29 (145 days) was observed in wet DSR using dream seeder.

On Farm

Horsegram (Macrotyloma uniflorum) is sown late in the rainy season by resource-poor farmers in marginal, drought-prone areas of India. Sowing and early crop growth coincide with declining rainfall so crop establishment is often poor and yields are low. Horsegram is a ‘neglected’ crop and farmers' choice of varieties to grow is limited to poor-yielding landraces or to modern varieties for which access to seed is limited. In on-station trials, we compared the yield and relative merits over three years of seven varieties potentially suited to conditions in Jharkhand State and sown with or without priming by soaking seeds in water prior to sowing. Yield stability of the varieties was tested using data from these and five additional trials. Farmers' opinions were recorded during six participatory exercises based on farmers' trials, and their rankings were compared with those from the on-station evaluations. Significant variety × year interactions were observed and yield was generally inversely proportional to drought. Both linear and non-linear genotype × environment interactions were significant for all varieties. Variety BK 1 was the most desirable with stable yields across environments and a higher overall mean grain yield. Variety VLG 1 was unresponsive to more favourable environments but yielded more in the low yielding environments. However, it was the earliest to mature and was identified as a promising variety, which farmers preferred for its grain and brown seeds. This could be used to diversify farming systems with additional options for farmers. Although soaking seeds for 12 h was most effective in increasing germination in an in vitro study, soaking for 8 h before sowing increased emergence and final stand by 11 % and grain yield by 10 % averaged over all varieties and years. Soaking advanced flowering by 1.3 d and maturity by 1.9 d. All varieties responded positively to soaking and did so in all three years, although the response was stronger in drier years.

A study was carried out at the research farm of Hamelmalo Agricultural College during summer 2015 to study the effect of dates and methods of sowing with and without hydro-priming on growth, development and yield of sorghum. The experiment consisted of 2 factors- three dates of sowing viz.  D0 (Sowing before the onset of first summer rain, June 30), D1 (Sowing with the onset of first summer rains, July 7) and D2 (Sowing after the onset of summer rains, July 14) and three methods of sowing viz. SP (Direct sowing with hydro seed priming), TR (Transplanting) and DS (Direct sowing without hydro seed priming). The experiment was conducted in split plot design with 4 replications by keeping dates of sowing in the main plots and methods of sowing in the sub plots. The data on growth parameters, crop phenology, yield components and yield were recorded. The data was analysed using GENSTAT software and inferences were drawn by using LSD at 5% level of significance. Sowing methods significantly affected leaf area and leaf area index but sowing dates and their interaction with sowing methods did not show significant difference. Stand count, plant height, phenological parameters, thousand grain weight, grain and biomass yield were significantly affected by the sowing dates and methods but no significant difference in their interaction on all the parameters except in stand count and phenological parameters. Sowing before the onset of first summer rains (D0) resulted in significantly highest grain yield. Among the sowing methods, transplanting resulted in significantly higher grain yield seconded by direct sowing with hydro seed priming. Transplanting is less profitable and practicable as it is more laborious and difficult to apply in larger areas.

Gliricidia (Gliricidia sepium) seedlings are usually beneficial to corn crops when planted between corn rows. The objective of this work was to assess the effects of corn intercropped with gliricidia and "sabiá" (Mimosa caesalpiniifolia), a species native to the Brazilian northeastern region, on weed control and corn green ear and grain yields. The experiment was carried out at Estação Experimental da Universidade Federal Rural do Semi-Árido - UFERSA (Mossoró, State of Rio Grande do Norte, Brazil). The experimental design consisted of randomized complete blocks (multifactorial design) with five replications, arranged in split-plots. The plots consisted of corn cultivars AG1051 and BM 2022; subplot treatments (six) were no-hoeing, twice-hoeing (at 20 and 40 days after sowing) and intercropping with gliricidia and "sabiá", either directly sown or transplanted, simultaneously with corn sowing. The intercropped leguminous plants were spaced 0.40 m from each other, and directly seeded or transplanted (30-day-old seedlings) in between two 1 m-spaced corn rows. Twenty three weed species were identified during the experiment. Gliricidia seedlings were superior to "sabiá" seedlings with regard to plant height and survival rate. The highest corn green ear and grain yields were found for twice-hoed subplots, while the lowest yield was found for no-hoed or intercropped subplots. However, grain yield values in intercropped treatments did not differ from grain yield values in hoed plots. In addition, marketable husked green ear mean weights did not differ between twice-hoed subplots and subplots directly seeded with gliricidia and "sabiá". Such results indicated that corn benefited from the intercropping system, but intercropping with gliricidia and "sabiá" transplanted resulted in lower benefits than with the direct sowing of those species.
