“…2015; Devi et al, 2019;Promsomboon, 2019;Singh et al, 2020). The larger number of seedlings/hill increases competition for tiller formation, solar radiation interception, sunshine reception, nutrient uptake, photosynthesis rate and other physiological phenomena which eventually affect the growth and development of plants (Bozorgi et al, 2011).…”

Purple rice has become a fascinating source of nutritional value among healthy cereal grains. A field experiment was conducted at Bangladesh Agricultural University during the Rabi season (February to May) of 2021 to evaluate the effect of number of seedlings/hill on growth, yield attributes and yield of Purple rice. Three seedling densities, viz. 1, 2 and 3 seedlings/hill, and three rice cultivars, viz. Purple rice, Pahari rice and a check BRRI dhan67 were experimental treatments and the experiment was laid out in a split-plot design with three replications. Results revealed that seedling number/hill had significant effects on the growth, yield and yield attributes of rice cultivars. The tallest plant (136.31 cm) was observed from the transplanting of 1 seedling/hill followed by 2 seedlings/hill (133.35 cm) in Pahari rice. The maximum values of the number of effective tillers (13.47; Purple rice), flag leaf length and width (41.36 and 1.24 cm; Pahari rice) were recorded from the treatment 2 seedlings/hill. The longest panicle (26.58 cm; Pahari rice) was observed in 1 seedling/hill, statistically, a similar value was found with 2 seedlings/hill (24.44 cm). Among rice cultivars, BRRI dhan67 produced the heaviest grains (1000-seed weight 23.96 g) with 2 seedlings/hill and maximum grain yield (6.35 t/ha) with 1 seedling/hill. Single seedling/hill was found to be the best management practice to get a higher yield per unit area for Purple rice and other rice cultivars also.

“…Verification of the conclusions was accomplished by demonstration trials on the farm, which revealed that mechanically hill-seeded rice at such a density produced grain yields that were comparable to or significantly greater than transplanted rice. Devil et al [17] observed that the sky-high grain yield (1719 kg ha-1) in the 3 seedlings hill-1 (S-3) treatment was significantly more than all other treatments, whereas the lowest grain yield (1346 kg/ha) was in the 1 seedlings hill-1 treatment (S-1). Transplanting 15-day-old seedlings with 2 seedlings hill-1 (S-2) treatment yields the highest gross return (Rs 1.08,945 ha-1) and net return (Rs 69,536 ha-1) as well as the highest B:C ratio (1.76).…”

This study evaluated the sweet corn and vegetable soybeans intercropping system when applying various organic fertilizer sources and NPK fertilizer dosage. Conducted from June until August 2022 in Umbulharjo village, Yogyakarta, the study was carried out in factorial Randomized Complete Block Design under three replications. The first factor was density plant hill−1 consisting fourt levels (1+1; 2+1; 1+2; 2+2), the second was NPK dosage comprising three levels (100, 200, 300) kg ha−1, which eventually gained 42 units of plots. The observation variables involve components of yield, growth, and land efficiency. Variance test (ANOVA) at a value significant at 5% was used to analyze research data statistically and then followed by Duncan’s Multiple Range Test at the same significance level. The result indicated that applying a combination of chicken manure under NPK dosage of 300 kg ha−1 showed the sweet corn and vegetable soybean intercropping’s finest growth and yield, and the land efficiency component presented a Land Equivalent Ratio of 1.55 and Competition index of 0.92.

At present, we have adequate production of rice to fulfill the needs of humans. Now it is time to produce biofortified rice, whose grains contain enough amounts of nutrients like iron and boron. Two field experiments were carried out in Kharif 2019 and 2020 at Meerut (Uttar Pradesh), India, to find the effect of iron and boron nutrition on rice with different planting densities. The main plot treatment consists of three planting densities, and the subplot treatment consists of five foliar applications of micronutrients. They were tested in a split-plot design (SPD) with three replications. The results revealed that the rice transplanted with one seedling/hill gave the highest iron and boron content in grains and/or the crop fortified with iron and boron at 0.1 and 0.04% applied at the maximum tillering (MT) and panicle initiation (PI) stages of rice, respectively. The higher values of yield-contributing characters such as effective tillers/m2, panicle length (cm), grain weight/panicle (g), and test weight (g), as well as quality parameters such as nutrient content in grain (mg/kg), volume expansion ratio, protein content in grains (%), and amylose content (%) of rice were noticed in one seedling/hill except effective tillers/m2 during the first and second years. Application of Fe and B at the MT and PI stages of rice improved almost all the yield attributes and quality parameters. Planting density of two and three seedlings/hill was recorded at par values of grain yield, followed by one seedling/hill. Rice transplanted with three seedlings/hill obtained an average of 10.1 and 10.6% more grain yield than one seedling/hill during the first and second years, respectively. However, the application of Fe at 0.1% and B at 0.04% during both stages through foliar spray resulted in the highest seed yield and showed parity with the application of iron at 0.1% at the MT stage and boron at 0.04% at the PI stage. Economics revealed that the planting density of three seedlings/hill gave the maximum net returns of 61,585 and 66,752 ₹/ha with a benefit–cost ratio of 2.12 and 2.19 during 2019 and 2020, respectively. Furthermore, the highest net returns (62,188 and 67,938 ₹/ha) and benefit–cost ratio (2.15 and 2.23) were observed from the treatment of iron at 0.1% and boron at 0.04% at the MT and PI stages during the first and second years, respectively.
